Hacettepe University Faculty of Medicine Department of Cardiovascular Surgery; data of 413 patients under 18 years old who had congenital heart surgery were evaluated between 01.01.2011-30.10.2012 and risk scorings were made by "RACHS-1 (Risk Adjustment in Congenital Heart Surgery)", "Aristotle Basic Complexity Score (ABS)" and "Aristotle Comprehensive Complexity Score (ACS)" systems used in evaluation of the risk of mortality and morbidity in (ACS)" systems used in evaluation of the risk of mortality and morbidity in congenital heart surgery. Data obtained were compared by Mann-Whitney U test and how effective these systems were in evaluating mortality and morbidity and their superiorities over each other were examined. Following the research, it was observed that all three systems were effective in evaluating mortality and morbidity; the most successful of them in foreseeing the event was the ACS system, ACS system was followed by RACHS-1 system and ABS system was the most incapable of these in foreseeing the event. It was seen that in detecting time related mortality, rating of these tests changed, RACHS-1 system detected the time related mortality best. It was also seen that with RACHS-1 system, a previously evaluated concept, it was possible to determine morbidity.

OBJECTIVES:Published experiences with thoracoscopic apical or total pleurectomy for patients with a pneumothorax are limited. We aimed to evaluate the long-term results and effectiveness of pleurectomy in our patients, that vast majority of whom underwent thoracoscopic apical or total pleurectomy. MATERIAL AND METHODS:Between January 2001 and December 2010, in the Istanbul University Medical School Department of Thoracic Surgery, 67 patients, consisting of 52 patients with a primary spontaneous pneumothorax and 15 with a secondary spontaneous pneumothorax who underwent 72 processes of thoracoscopic resection of blebs or bullae and pleural symphysis, consisting of 43% total pleurectomy, 42% apical pleurectomy plus pleural abrasion, and 15% non-pleurectomy pleurodesis procedures due to prolonged air leak or recurrent spontaneous pneumothorax, were analyzed retrospectively. The applied pleural procedures were: 1. total pleurectomy 2. apical pleurectomy and pleural abrasion for the remaining parts and 3. non-pleurectomy pleurodesis procedures. The long-term outcomes of patients undergoing the three different pleural procedures were compared. RESULTS:Total pleurectomy process, apical pleurectomy and abrasion process for remaining parietal pleura, and non-pleurectomy pleurodesis procedures were performed 31, 30, and 11 times, respectively. No recurrence was observed in the total pleurectomy group, 1 recurrence was observed for the apical pleurectomy plus pleural abrasion group, and 2 recurrences were observed for the nonpleurectomy group. CONCLUSION:Video-assisted thoracoscopic pleurectomy is a safe and effective method in spontaneous pneumothorax surgery. Especially, total pleurectomy has efficient results in the prevention of recurrences.

Objective: Ischemia reperfusion (I/R) injury is a common problem in vascular surgery. We aimed to investigate the effects of esmolol on erythrocyte deformability in rat lower limb I/R injury.

The patient-prosthesis mismatch has been reported as an important cause of adverse outcome following aortic valve replacement. The relief of patient-prosthesis mismatch generally requires a reoperation of comprehensive nature, which necessitates an extensive aortic root enlargement. The Konno aortoventriculoplasty represents an efficient treatment option, as this technique provides both extreme root enlargement and relief of the frequently associated subvalvular obstruction. However, the application and conduct of the procedure may somewhat differ from the pediatric Konno procedures.This article describes our surgical technique adaptation in Konno-aortoventriculoplasty for adult patient-prosthesis mismatch cases, highlighting the differing points from the pediatric-Konno.
