ObjectiveTo investigate the effect of variable tricuspid annular reduction (TAR) on functional tricuspid regurgitation (FTR) and right ventricular (RV) dynamics in ovine tachycardia-induced cardiomyopathy.MethodsNine adult sheep underwent implantation of a pacemaker with an epicardial lead and were paced at 200 to 240 bpm until the development of biventricular dysfunction and functional TR was noted. During reoperation on cardiopulmonary bypass, 6 sonomicrometry crystals were placed around the tricuspid annulus (TA) and 14 were placed on the RV epicardium. Annuloplasty suture was placed around the TA and externalized to an epicardial tourniquet. After weaning from cardiopulmonary bypass, echocardiographic, hemodynamic, and sonomicrometry data were acquired at baseline and during 5 progressive TARs achieved with suture cinching. TA area and RV free wall strains and function were calculated from crystal coordinates.ResultsAfter pacing, changes in left ventricular (LV) ejection fraction and RV fractional area decreased significantly. Mean TA diameter increased from 25.1 ± 2.9 mm to 31.5 ± 3.3 mm (P = .005), and median TR (range, 0-3+) increased from 0 (0) to 3 (2) (P = .004). Progressive suture cinching reduced the TA area by 18 ± 6%, 38 ± 11%, 56 ± 10%, 67 ± 9%, and 76 ± 8%. Only aggressive annular reductions (67% and 76%) decreased TR significantly, but these were associated with deterioration of RV function and strain. A moderate annular reduction of 56% led to a substantial reduction of TR with little deleterious effect on regional RV function.ConclusionsA moderate TAR of approximately 50% may be most advantageous for correction of functional TR and simultaneous maintenance of regional RV performance. Additional subvalvular interventions may be needed to achieve complete valvular competence. 相似文献

ObjectivesMinisternotomy and right anterior minithoracotomy are the 2 main techniques applied for minimally invasive aortic valve replacement. The goal of this study is to compare early and long-term outcomes of both techniques.MethodsThe data of 2419 patients undergoing isolated minimally invasive aortic valve replacement between 1999 and 2019 were prospectively collected. Retrospectively, patients were divided into the ministernotomy group (n = 1352) and the minithoracotomy group (n = 1067).ResultsAfter propensity score matching, 986 patients remained in each group. Operation time and rate of conversion to full sternotomy were significantly higher in the minithoracotomy group than in the ministernotomy group (184.6 ± 45.2 vs 241.3 ± 68.6, relative risk, 2.54, P = .005 and .09 vs .23, relative risk, 1.45, P = .013, respectively). The 30-day mortality, excluding cardiac death, was lower in the ministernotomy group than in the minithoracotomy group (0.012 vs 0.028, relative risk, 1.41, P = .011, respectively); the intensive care unit length of stay (12.4 vs 16.5, relative risk, 1.62, P = .037, respectively) and hospital length of stay (5.4 vs 8.7, relative risk, 1.74 P = .028, respectively) were significantly longer in the minithoracotomy group. The minithoracotomy surgical approach was the strongest independent predictor of early mortality (odds ratio, 4.24 [1.67-7.35], P = .002). The actuarial survival by Kaplan–Meier analysis at 1, 3, 5, 10, and 20 years was significantly better in the ministernotomy group than in the minithoracotomy group (P = .0001). Actuarial freedom from reoperation at 5 years was 97.3% ± 4.4% in the ministernotomy group versus 95.8% ± 5.2% in the minithoracotomy group (P = .087).ConclusionsMinimally invasive aortic valve replacement using ministernotomy is associated with reduced operative time, intensive care unit stay, hospital length of stay, and postoperative morbidities and incisional pain, and improves early and long-term mortality. 相似文献

PurposeThe purpose of this study was to evaluate the effectiveness of computed tomography (CT)-guided infiltration of greater occipital nerve (GON) for the treatment of refractory craniofacial pain syndromes other than occipital neuralgia.Materials and methodsFifty-six patients suffering from refractory craniofacial pain syndromes were included between 2011 and 2017. There were 33 women and 23 men with a mean age of 50.7 years ± 13.1 (SD) (range: 27–74 years). CT-guided infiltration was performed at the intermediate site of the GON with local anesthetics and cortivazol. Twenty-six (26/56; 46%) patients suffered from chronic migraine, 14 (14/56; 25%) from trigeminal neuralgia and 16 (16/56; 29%) from cluster headaches. Clinical success at 1, 3, and 6 months was defined by a decrease of at least 50% of pain as assessed using visual analog scale (VAS).ResultsMean overall VAS score before infiltration was 8.7 ± 1.3 (SD) (range: 6 - 10). Mean overall VAS scores after infiltration were 2.3 ± 3 (SD) (range: 0 - 10) (P < 0.01) at one month, 3.5 ± 3.3 (SD) (range: 0 - 10) (P < 0.01) at three months and 7.6 ± 1.3 (SD) (range: 1–10) (P < 0.01) at six months. After infiltration, clinical success was achieved in 44 patients (44/56; 78.5%) at 1 month, 37 patients (37/56; 66%) at 3 months and 13 patients (13/56; 23%) at 6 months. Clinical success according to the clinical presentation were as follows: 88% (23/26) at one month, 73% (19/26) at 3 months, and 23% (6/26) at 6 months in patients with chronic migraine, 81% (13/16), 69% (11/16) and 31% (5/16) in those with cluster headaches and 57% (8/14), 50% (7/14) and 14% (2/14) in those with trigeminal neuralgia. No major complications due to CT-guided GON infiltration were reported in any patient.ConclusionCT-guided infiltration at the intermediate site of the GON appears as an effective treatment of craniofacial pain syndromes especially in patients with chronic migraine and those with cluster headaches. 相似文献

BackgroundPVI has been shown to be an accurate predictor of fluid responsiveness in paediatric patients. Evidence regarding the role of PVI to guide intraoperative fluid therapy in paediatric abdominal surgery is lacking. We aimed to assess the effect of PVI-guided fluid therapy on the volume of intraoperative fluids administered and post-operative biochemical and recovery profile in children undergoing elective abdominal surgery.Methods42 children, 6 months-3 years scheduled for elective open bowel surgery were randomised to receive either ‘conventional liberal intraoperative fluids’ (liberal group) or ‘goal-directed intraoperative fluids’ (GDT group). PVI <13 was targeted in the GDT group. The primary outcome was the volume of intraoperative fluids administered. Postoperative serum lactate, base excess, hematocrit, recovery of bowel function and duration of postoperative hospital stay were the secondary outcomes.ResultsThe mean fluid administered intra-operatively was significantly lower in the GDT group as compared to the liberal group (24.1 ± 9.6 mL/kg vs 37.0 ± 8.9 mL/kg, p < 0.001). The postoperative hemoglobin concentration (g%) was significantly lower in the liberal group as compared to the GDT group (8.1 ± 1.3 vs 9.2 ± 1.4, p = 0.008). Recovery of bowel function (hours) was significantly delayed in the liberal group as compared to the GDT group (58.2 ± 17.9 vs 36.5 ± 14.1, p < 0.001).ConclusionIntraoperative PVI-guided fluid therapy significantly reduces the volume of intravenous crystalloids administered to children undergoing open bowel surgery. These children also had faster recovery of bowel function and less hemodilution in the immediate postoperative period, compared to those who received liberal intraoperative fluid therapy.Type of study: Randomized Clinical Trial.Level of evidence: Treatment Study (LEVEL 1). 相似文献

IntroductionTHA (Total hip arthroplasty) in advanced grade (grade 4) avascular necrosis (AVN) is a challenge to the treating surgeon as it affects young patients who have high functional demands and increased dislocation risk. The aim of the study was to evaluate the efficacy, survivorship, and dislocation rate of uncemented dual mobility cups (DMC) in advanced grade IV AVN young patients.MethodsRetrospective cohort study involving 204 DMC THA for advanced grade IV AVN from January 2013 to December 2015. The sample size of the study was estimated to be 188 hips with an α error of 0.05 and β error of 0.2. Inclusion criterion was patients less than 55 years of age with advanced grade IV AVN. Patients >55 years of age, patients diagnosed with primary osteoarthritis of the hip and hip fracture were excluded from the study. 172 patients (32 with bilateral & 140 with unilateral affection) with 204 DMC THA were evaluated clinically by Harris Hip Score (HHS) and radiologically at a follow up of 60 months. P value < 0.05 was considered significant.ResultsMean age of the patients was 42.5 ± 5.3. Preoperative HHS was 50.6 ± 10.5. Postoperative HHS at 5 years follow up was 96.4 ± 2.6. None of the operated patient had any dislocation episode or had undergone hip revision surgery (statistically significant against historical control of 2%, p value = 0.042). The radiological evaluation at 5 years showed no signs of radiolucent lines, periprosthetic osteolysis, polyethylene wear and signs of displacement or migration of the DMC. Cumulative survivorship rate at 5 years follow up was 100% without any revision/dislocation.ConclusionUse of DMC THA in young, advanced grade IV AVN patients was found to be a reliable option showing excellent early functional results with no dislocation. Ongoing follow up of this cohort is required to confirm the maintenance of these excellent functional results at follow up in the long term. 相似文献

BackgroundWhile clinical findings demonstrate a superior benefit of cardiovascular (CV) risk reduction in obese patients with type 2 diabetes mellitus (T2D) receiving bariatric surgery over non-T2D patients, the mechanism is unclear. This study aimed to investigate the changes in the CV risk score and five CV-associated biomarkers after gastric bypass surgery.MethodWe enrolled 80 obese subjects who underwent gastric bypass (40 T2D and 40 non-T2D). CV risks were assessed using the United Kingdom Prospective Diabetes Study (UKPDS) engine before and after surgery. Levels of five biomarkers —fasting serum fibroblast growth factor (FGF)-19, FGF-21, corin, oxidized low-density lipoprotein (ox-LDL), and soluble receptor for advanced glycation end-products (sRAGE)—were measured before surgery and one year after surgery.ResultsThe T2D group was significantly older and had a higher CV risk score than the non-T2D group, but body mass index (BMI) was similar between the groups. Preoperative biomarker levels were similar in both the T2D and the non-T2D groups. One year after surgery, the percentage of total weight loss (%TWL) was similar between the two groups (32.2 ± 19.5% versus 34.1% ± 8.8%, p = 0.611). Complete T2D remission (hemoglobin A1c (HbA1c) < 6.0%) was achieved in 29 patients (72.5%). The 10-year CV risk scores by the UKPDS risk engine reduced significantly in both the T2D and the non-T2D groups, but more in the T2D group. Three of five biomarkers changed significantly after surgery: the FGF-19 increased from 195.6 ± 249.1 pg/mL to 283.2 ± 211.8 pg/mL, corin increased from 3.3 ± 2.3 ng/mL to 4.6 ± 3.7 ng/mL, and ox-LDL decreased from 148.5 ± 71.7–107.9 U/L; the P values were 0.002, 0.002 and < 0.001, respectively. The T2D group showed a significantly different change in FGF-19 increase and FGF-21 decrease compared to the non-T2D group. The changes in corin and ox-LDL levels were not different between the T2D and non-T2D groups.ConclusionGastric bypass surgery resulted in a higher UKPDS CV risk score reduction in obese T2D Asians than in those without. FGF-19 and FGF-21 may be associated with the underlying mechanism of this difference. 相似文献

Study objectiveWe explored the feasibility of a Clinical Decision Support System (CDSS) to guide evidence-based perioperative anticoagulation.DesignProspective randomised clinical management simulation multicentre study.SettingFive University and 11 general hospitals in Germany.ParticipantsWe enrolled physicians (anaesthesiologist (n = 73), trauma surgeons (n = 2), unknown (n = 1)) with different professional experience.InterventionsA CDSS based on a multiple-choice test was developed and validated at the University Hospital of Frankfurt (phase-I). The CDSS comprised European guidelines for the management of anticoagulation in cardiology, cardio-thoracic, non-cardio-thoracic surgery and anaesthesiology. Phase-II compared the efficiency of physicians in identifying evidence-based approach of managing perioperative anticoagulation. In total 168 physicians were randomised to CDSS (PERI-KOAG) or CONTROL.MeasurementsOverall mean score and association of processing time and professional experience were analysed. The multiple-choice test consists of 11 cases and two correct answers per question were required to gain 100% success rate (=22 points).Main resultsIn total 76 physicians completed the questionnaire (n = 42 PERI-KOAG; n = 34 CONTROL; attrition rate 54%). Overall mean score (max. 100% = 22 points) was significantly higher in PERI-KOAG compared to CONTROL (82 ± 15% vs. 70 ± 10%; 18 ± 3 vs. 15 ± 2 points; P = 0.0003). A longer processing time is associated with significantly increased overall mean scores in PERI-KOAG (≥33 min. 89 ± 10% (20 ± 2 points) vs. <33 min. 73 ± 15% (16 ± 3 points), P = 0.0005) but not in CONTROL (≥33 min. 74 ± 13% (16 ± 3 points) vs. <33 min. 69 ± 9% (15 ± 2 points), P = 0.11). Within PERI-KOAG, there is a tendency towards higher results within the more experienced group (>5 years), but no significant difference to less (≤5 years) experienced colleagues (87 ± 10% (19 ± 2 points) vs. 78 ± 17% (17 ± 4 points), P = 0.08). However, an association between professional experience and success rate in CONTROL has not been shown (71 ± 8% vs. 70 ± 13%, 16 ± 2 vs. 15 ± 3 points; P = 0.66).ConclusionsCDSS significantly improved the identification of evidence-based treatment approaches. A precise usage of CDSS is mandatory to maximise efficiency. 相似文献

BackgroundSurgical repair of functional tricuspid regurgitation is centered on annular reduction with artificial rings; however, the precise effect of prosthesis implantation on annular geometry, dynamics, and strain is unknown.MethodsForty healthy sheep had sonomicrometry crystals implanted around the tricuspid annulus and onto right ventricle free wall. Ten animals underwent tricuspid annuloplasty with a flexible Duran AnCore ring (Medtronic, Minneapolis, Minn) (28 ± 1 mm), 10 with Contour 3D rigid ring (Medtronic) (29 ± 1 mm), 10 with hybrid Tri-Ad Adams band (Medtronic) (28 ± 1 mm), and 10 had no prosthesis (control group). Pressure sensors were inserted in the left ventricle, right ventricle, and right atrium. Data were acquired with open chest after weaning off cardiopulmonary bypass and hemodynamic stabilization. Annular area, global and regional contraction, height, and strain were calculated based on cubic spline fits to crystal locations.ResultsTricuspid annular area contraction during the cardiac cycle was 11% ± 3% in the control group. The Contour 3D ring significantly impaired annular contraction (2% ± 1%) whereas the Duran AnCore ring and Tri-Ad Adams band (9% ± 3% and 8% ± 4%, respectively) permitted dynamic area change. Global perimeter reduction was 6% ± 1% in the control group and decreased in the Duran AnCore (3% ± 1%), Contour 3D (0.4% ± 0.2%), and Tri-Ad Adams (3% ± 1%) groups (all P values < .001 vs control). Annular height was 6.2 ± 2.0 mm in the control group, unchanged in the Contour 3D (4.9 ± 1.1 mm) but reduced in the Duran AnCore (3.1 ± 1.3 mm) and Tri-Ad Adams (3.1 ± 1.0 mm) groups (P < .001 Duran AnCore and Tri-Ad Adams vs control). Rings perturbed systolic global annular strain (control, 5.3% ± 1.8%; Duran AnCore, 2.3% ± 1.0%; Contour 3D, 0.6% ± 0.2%; and Tri-Ad Adams, –2.6% ± 0.7%) with Contour 3D inducing the biggest change (P < .05 vs other groups).ConclusionsIn healthy ovine hearts, flexible and hybrid rings better preserved annular dynamics and strain, whereas the rigid ring maintained 3-dimensional geometry. These data may aid the design of optimal tricuspid annular prostheses and improve durability of valve repair. 相似文献

AimRetroperitoneal pyeloplasty (RP) for pediatric ureteropelvic junction obstruction (UPJO) performed using retroperitoneoscopy (retro-RP) or robotic assistance (robo-RP) were compared.MethodsAll subjects were Japanese, matched for age, weight, and RP diameters. All RP were performed in the lateral decubitus position at a single institute by the same team using identical protocols. Five independent surgeons were asked to score intraoperative video recordings for perceived difficulty of suturing (DOS; 5 = impossible; 4 = difficult; 3 = tedious; 2 = slow; 1 = easy) and rank RP as +1 if robo-RP appeared to be superior, 0 if they appeared to be the same, and −1 if robo-RP appeared to be inferior.ResultsRobo-RP performed 2018-2022 (n = 22) were matched with retro-RP performed 2011-2019 (n = 34). Mean overall operative times were similar (robo-RP: 305.2 ± 57.8 min versus retro-RP: 340.0 ± 117.9 min; p = 0.19), but securing the larger retroperitoneal space required for robo-RP took significantly longer; 50.8 ± 13.9 min versus 24.3 ± 9.6 min; p < 0.0001. Total anastomotic time (TAT) and TAT per suture were both significantly shorter for robo-RP (p < 0.0001). The coefficient of variation for time taken to place one suture was smaller for robo-RP than for retro-RP. DOS was lower for robo-RP with less variance (p < 0.01). Robo-RP had shorter drainage tube insertion, ambulated quicker postoperatively, and shorter hospitalization. Retro-RP had anastomotic complications; leaks (n = 2) and strictures (n = 2, requiring conventional open re-pyeloplasty). Robo-RP had no anastomotic complications and was ranked +1 unanimously.ConclusionsThe RP anastomosis was quicker with less complications and more precise with robotic assistance in matched patients under similar circumstances. Should RP be indicated, robo-RP is recommended.Level of evidenceIII. 相似文献

ObjectiveMinimally invasive direct coronary artery bypass (MIDCAB) surgery involving left anterior descending coronary artery grafting with the left internal thoracic artery through a left anterior small thoracotomy is being routinely performed in some specified centers for patients with isolated complex left anterior descending coronary artery disease, but very few reports regarding long-term outcomes exist in literature. Our study was aimed at assessing and analyzing the early and long-term outcomes of a large cohort of patients who underwent MIDCAB procedures and identifying the effects of changing trends in patient characteristics on early mortality.MethodsA total of 2667 patients, who underwent MIDCAB procedures between 1996 and 2018, were divided into 3 groups on the basis of the year of surgery: group A, 1996-2003 (n = 1333); group B, 2004-2010 (n = 627) and group C, 2011-2018 (n = 707). Groupwise characteristics and early postoperative outcomes were compared. Long-term survival for all patients was analyzed and predictors for late mortality were identified using Cox proportional hazards methods.ResultsThe mean age was 64.5 ± 10.9 years and 691 (25.9%) patients were female. Group C patients (log EuroSCORE I = 4.9 ± 6.9) were older with more cardiac risk factors and comorbidities than groups A (log EuroSCORE I = 3.1 ± 4.5) and B (log EuroSCORE I = 3.5 ± 4.7). Overall and groupwise in-hospital mortality was 0.9%, 1.0%, 0.6%, and 1.0% (P = .7), respectively. Overall 10-, 15-, and 20-year survival estimates for all patients were 77.7 ± 0.9%, 66.1 ± 1.2%, and 55.6 ± 1.6%, respectively.ConclusionsMIDCAB can be safely performed with very good early and long-term outcomes. In-hospital mortality remained constant over the 22-year period of the study despite worsening demographic profile of patients. 相似文献

PurposeThe purpose of this study was to evaluate the effectiveness and complication rate of computed tomography (CT)-guided epidural injection of steroids and local anesthetics for pain relief in patients with neuralgia due to acute or chronic herpes zoster (HZ).Materials and methodsA prospective study was conducted from April 2017 to February 2019 including patients with HZ neuralgia (HZN) at any stage (acute or chronic, the latter being defined as pain lasting more than 3 months and also called post herpetic neuralgia [PHN]). The sensory ganglion of the affected dermatome and/or the affected sensory nerve was targeted under CT-guidance and local injection of a mixture of two vials of methylprednisolone 40 mg/mL and 2 mL of Lidocaine 1% was performed. Using a visual analogue scale (VAS, 0 to 10), pain was assessed prior to the procedure, and at day 7, 1 month, 3 months and 6 months. Adverse effects were graded according to the Society of Interventional Radiology classification.ResultsTwenty patients were included. There were 9 men and 11 women with a mean age of 67 ± 13.9 (SD) years (range: 27–83 years). Of these, 14 patients had acute HZN and 6 had PHN. Mean VAS at baseline was 8.1 ± 1.2 (SD) (range: 6–10) with significant decrease (P < 0.0001) at day 7 (3.4 ± 3.2 [SD]; range: 0–10), day 30 (3.4 ± 3.2 [SD]; range: 0–9), day 90 (2.9 ± 3.2 [SD]; range: 0–9), and day 180 (2.5 ± 3.1 [SD]; range: 0–9). Infiltrations were significantly more effective on acute HZN than on PHN (P < 0.001) and required significantly fewer infiltrations for pain relef (P = 0.002). Only one grade A adverse event was reported.ConclusionEpidural injection of a mixture of steroids and local anesthetics under CT-guidance is effective on HZN with a persisting effect over 6 months. 相似文献

BackgroundA delay in the diagnosis and treatment of an occult femoral neck fracture (OFNF) can negatively affect the subsequent quality of life. We investigated the diagnostic accuracy of ultrasonography for OFNF in patients confirmed with this condition by magnetic resonance imaging (MRI), and compared these results with other clinical findings.MethodsNinety-four outpatients aged above 70 years with acute hip pain but without radiographic abnormal findings who were suspected of having an occult femoral neck fracture (11 men and 83 women with a mean age of 81.8 ± 6.0 years) were enrolled. Both ultrasonography and MRI were performed in all cases within 24 h. The ultrasonographic distance between the anterior aspect of the femoral neck and the anterior joint capsule (ultrasound joint swelling) was measured.ResultsBy MRI findings, 27 patients were assigned to an occult femoral neck fracture (OFNF) group (1 man, 26 women) and 67 patients to a non-OFNF group (10 men, 57 women). The mean ultrasound joint swelling in both groups was 7.53 ± 1.52 mm and 3.45 ± 0.89 mm, respectively (p = 0.006, 95% CI, 3.58–4.59). A cut-off value of 5.3 mm showed a sensitivity of 0.96 (0.89–0.96) and a specificity of 0.98 (0.92–1.00).ConclusionsUltrasonography shows very high diagnostic accuracy for occult femoral neck fracture. This modality can thus contribute to initial bed-side examinations for this condition in patients over 70 years with acute hip pain. 相似文献

BackgroundThis study aims to describe the outcomes after heart transplantation using a bridge-to-bridge strategy with a sequence of extracorporeal membrane oxygenation (ECMO) support followed by temporary total artificial heart implantation (TAH-t).MethodsA retrospective, multicenter analysis of 54 patients who underwent TAH-t implantation following an ECMO for cardiogenic shock was performed (ECMO-TAH-t group). A control group of 163 patients who underwent TAH-t implantation as a direct bridge to transplantation (TAH-t group) was used to assess this strategy's impact on outcomes.ResultsFifty-four patients, averaging 47 ± 13 year old, underwent implantation of a TAH-t after 5.3 ± 3.4 days of ECMO perfusion for cardiogenic shock. In the ECMO-TAH-t group, 20 patients (20/54%; 37%) died after TAH-t implantation and 57 patients (57/163%; 35%) died in the TAH-t group (Gray test; P = .49). The top 3 causes of death of patients on TAH-t support were multisystem organ failure (40%), sepsis (20%), and neurologic events (20%). Overall, 32 patients (32/54%; 59%) underwent heart transplantation in the ECMO-TAH-t group compared with 106 patients (106/163%, 65%) in the TAH-t group (P = .44). No significant difference in survival was observed at 6 months, 1 year, and 3 years after heart transplant (ECMO-TAH-t group: 94%, 87%, and 80% vs 87%, 83%, and 76% in the TAH-t group, respectively). Deterioration of liver function (bilirubin, aspartate transaminase, and alanine aminotransferase levels on TAH-t) was associated with increased mortality before heart transplant in both groups.ConclusionsSequential bridging from ECMO to TAH-t followed by heart transplantation is a viable option for a group of highly selected patients. 相似文献

BackgroundThe anatomical relations between the neck skin crease and the thyroid gland isthmus and cricoid cartilage are important for surgical planning.MethodsBetween 2016 and 2018 anatomical measurements were performed on 118 participants during a presurgical ultrasound exam and were verified during surgery. The data were stratified according to age, sex, patient's body mass index (BMI), and height.FindingsThe cricoid cartilage was found to be lower than the second skin neck crease by 0.2 ± 0.9 cm on average and the thyroid isthmus lower by 0.9 ± 1 cm from the second neck crease. No correlation was found to subjects' age, BMI, or height. Patient satisfaction, measured by the dermatologic life quality index, was high.ConclusionsA surgical incision made along the second neck crease will allow for a predicted and proper exposure in thyroid surgeries. The possibility of concealing the surgical scar in the natural neck skin crease can increase patients' aesthetic satisfaction. 相似文献

ObjectiveThe aim of the study was to assess mutual associations of body image perception, compliance with the prosthesis and cognitive performance in transfemoral amputees.MethodsFourty transfemoral amputee (30 male and 10 female), who had a traumatic and unilateral amputation were included in this study. The mean age of the patients at the time of study was 37 ± 9.9 and the mean age at amputation was 12.6 ± 9.4 years. Patients's body image perception and compliance with the prosthesis paramaters were evaluated with Amputee Body Image Scale (ABIS) and Trinity Amputation and Prosthesis Experience Scales (TAPES). MoCA (The Montreal Cognitive Assessment) has been used to determine the cognitive ability of the participant. All tests has been administered by dual task method during ambulation. Patients who had neurologic or cognitive deficit were excluded from the study.ResultsThere was a statistically significant relationship between an individual's body image perception and cognitive performance. Body image perception was significantly and negatively correlated with the MoCA score (r = −0.514, p < 0.001). There was a statistically significant positive correlation between psychosocial adjustment, prosthesis satisfaction and MoCA scores (r = 0.550, p < 0.001).ConclusionsBody image satisfaction, psychosocial adjustment, lack of activity restriction, and satisfaction with prosthesis are positively associated with cognitive performance of transfemoral amputees. Before beginning the amputee rehabilitation programs, we recommend to include not only physical functions, but also consider body image and cognitive functions as assessment parameters.Level of evidenceLevel IV, Diagnostic Study. 相似文献

IntroductionCongenital anomalies necessitating prolonged fasting have a high mortality in low-income settings, partially due to malnutrition and electrolyte disturbances in the absence of parenteral nutrition (PN). Interventions to address these problems require an accurate baseline quantification of the morbidity and mortality of this population. This prospective study aimed to determine peri-operative morbidity, fluid and electrolyte disturbance, growth, and mortality in neonates with gastroschisis (GS), intestinal atresia (IA), and esophageal atresia (EA) in Uganda.MethodsStandardized patient care of 45 neonates treated in Uganda from Oct 2021 to March 2022 with protocolized fluid and nutrition, vital signs, and routine laboratory measurements. Patient demographics, admission and hospital characteristics are described with mean ± SD. Characteristics of survivors and non-survivors were compared with Fischer's exact tests, logrank tests, and CoX Ph model.ResultsTwenty-eight (62.2%) patients had GS, 4 (8.9%) EA, and 13 (28.9%) IA. Thirty-six percent (16/44) of patients survived to discharge (26% GS, 50% EA, 54% IA) with an average length of stay of 17.3 days ( ± 2.2) (survivors) and 9 days ( ± 1.7) (non-survivors). Average weight was 2.21 kg ( ± 0.62) at presentation, with no significant weight change during the study. Abnormal serum sodium in 64%, phosphate 36.5%, and magnesium 20.8% of measurements. Mortality did not correlate with diagnosis (p = 0.47), electrolyte derangement, or weight change.ConclusionMortality of neonates born with GS, EA, and IA is high in Uganda. Malnutrition and fluid/electrolyte derangements are common and may affect mortality. This study provides a comparison group for studying interventions to improve outcomes for these populations.Type of studyProspective cohort.Level of evidenceLevel 3. 相似文献

IntroductionConcomitant patellar tendon (PT) tear with cruciate or multi-ligament knee injuries (MLKI) following high-velocity injury requires a systematic approach.MethodsThe study is a retrospective case series of patients (2008–2019) with concomitant PT ligament injury with cruciate or collateral ligament injury (MLKI), including bony avulsion injuries. Isolated cruciate and MLKI without patellar tendon tears are excluded. N = 32 patients (1 female and 31 male) are divided into two groups, Group 1 (11 patients) with PT tear and ACL tear and group 2 (21 patients) with PT tear and MLKIs. Patients were taken up for a single stage in types 1,2,3 and staged repair with reconstruction for types 4,5 of our new classification. All the patients are followed up regularly, and IKDC and Lyshom's score and objective radiological stress x-rays taken at each follow-upResultsIncidence of PTT combined injuries among all knee ligament injuries is 0.57%. The mean age was 35.09+/-11.96 SD(group1) and 36.55+/-11.89 SD(group2). The average follow-up was 34.45 months +/- 12.86SD (group 1) and 35.3 months +/- 15.75 SD (group2). Mean post-operative Lysholm score and IKDC score of group 1 and group 2 improvement was statistically significant p-value <=0.01. The mean post-operative ROM of the two groups were 132.73 (SD 6.46) (Group 1) and 111.75 (15.75) (Group 2) and was a statistically significant p-value <0.01. Residual lag of 30° seen in all patients improved by 3rd month in group 1 and 6th month in group 2. Knee stiffness is seen in 2 patients and superficial infection in 2 patients.ConclusionPTT combined injuries are rare and occurs due to direct impact injuries. Single-stage PT repair with ACL reconstruction gives adequate stability, and extensor lag is eminent and needs supervised rehabilitation. PT with MLKI is a challenging scenario that can be performed in single-stage/multiple stages, depending on the injuries, surgical expertise, and institutional facilities. Newer simplified classification aids surgeons in planning a treatment strategy. 相似文献

ObjectiveThe study objective was to investigate the long-term survival of patients undergoing xenograft versus homograft full root aortic valve replacement.MethodsA total of 166 patients requiring aortic valve surgery were randomized to undergo the Freestyle (Medtronic Inc, Minneapolis, Minn) bioprosthesis (N = 90) or a homograft (N = 76) full root aortic valve replacement between 1997 and 2005 in a single institution. Six patients randomly assigned to the homograft crossed over to the Freestyle bioprosthesis because of the unavailability of suitably sized homografts. All surgeons were required to adhere to the standard surgical technique for homograft root implantation previously described. Follow-up was 98.5% complete.ResultsThe mean age of the study population was 65 ± 8 years. Coronary artery bypass grafting was associated with root aortic valve replacement in 76 of 166 patients (46%, P = not significant between groups), and overall hospital mortality was 4.8% (8/166, P = not significant between groups). Median follow-up was 13.8 years (range, 0-21.8 years; 2033 patient-years). The Kaplan–Meier survival analysis showed that there was no significant difference in overall survival between the 2 arms at 5, 10, and 15 years. Twenty-year survival was 28.3% ± 5% for the Freestyle group versus 25.1% ± 5.7% for the homograft group (P = .90), which was comparable to the age- and sex-matched UK general population. The freedom from aortic valve reoperation at 20 years was comparable for the Freestyle group versus the homograft group (67.9% ± 8.8% vs 67.2% ± 10.3%, respectively; P = .74).ConclusionsThis is the first study to investigate the long-term survival of xenograft versus homograft full root aortic valve replacement from a prospective randomized trial. The observed 20-year overall survival and freedom from aortic valve reoperation serve as a benchmark for future studies on interventions for aortic valve disease in the elderly. 相似文献

BackgroundExtreme lateral interbody fusion (XLIF) is often used with posterior spinal fixation (PSF) to treat adult spinal deformity (ASD). However, the amount of intraoperative blood loss (IBL) reported for XLIF may underestimate the total blood loss (TBL). The objective of this study was to determine the total perioperative blood loss in XLIF for ASD.MethodsWe assessed 30 consecutive ASD patients with Schwab-SRS type L (mean age: 68.7 ± 8.2 years; mean follow-up 2.0 ± 1.3 years) who were treated by multilevel XLIF (mean, 2.5 ± 0.6 levels) followed by PSF after 3–5 days. We calculated the TBL after XLIF by the Gross equation, by hemoglobin (Hb) balance, and by the Orthopedic Surgery Transfusion Hemoglobin European Overview (OSTHEO) formula. We defined hidden blood loss (HBL) as the difference between the TBL and IBL. Pearson correlation, Spearman correlation, and multiple logistic regression analysis were performed to investigate the risk factors related to HBL.ResultsPost-XLIF blood tests showed a significant decrease in the Hb (from 11.8 ± 1.1 mg/dl to 10.6 ± 1.1 mg/dl) and hematocrit (from 36.0 ± 3.2% to 32.5 ± 3.2%). Although the mean IBL was relatively small (33 ± 52 mL), we calculated the TBL as 291 ± 171 mL (Gross equation) and the HBL as 258 ± 168 mL by Gross equation, which was 8 times greater than the IBL on average. There was no difference in the results obtained using the three methods. Multiple logistic regression analysis indicated preoperative lumber lordosis was the risk factor of high HBL (Odds ratio = 1.085, 95%CI: 1.006–1.170, p = 0.035).ConclusionsThe HBL in XLIF was 8 times greater than the IBL. During the perioperative course of correction and fusion surgery for ASD with XLIF, surgeons need to pay attention not to underestimate the TBL. 相似文献

ObjectiveSutureless aortic valves are a novel option for aortic valve replacement. We sought to demonstrate noninferiority of sutureless versus standard bioprostheses in severe symptomatic aortic stenosis.MethodsThe Perceval Sutureless Implant Versus Standard-Aortic Valve Replacement is a prospective, randomized, adaptive, open-label trial. Patients were randomized (March 2016 to September 2018) to aortic valve replacement with a sutureless or stented valve using conventional or minimally invasive approach. Primary outcome was freedom from major adverse cerebral and cardiovascular events (composite of all-cause death, myocardial infarction, stroke, or valve reintervention) at 1 year.ResultsAt 47 centers (12 countries), 910 patients were randomized to sutureless (n = 453) or conventional stented (n = 457) valves; mean ages were 75.4 ± 5.6 and 75.0 ± 6.1 years, and 50.1% and 44.9% were female, respectively. Mean ± standard deviation Society of Thoracic Surgeons scores were 2.4 ± 1.7 and 2.1 ± 1.3, and a ministernotomy approach was used in 50.4% and 47.3%, respectively. Concomitant procedures were performed with similar rates in both groups. Noninferiority was demonstrated for major adverse cerebral and cardiovascular events at 1 year, whereas aortic valve hemodynamics improved equally in both groups. Use of sutureless valves significantly reduced surgical times (mean extracorporeal circulation times: 71.0 ± 34.1 minutes vs 87.8 ± 33.9 minutes; mean crossclamp times: 48.5 ± 24.7 vs 65.2 ± 23.6; both P < .0001), but resulted in a higher rate of pacemaker implantation (11.1% vs 3.6% at 1 year). Incidences of perivalvular and central leak were similar.ConclusionsSutureless valves were noninferior to stented valves with respect to major adverse cerebral and cardiovascular events at 1 year in patients undergoing aortic valve replacement (alone or with coronary artery bypass grafting). This suggests that sutureless valves should be considered as part of a comprehensive valve program. 相似文献
