Abstract The utilization of cryopreserved human allografts is a recommended option in the septic vascular surgical field, if autologous graft not available. These grafts are subjected to deep freezing and stored at ? 80 °C until further utilization. goal our investigation was determine effect cryopreservation on structure vessel wall as function storage time, using freshly excised porcine aorti...

Purpose: Most of the grafts used as interposition conduits for middle hepatic vein (MHV) in living donor liver transplantation (LDLT) have been allografts and autografts. Recently, peritoneum has vessel substitutes during surgery. Thus, we performed animal lab tests to assess feasibility graft MHV. Methods: The inferior vena cava was replaced three dogs pigs with autologous peritoneal graft. Af...

Tissue engineering of vascular grafts 187 1 3 Summary Background There is a considerable clinical need for a sufficient prosthetic small-diameter substitute which can compete with autologous vessels. Currently used synthetic materials have a poor performance due to high thrombogeneicity and development of intimal hyperplasia. Tissue engineering is an interesting alternative approach for vascula...

Abstract Polycaprolactone (PCL) is widely applied for the construction of small-diameter tissue-engineered vascular grafts (TEGs) due to its biomechanical properties, slow degradation, and good biocompatibility. In present study TEG based on a tubular scaffold seeded with smooth muscle aortic cells (SMCs) in rat abdominal aorta replacement model was tested. Polyester scaffolds were generated by...

Because there is no 'ideal' method for the complete correction of some of the more complex congenital cardiac abnormalities, a technique of making a composite graft of autologous fascia lata has been developed. Three types of grafts are described, all of them being based on the same general principle. The composite graft comprises a conduit, which serves to enlarge or reconstruct the outflow tr...

BACKGROUND Several methods have been reported for intercalary reconstruction of femoral defects. Of these, free vascularized fibula grafts (FVFG) are preferred because of their durability, bone-healing potential, and tolerance to infection. If the bone tumor invades the femoral vessels, simultaneous vascular reconstruction also becomes necessary and significant technical hurdles make limb salva...

Platelet survival time is frequently shortened in patients with coronary artery disease, and it is one of several factors that might contribute to graft occlusion after saphenous vein coronary artery bypass (CAB). In 35 patients with CAB, average platelet survival (autologous labeling with 51Chromium) was shortened in 20 with one or more saphenous vein grafts occluded and normal in 15 with all ...
