The end-to-end anastomosis by simple interrupted suture was considered to the most reliable method in microvascular anastomosis. But recently, the methods which show less damage to endothelium, less postoperative thrombosis, high patency rate, simple and rapid method are invented, such as sleeve anastomosis, cuff method, anastomosis by continuous suture, tissue adhesive, ring anastomotic device, etc.
In this experimental studies, a new anastomotic method was designed such as that the proximal vessel was telescoped to the distal vascular lumen by two tagging suture (0°, 180°), and tissue adhesive (Butyl-2-Cyanoacrylate) was applied to contact area between the end of distal vessel and the adventitia of proximal vessel.
The anastomoses by this method were done on femoral arteries of rat, and compared to conventional end-to-end anastomosis method, and observed following postoperative 2 days, 1 week, 2 weeks, and 3 weeks.
The results are followings:
1. Easy method
2. Less consumption time(mean 7 min 20 sec)
3. High patency rate (overall 92.5%)
4. No aneurysm formation
5. Complete neointima was recovered within 1 week.
6. Foreign body reaction was confined only to adventitia.
