穿支皮瓣是临床广泛应用的组织缺损修复技术,但因穿支血管的管径细小,供区面积有限,使得穿支皮瓣在体表大面积缺损修复中的应用受到限制。本文从穿支皮瓣血管解剖、血供特点,以及增加皮瓣血运和促进组织血管化的相关治疗策略出发,对扩展穿支皮瓣血供范围的基础和临床研究进展进行综述。

Perforator flap has enjoyed a wide popularity in tissue repair, however, its application on reconstruction of massive superficial defects has been impeded by the small diameter of perforator artery and the limited volume of usable flap. After an extensive review of literatures published recently,this article delineated an up-to-date progress in basic and clinical research on expansion of perforator flap vascular supply, including the perspective of vascular anatomy and flow characteristics of perforator flap as well as relevant therapeutic strategies to increase flap blood supply and promote tissue vascularization.
