It is accepted that the ulnar artery forearm flap is dependent on the integrity of the palmar arches for ulnar arterial backflow and the patency of both radial and ulnar arteries. A patient is presented who demonstrates the successful use of the ulnar artery forearm flap supplied by the dorsal carpal arch via the dorsal branch of the ulnar artery. In this patient, the ulnar artery was damaged distal to the dorsal branch of the ulnar artery. A distally based ulnar forearm was dissected up to the dorsal branch of the ulnar artery and pivoted around this branch. This flap survived completely with no postoperative problem.
一般认为，尺动脉前臂皮瓣依赖掌弓的完整性以实现尺动脉的逆向血流，以及桡动脉和尺动脉的通畅。本文报道了一名患者，成功使用了通过尺动脉背侧支由腕背弓供血的尺动脉前臂皮瓣。在该患者中，尺动脉在尺动脉背侧支的远端受损。将一个以远端为蒂的尺侧前臂皮瓣解剖至尺动脉背侧支，并围绕该分支旋转。该皮瓣完全存活，术后无问题。
