We had found that a compound graft made of a non-woven polypropylene sheet enforced by a tetron mesh layer had given rise to better tissure healing comparing with usual synthetic vascular grafts.
In this report the results of canine carotid artery replacement using the new type of compound graft supported with monofilament polypropylene suture rings on both ends were presented.
The graft patency rates of 80% at 3 weeks and 42.9% at 12 to 15 weeks after implantation were satisfactory, so it became clear that the supporting ring at suture line was effective.
In order to get better patency of small caliber vascular graft, we should not only study about the graft materials, but also clarify the cause for the trouble of suture lines and consider how to cope with the situation.
