Abstract:
There is no doubt that the introduction of synthetic materials was the prerequisite for success of vascular surgery. Biological inertness, durability, eases of sterilization and modeling of synthetic vascular grafts contributed to their widespread use as in aortic and great vessels. However, analysis of the accumulated clinical experience in using of synthetic grafts showed that fascination with them was gradually replaced by cautious attitude, and sometimes by refusing, because in the presence of well-known advantages, synthetic grafts are prone to thrombosis and the development of infection.

Abstract:
Our purpose was to evaluate whether or not and when phenotypic modulation of smooth muscle cells (SMCs) in hybrid vascular prostheses preincorporated with SMCs occurs upon implantation. Two types of hybrid vascular grafts incorporated with vascular cells derived from canine jugular veins were prepared: grafts containing a collagen gel layer covered with an endothelial monolayer at the luminal surface (Model I graft) and those containing an endothelial monolayer and SMC multilayer (Model II graft). They were bilaterally implanted into carotid arteries of the same dogs from which the cells had b

Abstract:
Surface modification of polymer vascular matrices is a promising development for preventing vascular graft thrombosis, improving long-term patency and accelerating remodeling. Objective: to study the outcomes of long-term patency of PHBV/PCL/GFmix grafts with iloprost (Ilo) and heparin (Hep) implanted into the carotid artery of sheep. Materials and methods. Matrices 04 mm were fabricated by electrospinning from a polymer composition of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(s-caprolactone) (PCL) with incorporation of endothelial growth factor (VEGF), basic fibroblast grow

Abstract:
Bionic grafts hold great promise for directing tissue regeneration. In vascular tissue engineering, although a large number of synthetic grafts have been constructed, these substitutes only partially recapitulated the tri-layered structure of native arteries. Synthetic polymers such as poly(l-lactide-co-ε-caprolactone) (PLCL) possess good biocompatibility, controllable degradation, remarkable processability, and sufficient mechanical strength. These properties of PLCL show great promise for fabricating synthetic vascular substitutes. Here, tri-layered PLCL vascular grafts (TVGs) composed of a

Abstract:
The means for developing synthetic vascular grafts to replace blood vessels is increasing extensively because of the limited supply of autologous vessels. Synthetic polymers as the alternatives still suffer from restenosis and thrombus formation. Natural polymers, on the other hand, are commonly biocompatible and biodegradable, compliment the synthetic ones. Blending, grafting and coating of natural polymers have been proposed to improve surface properties of synthetic polymers. Gelatin is a promising candidate to help improving synthetic vascular grafts surface owing to its ability to promote

Vascular grafts are significantly needed in peripheral vascular surgery; however, small diameter grafts are not always available, and synthetic grafts perform poorly because of acute thrombosis and neointimal proliferation after implantation.

Abstract:
Thrombosis of synthetic grafts commonly used in cardiovascular surgery is a major complication. We examined whether pretreatment of the graft with heparin reduces the risk of early thrombosis. A circuit was assembled to compare two pairs of shunts simultaneously in the same animal. The study shunts were pretreated with heparin. After 2 hours of circulation, clot formation was evaluated by image analysis techniques. The pretreated grafts had fewer blood clots adhered to the surface by direct visual inspection. The image analysis showed 5 vs. 39 clots, 0.01% vs. 1.8% clotted area, and 62 vs. 563
