BACKGROUND The radial artery is often used as the second arterial graft for coronary artery bypass grafting. Little is known about the differences in long-term patency between radial free and T grafts. This study was performed to determine long-term radial artery patency over a 15-year period. METHODS AND RESULTS Radial arteries were used as free grafts or T grafts for coronary artery bypass ...

Background The aortic arch is wide, compliant, and mobile. Its flow rate is high and its branches supply an organ, the brain, with no tolerance for ischemia. In this location, an endovascular stent graft is difficult to deliver, difficult to secure, and prone to fatigue fracture, graft erosion, or migration. The only advantage is the opportunity for downstream access to vital arterial branches,...

OBJECTIVE To assess the early results of combined coronary artery bypass graft surgery and carotid endarterectomy. DESIGN Retrospective and ongoing analysis of patients who underwent combined coronary artery bypass graft surgery and carotid endarterectomy. SETTING Cardiothoracic unit in a London teaching hospital. PATIENTS From June 1987 to March 1995, 64 patients were identified. They we...

INTRODUCTION The knowledge of the prevalence of risk factors and comorbidities, as well as the evolution and complications in patients undergoing coronary artery bypass graft allows comparison between institutions and evidence of changes in the profile of patients and postoperative evolution over time. OBJECTIVE To profile (risk factors and comorbidities) and clinical outcome (complications) ...

BACKGROUND Maintaining flow in a newly established high-flow bypass into the intracranial circulation may be threatened by low blood pressure. OBJECTIVE To identify mean arterial blood pressure below which early graft failure may ensue. METHODS Computational fluid dynamic blood flow simulation and Doppler ultrasound-derived velocities were combined to study 12 patients with common carotid-t...

femoropopliteal bypass graft from the groin to the knee to save the lower extremities of patients that have severe arterial disease. The most common cause of early failure of a femoropopliteal bypass graft is usually technical error. Sometimes, extrinsic compression by surrounding structures may result in impediment of blood flow within the graft (1). The femoropopliteal bypass graft can be ent...

background and purpose: ischemic heart diseases (ihd) is getting as the most common and the main causes of heart diseases and mortalities worldwide affecting the quality of life (qol) of the patients. this study was conducted to determine the qol for the patients with ihd referring to medical centers of kashan in 2007. methods: this cross-sectional study was performed on all patients (n =500) r...

the purpose of this study was to investigate the effects of an 8 week period of aerobic interval training and massage therapy on changes in c-reactive protein (crp) level and cardiorespiratory fitness in cardiovascular patients after coronary artery bypass graft. the study population consisted of patients who had undergone a coronary artery bypass graft and at least one month had passed since t...

S ince the introduction by Floyd Loop at the Cleveland Clinic of the internal mammary artery (IMA) as an arterial graft to bypass the left anterior descending artery (LAD), it has been the gold standard conduit for revascularization, principally because it demonstrated its potent survival benefit in the long term follow-up.1 However, patients with multivessel coronary artery disease (CAD) under...
