Vessel anastomosis is the most critical step in free tissue transfers and replantation surgery. We report on a new microvascular anastomosis technique that uses a metallic circle around the anastomotic circumference. Sutures are first passed inside the circle and tied outside and over the circle so as to stretch open the anastomotic site. By retraction of vessel ends, the circle is totally exteriorized and thus there is no contact with blood. In 48 rats, the external circle method was compared with the conventional technique for constructing end-to-end anastomosis between carotid arteries (1 to 1.2 mm) and femoral veins (1 to 1.5 mm). The external circle method proved to be superior to the conventional end-to-end technique in speed of execution for both arterial and venous anastomoses. Patency rates at the third week were significantly higher in the venous group using the metallic circle (100 percent versus 70.8 percent, p < 0.05). This new method may be applicable in clinical microvascular surgery.
血管吻合术是游离组织移植和再植手术中最关键的步骤。我们报告一种新的微血管吻合技术，该技术在吻合口周围使用一个金属圈。缝线首先穿过圈内，然后在圈外打结并跨过圈，从而撑开吻合部位。通过牵拉血管两端，金属圈完全露出体外，因此不会与血液接触。在48只大鼠中，将外圆法与传统技术进行比较，用于构建颈动脉（1至1.2毫米）和股静脉（1至1.5毫米）之间的端端吻合。结果表明，外圆法在动脉和静脉吻合的执行速度上均优于传统的端端技术。使用金属圈的静脉组在第三周的通畅率显著更高（100%对70.8%，p<0.05）。这种新方法可能适用于临床微血管手术。
