[Vascular prosthesis made of polyester threads for microsurgery].
The results of experimental and medical application of worked out by the authors synthetic microvascular prosthesis with the internal diameter from 1 to 3 mm. The prostheses were implanted to the abdominal aorta and to the tail vein of rats and also to femoral and carotid arteries of cats for a period of 1 till 15 months. The angiographic and morphologic experiments of blood flow were carried out. The patency of the microprosthesis in the experiments was to 92.7%. The micro-implant adaptation was characterized by complete tissue isolation of a synthetic skeleton with formation of thin and even internal membrane covered with endothelium layer. In fact the possibility of arterial and venous prostheses having a 1-2 mm diameter with synthetic substitutional textile products creates new possibilities for the further development of the microvascular surgery. The microvascular prosthesis was applied to 10 patients in plastic surgery of small circumferential arteries of limbs achieving positive results.
