Vascular arastomoses using absorbable suture materials Exprimental study and clinical application

Abstract

Synthetic vascular prostheses were implanted in the aorta of 11 mongrel dogs using absorbable suture.; polyglycolic acid (PGA) and polydioxanon (PDS). In the follow up period up to 24 months after operation, there were no evidence of suture line disruptions nor aneurysm fomations. Histologic examination and tensile strength test suggest strength of anastomoses depends mainly on the connection between adventitia and outer capsule rather than on the sutures. Application of absorbable suture in the vascular reconstruction using autoveingrafts were done in 30 bypasses without any complication. The observed good healing support the use of absorbable sutures in vascular surgery dealing with not so severely pahtologic autogenous vessels, and growing vessels.
