Background: Several new techniques have been developed for microvascular repair to reduce the procedure time, such as laser, glue, intravascular stent and precise microvascular anastomotic system. The major reasons for developing these alternative techniques are to reduce the time required to perform an anastomosis, an operation that takes up most of the time in a reconstructive microsurgical procedure, as well as the amount of suture material used, the trauma inflicted, and the likelihood of thrombosis; additionally, the elimination of size discrepancy, the reduction of costs, and the development of a technique that is relatively easy to learn and perform are other factors contributing to the development of these alternative techniques
