BACKGROUND Preoperative creatinine values higher than 2.5 mg/dL are associated with markedly increased risk for both mortality and morbidity in patients undergoing coronary artery bypass surgery. We aimed to determine the effects of prophylactic perioperative hemodialysis on operative outcome in patients with nondialysis-dependent moderate renal(More)
In the surgical treatment of abdominal aortic aneurysm, the single proximal cross-clamp can be placed at 3 alternative aortic levels: infrarenal, hiatal, and thoracic. We performed this retrospective study to evaluate the advantages and disadvantages of the 3 main aortic clamping locations. Eighty patients presented at our institution with abdominal aortic(More)
OBJECTIVE In this study, patients admitted with the diagnosis of Eisenmenger syndrome (ES) in a tertiary referral center were analyzed. METHODS The data of 20 consecutive patients (mean age: 27.6+1.8 years, 7 male and mean follow-up time: 35.6 ± 9.1 months) with ES were retrospectively analyzed. Demographic characteristics, symptoms, physical examination,(More)
Although it is a rare occurrence, aortic dissections can rupture into the cardiac chambers or great vessels. A review of the English literature revealed only 3 cases of fistula between an aortic false lumen and the main pulmonary artery that were repaired successfully. In this article, we report the case of a chronic type I aortic dissection with an(More)
The purpose of this study was to determine the effects of hiatal and thoracic clamping on postoperative outcome and morbidity and factors affecting mortality and morbidity. The records of 102 patients who had undergone ruptured abdominal aortic aneurysm repair between 1993 and 2005 were evaluated retrospectively. Hiatal clamping and thoracic clamping were(More)
BACKGROUND The radial artery was proposed and then abandoned as a coronary artery bypass graft in the 1970s. Development of new pharmacologic antispasmodic agents and minimally traumatic harvesting techniques has led to a revival of the use of the radial artery in coronary artery bypass surgery. Usually the main reasons for the spasm are thermal injury(More)
OBJECTIVE Bleeding tendency of paediatric patients with congenital heart disease has been well recognized. The underlying pathologies of this bleeding tendency have been studied extensively and many causes were identified. Among these causes, we aimed to find the frequency of acquired von Willebrand's disease (AvWD) in children with congenital heart(More)
Double-chambered right ventricle is a rare heart defect causing right ventricular outflow tract (RVOT) obstruction. In this malformation, the right ventricle is divided into two chambers by a fibromuscular band. A 12-year old female patient who had undergone repair of a ventricular septal defect at 5 months old was admitted to our hospital with complaints(More)
OBJECTIVE As a highly rare congenital defect, cor triatriatum sinister represents only 0.1% of congenital cardiac anomalies. Depending on the degree of obstruction and the accompanying symptoms, cor triatriatum can be diagnosed at any age. This case series described 5 patients with cor triatriatum sinister who underwent operation. METHODS Five patients(More)
