OBJECTIVE To evaluate the changes in cerebral blood flow during awake off-pump coronary artery bypass grafting and compare with the changes during off-pump coronary artery bypass grafting under general anesthesia, using continuous monitoring of regional cerebral oxygen saturation. METHODS The study population comprised 3 groups of patients who had undergone off-pump coronary artery bypass gra...

Introduction: This study was to explore the indications, surgical method, and postoperative treatment of orthotopic liver transplantation (OLT) after hepatic artery (HA) reconstruction with an iliac interposition graft. Methods: This study analyzed in-hospital and follow-up outcomes of 34 Chinese patients: 17 who received conventional OLT (“non-bypass” group) and 17 who received OLT with hepati...

background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...

The object of this study was to analyze the pathology of collateral vessels newly induced by indirect bypass surgery for moyamoya disease (MMD). An autopsy analysis was conducted on a 39-year-old woman with MMD who had died of a brainstem infarction. The patient had undergone bilateral indirect bypass surgeries 22 years earlier. Sufficient revascularization via bilateral external carotid arteri...

OBJECTIVE Deep hypothermic circulatory arrest for neonatal heart surgery poses the risk of brain damage. Several studies suggest that pH-stat management during cardiopulmonary bypass improves neurologic outcome compared with alpha-stat management. This study compared neurologic outcome in a survival piglet model of deep hypothermic circulatory arrest between alpha-stat and pH-stat cardiopulmona...

OBJECT Revascularization is an important component of treatment for complex aneurysms that require parent vessel occlusion, skull base tumors that involve major vessels, and certain ischemic diseases. In this study, the authors examined the microsurgical anatomy of cerebral revascularization in the anterior circulation by demonstrating various procedures for bypass surgery. METHODS Twenty-fiv...

Poor quality or inadequate length of venous and mammary conduits, or both, a severely calcified or atherosclerotic aorta, or diffuse coronary atherosclerosis are situations cardiovascular surgeons will be facing with increasing frequency. These conditions are more common to the increasing number of patients requiring reoperation for advancing disease and to the growing number of older patients ...

According to expansion of dialysis-dependent population, more than half of patients with critical ischemic limbs are dialysis-dependent in Japan. Although patients with end-staged renal disease are well-known as poor life prognosis, well-managed dialysis patients in Japan can survive much longer compared to dialysis patients in the United States and Europe. Therefore, some dialysis patients can...

PURPOSE To examine the feasibility and clinical outcome of a novel, minimally invasive technique for harvesting the great saphenous vein (GSV) for use in peripheral arterial bypass surgery. METHODS Between May 2001 through March 2003, 27 patients (15 men; mean age 71+/-10 years) underwent extremity bypass procedures for limb salvage (88%) or disabling claudication (12%) using the inversion te...
