BACKGROUND There are many studies in the literature combining vein grafts with cell cultures, muscle, tendon, and nerve tissues, but none of them could replace isolated nerve grafts for nerve repair in clinical settings. There are studies in the literature indicating that adipose tissue derived stromal vascular fraction (SVF) enhances peripheral nerve healing. Considering these facts, an experi...

Objective. Emerging evidence suggests an important role for mast cells in vein graft failure. This study addressed the hypothesis that perivascular mast cells regulate in situ vascular inflammatory and proliferative responses and subsequent vein graft neointimal lesion formation, using an optimized local mast cell reconstitution method. Methods and Results. Neointimal hyperplasia was induced by...

BACKGROUND Optimization of the saphenous vein for myocardial revascularization. OBJECTIVE To present the no-touch technique of the saphenous vein preparation. This technique consists of harvesting the vein with a pedicle of surrounding tissue, which protects the vein from spasms, obviating the need for distension. METHODS A prospective, randomized study with 156 patients who underwent arter...

BACKGROUND More than 50% of aortocoronary saphenous vein grafts are occluded 10 years after surgery. Intimal hyperplasia is the initial critical step in the progression toward occlusion. Internal mammary veins, which are physiologically prone to less hydrostatic pressure, may undergo an accelerated progression to intimal hyperplasia and thus be suitable for investigation of the mechanisms of ao...

Percutaneous coronary intervention of grafts vessel is more challenging due to a higher incidence of periprocedural distal micro-emobilization and myocardial infarction. Percutaneous coronary intervention current guidelines advocate usage of distal embolic protection devices, especially in patients with a large thrombus burden, undergoing percutaneous intervention for vein graft disease. We pre...

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...
