The purpose of this study was to investigate the relationship between the distribution of turbulence intensity and the localization of stenoses inside the venous anastomosis of arteriovenous (A-V) grafts. Turbulent flow measurements were conducted inside an upscaled end-to-side graft model under pulsatile flow condition. The pulsatile flow waveforms had maximum, minimum and mean Reynolds number...

UNLABELLED Patients who underwent local radiotherapy during surgical resection for cholangiocarcinoma are at increased risk of developing extensive thrombosis of splanchnic vessels and secondary biliary cirrhosis on the remnant liver; hence they become liver transplantation candidates. In these recipients, adequate graft inflow cannot be provided by conventional liver transplantation procedures...

BACKGROUND The aim of the study was to report the detailed surgical techniques of living donor liver transplantation (LDLT) in patients with Budd-Chiari syndrome (BCS). METHODS Demographic and surgical techniques characteristics of 39 patients with BCS who underwent LDLT were retrospectively reviewed. Thirty-two of them had native vena cava inferior (VCI) preservation and 6 had retrohepatic V...

Methods A 66-year-old man was admitted to our hospital on November 11, 2012. He had a painful, pulseless, and cold below-knee in right lower extremity. He had previous right cross-over composite sequential femoropopliteal bypass. Angiography showed acute occlusion of cross-over composite femoro-popliteal bypass graft and stent graft used in treatment of pseudoaneurysm developing in popliteal an...

OBJECTIVE Despite the theoretical favourable hemodynamic advantage of end-to-end anastomosis (ETE), femoropopliteal bypasses with distal ETE and end-to-side anastomosis (ETS) have comparable clinical patencies. We therefore studied the effects of different in vivo anastomotic configurations on hemodynamics in geometrically realistic ETE and ETS in vitro flow models to explain this phenomenon. ...

To-and-fro pattern in pulse Doppler wave form has been considered a sign of flow competition at the coronary anastomosis. However, this flow pattern is not sufficient to judge whether there is no construction errors in the anastomosis itself. We report a usefulness of the high-frequency ultralinear transducer when used with pulse Doppler because it allows the visualization of the shapes of the ...

Coronary artery bypass graft (CABG) intervention, particularly anastomosis site intervention, is challenging for interventional cardiologists. A paclitaxel-eluting balloon catheter (SeQuent Please) is a recently-introduced device capable of delivering paclitaxel homogeneously into the targeted vessel wall. We herein report our experience with two cases. In the first case, coronary angiography s...

Park and Kim report the case of a 35-year-old man with a bilateral aneurysm of the extracranial carotid artery treated with resection/great saphenous vein grafting in a staged fashion. The aneurysm of the right carotid artery was correctly treated first, as it was larger and contained a larger amount of intraluminal thrombus than the right one. Access to the aneurysms was gained through a curvi...

In liver transplantation, a side-to-side anastomosis is one of the commonly performed techniques inferior vena cava reconstruction. The authors report case an application endoscopic vascular linear stapler for caval during deceased-donor transplantation. back table procedure was in standard fashion anastomosis. introduced temporary clamping recipient’s and created without problems. Suturing res...

The Food and Drug Administration (FDA) Circulatory System Devices Advisory Panel was asked to make recommendations on the PAS-Port Proximal Anastomosis System (Cardica, Inc), a device intended to create an end-toside anastomosis between the aorta and autologous vein graft during coronary artery bypass graft surgery. Advisory panels make nonbinding recommendations to the FDA. Classically, corona...
