Left ventricular aneurysm with predominating congestive heart failure. A comparative study of medical and surgical treatment

From 1979 to 1985, 109 patients were treated for congestive heart failure caused by postinfarction left ventricular aneurysm. Congestive heart failure was predominant in all patients at the time of diagnosis, 73% of whom were in Functional Class III or IV. Left ventricular end-diastolic pressure averaged 23.8 +/- 0.8 mm Hg (mean +/- standard error of the mean), total ejection fraction 29.7% +/- 1.0%, and telediastolic volume of the aneurysm 76.2 +/- 5.8 ml. Aneurysmectomy was performed in 49 patients (45%), whereas the remaining 60 patients were treated medically. The two groups did not differ in regard to clinical and hemodynamic data on admission, except for a more extensive coronary artery disease in the surgical group. Follow-up was obtained for all patients (100%) and averaged 48 +/- 3 months. Actuarial survival curves were similar, and the 5-year survival rates for surgical and medical groups were 70 +/- 7% and 64% +/- 7%, respectively (not significant). However, the 5-year complication-free rate was significantly (p = 0.05) higher among surgical patients (52% +/- 8%) than among the medical group (31% +/- 7%). Multivariate analysis showed the following variables to influence survival independently (p less than 0.05): contractile segment ejection fraction, right ventricular failure, antecedents of cardiac arrest or cardiogenic shock, and corrected contractile score. Independent variables decreasing the risk of cardiac-related complications and death (p less than 0.05) were as follows: surgical treatment, shorter interval between initial infarction and diagnosis of aneurysm, and absence of right ventricular failure. Functional improvement was directly related to surgical treatment and to residual segment contractile score (p less than 0.05). Thus, in patients with congestive heart failure caused by left ventricular aneurysm, surgical treatment improved the quality of life and prognosis for cardiac-related complications, but did not increase overall survival, compared to medical management of similar patients.     

Factors predicting failure of medical therapy for gastric ulcers

We reviewed the charts of all patients admitted with a diagnosis of gastric ulcer from January 1970 to December 1980. Multiple risk factors were recorded in patients receiving medical treatment and compared in those patients successfully treated medically versus those requiring operation after a failed course of medical treatment. One hundred patients were treated medically without surgical intervention, and 34 patients underwent operation after medical therapy failed. Significant risk factors in patients requiring operative therapy included smoking (p = 0.03), multiple trauma and sepsis (p = 0.02), large ulcers (p = 0.03), and multiple ulcers (p = 0.02). We have identified a set of factors associated with a high risk of failure of medical therapy. Patients with any of these risk factors may be treated most effectively by a limited trial of medical therapy with close follow-up. If their ulcer disease does not respond readily to standard medical therapy, they should be considered for early elective surgery.     

Improved survival of surgically treated patients with triple vessel coronary artery disease and severe angina pectoris. A report from the Coronary Artery Surgery Study (CASS) registry

We examined survival rates during a 6-year follow-up of patients in the registry of the Coronary Artery Surgery Study who had three vessel coronary artery disease and Canadian Cardiovascular Society class III-IV angina pectoris. All patients had a stenosis of 70% or greater in either the mid or proximal segment of all three coronary arteries. There were 679 medically treated patients and 1921 surgically treated patients in this nonrandomized comparison. Patients were stratified by left ventricular wall motion score and number of proximal coronary artery stenoses; after adjustment for these variables, the estimated probability of being alive at 6 years was 82% for surgically treated patients and 59% for medically treated patients (p less than 0.0001). Among patients with the most severe left ventricular dysfunction (left ventricular wall motion score of 16 to 30), the 6-year survival rate was 63% for surgically treated patients and 30% for medically treated patients (p less than 0.0001). Those with three proximal lesions (all gradations of left ventricular score) had an 81% 6-year survival rate with surgical treatment and 40% with medical treatment (p less than 0.0001). Ninety percent of surgically treated patients with normal ventricular function were living at 6 years and 78% of medically treated patients (p less than 0.0001). Among these patients, the survival rate was significantly better after surgical treatment than after only medical treatment if two or three proximal stenoses were present. If no proximal lesions were present (all categories of left ventricular function), 84% of surgically treated patients and 67% of medically treated patients were alive at 6 years (p less than 0.0001). In a multivariate (Cox) analysis of preoperative clinical, hemodynamic, and angiographic factors, early operation was a strong predictor of survival (estimated relative risk 0.38).     

Spinal epidural abscesses: risk factors,medical versus surgical management,a retrospective review of 128 cases

Background contextSpinal epidural abscess (SEA) is a rare, serious and increasingly frequent diagnosis. Ideal management (medical vs. surgical) remains controversial.PurposeThe purpose of this study is to assess the impact of risk factors, organisms, location and extent of SEA on neurologic outcome after medical management or surgery in combination with medical management.Study designRetrospective electronic medical record (EMR) review.Patient sampleWe included 128 consecutive, spontaneous SEA from a single tertiary medical center, from January 2005 to September 11. There were 79 male and 49 female with a mean age of 52.9 years (range, 22–83).Outcome measuresPatient demographics, presenting complaints, radiographic features, pre/post-treatment neurologic status (ASIA motor score [MS] 0–100), treatment (medical vs. surgical) and clinical follow-up were recorded. Neurologic status was determined before treatment and at last available clinical encounter. Imaging studies reviewed location/extent of pathology.MethodsInclusion criteria were a diagnosis of a bacterial SEA based on radiographs and/or intraoperative findings, age greater than 18 years, and adequate EMR. Exclusion criteria were postinterventional infections, Pott's disease, isolated discitis/osteomyelitis, treatment initiated at an outside facility, and imaging suggestive of a SEA but negative intraoperative findings/cultures.ResultsThe mean follow-up was 241 days. The presenting chief complaint was site-specific pain (100%), subjective fevers (50%), and weakness (47%). In this cohort, 54.7% had lumbar, 39.1% thoracic, 35.9% cervical, and 23.4% sacral involvement spanning an average of 3.85 disc levels. There were 36% ventral, 41% dorsal, and 23% circumferential infections. Risk factors included a history of IV drug abuse (39.1%), diabetes mellitus (21.9%), and no risk factors (22.7%). Pathogens were methicillin-sensitive Staphylococcus aureus (40%) and methicillin-resistance S aureus (30%). Location, SEA extent, and pathogen did not impact MS recovery. Fifty-one patients were treated with antibiotics alone (group 1), 77 with surgery and antibiotics (group 2). Within group 1, 21 patients (41%) failed medical management (progressive MS loss or worsening pain) requiring delayed surgery (group 3). Irrespective of treatment, MS improved by 3.37 points. Thirty patients had successful medical management (MS: pretreatment, 96.5; post-treatment, 96.8). Twenty-one patients failed medical therapy (41%; MS: pretreatment, 99.86, decreasing to 76.2 [mean change, ?23.67 points], postoperative improvement to 85.0; net deterioration, ?14.86 points). This is significantly worse than the mean improvement of immediate surgery (group 2; MS: pretreatment, 80.32; post-treatment, 89.84; recovery, 9.52 points). Diabetes mellitus, C-reactive protein greater than 115, white blood count greater than 12.5, and positive blood cultures predict medical failure: None of four parameters, 8.3% failure; one parameter, 35.4% failure; two parameters, 40.2% failure; and three or more parameters, 76.9% failure.ConclusionEarly surgery improves neurologic outcomes compared with surgical treatment delayed by a trial of medical management. More than 41% of patients treated medically failed management and required surgical decompression. Diabetes, C-reactive protein greater than 115, white blood count greater than 12.5, and bacteremia predict failure of medical management. If a SEA is to be treated medically, great caution and vigilance must be maintained. Otherwise, early surgical decompression, irrigation, and debridement should be the mainstay of treatment.     

Gastroesophageal reflux after repair of atrioventricular septal defect in infants with trisomy 21: a comparison of medical and surgical therapy.

BACKGROUND: Gastroesophageal reflux and dysmotility are common in children with trisomy 21. Children with trisomy 21 and congenital heart disease are at increased risk for complications of gastroesophageal reflux even after repair of their cardiac abnormalities. The optimal management of reflux in these patients is not known. METHODS: The authors studied 24 consecutive infants (5.3+/-3.1 months) with trisomy 21 and atrioventricular septal defect who had symptoms or signs of gastroesophageal reflux and a positive esophageal pH study finding early after repair of their cardiac anomaly. Ten patients were given standardized medical therapy with upright positioning during and after feedings, thickening of feedings, metoclopramide, and an H2-receptor antagonist. The other 14 underwent primary surgical management consisting of Nissen fundoplication through a minilaparotomy. RESULTS: All 10 medically treated patients required readmission within 2 weeks for complications related to reflux, including aspiration or pneumonia (n = 6), persistent failure to thrive (n = 2), and frequent apneic episodes (n = 2). No surgically treated patients had reflux-related complications requiring readmission. The total duration of hospitalization in the medically treated patients, including the initial hospitalization and the rehospitalization, was significantly longer than in patients who underwent fundoplication (35.8+/-9.8 v. 10.4+/-2.2 days, P<.001). At follow-up (24 to 56 months), all patients were alive except for 1 medically treated patient who died of aspiration pneumonia 28 days after readmission. Two medically treated patients required a Nissen, and 3 patients in the surgical group underwent redo fundoplication, all within 1 year. Three other patients in the medically treated group required a total of 8 hospitalizations for complications of reflux. No patient in either group required placement of a gastrostomy tube. Weight percentile for age was higher in surgical than medical patients. CONCLUSIONS: Infants with trisomy 21 and atrioventricular septal defect who undergo fundoplication are less likely to experience major complications of reflux early after cardiac surgery than those treated with a medical regimen of upright posture, thickened feedings, metoclopramide, and H2-receptor blockade.     

A comparative synchronous coronary surgery survival study.

Utilizing patient criteria published by the Veterans Administration Cooperative (VAC) Study, a cohort of 229 surgically treated patients was retrieved from the Milwaukee Cardiovascular Data Registry. These patients were all operated on by one surgeon during 1972 to 1974. Four-year survival of this group was compared with that of the medically treated cohort of 310 patients from the VAC Study. Operative mortality was included in all surgical groups. The cumulative 4-year survival of both groups revealed a 95 to 85% advantage for surgical therapy. In patients with three-vessel disease, the cumulative survival favored surgical therapy--94% compared with 80% in the medically terated cohort--and in patients with triple-vessel disease and a normal left ventricle, surgical therapy again showed better results: 100% compared with 88%. Patients with two-vessel disease and a normal left ventricle who underwent surgical intervention had slightly better 4-year survival than those who had medical treatment--100% versus 95%--and those with two-vessel disease and an abnormal left ventricle had a 93% survival after surgical treatment compared with 84% for those with medical treatment. For patients with single-vessel disease, there was no difference in survival between the surgical and medical cohorts.     

Current multimodality management of infectious intracranial aneurysms

OBJECTIVE: To implement an algorithm for and assess multimodality (medical, endovascular, and microsurgical) treatment of patients with infectious intracranial aneurysms. METHODS: Twenty patients with 27 infectious aneurysms were treated during a 10-year period. Bacterial endocarditis was the most common cause (65%). Most aneurysms presented with rupture (75%), and the middle cerebral artery was the most common location (70%). RESULTS: Five patients were treated endovascularly, with direct coiling for three patients and parent artery occlusion for two patients. Ten patients (15 aneurysms) were treated surgically, with 6 aneurysms being trapped/resected, 2 trapped/bypassed, 4 clipped, and 3 wrapped. Five patients were treated medically. Treatment-associated neurological morbidity was observed for two patients (10%), and two patients died (10%). Good outcomes were observed for 16 patients (80%). CONCLUSION: Factors that guide management decisions for these patients include aneurysm rupture, hematomas with increased intracranial pressure, and the eloquence of brain tissue supplied by the parent artery. Patients with unruptured infectious aneurysms are initially treated medically, with antibiotics and serial angiography. Patients with ruptured aneurysms that are not associated with hematomas and that do not involve eloquent vascular territory are treated endovascularly. Patients with ruptured aneurysms are treated surgically when there is a hematoma or the risk of ischemic complications in eloquent territory. Therefore, endovascular therapy is the first option for patients in stable condition with ruptured aneurysms; surgical therapy is the first option for patients in unstable condition with ruptured aneurysms and the second option for patients in stable condition who experience failure of endovascular therapy. Medically treated patients with enlarging or dynamic unruptured aneurysms also require direct surgical or endovascular intervention. Favorable patient outcomes can be achieved with this multimodality management.     

Management of patients with intramural hematoma involving the ascending aorta

OBJECTIVE: Although intramural hematoma of the aorta is considered a unique pathologic entity, the management of intramural hematoma involving the ascending aorta (type A) has not been well established. The purpose of this study was to establish the optimal mode of management of type A intramural hematoma. METHODS: We treated patients with type A intramural hematoma as follows. Early operation was carried out only for patients with cardiac tamponade, impending rupture, or rupture. Other patients were treated medically, but patients with progression of intramural hematoma during medical follow-up had their treatment converted to surgery. From February 1992 to March 2001, a total of 33 patients with type A intramural hematoma were treated as described here. Patients were divided according to initial treatment into an early surgery group (n = 9) and a medical treatment group (n = 24). Clinical profiles and in-hospital and long-term survival rates were compared between the groups. RESULTS: Compared with the early surgery group, the medical treatment group was younger (64.2 +/- 7.0 years vs 71.7 +/- 8.5 years, P =.0319) and had a greater number of involved segments (3.6 +/- 0.6 vs 3.0 +/- 0.9, P =.0395). Eight patients in the medical treatment group were switched to surgery during follow-up because of progression of intramural hematoma. In-hospital mortality rates in the early surgery and medical groups were 11% and 5% (P =.477), respectively. Cumulative 1- and 2-year survivals were 89% and 89%, respectively, in the early surgery group, and 92% and 81%, respectively, in the medical group (P =.49). CONCLUSION: We concluded that about 70% of type A intramural hematomas could be managed expectantly, and more than 50% could be treated medically alone.     

Predictors of attrition in a multidisciplinary adult weight management clinic

Background

Worldwide, more than 1.7 billion individuals may be classified as overweight and are in need of appropriate medical and surgical treatments. The primary goal of a comprehensive weight management program is to produce sustainable weight loss. However, for such a program to be effective, the patient must complete it. We analyzed attrition rates and predictors of attrition within a publicly funded, multi-disciplinary adult weight management program.

Methods

We retrospectively reviewed charts from an urban multidisciplinary adult weight management clinic program database. Patients received medical or surgical treatment with appropriate follow-up. We collected information on demographics and comorbidities. Patients in the surgical clinics received either laparoscopic gastric band insertion or gastric bypass. We conducted univariate analysis and multivariate analyses on predictors of attrition.

Results

A total of 1205 patients were treated in the weight management program: 887 in the medical clinic and 318 with surgery and follow-up in a surgical clinic. Overall, 516 patients left the program or were lost to follow-up (attrition rate 42.8%). The attrition rate was 53.9% in the medical clinic and 11.9% in the surgical clinic. Multivariate analyses identified participation in the medical clinic, younger patient age and lower body mass index as predictors of attrition.

Conclusion

We found lower attrition rates among surgically than medically treated patients in a multidisciplinary weight management clinic. Further research is needed to understand those variables that lead to improved attrition rates.     

Health care utilization after medical and surgical therapy for gastroesophageal reflux disease: a population-based study, 1996 to 2000

HYPOTHESIS: Patients who undergo surgical treatment for gastroesophageal reflux disease (GERD) will use fewer health care resources than those who continue to be treated medically during the same follow-up period. DESIGN: Matched cohort study of patients with a diagnosis of GERD receiving surgical therapy or medical therapy. SETTING: Tennessee Medicaid (TennCare) program from 1996 through 2000. PATIENTS: Population-based sample of 7635 TennCare enrollees with a diagnosis of GERD served as the underlying population. Of these, 111 surgical patients who underwent fundoplication in 1996 met inclusion criteria. The 200 patients in the medically treated cohort were randomly matched to patients in the surgical cohort by demographic characteristics and previous use of acid-suppressing drugs. INTERVENTIONS: The surgical group all underwent fundoplication in 1996. The medical group was treated without fundoplication. MAIN OUTCOME MEASURES: Health care utilization (medication use, outpatient visits, hospitalizations, and diagnostic studies) for each cohort through December 2000. RESULTS: In the 4-year follow-up period, the surgical group had fewer GERD-related outpatient physician visits (5.5 +/- 6.9 visits vs 6.7 +/- 6.1 visits; P =.10). Utilization of other types of outpatient and inpatient care was similar. During each year of follow-up, the proportion of persons using GERD medication was lower in the surgical group. (0.67 vs 0.93 in year 1, 0.67 vs 0.91 in year 2, 0.72 vs 0.85 in year 3, and 0.74 vs 0.90 in year 4). CONCLUSION: The utilization of health care resources in patients treated surgically for GERD is associated with a modest decrease in the use of GERD-related medications and GERD-related visits.     

Independent predictors of failure of nonoperative management of spinal epidural abscesses

Background contextThe notion that all patients with spinal epidural abscess (SEA) require surgical decompression has been recently challenged by reports of successful medical management of select patients with SEA.PurposeThe purpose of this study was to identify the independent variables that determine success or failure of medical management of SEA.Study design/settingThis was a retrospective, case-control study.Patient samplePatients 18 years or older with diagnosis of SEA admitted to our institution during the study period were included in the sample.Outcome measuresThe outcome measure was successful management of SEA by eradication of the infection without worsening of neurologic deficits.MethodsAll patients admitted to our health-care system with a diagnosis of SEA from 1993 to 2011 were identified and the data were retrospectively collected. Patients 18 years or older diagnosed with SEA were included. Excluded were those with postsurgical SEA or phlegmon without an abscess and those with a complete spinal cord injury from SEA for longer than 48 hours.ResultsA total of 355 patients with average age of 60 years met our inclusion criteria. Of the patients who initially underwent nonoperative treatment, 54 patients failed medical management and 73 patients were successfully treated without surgery. Univariate and multivariate analysis identified incomplete or complete spinal cord deficits as the most significant risk factor for failure of medical management. Age older than 65 years, diabetes, and methicillin-resistant Staphylococcus aureus (MRSA) were also independent risk factors for failure. An algorithm for probability of failed antibiotic management of spinal epidural abscess predicted 99% probability of failure for patients with all four of these risk factors.ConclusionsSEA treated with medical management alone has a very high risk for failure if the patient is older than 65 years with diabetes, MRSA infection, or neurologic compromise. In the absence of these risk factors, nonoperative management of spinal epidural abscess may be considered as the initial line of treatment with close monitoring.     

Time to first new myocardial infarction in patients with severe angina and three-vessel disease comparing medical and early surgical therapy: a CASS registry study of survival

We compared time to first new myocardial infarction during a 6-year follow-up in patients in the registry of the Coronary Artery Surgery Study who had three-vessel coronary artery disease and Canadian Cardiovascular Society Class III-IV angina pectoris. There were 679 medically treated patients and 1921 surgically treated patients in this nonrandomized comparison. A broad definition of myocardial infarction incorporating electrocardiographic and clinical criteria was used to include as many new infarctions as possible. Patients were stratified by left ventricular wall motion score and number of proximal coronary artery stenoses; after adjustment for these variables, 86% of surgical and 73% of medical patients were free of new myocardial infarction at 6 years (p less than 0.0001). This advantage of surgical treatment was observed in subgroups of patients with at least one proximal 70% (or greater) stenosis in the left anterior descending coronary artery and moderate or severe impairment of left ventricular function, as well as those patients with two proximal coronary artery narrowings. In a multivariate (Cox) analysis of preoperative clinical, hemodynamic, and angiographic factors, early operation was the strongest predictor of freedom from new myocardial infarction.     

Bronchiectasis in urban black children

From July 1979 to July 1982, 29 cases of childhood bronchiectasis were encountered at Leratong Hospital. They were retrospectively divided into two groups: 16 patients underwent surgical intervention and the other 13 patients received medical treatment only. Symptoms and signs were reviewed and findings on bronchography were studied. The left lower lobe was the most common site of involvement, and the lingular segment was invariably also affected by bronchiectatic changes. Ten of the surgical patients (63%) underwent pneumonectomy. In 75% of the surgical group there was an excellent or good result after surgery, while a good result was achieved in 40% of those receiving medical treatment only. We have reviewed other large series to compare surgical and medical management, and discuss factors that may influence the outcome of surgical treatment.     

Consideration of management of type B dissecting aneurysms of the thoracic aorta: clinical comparative study between surgical and medical treatments

Between 1970 and 1989, 116 patients with type B dissecting aneurysms of the thoracic aorta were seen in our institution and affiliated hospitals. The patients were classified into 5 groups according to the acuity (acute vs chronic) and modes of therapy (surgical vs medical). Group I: 24 patients with acute B dissection were treated surgically during the acute stage. Group II: 21 patients with acute B dissection were initially treated with intensive medical therapy and followed by elective operation during the subacute stage. Group III: 22 patients with acute B dissection were treated medically. Group IV: 42 patients with chronic dissection were treated surgically. Group V: 7 patients with chronic B dissection were treated medically. The 5-year survival rates including early mortality were 70.5 +/- 9.4% for Group I, 88.9 +/- 7.5% for Group II, 68.3 +/- 11.2% for Group III, 64.6 +/- 8.4% for Group IV and 71.4 +/- 17.1% for Group V. The 5-year survival rates of Group II was significantly better than those of Group I, III and IV, respectively. The present data suggests that acute type B dissection without complications (bleeding, visceral or lower limbs ischemia) should be treated initially with intensive medical therapy and then followed by elective operation during the subacute stage, if the false lumen were not thrombosed.     

Randomized prospective matched pair study comparing peritoneovenous shunt and conventional therapy in massive ascites.

A prospective randomized matched pair study was designed to test the efficacy of the peritoneovenous (LeVeen) shunt as a treatment for massive cirrhotic ascites compared with traditional medical therapy. Patients who failed to lose weight while on a low salt diet and fluids restricted to 1000 ml daily were placed in the study group. Weight loss, decrease in abdominal girth and diuresis were significantly greater (P less than 0.01) for surgical patients than for their medically treated counterparts. The surgical technique is simple, quick and inexpensive. The surgical patients outlived their matched partners in 12 of 14 pairs where a definitive comparison was possible (P less than 0.02). The median stay in hospital after randomization was shortened from 32 days with medical therapy to 15 days for those undergoing the shunt operation. Those treated medically experienced a significant rise in mean blood urea nitrogen and K+ (P less than 0.02). Patients with alcoholic hepatitis, hyperbilirubinaemia (bilirubin greater than 154 mumol/l), peritoneal sepsis, severe coagulopathy and those who had recently bled from oesophageal varices are poor risks for the surgical procedure.     

Management of aneurysms involving branches of the celiac and superior mesenteric arteries: a comparison of surgical and endovascular therapy

OBJECTIVE: Aneurysms involving branches of the superior mesenteric and celiac arteries are uncommon and require proper management to prevent rupture and death. This study compares surgical and endovascular treatment of these aneurysms and analyzes outcome. METHODS: Patients at the Mount Sinai Medical Center in New York who were treated for aneurysms in the branches of the celiac artery and superior mesenteric artery were identified through a search of the institution's medical records and endovascular database. Patient demographics, history, clinical presentation, aneurysm characteristics, treatments, and follow-up outcome were retrospectively recorded. Significant differences between patients treated by surgical or endovascular therapy were determined by using Student's t test and chi2 analysis. RESULTS: Between January 1, 1991, and July 1, 2005, 59 patients with 61 aneurysms were treated at a single institution. Twenty-four patients had surgical repair, and 35 underwent endovascular treatment, which included coil embolization and stent-graft therapy. Splenic (28) and hepatic (22) artery aneurysms predominated. Eighty-nine percent of splenic artery aneurysms were true aneurysms and were treated by endovascular and surgical procedures in near equal numbers (14 and 11, respectively). Pseudoaneurysms were significantly more likely to be treated by endovascular means (P < .01). The technical success rate of endovascular treatment for aneurysms was 89%, and failures were successfully treated by repeat coil embolization in all patients who presented for retreatment. Patients treated by endovascular techniques had a significantly higher incidence of malignancy than patients treated with open surgical techniques (P = .03). Furthermore, patients treated by endovascular means had a shorter in-hospital length of stay (2.4 vs 6.6 days, P < .001). CONCLUSION: Endovascular management of visceral aneurysms is an effective means of treating aneurysms involving branches of the celiac and superior mesenteric arteries and is particularly useful in patients with comorbidities, including cancer. It is associated with a decreased length of stay in the elective setting, and failure of primary treatment can often be successfully managed percutaneously.     

Management of Bowel Obstruction in Patients with Stage IV Cancer: Predictors of Outcome After Surgery

Background

Patients with stage IV cancer and bowel obstruction (BO) present a complicated management problem. We sought to determine if specific parameters could predict outcome after surgery.

Methods

Records of patients with stage IV cancer and BO treated from 1991 to 2008 were reviewed. For surgical patients, 30-day morbidity and 90-day mortality were assessed using exact multivariable logistic regression methods.

Results

Of 198 patients, 132 (66.7 %) underwent surgery, 66 medical treatment alone, and demographics were similar. A total of 41 patients (20.7 %) were diagnosed with stage IV cancer and BO synchronously, all treated surgically; the remaining presented metachronously. Medically managed patients were more likely to have received chemotherapy in the 30 days prior to BO (45 of 66 [68.2 %] vs 40 of 132 [30.3 %], p < .01). In the surgical group, 30-day morbidity was 35.6 %, while 90-day mortality was 42.3 %. Median overall survival for synchronous patients was 14.1 months (95 % confidence interval [95 % CI] 7.6–23.2), and 3.7 months (95 % CI 2.5–5.2) and 3.6 months (95 % CI 1.5–5.2) for metachronous patients treated surgically and medically, respectively. A multivariate model for 90-day surgical mortality identified low serum albumin, metachronous presentation, and ECOG > 1 as predictors of death (p < .05). A model for 30-day surgical morbidity yielded low hematocrit as a predictive factor (p < .05).

Conclusions

This cohort identifies characteristics indicative of morbidity and mortality in stage IV cancer and BO. Low serum albumin, ECOG > 1, and metachronous presentation predicted for 90-day surgical mortality. These data suggest factors that can be used to frame treatment discussion plans with patients.     

Long-term follow-up of atherosclerotic renovascular disease. Beneficial effect of ACE inhibition.

BACKGROUND: Patients with atherosclerotic renovascular disease (ARVD) are almost invariably treated by revascularization. However, the long-term outcomes of this approach on survival and progression to renal failure have not been investigated and have not been compared with that of a purely medical treatment. The aim of this observational study was to investigate factors affecting long-term (over 5 years) outcome, survival and renal function of patients with ARVD treated invasively or medically. METHODS: ARVD was demonstrated angiographically in 195 patients who were consecutively enrolled into a follow-up study. Patient age was 65.6+/-11.2 years, serum creatinine was 1.74+/-1.22 mg/dl and renal artery lumen narrowing was 73.5+/-17.5%. A revascularization was performed in 136 patients, whereas 54 subjects having comparable characteristics were maintained on a medical treatment throughout the study; five patients were lost during follow-up. RESULTS: The main follow-up was 54.4+/-40.4 months. The assessment of cardiovascular survival and renal survival at the end of follow-up revealed 46 cardiovascular deaths, 20 patients with end-stage renal disease (ESRD) and 41 patients with an increase in serum creatinine of over one-third. The multivariate analysis showed that renal revascularization did not affect mortality or renal survival compared with medical treatment. Revascularization produced slightly lower increases in serum creatinine and a better control of blood pressure. A longer survival was associated with the use of angiotensin-converting enzyme inhibitors (ACEIs) (P = 0.002) in both revascularized and medically treated patients. The only significant predictor of ESRD was an abnormal baseline serum creatinine. CONCLUSIONS: On long-term follow-up, ARVD was associated with a poor prognosis due to a high cardiovascular mortality and a high rate of ESRD. In our non-randomized study, revascularization was not a major advantage over medical treatment in terms of mortality or renal survival. The use of ACEIs was associated with improved survival.     

Endoscopic surgery versus medical treatment for spontaneous intracerebral hematoma: a randomized study

A controlled randomized study of endoscopic evacuation versus medical treatment was performed in 100 patients with spontaneous supratentorial intracerebral (subcortical, putaminal, and thalamic) hematomas. Patients with aneurysms, arteriovenous malformations, brain tumors, or head injuries were excluded. Criteria for inclusion were as follows: patients' age between 30 and 80 years; a hematoma volume of more than 10 cu cm; the presence of neurological or consciousness impairment; the appropriateness of surgery from a medical and anesthesiological point of view; and the initiation of treatment within 48 hours after hemorrhage. The criteria of randomization were the location, size, and side of the hematoma as well as the patient's age, state of consciousness, and history of hypertension. Evaluation of outcome was performed 6 months after hemorrhage. Surgical patients with subcortical hematomas showed a significantly lower mortality rate (30%) than their medically treated counterparts (70%, p less than 0.05). Moreover, 40% of these patients had a good outcome with no or only a minimal deficit versus 25% in the medically treated group; the difference was statistically significant for operated patients with no postoperative deficit (p less than 0.01). Surgical patients with hematomas smaller than 50 cu cm made a significantly better functional recovery than did patients of the medically treated group, but had a comparable mortality rate. By contrast, patients with larger hematomas showed significantly lower mortality rates after operation but had no better functional recovery than the medically treated group. This effect from surgery was limited to patients in a preoperatively alert or somnolent state; stuporous or comatose patients had no better outcome after surgery. The outcome of surgical patients with putaminal or thalamic hemorrhage was no better than for those with medical treatment; however, there was a trend toward better quality of survival and chance of survival in the operated group.     

Nonunion of the proximal humerus. A review of 25 cases

Records of 25 patients with nonunion of the proximal humerus were reviewed retrospectively. The initial fractures included 19 two-part surgical neck fractures and six three-part fractures. Fourteen fractures were treated nonoperatively and 11 surgically. Nine of 11 of the initial internal fixations were unsatisfactory. At the time of fracture 16 patients had one or more significant medical illnesses. Nonunion of the proximal humerus was associated with considerable morbidity. Patients complained of pain, stiffness, and disability in association with shoulder dysfunction. Four treatment groups were evaluated. Patients who declined treatment and patients treated with nonreamed intramedullary nails had limited shoulder motion and pain without union. Patients treated with proximal humeral hemiarthroplasty had relief of pain but limited motion despite rotator cuff reconstruction. The best results of treatment occurred after open reduction with internal fixation and bone grafting. A tension band construction that fixed the rotator cuff and proximal humerus to a plate/shaft composite was used successfully in seven patients. Although satisfactory reconstruction of nonunion of the proximal humerus can be obtained, the results of treatment in this series were only fair. Only 48% (12 of 25 patients) had good results.
