摘要:

目的 提供第1掌骨背桡侧岛状皮瓣的应用解剖依据。 方法 解剖 20具防腐固定成人手标本,观测第1掌背桡侧皮支血管链的起源、外径、长度及吻合。1例新鲜成年手标本动脉造影。  结果 在拇长展肌腱止点深面可见一条粗大皮支起始,39侧来源自桡动脉浅支,1侧来源于桡动脉主干。该皮支主干沿拇短伸肌腱桡侧向远端走行,相距2 mm。在掌指关节平面,与指掌侧动脉穿支吻合。  结论 以第1掌骨背桡侧该皮支为轴心血管设计轴线,切取岛状皮瓣修复手部皮肤软组织缺损在解剖上具有可行性。

Abstract:

Objective To provide anatomic basis for the first dorsoradial metacarpal  island flap. Methods The origin, diameter, length and anastomosis of the cutaneous branches from superficial radial artery were explored and observed . Arteriography was used in one side of a fresh adult hand specimen to observe the artery. Results A large cutaneous branch originated from the superficial radial artery  beneath the insertion of the abducter pollicis longus in 39 sides of fixed adult hand specimens,and originated from the radial artery in one side. This large cutaneous branch was located on the radial side of the extensor pollicis brevis tendon with a straight distance of 2mm.There were rich anastomoses between the large cutaneous branch and the palmar digital artery at metacarpophalangeal joint. Conclusions Taken as an axis artery, the large cutaneous branch from the superficial radial artery can be used to supply an island flap for soft tissue defect in hand .
