widely used for patients with multivessel coronary artery disease. The post-operative patency of the bypass graft is important to predict the clinical outcome (1-3). Postoperative myocardial infarction is a rare, but potentially severe complication after CABG. So, the early recognition of the failure of a bypass graft on the early postoperative imaging is necessary to evaluate the quality of th...

Meticulous preoperative volumetry of the partial liver graft is essential for both assessing the postoperative graft function and to ensure the donor safety in the field of living donor liver transplantation (LDLT). We herein report the case of a 53-year-old patient who underwent LDLT for hepatitis C virusinfected liver cirrhosis complicated with hepatocellular carcinoma. Preoperative 3D images...

A76-year-old woman who had a coronary artery bypass using a sequential saphenous vein graft to the diagonal branch and the left anterior descending artery (LAD) remained free of chest pain for 22 years. She was recently diagnosed with critical aortic valve stenosis. Cardiac catheterization showed the sequential saphenous vein graft was patent. The size of the graft was remodeled according to th...

A new methodology for simulating the flow field inside an arteriovenous (AV) graft to vein anastomoses by the adaptive neuro fuzzy inference system (ANFIS) is presented in this study. For determining the optimal AV graft angle, an ANFIS-based model of neuro fuzzy-graft-vein (NF-GVEIN) is proposed. Therefore engineering design of the graft can be supported. The advantage of this neuro-fuzzy hybr...

Arteriovenous grafts (AVGs) for hemodialysis have a high failure rate, often due to the development of stenosis at the graft-to-vein anastomosis. Angioplasty (PTA) has been used for over two decades to treat AVG stenosis, with good technical success but limited AVG patency. Results of a prospective multi-center randomized trial, comparing stent graft to PTA in AVGs, has demonstrated superior ac...

BACKGROUND Postoperatively, signal changes of the reconstructed anterior cruciate ligament (ACL) graft on magnetic resonance imaging (MRI) images commonly occurs, which may be a cause for concern. The signal intensity changes are usually expressed by signal/noise quotient (SNQ) value, representing graft maturity. To date, little is known about the factors influencing the SNQ value of the recons...

P ercutaneous transluminal angioplasty is an accepted treatment for stenoses of bypass graft& and for total coronary artery occlusions.3-5 It follows that the same treatment would also be appropriate for total occlusions of saphenous aortocoronary bypass grafts. This report describes our clinical experience with attempted dilatation of totally occluded saphenous bypass grafts. Of the 2,679 cons...

Hepatic venous outflow obstruction following liver transplantation is rare but disastrous. Here we described a 14-year-old boy who underwent a split right lobe liver transplantation with modified (side-to-side) piggyback technique which resulted in hepatic venous outflow obstruction. When the liver graft was lifted up, the outflow drainage returned to normal but when it was placed back into the...
