This study was planned to assess the relationship of perioperative glycemic control to the subsequent risk of infectious complications and to compare early clinical outcomes of coronary artery bypass surgery in diabetics with nondiabetics in a single center. A total of 1090 adults who underwent coronary artery surgery in a five year period were included in(More)
BACKGROUND Open heart surgery still involving major bleeding continues to be a major challenge after cardiac surgery and is also a significant cause of morbidity and mortality. Most hemostatic factors are intercorrelated with postoperative bleeding, and fibrinogen seems the most fundamental hemostatic risk factor for open heart surgery. METHODS The study(More)
OBJECTIVE Arteriovenous fistula (AVF) in patients undergoing hemodialysis (HD) may cause coronary left internal mammary artery (IMA) steal. This phenomenon was demonstrated by few prospective studies with limited number of patients and case reports. We aimed to demonstrate with a relatively larger patient population that the AVF may cause ipsilateral IMA(More)
[3], and echocardiography [1] have been used for the detection of coronary artery anatomic variations in tetralogy of Fallot (TOF). To our knowledge, this is the first report of multidetector computed tomography (MDCT) angiography of the coronary arteries in a small infant with TOF [4]. MDCT was performed in a 3-year-old with TOF because of suspected(More)
BACKGROUND Postoperative atrial fibrillation (AF) plays a major role in the determination of hemodynamic deterioration and can be associated with cardiovascular events after coronary artery surgery. Elevated interleukin (IL)-6 and C-reactive protein (CRP) levels in patients with AF suggest a role of inflammation in the pathogenesis of AF. We conducted a(More)
BACKGROUND Clinical procedures involving extracorporeal blood circulation are potentially complicated by the interaction of various blood systems with foreign surfaces. In cardiopulmonary bypass, exposure of blood to synthetic surfaces generally leads to activation of cellular and humoral blood systems with activation of complement cascade. This reaction(More)
OBJECTIVE To evaluate the roles of surface electrocardiogram (ECG) and transthoracic echocardiography (ECHO) for prediction of atrial fibrillation (AF) after coronary artery bypass grafting (CABG). METHODS This study was conducted from 2002-2004 at the Cardiovascular Department of Hacettepe University, Ankara, Turkey. Seventy consecutive patients were(More)
A pseudoaneurysm is defined as an aneurysmatic sac surrounded byfibrous tissue instead of other vascular layers such as the muscular one. It is a rare incident in infants especially in the brachial artery. Blunt trauma and vascular access attempts are the most common etiologic factors. We present two infants with brachial artery pseudoaneurysm in the(More)
Xanthomas are benign soft-tissue lesions commonly occurring on the skin, subcutis, or tendon sheaths of patients. The lung and thoracic cavity is a rare location for xanthomas. We present a 39-year-old woman who was admitted to our hospital with complaints of dyspnea, cough, and chest pain. She had a prior diagnosis of type II familial hypercholesterolemia.(More)
