Research progress of sutureless microvascular anastomosis
Vascular injury,particularly microvascular injury,is a common type of surgical trauma.Vascular anastomosis is a crucial technique in organ transplantation,trauma repair,and limb replantation with wide applica-tions.Suture anastomosis is considered the golden standard for vascular anastomosis procedures,but its outcome mainly relies on the skills and experiences of the surgeon in dealing with microvessels with a diameter<3 mm.Ad-ditionally,suture anastomosis may cause additional trauma to vessels,especially for microvessels,for which the dam-age is more significant.To alleviate procedural challenges,reduce operation time,and avoid extra intimal damage caused by sutures,sutureless vascular anastomosis techniques have been developed as a supplementary method to su-ture anastomosis and gradually applied for microvascular anastomosis.This article presents a comprehensive review of four primary techniques employed in microvascular anastomosis:adhesive anastomosis,laser-assisted anastomosis,intravascular stent-assisted anastomosis,and vascular coupler anastomosis.The advantages and disadvantages of dif-ferent sutureless vascular anastomosis techniques for microvessels are discussed to provide clinical references and of-fer insights into future research directions.
