OBJECTIVES Composite arterial grafting is a surgical technique for arterial myocardial revascularization, in which free arterial conduits are proximally anastomosed end-to-side to an intact internal thoracic artery (ITA). This report describes technical aspects and results of composite grafting using bilateral skeletonized ITAs. METHODS From April 1996 to February 1999, 1057 patients underwen...

One hundred and sixty five cases of various types of transposition complexes were studied. Based on this and on recent studies of the embryology of the conotruncus, the following observations were made. Regardless of their relations with the ventricles, the semilunar valves may show d-transposition or i-transposition. In the situs solitus heart, the d-type of semilunar transposition is found in...

BACKGROUND AND PURPOSE The safety of placing multiple overlapped endoluminal flow diverters remains unclear because small eloquent branch arteries theoretically could become occluded by these devices. We placed single and multiple flow diverters over small branch arteries in rabbit aortas to determine the incidence of branch artery occlusion. MATERIALS AND METHODS Flow diverters (PED) were pl...

Little is known of the course and distribution of blood vessels supplying and draining the hippozampus. Such information could be of value in designing and evaluating lesion and ablation experiments and may reflect spatial properties of neurons. This study mapped the distribution of major arteries and veins of the rat hippocampal formation. Arteries and veins of adult female Wistar rats anesthe...

OBJECTIVES Arterial remodeling has been suggested as the predominant factor in restenosis. However, the time course and morphometric factors that determine whether remodeling occurs remain unclear. We hypothesized that arterial remodeling does not occur in all arteries following balloon injury and is dependent on neoadventitial formation. METHODS Using single (SI) and double (DI) balloon inju...

aortic dissection begins with the formation of a tear in the aortic intima, and it directly exposes an underlying diseased medial layer to the driving force of the intraluminal blood. this blood penetrates the diseased medial layer and cleaves the media longitudinally, thereby dissecting the aortic wall. herein, we report the case of a 38-year-old woman, who presented with chest pain and dyspne...

OBJECTIVE To assess the feasibility and safety of duct-to-duct biliary anastomosis for living donor liver transplantation (LDLT) utilizing the right lobe. SUMMARY BACKGROUND DATA Biliary tract complications remain one of the most serious problems after liver transplantation. Roux-en-Y hepaticojejunostomy has been a standard procedure for biliary reconstruction in LDLT with a partial hepatic g...

Cystic adventitial disease is a rare disorder that occurs in peripheral arteries. Calf claudication caused by compression of the popliteal artery is a typical presentation of this disease. This is a report of two cases of occluded popliteal artery decompression by percutaneous ultrasound-guided cyst aspiration. In both cases, decompression of the artery was achieved with a significant decrease ...
