Introduction of loop sutures in microsurgical telescoping anastomosis

We have designed a loop suture technique for use in microsurgical telescoping (sleeve) anastomosis to prevent problems from the free floating inserted vessel stump. The patency rate of rat femoral arteries repaired with this technique was 95% and that of interpositional vein grafts, in which both the proximal and distal anastomoses were completed with the same sleeve technique, was 81.0%.
