Application of new biological grafts for small caliber vascular prosthesis.

Abstract

Two types of new biological graft, that is heparinized canine and bioflow bovine, with either conventional suture anastomosis or laser anastomosis were evaluated experimentally and clinically. These 32 grafts anastomosed to canine femoral and carotid arteries were all patent except early one graft occluded for 2 years. The 38 grafts implanted in patient with occlusive arterial diseases and chronic renal failure were 92% (25/28) patency rate for one year postoperative follow-up.
Especially the heparinized grafts anastomosed by laser were the best results with 100% patency without anastomotic intimal hyperplasia.
