Open in a separate window OBJECTIVESThe aim of this study is to describe the significance of symptoms preoperatively and at medium-term follow-up in adolescent and adult patients who underwent surgery of anomalous aortic origin of a coronary artery (AAOCA).METHODSConsecutive patients who underwent surgery for AAOCA in our tertiary referral centre between 2001 and 2018 were included. Clinical characteristics and symptoms were evaluated and medium-term outcomes were recorded. Symptoms were classified according to the ‘2019 ESC guidelines on chronic coronary syndromes’.RESULTSA total of 53 (55% male) patients with mean age of 44 at time of surgery underwent surgical repair of AAOCA. Data on symptoms and events ˃3 months after surgery were available in 34 patients with a median follow-up of 3 years (interquartile range 1.0–5.3). Preoperatively, only 35% patients had typical anginal complaints. After surgical correction of AAOCA, 59% of the patients were free of symptoms, compared to 6% preoperatively (P < 0.001). A total of 3 (9%) patients needed a reoperation/reintervention related to the operated AAOCA. All 3 patients presented postoperatively with novel typical anginal complaints.CONCLUSIONSAdolescent and adult patients with AAOCA present with varying symptoms. Only 35% have typical anginal complaints. Surgical correction of AAOCA reduces the symptoms in the vast majority of patients. One should be aware of potential lesions of the operated coronary artery in patients presenting with typical anginal complaints postoperatively. 相似文献

OBJECTIVESThe aim was to compare the relative effects of red blood cell (RBC) transfusion and preoperative anaemia on 5-year mortality following open-heart cardiac surgery using structural equation modelling. We hypothesized that patient risk factors associated with RBC transfusion are of larger importance than transfusion itself.Open in a separate windowMETHODSThis prospective cohort study, part of the Cardiac Surgery Outcome Study at St. Olavs University Hospital, Trondheim, Norway, included open-heart on-pump cardiac surgery patients operated on from 2000 through 2017 (n = 9315). Structural equation modelling, which allows for intervariable correlations, was used to analyse pathway diagrams between known risk factors and observed mortality between 30 days and 5 years postoperatively. Observation times between 30 days and 1 year, and 1–5 years postoperatively were also compared with the main analysis.RESULTSIn a simplified model, preoperative anaemia had a larger effect on 5-year mortality than RBC transfusion (standardized coefficients: 0.17 vs 0.09). The complete model including multiple risk factors showed that patient risk factors such as age (0.15), anaemia (0.10), pulmonary disease (0.11) and higher creatinine level (0.12) had larger effects than transfusion (0.03). Results from several sensitivity analyses supported the main findings. The models showed good fit.CONCLUSIONSPreoperative anaemia had a larger impact on 5-year mortality than RBC transfusion. Differences in 5-year mortality were mainly associated with patient risk factors. 相似文献

OBJECTIVESThe present study aimed to clarify the association between preoperative biopsy and surgical outcomes in clinical stage I non-small-cell lung cancer (NSCLC) with different proportions of ground-glass opacity (GGO).Open in a separate windowMETHODSData on patients who underwent pulmonary resection for NSCLC from 2006 to 2016 were drawn from a prospective registered database and analysed retrospectively. Patient characteristics collected included tumour size, location and staging, surgical approach, consolidation–tumour ratio, histopathology and the presence or absence of preoperative biopsy to identify the independent prognostic factors of disease-free survival (DFS) and cancer-specific survival. A 1:1 propensity score matching was conducted between the preoperative biopsy and reference groups based on their baseline characteristics measured before the decision for preoperative biopsy.RESULTSA total of 1427 patients were collected to achieve an overall 5-year DFS as 84.5% (median follow-up: 67.3 months), stratified to be 99.5% in the GGO-dominant group (n = 430) and 78.2% in the solid-dominant group (n = 997). Only 2 patients (0.5%) in the GGO-dominant group experienced tumour recurrence. For solid-dominant tumours matched with propensity scores (279 in preoperative biopsy vs 279 in reference group), the independent predictors of DFS included preoperative biopsy, sublobar resection, pathological staging and angiolymphatic invasion. Preoperative biopsy was a predictor of cancer-specific survival in univariable analysis but was not in multivariable analysis. Significant differences were also found between matched groups in those with late-delay surgery, but not in patients receiving preoperative biopsy with early-delay surgery (≤21 days).CONCLUSIONPreoperative biopsy may worsen surgical outcomes in patients with clinical stage I, solid-dominant NSCLC. 相似文献

Open in a separate window OBJECTIVESSoluble urokinase plasminogen activator receptor (suPAR) is a biomarker that has been implicated in several cardiac pathologies and has been shown to be elevated in critically ill populations. We measured plasma suPAR in a cohort of cardiac surgical patients to evaluate its ability to predict prolonged intensive care unit (ICU) and hospital length of stay and development of complications following surgery. We compared suPAR against EuroSCORE II and C-reactive protein (CRP).METHODSNinety patients undergoing cardiac surgery were recruited with samples taken preoperatively and on postoperative days 1, 2 and 3. suPAR was measured using enzyme-linked immunosorbent assay. Area under the receiver operator curve (AUROC) was used to test predictive capability of suPAR. Comparison was made with EuroSCORE II and CRP.RESULTSsuPAR increased over time (P < 0.001) with higher levels in patients requiring prolonged ICU and hospital stay, and prolonged ventilation (P < 0.05). suPAR was predictive for prolonged ICU and hospital stay, and prolonged ventilation at all time points (AUROC 0.66–0.74). Interestingly, this association was also observed preoperatively, with preoperative suPAR predicting prolonged ICU (AUROC 0.66), and hospital stay (AUROC 0.67) and prolonged ventilation (AUROC 0.74). The predictive value of preoperative suPAR compared favourably to EuroSCORE II and CRP.CONCLUSIONSsuPAR increases following cardiac surgery and levels are higher in those who require prolonged ICU stay, prolonged hospital stay and prolonged ventilation. Preoperative suPAR compares favourably to EuroSCORE II and CRP in the prediction of these outcomes. suPAR could be a useful biomarker in predicting outcome following cardiac surgery, helping inform clinical decision-making.Clinical registrationWest of Scotland Research Ethics Committee Reference: 12/WS/0179 (AM01). 相似文献

OBJECTIVESIn patients with unknown coronary status undergoing surgery for acute infective endocarditis (IE), the need to screen for coronary artery disease (CAD) and the risk of embolization during invasive coronary angiography (ICA) are debated. Coronary computed tomography angiography (CCTA) is a non-invasive alternative in these patients. We aimed to evaluate the safety and feasibility of ICA and CCTA to diagnose CAD, and the necessity to treat CAD to prevent CAD-related postoperative complications. Open in a separate windowMETHODSIn this single-centre retrospective cohort study, all patients with acute aortic IE between 2009 and 2019 undergoing surgery were selected. Outcomes were any clinically evident embolization after preoperative ICA, in-hospital mortality, perioperative myocardial infarction or unplanned revascularization and postoperative renal function.RESULTSOf the 159 included patients, CAD status was already known in 14. No preoperative diagnostics for CAD was done in 46/145, a CCTA was performed in 54/145 patients and an ICA in 52/145 patients. Significant CAD was found after CCTA in 22% and after ICA in 21% of patients. In 1 of the 52 (2%) patients undergoing preoperative ICA, a cerebral embolism occurred. The rate of perioperative myocardial infarction or unplanned revascularization in patients not screened for CAD was 2% (1 out of 46 patients).CONCLUSIONSAlthough the risk of embolism after preoperative ICA is low, it should be carefully weighed against the estimated risk of CAD-related perioperative complications. CCTA can serve as a gatekeeper for ICA in most patients with acute aortic IE. 相似文献

Open in a separate window OBJECTIVESRenal transplantation is an effective treatment for end-stage renal failure. The aim of this study was to evaluate outcomes for these patients undergoing cardiac surgery.METHODSA retrospective analysis identified patients with a functioning renal allograft at the time of surgery. A 2:1 propensity matching was performed. Patients were matched on: age, sex, left ventricle function, body mass index, preoperative creatinine, operation priority, operation category and logistic EuroSCORE.RESULTSThirty-eight patients undergoing surgery with a functioning renal allograft were identified. The mean age was 62.4 years and 66% were male. A total of 44.7% underwent coronary artery bypass grafting and 26.3% underwent a single valve procedure. The mean logistic EuroSCORE was 10.65. The control population of 76 patients was well matched. Patients undergoing surgery following renal transplantation had a prolonged length of intensive care unit (3.19 vs 1.02 days, P < 0.001) and hospital stay (10.3 vs 7.17 days, P = 0.05). There was a higher in-hospital mortality (15.8% vs 1.3%, P = 0.0027). Longer-term survival on Kaplan–Meier analysis was also inferior (P < 0.001). One-year survival was 78.9% vs 96.1% and 5-year survival was 63.2% vs 90.8%. A further subpopulation of 11 patients with a failed renal allograft was identified and excluded from the main analysis; we report demographic and outcome data for them.CONCLUSIONSPatients with a functioning renal allograft are at higher risk of perioperative mortality and inferior long-term survival following cardiac surgery. Patients in this population should be appropriately informed at the time of consent and should be managed cautiously in the perioperative period with the aim of reducing morbidity and mortality. 相似文献

OBJECTIVESThis study aimed to determine whether changes in perioperative N-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with short-term outcomes in children undergoing surgery for congenital heart disease (CHD).Open in a separate windowMETHODSWe retrospectively included 873 consecutive children with CHD after cardiac surgery. NT-proBNP concentrations were collected from each child prior to and at 1, 12, 36 and 72 h after surgery. The patients had postsurgical follow-ups at 30, 90 and 180 days. The end point was postoperative composite adverse events.RESULTSThe patients were classified into 3 groups using joint latent class mixture time-to-event models: (i) relatively stable (86.7%), (ii) decreasing (7.2%) and (iii) increasing (6.1%). In total, 257 (29.4%) adverse events occurred. The joint latent class mixture time-to-event models showed that increasing NT-proBNP was strongly associated with adverse events, with adjusted hazard ratio of 2.33 (95% confidence interval 1.52–3.60). Multinomial logistic regression showed that the variables associated with the pattern of change were age, weight at surgery, mode of delivery and cardiopulmonary bypass time.CONCLUSIONSThe pattern of dynamic postsurgical changes in NT-proBNP may facilitate outcome stratification and identification of a high risk for adverse events. 相似文献

OBJECTIVESGuidelines advocate that patients being considered for thoracic surgery should undergo a comprehensive preoperative risk assessment. Multiple risk prediction models to estimate the risk of mortality after thoracic surgery have been developed, but their quality and performance has not been reviewed in a systematic way. The objective was to systematically review these models and critically appraise their performance.Open in a separate windowMETHODSThe Cochrane Library and the MEDLINE database were searched for articles published between 1990 and 2019. Studies that developed or validated a model predicting perioperative mortality after thoracic surgery were included. Data were extracted based on the checklist for critical appraisal and data extraction for systematic reviews of prediction modelling studies.RESULTSA total of 31 studies describing 22 different risk prediction models were identified. There were 20 models developed specifically for thoracic surgery with two developed in other surgical specialties. A total of 57 different predictors were included across the identified models. Age, sex and pneumonectomy were the most frequently included predictors in 19, 13 and 11 models, respectively. Model performance based on either discrimination or calibration was inadequate for all externally validated models. The most recent data included in validation studies were from 2018. Risk of bias (assessed using Prediction model Risk Of Bias ASsessment Tool) was high for all except two models.CONCLUSIONSDespite multiple risk prediction models being developed to predict perioperative mortality after thoracic surgery, none could be described as appropriate for contemporary thoracic surgery. Contemporary validation of available models or new model development is required to ensure that appropriate estimates of operative risk are available for contemporary thoracic surgical practice. 相似文献

OBJECTIVESAmong patients undergoing transcatheter mitral valve repair with the MitraClip device, a relevant proportion (2–6%) requires open mitral valve surgery within 1 year after unsuccessful clip implantation. The goal of this review is to pool data from different reports to provide a comprehensive overview of mitral valve surgery outcomes after the MitraClip procedure and estimate in-hospital and follow-up mortality. Open in a separate windowMETHODSAll published clinical studies reporting on surgical intervention for a failed MitraClip procedure were evaluated for inclusion in this meta-analysis. The primary study outcome was in-hospital mortality. Secondary outcomes were in-hospital adverse events and follow-up mortality. Pooled estimate rates and 95% confidence intervals (CIs) of study outcomes were calculated using a DerSimionian–Laird binary random-effects model. To assess heterogeneity across studies, we used the Cochrane Q statistic to compute I2 values.RESULTSOverall, 20 reports were included, comprising 172 patients. Mean age was 70.5 years (95% CI 67.2–73.7 years). The underlying mitral valve disease was functional mitral regurgitation in 50% and degenerative mitral regurgitation in 49% of cases. The indication for surgery was persistent or recurrent mitral regurgitation (grade >2) in 93% of patients, whereas 6% of patients presented with mitral stenosis. At the time of the operation, 80% of patients presented in New York Heart Association functional class III–IV. Despite favourable intraoperative results, in-hospital mortality was 15%. The rate of periprocedural cerebrovascular accidents was 6%. At a mean follow-up of 12 months, all-cause death was 26.5%. Mitral valve replacement was most commonly required because the possibility of valve repair was jeopardized, likely due to severe valve injury after clip implantation.CONCLUSIONSSurgical intervention after failed transcatheter mitral valve intervention is burdened by high in-hospital and 1-year mortality, which reflects reflecting the high-risk baseline profile of the patients. Mitral valve replacement is usually required due to leaflet injury. 相似文献

OBJECTIVESMany surgeons develop unique techniques for unmet needs for right ventricular outflow reconstruction to resolve pulmonary regurgitation after corrective surgery for congenital heart diseases. Expanded polytetrafluoroethylene (ePTFE) stands out as a reliable synthetic material, and clinical results with handmade ePTFE valves have been promising. This review focuses on the historical evolution of the use of ePTFE in pulmonary valve replacement and in the techniques for pioneering the translation of the handmade ePTFE trileaflet design for the transcatheter approach.Open in a separate windowMETHODSWe searched for and reviewed publications from 1990 to 2020 in the Pubmed database. Nineteen clinical studies from 2005 to 2019 that focused on ePTFE-based valves were summarized. The evolution of the ePTFE-based valve over 3 decades and recent relevant in vitro studies were investigated.RESULTSThe average freedom from reintervention or surgery in the recorded ePTFE-based valve population was 90.2% at 5 years, and the survival rate was 96.7% at 3 years.CONCLUSIONSNon-inferior clinical results of this ePTFE handmade valve were revealed compared to allograft or xenograft options for pulmonary valve replacement. Future investigations on transferring ePTFE trileaflet design to transcatheter devices should be considered. 相似文献

Open in a separate window OBJECTIVESThere is growing interest in the aortic valve (AV) neocuspidalization technique for the treatment of aortic valve disease (AVD). We report our medium-term results with this procedure performed in a paediatric patient population.METHODSBetween July 2016 and May 2020, 22 patients with both congenital and acquired isolated AVD were treated with neocuspidalization. The primary outcome was progression of the preoperatively assessed AVD in the immediate postoperative course and at follow-up. Secondary outcome was freedom from reintervention by material used. Potential predictors of failure were analysed in relation to the primary outcome.RESULTSThe median age at operation was 13.9 (interquartile range, 9.8–16.2) years, and the prevailing AV defect was stenosis in 10 cases (45%) and incompetence in 12 (55%). Pre-treated autologous pericardium was used in 13 patients whereas bovine pericardium in 9. Effective treatment of AV stenosis or regurgitation was achieved and remained stable over a median follow-up of 11.3 (4.7–21) months. Three patients required AV replacement at 4.9, 3.5 and 33 months. At follow-up, an upward trend of both median indexed vena contracta jet widths and aortic peak and mean gradients were recorded, the latter associated with a failure to grow the aortic annulus. Predictor of such outcome turned out to be the use of bovine pericardium. A significant inverse linear correlation between AV peak gradient at follow-up and preoperative aortic annular size (P = 0.008) was also demonstrated.CONCLUSIONSThe Ozaki procedure is safe and effective in paediatric patients with AV disease. The use of heterologous pericardium should probably be minimized. Moreover, preoperative small aortic annuli should probably be promptly treated by means of an associated ring enlargement procedure. 相似文献

Open in a separate window OBJECTIVESNeonates with dextro-transposition of the great arteries (d-TGA) may experience rapid haemodynamic deterioration and profound hypoxaemia after birth. We report on d-TGA patients with severe acidosis, encephalopathy and their treatment with systemic hypothermia.METHODSThis study is a single-centre retrospective cohort analysis of newborns with d-TGA.RESULTSNinety-five patients (gestational age ≥35 weeks) with d-TGA and intended arterial switch operation were included. Ten infants (10.5%) with umbilical arterial blood pH > 7.10 experienced profound acidosis (pH < 7.00) within the first 2 h of life. Six of these patients displayed signs of encephalopathy and received therapeutic hypothermia. Apgar scores at 5 min independently predicted the development of neonatal encephalopathy during postnatal transition (unit Odds Ratio 0.17, 95% confidence interval 0.06–0.49, P = 0.001). Infants treated with hypothermia had a more severe preoperative course and required more often mechanical ventilation (100% vs 35%, P = 0.003), treatment with inhaled nitric oxide (50% vs 2.4%, P = 0.002) and inotropic support (67% vs 3.5%, P < 0.001), as compared to non-acidotic controls. The median age at cardiac surgery was 12 (range 6–14) days in cooled infants and 8 (4–59) days in controls (P = 0.088). Postoperative morbidity and total duration of hospitalization were not increased in infants receiving preoperative hypothermia. Mortality in newborns with severe preoperative acidosis was zero.CONCLUSIONSNewborn infants with d-TGA have a substantial risk for profound acidosis during the first hours of life. Systemic hypothermia for encephalopathic patients may delay corrective surgery without compromising perioperative outcomes. 相似文献

Open in a separate windowOBJECTIVESAssessment of early outcomes in patients with normal preoperative left ventricular ejection fraction (LVEF) in whom venoarterial extracorporeal membrane oxygenation (VA-ECMO) was implanted for postcardiotomy cardiogenic shock (PCCS) during the first postoperative 48 h. METHODSRetrospective single-centre analysis in adult patients with normal LVEF, who received VA-ECMO support for PCCS from May 1998 to May 2018. The primary outcome was 30-day perioperative mortality during the index hospitalization.RESULTSA total of 62 125 adult patients underwent cardiac surgery at our institution during the study period. Among them, 173 patients (0.3%) with normal preoperative LVEF required VA-ECMO for PCCS. Among them, 71 (41.1%) patients presented PCCS due to coronary malperfusion and in 102 (58.9%) patients, no evident cause was found for PCCS. Median duration of VA-ECMO support was 5 days (interquartile range 2–8 days). A total of 135 (78.0%) patients presented VA-ECMO-related complications and the overall 30-day perioperative mortality was 57.8%. Independent predictors of mortality were: lactate level just before VA-ECMO implantation [odds ratio (OR) 1.27; P < 0.001], major bleeding during VA-ECMO (OR 3.76; P = 0.001), prolonged cardiopulmonary bypass time (OR 1.01; P < 0.001) and female gender (OR 4.87; P < 0.001).CONCLUSIONSMortality rates of VA-ECMO in PCCS patients are high, even in those with preoperative normal LVEF. Coronary problems are an important cause of PCCS; however, the aetiology remains unknown in the vast majority of the cases. The implantation of VA-ECMO before development of tissue hypoperfusion and the control of VA-ECMO-associated complications are the most important prognostic factors in PCCS patients. Lactate levels may help guide timing of VA-ECMO implantation and define the extent of therapeutic effort. 相似文献

OBJECTIVESWe herein report a single-centre experience with the SAPIEN 3 Ultra balloon-expandable transcatheter aortic valve implantation (TAVI) system.METHODSBetween March 2019 and January 2020, a total of 79 consecutive patients received transfemoral TAVI using the SAPIEN 3 Ultra device. Data were retrospectively analysed according to updated Valve Academic Research Consortium-2 definitions. Detailed analysis of multislice computed tomography data was conducted to identify potential predictors for permanent pacemaker (PPM) implantation and residual paravalvular leakage (PVL) post TAVI.Open in a separate windowGraphical AbstractRESULTSDevice success and early safety were 97.5% (77/79) and 94.9% (75/79) with resulting transvalvular peak/mean pressure gradients of 21.1 ± 8.2/10.9 ± 4.4 and PVL >mild in 0/79 patients (0%). Mild PVL was seen in 18.9% (15/79) of cases. Thirty-day mortality was 2.5% (2/79). The Valve Academic Research Consortium-2 adjudicated clinical end points disabling stroke, acute kidney injury and myocardial infarction occurred in 1.3% (1/79), 5.1% (4/79) and 0% (0/79) of patients. Postprocedural PPM implantation was necessary in 7.6% (6/79) of patients. Multislice computed tomography analysis revealed significantly higher calcium amounts of the right coronary cusp in patients in need for postprocedural PPM implantation and a higher eccentricity index in patients with postinterventional mild PVL.CONCLUSIONSFirst experience with this newly designed balloon-expandable-transcatheter heart valve demonstrates adequate 30-day outcomes and haemodynamic results with low mortality, low rates of PPM implantation and no residual PVL >mild. The herein-presented multislice computed tomography values with an elevated risk for PPM implantation and residual mild PVL may help to further improve outcomes with this particular transcatheter heart valve in TAVI procedures. 相似文献

Open in a separate windowOBJECTIVESConduction disorders and the need for permanent pacemaker (PPM) implantation after surgical aortic valve replacement are well-recognized complications. However, in the case of sutureless valve prostheses, it remains unknown whether pacemaker (PM) dependency and conduction disturbances resolve over time. Our aim was to evaluate whether conduction disorders after Perceval sutureless valve implantation recover during follow-up. METHODSPatients undergoing isolated surgical aortic valve replacement or concomitant aortic valve replacement with coronary artery bypass surgery using the Perceval sutureless valve, between January 2010 and July 2018, were included. Postoperative electrocardiogram findings were analysed to determine the incidence of new-onset left bundle branch blocks (LBBBs) and the requirement for PPM implantation. During a postoperative period of 6–18 months, electrocardiogram findings during PM checks were analysed to determine PM dependency and LBBB persistence.RESULTSOut of 184 patients who received a Perceval prosthesis during the study period, 39 (21.2%) patients developed new-onset LBBB and 10 patients (5.4%) received a PPM postoperatively. The occurrence of conduction disorders was not associated with valve size. Follow-up was completed in 176 (95.7%) patients. In patients with a new-onset LBBB, 35.9% recovered during follow-up (P = 0.001). Seven out of 10 (70%) patients remained PM dependent.CONCLUSIONSAfter Perceval aortic valve implantation, new-onset LBBB recovers in more than one-third of patients during follow-up. In patients who needed a postoperative PPM, the majority remained PM dependent. 相似文献

Open in a separate window OBJECTIVESThe increasing complexity of surgical patients and working time constraints represent challenges for training. In this study, the European Association for Cardio-Thoracic Surgery Residents’ Committee aimed to evaluate satisfaction with current training programmes across Europe. METHODSWe conducted an online survey between October 2018 and April 2019, completed by a total of 219 participants from 24 countries.RESULTSThe average respondent was in the fourth or fifth year of training, mostly on a cardiac surgery pathway. Most trainees follow a 5–6-year programme, with a compulsory final certification exam, but no regular skills evaluation. Only a minority are expected to take the examination by the European Board of Cardiothoracic Surgery. Participants work on average 61.0 ± 13.1 h per week, including 27.1 ± 20.2 on-call. In total, only 19.7% confirmed the implementation of the European Working Time Directive, with 42.0% being unaware that European regulations existed. Having designated time for research was reported by 13.0%, despite 47.0% having a postgraduate degree. On average, respondents rated their satisfaction 7.9 out of 10, although 56.2% of participants were not satisfied with their training opportunities. We found an association between trainee satisfaction and regular skills evaluation, first operator experience and protected research time.CONCLUSIONSOn average, residents are satisfied with their training, despite significant disparities in the quality and structure of cardiothoracic surgery training across Europe. Areas for potential improvement include increasing structured feedback, research time integration and better working hours compliance. The development of European guidelines on training standards may support this. 相似文献

Open in a separate window OBJECTIVESThoracic endometriosis syndrome (TES) is the presence of functional endometrial tissue in or around the lung. There seem to be differences in the clinical presentation of this condition among Nigerian patients. We aim to study the clinical presentation and management outcome of TES in our centre. METHODSThis is an analysis of consecutive patients with TES treated over a 5-year period and followed up for 6 months to 5 years. Information collected included the gynaecological history, clinical presentation, causes of misdiagnosis, modalities of treatment and outcome.RESULTSTwenty-three patients with TES aged between 24 and 45 years (median 32 years) were treated. Severe dysmenorrhoea was a prominent symptom in 91.3% of cases (median dysmenorrhoea score 8) and was uninfluenced by the marital status (P = 0.522). The patients usually presented with massive or recurrent haemothorax associated with massive ascites [16/23 (69.5%) of cases (P = 0.0006)]. The right side alone was involved in 21 cases and 1 patient had catamenial haemoptysis as a part of her symptoms, even though there was bronchial bleed at bronchoscopy in 6 patients. In 40%, tuberculosis was the misdiagnosis. Diagnosis was established histologically in 18/23 (78.3%) of the cases. Treatment was multimodal and multidisciplinary with notable macroscopic lesions in 77.8% of the patients that had surgery.CONCLUSIONSTES is not an uncommon lesion. Presentation with massive haemothorax is usually associated with massive ascites. A large percentage of such have pleural and diaphragmatic lesions that require surgical treatment. The ascites may be refractory to treatment requiring repeated paracentesis. 相似文献

OBJECTIVESThe inflammatory response after surgery is associated with patient prognosis. Patients who undergo thoracic surgery exhibit a profound systemic inflammatory response due to the surgical procedures used and application of one-lung ventilation. The aim of this study was to compare perioperative inflammatory changes in patients after intubated and non-intubated thoracic surgery for primary lung cancer resection.Open in a separate windowMETHODSThis prospective randomized controlled study included forty patients who underwent surgical resection for stage I non-small-cell lung cancer. Blood samples for cytokine analysis were collected just before induction, at 1 and 24 h after surgery. Levels of the pro-inflammatory cytokine and anti-inflammatory cytokines were measured using quantitative sandwich enzyme immunoassay kits.RESULTSThe basal values of cytokines were comparable between 2 groups. Within each group, the postoperative levels of interleukin (IL)-1, IL-6 and tumour necrosis factor-α increased, while those of IL-4 and IL-10 did not change significantly. The levels of IL-6 and tumour necrosis factor-α were significantly lower in group NI at 1 and 24 h postoperatively. Other cytokines did not differ in both groups during postoperative period. The IL-6/IL-10 ratio at 1 h after surgery was lower in non-intubated patients than in intubated patients, but there was no difference at 24 h after surgeryCONCLUSIONSNon-intubated thoracic surgery may attenuate the early inflammatory cytokine changes following major resection for primary lung cancer compared with intubated conventional surgery.Clinical trial registrationClinicalTrials.gov registry number NCT04007354相似文献

OBJECTIVESDurability of sutureless aortic bioprosthetic valves remains a major issue. The aim of this study was to assess structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) of the Perceval bioprosthesis using the new proposed standardized definitions.Open in a separate windowMETHODSAll patients who underwent aortic valve replacement with sutureless Perceval S prostheses up to September 2016 were included. Clinical and echocardiographic follow-up was performed. New standardized definitions were used to assess the durability of sutureless bioprosthetic valves. From 2013 to 2016, 214 patients were included.RESULTSThe mean age and EuroSCORE II were 79 years and 2.74. Thirty-day mortality was 0.47%. The survival rate was 96.8%, 88.1% and 85.7% at 1, 3 and 4 years, respectively. The median echocardiographic follow-up was 3.28 years. The mean pressure gradient was 11.3 mmHg. No cases showed evidence of severe SVD, 17 patients had moderate SVD with a mean pressure gradient of 24 mmHg and 8 patients had definite late BVF. The incidence of moderate SVD and BVF at 4 years was 8.8% and 2.9%, respectively.CONCLUSIONSMid-term follow-up to 6.3 years after aortic valve replacement with the Perceval bioprosthesis documents favourable haemodynamic and clinical outcomes and low rates of SVD and BVF. 相似文献

Open in a separate windowOBJECTIVESWith development of antegrade cerebral perfusion, the necessity of deep hypothermic circulatory arrest (CA) in aortic arch surgery has been called into question. To minimize the adverse effects of hypothermia, surgeons now perform these procedures closer to normothermia. This study examined postoperative outcomes of hemiarch replacement patients using unilateral selective antegrade cerebral perfusion and mild hypothermic CA.METHODSSingle-centre retrospective review of 66 patients undergoing hemiarch replacement with mild hypothermic CA (32°C) and unilateral selective antegrade cerebral perfusion between 2011 and 2018. Antegrade cerebral perfusion was delivered using right axillary artery cannulation. Postoperative data included death, neurological dysfunction, acute kidney injury and renal failure requiring new dialysis. Additional intraoperative metabolic data and blood transfusions were obtained.RESULTSEighty-six percent of patients underwent elective surgery. Mean age was 67 ± 3 years. Lowest mean core body temperature was 32 ± 2°C. Average CA was 17 ± 5 min. No intraoperative or 30-day mortality occurred. Survival was 97% at 1 year, 91% at 3 years and 88% at 5 years. Permanent and temporary neurological dysfunction occurred in 1 (2%) and 2 (3%) patients, respectively. Only 3 (5%) patients suffered postoperative stage 3 acute kidney injury requiring new dialysis. Intraoperative transfusions occurred in 44% of patients and no major metabolic derangements were observed.CONCLUSIONSIn patients undergoing hemiarch surgery, mild hypothermia (32°C) with unilateral selective antegrade cerebral perfusion via right axillary cannulation is associated with low mortality and morbidity, offering adequate neurological and renal protection. These findings require validation in larger, prospective clinical trials. 相似文献
