Abstract Microvascular anastomosis is a critical step for limb replantation and microsurgical procedures, minimizing the anastomosis time to re-establish blood flow as early as possible is essential for tissue survival and functional restoration. Although the conventional interrupted suture remains the gold standard of microvascular anastomosis, it is time consuming, and its success rate highly depends upon the surgeon’s skill. Furthermore, it places a significant burden on surgeons when multiple and/or extremely small diameter anastomosis are required. That is why many new techniques are introduced for end-to-end microvascular anastomosis all have been advocated for decreasing the anastomosis time yet maintain high patency rates. In our Study we used open-loop technique; our sample size included 40 femoral artery anastomosis of 20 rats divided into two groups; Conventional Interrupted Suture and Open-loop technique. Regarding the anastomosis time, the Open-Loop Technique’s time (22.40 ± 4.48 minutes) is shorter than time of the Conventional Interrupted Suture (24.50 ± 2.04 minutes). Regarding Patency rate, our results showed no significant difference in patency at 5 minutes or at 15 minutes post anastomosis in open-loop technique. Regarding the Anastomotic leakage, we had 19 anastomosis done by conventional interrupted technique evaluated as Grade II and only 1 anastomosis evaluated as Grade III, in open-loop technique 3 anastomosis evaluated as Grade I, 16 anastomosis Grade II and only 1 evaluated as Grade III. |
