EXPERIMENTAL STUDY OF SMALL VESSEL ANASTOMOSIS WITH MICROVASCULAR CLIPS / 解放军医学杂志

ABSTRACT

To explore an ideal way of small vessel anastomosis in microsurgery. Anastomosis of both carotid arteries were performed in 20 rabbits. The artery on one side was anastomosed with anastomotic clips,with the contralateral artery,which was anastomosed with sutures,for comparison. The vessels were harvested 1 and 14 days after the operation and were evaluated with operating microscopy, light microscopy and electronic microscopy. The average anastomosis time for suturing was about 15 min, while for clipping was 2～5min. There was no difference in patency between the two techniques. Endothelialization at the anastomotic sites were both completed 14 days postoperatively. However, when anastomotic clips were used, there were no endothelial damage and foreign bodies inside the vessels.This experiment has confirmed that anastomosis with clips provides a very safe and easy way to perform anastomosis and could reduce the incidence of thrombosis.
