Background Various techniques have been described for performing microsurgical anastomosis with providing high patency rates. Although the total anastomotic time may not be an issue when dealing with a single set of anastomoses, using a faster technique may save significant amount of time in cases of transferring flaps with shorter critical ischemia time or where multiple anastomoses are required. This study compares the total anastomosis time between four different combinations of commonly used suturing and knot tying techniques. Methods Twenty-four rats were divided into 4 groups. Simple interrupted suture with conventional knot tying technique (SIS-CT) was used in group I, continuous suture technique with conventional knot tying (CST) was used in group II, simple interrupted suture with airborne knot tying technique(SIS-AT) was used in group III, and continuous-interrupted suture with airborne knot tying technique(CIS-AT) was used in group IV for microsurgical anastomosis. Total anastomosis time and patency rates with each technique and samples from anastomotic sites were analyzed. Results The mean time required for microvascular anastomosis of the femoral artery was 1075 s in group I, 799 s in group II, 844 s in group III, and 973 s in group IV. The difference between four groups was statistically significant. The anastomoses in group II and group III were completed in the shortest period of time. Intergroup comparison revealed that the difference between group II and group III was not statistically significant, however, total anastomosis time for completion of the anastomosis was significantly longer for group I, followed by group IV. Thrombosis rates and histological analysis revealed no significant differences among four groups. Conclusion CST and SIS-AT techniques can significantly reduce microsurgical anastomosis time and provide high patency rates. Also, the time needed to complete an anastomosis was significantly shorter for CIS-AT when compared to SIS-CT.
