Microsurgery is the procedure of choice for vascular microanastamoses. The objective of this study was to compare two types of suture techniques: classic interrupted suture anastomoses, commonly used for vascular anastamoses in microsurgery, and another technique using horizontal mattress sutures, rarely evaluated in this type of surgery. Twenty albino Wistar rats were operated (average weight: 250 - 300 gr.) under general anaesthesia. A transverse section of the femoral artery was performed and immediately followed by an anastamoses. The animals were placed into two groups of ten. The classic 6 interrupted suture anastomoses technique was performed in group A (n = 10) and another technique using 3 horizontal mattress sutures was performed in group B (n = 10). The patency was checked immediately following anastomoses and at the end of the first hour postanastomoses (for both techniques were always 100% in both times), and so was checked the presence of bleeding (only one case in group B was reported immediately following the anastomoses). The mean anastomoses time for the group B, 15 minutes approximately, was shorter than that for the group A, 21 minutes approximately, and the difference was statistically significant (p < 0.0001).
