Use of continuous horizontal mattress suture technique in end-to-side microsurgical anastomosis.
OBJECTIVE
The aim of our study was to improve the new suturing method which increases the success rate of end to side microsurgical anastomosis.


METHODS
Thirty-six Sprague-Dawrey rats were randomly divided into three groups that consist of 12 rats in closed envelope method. The end-to-side microsurgical anastomosis procedures were applied by the same surgeon between left main carotid artey and left external jugular vein. The surgical evaluations were performed with anastomosis duration, leakage evaluation, vessels patency, aneurysm improvement and histological assesment.


RESULTS
End-to-side anastomosis, which was applied with Continuous Horizontal Mattress suture, gave significantly better results in terms of leakage, anastomosis openness, aneurysm and histologic assesment. Also anastomosis duration of Continuous Horizontal suture was significantly faster than Simple Intermittent suture.


CONCLUSIONS
Our study revealed that the Continuous Horizontal Mattress suture technique had the advantages of providing uninterrupted vessel flow in a shorter time, and minimal intraluminal suture material, which increase thrombosis risk. Also 'sac-mouth' effect of Continuous suture technique was prevented by Horizontal Mattress technique.
