A New Technique For Microvascular Anastomosis Eversion With 3 Horizontal Mattress Sutures

Abstract: In our experimental study of a new microvascular anastomosis technique, we divided 30 Wistar albino rats into 2 groups.We performed the classic interrupted suture anastomosis techniquein group 1 (n
15) and our new technique, using 3 horizontalmattress sutures, in group 2 (n
15). We checked patency immediately following anastomosis, at the end of the first hour, and at theend of the third week postanastomosis.While the patency rates for both techniques were 100% at the endof the first hour, the respective values were 100% and 93.4% by theend of the third week. Using light microscopy, lumen patency,intimal and medial damage, inflammation, and granulation wereevaluated histopathologically.The mean anastomosis time for the experimental group (15 minutes)was shorter than that for the classic group (mean 21 minutes), and thedifference was statistically significant (P 0.01), while the differencebetween the patency rates was not significant (P
0.05). Therefore,provided that the incisions are made correctly, our microvascularanastomosis technique using 3 horizontal mattress sutures can be usedin experimental and clinical studies.Key Words: microsurgery, microvascular surgery, vesselanastomosis, vascular anastomosis method, 3 horizontal mattresssutures
