Objective To report the anatomy basis and clinical application of the flap based on the perforator of plantar arch.Methods From December 2013 to June 2016,25 cadaveric feet which were injected with a mixture of red gelatin were used to observe:the origins,courses,branches,distributions of the dorsal perforators flap based on the plantar arch;the anastomoses between the back perforators of plantar arch and rete arteriosum of dorsale pedis.Based on the anatomy research,11 cases with soft tissue defect at forefoot were treated with the perforator flaps.Results 11 flaps survived completely with primary healing.The flaps were followed up for 2-36 months with good match of texture and color.Conclusions The flap based on the perforator of plantar arch has constant and rich blood supply.The technique is easily performed and can be used as an optional flap without major vessel for defect at forefoot.%目的 探讨足底动脉弓足背穿支皮瓣解剖学基础和临床疗效.方法 根据25侧动脉灌注红色乳胶的成人足标本,研究足底动脉弓足背穿支皮瓣供区穿支血管的起源、走行、分支、分布及足底动脉弓足背穿支与足背动脉网吻合等解剖特点.并于临床应用足底动脉弓足背穿支皮瓣修复足前部缺损创面11例.结果 术后11例皮瓣全部成活,创面一期愈合,随访2～36个月,皮瓣质地优良、色泽接近正常,外观较好.结论 足底动脉弓足背穿支皮瓣解剖位置恒定、血液供应良好、手术方法简单,是修复足前部软组织缺损的非主干血管蒂皮瓣供区的补充术式.
