BackgroundDeep sternal wound infection (DSWI) is a rare but severe complication after cardiac surgical procedures and has been associated with increased early morbidity and mortality. Studies reporting long-term outcomes in patients with DSWI have shown contradictory results. We performed a study-level meta-analysis evaluating the impact of DSWI on short- and long-term clinical outcomes.MethodsA systematic literature search was conducted to identify studies comparing short- and long-term outcomes of patients submitted to cardiac surgical procedures who developed DSWI and patients who did not. The primary outcome was overall mortality. Secondary outcomes were in-hospital mortality, follow-up mortality, major adverse cardiovascular events, myocardial infarction, and repeat revascularization. Postoperative outcomes were also investigated.ResultsTwenty-four studies totaling 407 829 patients were included. Overall, 6437 (1.6%) patients developed DSWI. Mean follow-up was 3.5 years. DSWI was associated with higher overall mortality (incidence rate ratio [IRR], 1.99; 95% CI, 1.66-2.38; P < .001), in-hospital mortality (odds ratio, 3.30; 95% CI, 1.88-5.81; P < .001), follow-up mortality (IRR, 2.02; 95% CI, 1.39-2.94; P = .001), and major adverse cardiovascular events (IRR, 2.04; 95% CI, 1.60-2.59; P < .001). No differences in myocardial infarction and repeat revascularization were found, but limited studies reported those outcomes. DSWI was associated with longer postoperative hospitalization, stroke, myocardial infarction, and respiratory and renal failure. Sensitivity analyses on isolated coronary artery bypass grafting studies and by adjustment method were consistent with the main analysis.ConclusionsCompared with patients who did not develop DSWI, patients with DSWI after cardiac surgical procedures had increased risk of death as well as short- and long-term adverse clinical outcomes.  相似文献

ObjectiveThe impact of new-onset postoperative atrial fibrillation (POAF) following coronary artery bypass grafting (CABG) surgery on long-term clinical outcomes and costs is not known. This subanalysis of the Veterans Affairs “Randomized On/Off Bypass Follow-up Study” compared 5-year outcomes and costs between patients with and without POAF.MethodsOf the 2203 veterans in the study, 100 with pre-CABG atrial fibrillation (93) or missing data (7) were excluded (4.8%). Unadjusted and risk-adjusted outcomes were compared between new-onset POAF (n = 551) and patients without POAF (n = 1552). Five-year clinical outcomes included mortality, major adverse cardiovascular events (MACE, comprising mortality, repeat revascularization, and myocardial infarction), MACE subcomponents, stroke, and costs. A stringent P value of ≤.01 was required to identify statistical significance.ResultsPatients with POAF were older and had more complex comorbidities. Unadjusted 5-year all-cause mortality was 16.3% POAF versus 11.9% no-POAF, P = .008. Unadjusted cardiac-mortality was 7.4% versus 4.8%, P = .022. There were no differences between groups in any other unadjusted outcomes including MACE or stroke. After risk adjustment, there were no significant differences between groups in 5-year all-cause mortality (POAF odds ratio, 1.19; 99% confidence interval, 0.81-1.75) or cardiac mortality (odds ratio, 1.51, 99% confidence interval, 0.88-2.60). Adjusted first-year post-CABG costs were $15,300 greater for patients with POAF, but 2- through 5-year costs were similar.ConclusionsNo 5-year risk-adjusted outcome differences were found between patients with and without POAF after CABG. Although first-year costs were greater in patients with POAF, this difference did not persist in subsequent years.  相似文献

ObjectivesSevere acute kidney injury (AKI) is a known risk factor for infection and mortality. However, whether stage 1 AKI is a risk factor for infection has not been evaluated in adults. We hypothesized that stage 1 AKI following cardiac surgery would independently associate with infection and mortality.MethodsIn this retrospective propensity score–matched study, we evaluated 1620 adult patients who underwent nonemergent cardiac surgery at the University of Colorado Hospital from 2011 to 2017. Patients who developed stage 1 AKI by Kidney Disease Improving Global Outcomes creatinine criteria within 72 hours of surgery were matched to patients who did not develop AKI. The primary outcome was an infection, defined as a new surgical-site infection, positive blood or urine culture, or development of pneumonia. Secondary outcomes included in-hospital mortality, stroke, and intensive care unit (ICU) and hospital length of stay (LOS).ResultsStage 1 AKI occurred in 293 patients (18.3%). Infection occurred in 20.9% of patients with stage 1 AKI compared with 8.1% in the no-AKI group (P < .001). In propensity-score matched analysis, stage 1 AKI independently associated with increased infection (odds ratio [OR]; 2.24, 95% confidence interval [CI], 1.37-3.17), ICU LOS (OR, 2.38; 95% CI, 1.71–3.31), and hospital LOS (OR, 1.30; 95% CI, 1.17-1.45).ConclusionsStage 1 AKI is independently associated with postoperative infection, ICU LOS, and hospital LOS. Treatment strategies focused on prevention, early recognition, and optimal medical management of AKI may decrease significant postoperative morbidity.  相似文献

ObjectiveUsing a large national database, we sought to better define the relationship between obesity measures and early clinical outcomes following mitral valve surgery for degenerative disease.MethodsFor the outcomes of in-hospital mortality, postoperative cerebrovascular event (CVA), and deep sternal wound infection (DSWI), a retrospective cohort study was performed using data acquired from the United Kingdom National Adult Cardiac Surgery Audit. Multivariable Cox proportional hazard regression modeling was used to investigate associations with individual measures of obesity. Progressively adjusted body mass index (BMI)-specific hazard ratios (HRs) were plotted against mean BMI values in each World Health Organization category using floated variances to investigate specific shapes of association.ResultsMultivariable Cox proportional hazard modeling failed to demonstrate an association between mortality and an increase in BMI of 5 points (HR, 0.93, 95% confidence interval [CI], 0.81-1.07), a BMI quintile increase (HR, 0.98; 95% CI, 0.90-1.07), or being classed “obese” by World Health Organization standards (HR, 1.03; 95% CI, 0.74-1.42). A 5-point BMI increase was associated with an increased hazard of DSWI (HR, 1.38; 95% CI, 1.08-1.77) but was not associated with perioperative CVA (HR, 1.05; 95% CI, 0.91-1.21). The shape of association between BMI and mortality appeared approximately U-shaped. DSWI appeared linear, whereas CVA demonstrated an inverted U, or a possible hourglass.ConclusionsAlthough individual measures of obesity were not associated with an increased mortality risk on regression modeling, the U-shaped relationship between mortality and increasing BMI demonstrates lower mortality risks in lower obesity classes. Increasing BMI was associated with an increased hazard for DSWI.  相似文献

BackgroundPerioperative anemia and transfusions are associated with adverse operative outcomes after coronary artery bypass graft surgery (CABG). Their individual association with long-term outcomes is unclear.MethodsPatients aged 65 years and older who had undergone CABG and were in The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (n = 504,596) from 2011 to 2018 were linked to Centers for Medicare and Medicaid Service data to assess long-term survival. The association of intraoperative anemia defined by intraoperative nadir hematocrit (nHct) and red blood cell (RBC) transfusions, and their interactions, on long-term mortality were assessed with Kaplan-Meier estimates and multivariable Cox regression. Restricted cubic splines were used to explore the association between nHct as a continuous variable and long-term mortality.Results258,398 on-pump CABG STS Adult Cardiac Surgery Database patients surviving the perioperative period were linked to Centers for Medicare and Medicaid Service claims files. Per World Health Organization criteria, 41% had preoperative anemia. Mean intraoperative nHct was 24%; RBC transfusion rate was 43.7%. Univariable analysis associated both RBC transfusion and lower nHct with worse survival. Lower nHct was only marginally associated with risk-adjusted mortality: adjusted hazard ratio (AHR) 1.04 (95% CI, 1.01-1.06) and 1.07 (95% CI, 1.00-1.14) at nHct 20% and at nHct 14%, respectively. RBC transfusion was associated with significantly higher adjusted mortality irrespective of timing of transfusion: AHR intraoperative 1.21 (95% CI, 1.18-1.27); AHR postoperative 1.26 (95% CI, 1.22-1.30); AHR both 1.46 (95% CI, 1.40-1.52) and across all levels of nHct. RBC transfusion was not associated with improved survival at any level of nHct.ConclusionsAmong Medicare CABG patients, RBC transfusions were associated with increased risk-adjusted late mortality across all levels of nHct whereas intraoperative anemia was only marginally so. Tolerance of lower intraoperative nHct than currently accepted may be preferable to transfusions.  相似文献

ObjectivesDialysis is a well-established risk factor for morbidity and mortality after cardiovascular procedures. However, little is known regarding the outcomes of proximal aortic surgery in this high-risk cohort.MethodsPerioperative (in-hospital or 30-day mortality) and 10-year outcomes were analyzed for all the patients who underwent open proximal aortic repair with the diagnosis of nonruptured thoracic aortic aneurysm (aneurysm, n = 325) or type A aortic dissection (dissection, n = 461) from 1987 to 2015 using the US Renal Data System database.ResultsIn patients with aneurysm, perioperative mortality was 12.6%. The 10-year mortality was 81% ± 3%. Age 65 years or more (hazard ratio [HR], 1.35; 95% confidence interval [CI], 1.03 to 1.78; P = .03), chronic obstructive pulmonary disease (HR, 1.68; 95% CI, 1.01-2.82; P = .047), and Black race (HR, 1.46; 95% CI, 1.09-1.97; P = .01) were independently associated with worse 10-year mortality. In patients with dissection, perioperative mortality was 24.3% and 10-year mortality was 87.9% ± 2.2%. Age 65 years or more (HR, 1.49; 95% CI, 1.19-1.86; P < .001), congestive heart failure (HR, 1.39; 95% CI, 1.11-2.57; P = .004), and diabetes mellitus as the cause of dialysis (HR, 1.75; 95% CI, 1.2-2.57; P = .004) were independently associated with worse 10-year mortality. Black race (HR, 0.74; 95% CI, 0.6-0.92; P = .008) was associated with a better outcome.ConclusionsWe described challenging perioperative and 10-year outcomes for dialysis patients undergoing proximal aortic repair. The present study suggests the need for careful patient selection in the elective repair of proximal aortic aneurysm for dialysis-dependent patients, whereas it affirms the feasibility of emergency surgery for acute type A aortic dissections.  相似文献

ObjectivesThe study objectives were to determine the prevalence of swallowing impairment in adults after cardiac surgery and examine associated risk factors and health-related outcomes.MethodsA prospective single-center study was conducted in postoperative adult cardiac surgery patients with no history of dysphagia. A standardized fiberoptic endoscopic evaluation of swallowing was performed within 72 hours of extubation. Blinded raters completed validated outcomes of swallowing safety and efficiency. Demographic, surgical, and postoperative health-related outcomes were collected. Univariate and multivariable regression analyses were performed with odds ratios (OR) and 95% confidence intervals (CIs).ResultsIn 182 patients examined, imaging confirmed inefficient swallowing (residue) in 52% of patients and unsafe swallowing in 94% (65% penetrators, 29% aspirators). Silent aspiration was observed in 53% of aspirators, and 32% did not clear aspirate material. Independent risk factors for aspiration included New York Heart Association III and IV (OR, 2.9; CI, 1.2-7.0); reoperation (OR, 2.0; CI, 0.7-5.5); transesophageal echocardiogram images greater than 110 (OR, 2.6; CI, 1.1-6.3); intubation greater than 27 hours (OR, 2.1; CI, 0.8-5.3); and endotracheal tube size 8.0 or greater (OR, 3.1; CI, 1.1-8.6). Patients with 3 or 4 identified risk factors had a 16.4 (CI, 3.2-148.4) and 22.4 (CI, 3.7-244.7) increased odds of aspiration, respectively. Compared with nonaspirators, aspirators waited an additional 85 hours to resume oral intake, incurred $49,372 increased costs, and experienced a 43% longer hospital stay (P < .05). Aspiration was associated with pneumonia (OR, 2.6; CI, 1.1-6.5), reintubation (OR, 5.7; CI, 2.1-14.0), and death (OR, 2.8; CI, 1.2-9.0).ConclusionsTracheal aspiration was prevalent, covert, and associated with increased morbidity and mortality.  相似文献

ObjectivesGuidelines suggest aortic valve replacement (AVR) for low-risk asymptomatic patients. Indications for transcatheter AVR now include low-risk patients, making it imperative to understand state-of-the-art surgical AVR (SAVR) in this population. Therefore, we compared SAVR outcomes in low-risk patients with those expected from Society of Thoracic Surgeons (STS) models and assessed their intermediate-term survival.MethodsFrom January 2005 to January 2017, 3493 isolated SAVRs were performed in 3474 patients with STS predicted risk of mortality <4%. Observed operative mortality and composite major morbidity or mortality were compared with STS-expected outcomes according to calendar year of surgery. Logistic regression analysis was used to identify risk factors for these outcomes. Patients were followed for time-related mortality.ResultsWith 15 observed operative deaths (0.43%) compared with 55 expected (1.6%), the observed:expected ratio was 0.27 for mortality (95% confidence interval [CI], 0.14-0.42), stroke 0.65 (95% CI, 0.41-0.89), and reoperation 0.50 (95% CI, 0.42-0.60). Major morbidity or mortality steadily declined, with probabilities of 8.6%, 6.7%, and 5.2% in 2006, 2011, and 2016, respectively, while STS-expected risk remained at approximately 12%. Mitral valve regurgitation, ventricular hypertrophy, pulmonary, renal, and hepatic failure, coronary artery disease, and earlier surgery date were residual risk factors. Survival was 98%, 91%, and 82% at 1, 5, and 9 years, respectively, superior to that predicted for the US age-race-sex–matched population.ConclusionsSTS risk models overestimate contemporary SAVR risk at a high-volume center, supporting efforts to create a more agile quality assessment program. SAVR in low-risk patients provides durable survival benefit, supporting early surgery and providing a benchmark for transcatheter AVR.  相似文献

ObjectivesExtracorporeal membrane oxygenation (ECMO) for postcardiotomy cardiogenic shock has been increasingly used without concomitant mortality reduction. This study aims to investigate determinants of in-hospital and postdischarge mortality in patients requiring postcardiotomy ECMO in the Netherlands.MethodsThe Netherlands Heart Registration collects nationwide prospective data from cardiac surgery units. Adults receiving intraoperative or postoperative ECMO included in the register from January 2013 to December 2019 were studied. Survival status was established through the national Personal Records Database. Multivariable logistic regression analyses were used to investigate determinants of in-hospital (3 models) and 12-month postdischarge mortality (4 models). Each model was developed to target specific time points during a patient's clinical course.ResultsOverall, 406 patients (67.2% men, median age, 66.0 years [interquartile range, 55.0-72.0 years]) were included. In-hospital mortality was 51.7%, with death occurring in a median of 5 days (interquartile range, 2-14 days) after surgery. Hospital survivors (n = 196) experienced considerable rates of pulmonary infections, respiratory failure, arrhythmias, and deep sternal wound infections during a hospitalization of median 29 days (interquartile range, 17-51 days). Older age (odds ratio [OR], 1.02; 95% CI, 1.0-1.04) and preoperative higher body mass index (OR, 1.08; 95% CI, 1.02-1.14) were associated with in-hospital death. Within 12 months after discharge, 35.1% of hospital survivors (n = 63) died. Postoperative renal failure (OR, 2.3; 95% CI, 1.6-4.9), respiratory failure (OR, 3.6; 95% CI, 1.3-9.9), and re-thoracotomy (OR, 2.9; 95% CI, 1.3-6.5) were associated with 12-month postdischarge mortality.ConclusionsIn-hospital and postdischarge mortality after postcardiotomy ECMO in adults remains high in the Netherlands. ECMO support in patients with higher age and body mass index, which drive associations with higher in-hospital mortality, should be carefully considered. Further observations suggest that prevention of re-thoracotomies, renal failure, and respiratory failure are targets that may improve postdischarge outcomes.  相似文献

ObjectiveTo discern the impact of depressed left ventricular ejection fraction (LVEF) on the outcomes of open descending thoracic aneurysm (DTA) and thoracoabdominal aneurysms (TAAA) repair.MethodsRestricted cubic spline analysis was used to identify a threshold of LVEF, which corresponded to an increase in operative mortality and major adverse events (MAE: operative death, myocardial infarction, stroke, spinal cord injury, need for tracheostomy or dialysis). Logistic and Cox regression were performed to identify independent predictors of MAE, operative mortality, and survival.ResultsDTA/TAAA repair was performed in 833 patients between 1997 and 2018. Restricted cubic spline analysis showed that patients with LVEF <40% (n = 66) had an increased risk of MAE (odds ratio [OR], 2.17; 95% confidence interval [CI], 1.22-3.87; P < .01) and operative mortality (OR, 2.72; 95% CI, 1.21-6.12; P = .02) compared with the group with LVEF ≥40% (n = 767). The group with LVEF <40% had a worse preoperative profile (eg, coronary revascularization, 48.5% vs 17.3% [P < .01]; valvular disease, 82.8% vs 49.39% [P < .01]; renal insufficiency, 45.5% vs 26.1% [P < .01]; respiratory insufficiency, 36.4% vs 21.2% [P = .01]) and worse long-term survival (35.5% vs 44.7% at 10 years; P = .01). Nonetheless, on multivariate regression, depressed LVEF was not an independent predictor of operative mortality, MAE, or survival.ConclusionsLVEF is not an independent predictor of adverse events in surgery for DTA.  相似文献

ObjectiveWe sought to describe characteristics and operative outcomes of children who underwent repair of truncus arteriosus and identify risk factors for the occurrence of major adverse cardiac events (MACE) in the immediate postoperative period in a contemporary multicenter cohort.MethodsWe conducted a retrospective review of children who underwent repair of truncus arteriosus between 2009 and 2016 at 15 centers within the United States. Patients with associated interrupted or obstructed aortic arch were excluded. MACE was defined as the need for postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, or operative mortality. Risk factors for MACE were identified using multivariable logistic regression analysis and reported as odds ratios (ORs) with 95% confidence intervals (CIs).ResultsWe reviewed 216 patients. MACE occurred in 44 patients (20%) and did not vary significantly over time. Twenty-two patients (10%) received postoperative extracorporeal membrane oxygenation, 26 (12%) received cardiopulmonary resuscitation, and 15 (7%) suffered operative mortality. With multivariable logistic regression analysis (which included adjustment for center effect), factors independently associated with MACE were failure to diagnose truncus arteriosus before discharge from the nursery (OR, 3.1; 95% CI, 1.3-7.4), cardiopulmonary bypass duration >150 minutes (OR, 3.5; 95% CI, 1.5-8.5), and right ventricle-to-pulmonary artery conduit diameter >50 mm/m2 (OR, 4.7; 95% CI, 2.0-11.1).ConclusionsIn a contemporary multicenter analysis, 20% of children who underwent repair of truncus arteriosus experienced MACE. Early diagnosis, shorter duration of cardiopulmonary bypass, and use of smaller diameter right ventricle-to-pulmonary artery conduits represent potentially modifiable factors that could decrease morbidity and mortality in this fragile patient population.  相似文献

ObjectivesLong-term real-world outcomes are critical for informing decisions about biological (Bio) or mechanical (Mech) prostheses for aortic valve replacement, particularly in patients aged between 50 and 65 years. The objective was to compare long-term survival and major adverse cardiac and cardiovascular events (ie, stroke, reoperation, and major bleeding) within this population.MethodsThis was a multicenter observational study including all patients aged between 50 and 65 years who underwent an aortic valve replacement because of severe isolated aortic stenosis between the years 2000 and 2018. A total of 5215 patients from 27 Spanish hospitals were registered with a follow-up of 15 years. Multivariable analyses, including a 2:1 propensity score matching (1822 Mech and 911 Bio) and competing risks analyses were applied.ResultsBio prostheses were implanted in 19% of patients (n = 992). No significant differences were observed between matched groups in long-term survival (hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.88-1.47; P = .33). Stroke rates were higher for Mech prostheses, but not significant (HR, 0.72; 95% CI, 0.50-1.03; P = .07). Finally, higher rates of major bleeding were found in the Mech group (HR, 0.65; 95% CI, 0.49-0.87; P = .004), whereas reoperation was more frequent among the Bio group (HR, 3.04; 95% CI, 1.80-5.14; P < .001). Bio prostheses increased from 13% in the period from 2000 to 2008 to 24% in 2009 to 2018.ConclusionsLong-term survival was comparable among groups in patients between 50 and 65 years of age. Mech prostheses were associated with a higher risk of major bleeding, whereas Bio prostheses entailed higher reoperation rates. Bio prostheses seem a reasonable choice for patients between 50 and 65 years in Spain.  相似文献

IntroductionThere is uncertainty surrounding the role of resection as an option for curative treatment of breast cancer with liver metastases (BCLM).AimTo perform a systematic review and meta-analysis evaluating the role of liver resection for BCLM.MethodsA systematic review was performed as per PRISMA guidelines. Hazard ratio (HR) for overall survival (OS) and standard error was obtained from each study and expressed using the generic inverse variance method, with a corresponding 95% confidence interval (CI). OS outcomes at 1- 3- and 5-years were expressed as dichotomous variables and pooled as odds ratios (OR) using the Mantel-Haenszel method.ResultsNine studies with 1732 patients were included. Of these, 24.5% underwent surgical resection of BCLM (424/1732) and 75.5% did not (1308/1732). Overall, OS was significantly better among those who underwent surgery versus controls (HR: 0.69, 95% CI: 0.59–0.80, P < 0.00001). Mortality rates were significantly reduced at 1-year (7.5% (10/134) vs 20.3% (79/390), OR: 0.25, 95% CI: 0.08–0.74, P = 0.010) and 5-years (54.0% (190/352) vs 75.3% (940/1249), OR: 0.46, 95% CI: 0.25–0.87, P = 0.020) respectively for those undergoing surgery versus controls. Mortality rates at 3 years after surgery were lower than the control group (19.1% (29/152) vs 53.0% (222/419)), however this failed to achieve statistical significance at meta-analysis (OR: 0.32, 95% CI: 0.09–1.12, P = 0.070).ConclusionLiver resection may be considered at multidisciplinary meetings for those with BCLM and offers a potentially curative option. However, judicious patient selection is crucial prior to making decisions in relation to resection of BCLM.  相似文献

ObjectiveThe effect of ventricular dominance and previous atrioventricular valve (AVV) surgery on patient outcomes after Fontan operation remains unclear. We sought to determine the effect of ventricular dominance and previous AVV surgery on transplantation-free survival and long-term AVV competency in patients with atrioventricular septal defect (AVSD) and Fontan circulation.MethodsWe conducted a retrospective study of 1703 patients in the Australia and New Zealand Fontan Registry, who survived Fontan operation between 1987 and 2021.ResultsOf 174 patients with AVSD, 60% (105/174) had right ventricular (RV) dominance and 40% (69/174) had left ventricular (LV) dominance. The cumulative incidence of moderate or greater AVV regurgitation at 25 years after Fontan operation in patients with LV dominance was 56% (95% CI, 35%-72%), compared with 54% (95% CI, 40%-67%) in patients with RV dominance (P = .6). Nonetheless, transplantation-free survival at 25 years in patients with LV dominance was 94% (95% CI, 86%-100%), compared with 67% (95% CI, 52%-87%) in patients with RV dominance (hazard ratio, 5.9; 95% CI, 1.4-25.4; P < .01). Of note, transplantation-free survival was not different in patients who underwent AVV surgery before or at Fontan completion compared with those who did not (15 years: 81% [95% CI, 62%-100%] vs 88% [95% CI, 81%-95%]; P = .3).ConclusionsIn patients with AVSD and Fontan circulation the rate of moderate or greater common AVV regurgitation is similar in those with LV and RV dominance. RV dominance, rather than previous AVV surgery, is a risk factor for death or transplantation.  相似文献

PurposeThe study aimed to introduce anterior superior iliac spine distraction to treat severe and recalcitrant diabetic foot ulcers. For comparison, we also included another group of diabetic foot ulcers treated with proximal tibial cortex transverse distraction.MethodsFrom February 1998 to February 2020, 87 patients (87 feet) with severe and recalcitrant diabetic foot ulcers were treated. The mean age of patients at surgery was 64 years (range, 47 to 87 years). The severity of the narrowed artery was assessed using the ankle-brachial index test. For comparison, another group of 91 patients (91 diabetic foot ulcers) treated with proximal tibial cortex transverse distraction was included.ResultsThe mean preoperative ankle-brachial indexes of the two groups were 0.41±0.07 and 0.39±0.05 (OR 0.65 [95% CI -0.77 to 1.58]; P=0.62), respectively. The mean preoperative limb pain was 3.42±2.84 cm and 3.52±3.11 cm (OR 1.54 [95% CI -077 to 1.35]; P=0.083), respectively. At the 2-year follow-up visit, ulcers healed in 72 (83%) and 74 (81%) patients, respectively (P=0.188). The mean postoperative limb pain was 0.52±0.23 cm and 0.49±0.41 cm (OR 2.32 [95% CI -0.27 to 1.66]; P=0.078), respectively. Pin-site infection occurred in 2 patients and 8 patients (P=0.09), respectively. Ulcer recurrence occurred in 13 (15%) patients and 15 (16%) patients (P=0.205), respectively.ConclusionsAnterior superior iliac spine transverse distraction may be an effective alternative treatment for severe and recalcitrant diabetic foot ulcers. It may be associated with fewer distraction-site complications than proximal tibial cortex transverse distraction.Level of evidenceTherapeutic study, Level IIa.  相似文献

Study objectiveTo determine the effect of cognitive impairment (CI) and dementia on adverse outcomes in older surgical patients.DesignA systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs). Various databases were searched from their inception dates to March 8, 2021.SettingPreoperative assessment.PatientsOlder patients (≥ 60 years) undergoing non-cardiac surgery.MeasurementsOutcomes included postoperative delirium, mortality, discharge to assisted care, 30-day readmissions, postoperative complications, and length of hospital stay. Effect sizes were calculated as Odds Ratio (OR) and Mean Difference (MD) based on random effect model analysis. The quality of included studies was assessed using the Cochrane Risk Bias Tool for RCTs and Newcastle-Ottawa Scale for observational cohort studies.ResultsFifty-three studies (196,491 patients) were included. Preoperative CI was associated with a significant risk of delirium in older patients after non-cardiac surgery (25.1% vs. 10.3%; OR: 3.84; 95%CI: 2.35, 6.26; I2: 76%; p < 0.00001). Cognitive impairment (26.2% vs. 13.2%; OR: 2.28; 95%CI: 1.39, 3.74; I2: 73%; p = 0.001) and dementia (41.6% vs. 25.5%; OR: 1.96; 95%CI: 1.34, 2.88; I2: 99%; p = 0.0006) significantly increased risk for 1-year mortality. In patients with CI, there was an increased risk of discharge to assisted care (44.7% vs. 38.3%; OR 1.74; 95%CI: 1.05, 2.89, p = 0.03), 30-day readmissions (14.3% vs. 10.8%; OR: 1.36; 95%CI: 1.00, 1.84, p = 0.05), and postoperative complications (40.7% vs. 18.8%; OR: 1.85; 95%CI: 1.37, 2.49; p < 0.0001).ConclusionsPreoperative CI in older surgical patients significantly increases risk of delirium, 1-year mortality, discharge to assisted care, 30-day readmission, and postoperative complications. Dementia increases the risk of 1-year mortality. Cognitive screening in the preoperative assessment for older surgical patients may be helpful for risk stratification so that appropriate management can be implemented to mitigate adverse postoperative outcomes.  相似文献

ObjectiveTo report long-term outcomes after deep hypothermic circulatory arrest (DHCA) with or without perioperative blood or blood products.MethodsAll patients who underwent proximal aortic surgery with DHCA from 2011 to 2018 were propensity matched according to baseline characteristics. Primary outcomes included short- and long-term mortality. Stratified Cox regression analysis was performed for significant associations with survival.ResultsA total of 824 patients underwent aortic replacement requiring circulatory arrest. After matching, there were 224 patients in each arm (transfusion and no transfusion). All baseline characteristics were well matched, with a standardized mean difference (SMD) <0.1. Preoperative hematocrit (41.0 vs 40.6; SMD = 0.05) and ejection fraction (57.5% vs 57.0%; SMD = 0.08) were similar between the no transfusion and blood product transfusion cohorts. Rate of aortic dissection (42.9% vs 45.1%; SMD = 0.05), hemiarch replacement (70.1% vs 70.1%; SMD = 0.00), and total arch replacement (21.9% vs 23.2%; SMD = 0.03) were not statistically different. Cardiopulmonary bypass and cross-clamp time were higher in the blood product transfusion cohort (P < .001). Operative mortality (9.4% vs 2.7%; P = .003), stroke (7.6% vs 1.3%; P = .001), reoperation rate, pneumonia, prolonged ventilation, and dialysis requirements were significantly higher in the transfusion cohort (P < .001). In stratified Cox regression, transfusion was an independent predictor of mortality (hazard ratio, 2.62 [confidence interval, 1.47-4.67]; P = .001). One- and 5-year survival were significantly reduced for the transfusion cohort (P < .001).ConclusionsIn patients who underwent aortic surgery with DHCA, perioperative transfusions were associated with poor outcomes despite matching for preoperative baseline characteristics.  相似文献

ObjectivesThe aim of this study was to investigate the adequacy of bronchial sleeve lobectomy by video-assisted thoracoscopic surgery in perioperative outcomes and its oncological efficacy by comparing with thoracotomy in a balanced population.MethodsA total of 363 patients who received bronchial sleeve lobectomy for non–small cell lung cancer from January 2013 to December 2017 were included and placed in the thoracotomy (n = 251) and video-assisted thoracoscopic surgery (n = 112) groups. Statistical analyses were performed to compare patients' demographics, perioperative outcomes, and survival between the 2 groups.ResultsA total of 116 thoracotomy cases were matched with 72 video-assisted thoracoscopic surgery cases by propensity score. Compared with thoracotomy, patients in the video-assisted thoracoscopic surgery group after matching had less intraoperative blood loss (P < .01) and length of postoperative hospital stay (P < .01), duration of chest tube drainage (P < .01), and intensive care unit stay (P = .03) despite comparable operative time, complication rate, and 30- to 90-day mortality rate. The overall survival and recurrence-free survival were similar in patients who received sleeve lobectomy by thoracotomy and video-assisted thoracoscopic surgery (log-rank, P = .24 and .20, respectively) at 3 years. Although advanced TNM stage was independently associated with worse overall survival and recurrence-free survival in multivariable analysis, older age was only predictive for worse overall survival (hazard ratio, 1.04; 95% confidence interval, 1.01-1.07; P = .02). Body mass index was also found be a predictive factor (overall survival: hazard ratio, 0.93; 95% confidence interval, 0.86-0.99, P = .03; recurrence-free survival: hazard ratio, 0.93; 95% confidence interval, 0.87-0.99, P = .02).ConclusionsWith appropriate patient selection and continued experience, video-assisted thoracoscopic surgery appears to be safe in the short-term perioperative period and does not appear to comprise oncologic outcomes in performing sleeve lobectomy.  相似文献

ObjectivesThe effectiveness of a multidisciplinary heart team in the management of patients with severe symptomatic aortic stenosis is unknown. This study evaluated the impact of a heart team on the outcomes of surgical aortic valve replacement in octogenarians.MethodsBetween May 2007 and January 2016, 528 patients aged 80 years or more were referred to our institutional heart team for a transcatheter aortic valve replacement. Among these, 101 were redirected to surgical aortic valve replacement (heart team group). These patients were compared with a surgical aortic valve replacement cohort (n = 506) without prior heart team screening (non-heart team group), taken from the same time period. Propensity score matching with bootstrap analysis was performed; 76 heart team patients were matched to 76 non-heart team patients. Early and late outcomes including survival and readmission for cardiovascular causes were compared.ResultsMatched subgroups were largely comparable; congestive heart failure and echocardiographic pulmonary hypertension were more prevalent in the heart team group. In-hospital mortality was significantly lower in the matched heart team group (0% vs 6.0%, bootstrap mean difference 6.0%, 95% confidence interval, 2.2-9.8). The risk of stroke, low cardiac output state, reexploration for bleeding, pneumonia, and prolonged ventilation was also significantly lower in the heart team group. There was no significant between-group difference regarding late survival (hazard ratio, 0.86, 95% confidence interval, 0.55-1.33, P = .49) or readmission for cardiovascular reasons (hazard ratio, 0.70, 95% confidence interval, 0.41-1.20, P = .19).ConclusionsPreoperative multidisciplinary assessment of octogenarians by a heart team was associated with lower in-hospital mortality and adverse events after surgical aortic valve replacement.  相似文献

BackgroundProsthetic choice for mitral valve replacement is generally driven by patient age and patient and surgeon preference, and current guidelines do not discriminate between different etiologies of mitral valve disease. Our objective was to assess and compare short- and long-term outcomes after mitral valve replacement among patients with biological or mechanical prostheses in the setting of severe ischemic mitral regurgitation.MethodsBetween 2000 and 2016, 424 patients underwent mitral valve replacement for severe ischemic mitral regurgitation at our institution, using biological prosthesis in 188 (44%) and mechanical prosthesis in 236 (56%). A 1:1 propensity score match (n = 126 per group) and inverse probability of treatment weighting were used to compare groups. Short-term outcomes included in-hospital mortality and other cardiovascular adverse events. Long-term outcomes included survival and hospital readmission for cardiovascular causes, stroke, and major bleeding.ResultsIn-hospital mortality and early postoperative adverse events were similar between groups in the propensity score match and inverse probability of treatment weighting cohorts. Overall long-term survival was similar at 5 and 9 years, but mechanical prosthesis recipients were more frequently readmitted to hospital for cardiovascular causes, including stroke and non-neurological bleeding in propensity score matching and inverse probability of treatment weighting analyses (all P values < .004). Type of prosthesis did not independently influence all-cause mortality (hazard ratio, 1.01; 95% confidence interval, 0.71-1.43; P = .959), but placement of a mechanical prosthesis was associated with increased risk of readmission for cardiovascular events (hazard ratio, 1.65; 95% confidence interval, 1.17-2.32; P = .004) among matched patients.ConclusionsThe type of prosthesis has no influence on long-term survival among patients with severe ischemic mitral regurgitation undergoing mitral valve replacement. There may be an increased risk of neurologic events and serious bleeding associated with mechanical prostheses.  相似文献
