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)
BACKGROUND Organ malperfusion is a serious complication of acute type A aortic dissection. Management and outcome of malperfusion has been discussed in this study. METHODS Between November 1994 and May 2003, 118 patients with acute type A aortic dissections were operated. Fifty-seven patients (48.3%) were complicated with organ malperfusion, which is(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)
In this report we describe the surgical treatment of a 27-year-old patient with complete Cantrell's syndrome, i.e. multiple ventricular septal defect, left ventricular diverticulum, dextrorotation of the heart, an anterior diaphragmatic defect, and a midline supraumbilical abdominal wall defect with tetralogy of Fallot. Resection of the diverticulum was(More)
OBJECTIVE The purpose of this study was to evaluate the safety and efficacy of postoperative administration of prophylactic amiodarone in the prevention of new-onset postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting. METHODS In this prospective study 157 patients were randomly divided into two groups: 77 patients(More)
Coronary artery bypass grafting (CABG) in patients with poor left ventricular function remains a surgical challenge and is still controversial. The purposes of this study were to evaluate the effectiveness of CABG in such patients when performed without case selection on the basis of preoperative viability tests and to determine the predictors of(More)
The purpose of our study was to evaluate prospectively the frequency and significance of brain lesions after elective carotid endarterectomy (CAE) and carotid artery stenting (CAS) by using diffusion-weighted magnetic resonance imaging (DW MRI) and then to correlate imaging findings with neuroclinical outcomes. From February 2003 through March 2005, 95(More)
Aneurysms of the left main coronary artery (LMCAA) are extremely uncommon, with an incidence of 0.1%. The main etiologic factor is atherosclerosis. Other causes include connective tissue disorders, trauma, vasculitis, congenital, mycotic, and idiopathic. These dilated sections of coronary artery are not benign pathology because they are subject to spasm,(More)
OBJECTIVES Aortic aneurysm is a serious problem in Behçet's disease, but open surgical therapy carries the risk of recurrent pseudoaneurysm. Here the outcomes of endovascular repair and adjunctive immunosuppressive therapy for aortic disease in Behçet's disease are presented. MATERIALS This was a retrospective study. Between 2002 and 2012, nine patients(More)
