Sutureless Microvascular Anastomosis: Literature Review

Traditionally, suturing techniques have been the mainstay for microvascular anastomoses, but owing to its technical difficulty and labour intensity, considerable work has gone into the development of sutureless microvascular anastomoses. In this review, the authors take a brief look at the developments of this technology through the years, with a focus on the more recent developments of laser-assisted vascular anastomoses, the unilink system, vascular closure staples, tissue adhesives, and magnets. Their working principles, with what has been found concerning their advantages and disadvantages are discussed.
