In the past decade, the face of surgical coronary revascularization has been changed by a number of advances, most notably the development of minimally invasive techniques, including minimally invasive direct coronary artery bypass (MIDCAB), off-pump coronary artery bypass (OPCAB), and totally endoscopic, robot-assisted coronary artery bypass grafting (TECAB). Initial attempts to perform cardia...

BACKGROUND This preliminary investigation evaluated the procedures for intraoperative angiography-assisted peripheral vascular revascularization in a teaching hospital. METHODS Between August 2000 and July 2001, intraoperative angiography with or without intervention was applied during surgery for peripheral arterial occlusive disease (PAOD) in 11 patients. Intraoperative angiography was empl...

Purpose: To evaluate outcome of interventional and surgical treatment in infrainguinal bypass occlusion and to identify predictive factors affecting therapeutic success. Material and Methods: Over a period of three years 96 patients with infrainguinal bypass occlusion were included in this retrospective study. 52 patients were treated by catheter-directed thrombolysis and 44 patients by reconst...

IWATSUKI, N. AMAHA, K. and KoGA, Y. Biphasic Change in Human Peripheral Vascular Resistance Produced by Carnigen®. Tohoku J. exp. Med., 1982, 138 (1), 81-85 The response of the human peripheral vascularesistance (TPR) to carnigen® was examined on 11 patients by measuring arterial pressure change during cardiopulmonary bypass at a constant pump flow. The administration of 2 ml of carnigen into t...

Ultrasonic Doppler studies were made pre- and postoperatively in 22 patients undergoing STA-MCA anastomosis. A quantitative evaluation of the bypass was attempted by determining the STA blood flow velocity and pattern. The STA velocity on the Doppler sonogram was compared with the degree of intracranial vascular filling via anastomotic channels and the STA diameter on angiogram. The STA velocit...

The aortic bifurcation and iliac vessels are common sites of atherosclerotic occlusive disease causing the clinical expression known as "Leriche's syndrome". An aortobifemoral bypass grafting in the setting of a septic groin remains a significant challenge to vascular surgeons. We present a 65-year-old male with complete occlusion of the distal aorta and iliac arteries; he had undergone a left ...

Aortic coarctation is a congenital vascular lesion, usually diagnosed and corrected in childhood or early adulthood. Most of the untreated patients with aortic die before age 50 years. Coarctation cardiac lesions complex clinical situation that necessitates surgical treatment different pathologies strategies.
 In this, study we report two-staged severe stenosis consist valve replacement ao...

-Vein graft intimal hyperplasia, due to smooth muscle cell (SMC) proliferation, remains a limiting factor in long-term vein graft patency. Increased superoxide production regulates SMC mitogenesis and contributes to reduced NO bioactivity in systemic models of vascular disease. We compared superoxide production in experimental venous bypass grafts with ungrafted veins and determined its enzymat...

Preventing amputations in persons with lower extremity complications of diabetes is a complex endeavor, particularly in those with concomitant ischemia and tissue loss. Fluorescence angiography (Novadaq SPY system) may provide a tool for objective evaluations of tissue viability in the diabetic foot, which is an important indicator of the ability of the diabetic ulcer to heal adequately. The SP...
