内容記述(抄録等)We investigated differences of anastomotic intimal hyperplasia betwveen cobra-head (C group) and straight (S group) forms at the distal end-to-side anastomosis. Beagle dogs were anesthetized and abdominal aortas were incised equidistant between two clamps. The 6mm PTFE grafts with 5cm in length were inserted into the incised aorta by standard vascular techniques. The proximal anastomosis was performed in the end-to-end fashion and the distal anastomosis in the end-to-side fashion. Animals were divided into two groups; one with cobra-head form (n= 5) and the other with straight form in cu end of the graft. All animals were fed a diet of 2.5% cholesterol added to commercial dog chow. Three months later, abdominal aortography was carried out and the animals were then sacrificed. The anastomosed grafts were examined macroscopically and by light-microscopy. The blood flow distribution at the distal anastomosis was measured immediately and three months after surgery. Patency rare was 75% (3/4) in the S group and 80% (4/5) in the C group. Though there was no significant difference in the rate of the distal blood flow (DBF) to porximal blood flow (PDF) at the distal anastomosis between both groups. The DBF in the S goup tended to be greater than that in the C goup. In addition, the anastomotic intimal hyperplasia in the distal anastomosis with the DBF>PBF tended to be smaller than with DBF≦PEF. The distal anastomotic intimal hyperplasia remarkably occurred in the host artery of the toe and in the graft of the heel. We suggest that, in the distal end-to-side anstomosis, anastomotic intimal hyperplasia in the straight form of the cut-end of the graft is smaller than that in the cobra-head form.
