title: Microvascular anastomosis with absorbable and nonabsorbable sutures--a comparative study in rats.
abstract: Polyglycolic acid, polypropylene, and nylon sutures were used to anastomose the aortas of 40 rats. Comparative studies of the healing process at the suture sites were performed. The long-term observations, by means of light and scanning electron microscopy, revealed that the regeneration of endothelium was more rapid and the endothelium had a smoother surface in the aortas that received the polyglycolic acid sutures than in the aortas receiving polypropylene or nylon sutures because the polyglycolic acid sutures were absorbed after 6 weeks. It was concluded that polyglycolic acid suture material may be more desirable than nonabsorbable suture material in microvascular anastomoses.
