OBJECTIVE To verify the effect of location and severity of stenosis of the target coronary artery (TCA) on mid-term patency of aorta-anastomosed vs. internal thoracic artery (ITA)-anastomosed radial artery (RA) graft. METHODS During a 3-year period 228 consecutive patients received an RA graft at our institution. In 131 cases the RA was anastomosed to the aorta whereas in 97 the proximal anas...

INTRODUCTION Treatment of coronary artery involvement in Takayasu's arteritis is challenging. Coronary artery bypass grafting may be required. The use of saphenous vein grafts is recommended because of possible inflammatory involvement of the internal thoracic arteries. However, inserting the proximal anastomosis on inflamed aortic tissue may give rise to stenosis. Only a few cases of inserting...

OBJECTIVE This study was designed to evaluate the serial haemodynamic changes during coronary artery anastomoses using two deep pericardial stay sutures and octopus tissue stabilizer in patients undergoing initial experiences of off-pump coronary artery bypass graft surgery (OPCAB) using continuous cardiac output and mixed venous oxygen saturation (SvO(2)) monitoring. METHODS With IRB approva...

OBJECTIVE To describe a totally laparoscopic technique for aortobifemoral bypass to treat aortoiliac atheromatous occlusive disease. DESIGN A feasibility study. SETTING A university teaching hospital. SUBJECTS Six piglets weighing between 70 and 80 kg were submitted to a totally laparoscopic retroperitoneal aortobifemoral bypass, performed through six trocar sites, with abdominal suspensi...

We describe a patient who underwent off-pump coronary artery bypass graft surgery performed with an aortic connector. The patient developed a malignant deep sternal wound infection that subsequently led to an aortic pseudoaneurysm at the site of proximal anastomosis.

The status of the native coronary arteries at necropsy in the vicinity of the coronary anastomoses of saphenous vein aortocoronary bypass grafts in 20 patients with severe coronary heart disease is presented. Of the 37 graft systems (graft plus coronary artery into which graft inserted) analyzed, the lumina of 44% of the native coronary arteries within the first 2 cm distal to the anastomoses w...

Auxiliary partial heterotopic liver transplantation (APHLT) with portal vein arterialization is a valuable procedure to be considered in the treatment of patients with acute liver failure and metabolic liver diseases. The aim of this study was to develop a new rat model of APHLT with liver dual arterial blood supply (LDABS). A total of 20 rats were used. The donor liver was resected, and the ce...

Purpose: The clinical advantages of end-to-end (ETE) anastomosis have not been clear despite its biomechanical advantage over end-to-side (ETS) anastomosis. We compared the histomorphometric features of intimal remodeling after ETE and ETS anastomosis in a rabbit aortic bypass model. Methods: Thirty-two bypass operations, 16 with ETS and 16 with ETE anastomoses, were performed using aortic allo...

BACKGROUND Facial nerve is easy to be damaged, and there are many reconstructive methods for facial nerve reconstructive, such as facial nerve end to end anastomosis, the great auricular nerve graft, the sural nerve graft, or hypoglossal-facial nerve anastomosis. However, there is still little study about great auricular-facial nerve neurorrhaphy. The aim of the present study was to identify th...
