METHODS Between 1992 and 1995, this prospective, randomized, placebo-controlled study examined 120 patients in whom atrial(More)
Among various pharmacological agents used to reduce bleeding after open-heart operations, high-dose aprotinin therapy seems most promising. However, its long-term effects are still obscure; there is almost always possibility of bypass graft occlusions produced by the hypercoagulable state induced by aprotinin in coronary bypass operations. Topical(More)
BACKGROUND Military vascular injuries frequently result from fragment wounds while civilian vascular injuries usually are caused by gunshot wounds. The natural history of untreated major injuries by small low velocity fragments is not well known. This study evaluated the nature of these wounds. METHODS From 1990 to 1995, 40 patients with a delayed(More)
Penetrating injuries to abdomen and especially deep gluteal injuries causes vascular and non vascular injuries which necessitates emergency surgery. Surgical management of the penetrating injuries is very difficult, especially exploration of the gluteal region is very difficult. Management of the injury of iliac artery branches is extremely difficult. Two(More)
Left ventricular (LV) endoaneurysmorrhaphy is a relatively new surgical procedure with excellent results. Forty-five patients underwent surgical repair of LV aneurysm with LV endoaneurysmorrhaphy from 1991 to 1995. The main indication for operation was angina pectoris (71%). Concomitant myocardial revascularization was performed in 97% of the patients. The(More)
OBJECTIVE The aneurysm of the membranous septum (AMS) has often been considered as benign in the minds of many previous investigators. We have analyzed the complications with AMS in adult patients. METHODS Fifty-one cases (20%) of AMS in 254 adult patients with perimembranous ventricular septal defect (VSD) are described. The diagnosis of AMS was based on(More)
Two patients, aged 20 and 21 years, with supravalvular aortic stenosis and aneurysms of the coronary arteries are described. In supravalvular aortic stenosis, dilatation of the sinuses of Valsalva and multiple abnormalities of one or both coronary arteries are common. Aneurysm of coronary artery has not been well recognized as a lesion associated with(More)
OBJECTIVE The results of single clamp and partial clamp techniques were retrospectively compared in elderly patients (>70 years) undergoing coronary artery bypass grafting operation (CABG). METHODS A total of 244 elderly patients undergoing CABG between January 1995 and March 2002 in our center were studied. Single-clamp technique was used in 32 cases(More)
