title: Fingertip Replantation Using Y-Shaped Vein Graft to Pulp Artery.
abstract: Re-establishing adequate venous outflow is the most important factor for success of fingertip replantation. However, in zone I level, replantation is very difficult, especially in repairing venous circulation. The authors have made an attempt to replantation using Y-shaped vein (YSV) graft to identify and repair veins easily in fingertip replantation. From January 2007 to December 2012, a total of 46 fingertip replantations in 44 consecutive patients with amputations in the Tamai zone I level were performed by using YSV graft. In all patients, arterial anastomosis was performed using YSV graft, and interpositional vein grafts were used for venous repair. The overall success rate of the YSV-grafted replantations was 91.3% (42/46). Postoperative vascular complications occurred in 6 YSV-grafted replantations (13%), and pulp atrophy in the YSV-grafted digits was 9.5% (4/42). Fingertip replantation in zone I level is a difficult territory to a microsurgeon, especially anastomosing veins. However, our YSV grafting technique has shown value in this setting, enabling better esthetic and functional results.
