Arterial anastomosis using the telescoping method and an elastomeric adhesive

We experimentally studied a new technique for anastomosis of small arteries which involves the telescoping method and a surgical adhesive with the obj ective of examining its clinical potential. This technique was applied to t he unilateral femoral arteries of 27 mongrel dogs. After division of the ar tery, the distal artery was incised longitudinally, and the proximal end wa s invaginated into the opened artery. One stay suture and the elastomeric a dhesive PUP201 were placed in the anastomotic site. The bursting and tensil e strength and the patency were examined, and a histopathological study was performed at various intervals up to 1 year after the operation. The burst ing strength exceeded 500 mm Hg. The patency rate of the anastomosed arteri es was 100%. The mean percentage of stenosis to diameter of the proximal no rmal lumen was 20% one year after operation. The luminal surface of the ana stomosed line was healed smoothly, and thrombi between the telescoped arter ies were replaced by elastofibrotic union. In conclusion, small arterial an astomosis using the telescoping method and an elastomeric adhesive is easy and safe and provides good patency.
