Mangled finger with impaired arteria digitalis communis remains to be a challenge for replantation surgery due to the limited amount of tissue to work with. Out of 554 hands with total finger amputations treated by replantation of finger/fingers from July 2012 to June 2018, there were 7 cases of damaged arteria digitalis communis, all of which were replanted by anastomosing distal adjacent radial/ulnar digital artery to distal end of ulnar/radial digital artery of amputation finger, and 2 veins were anastomosed for each finger. A skin pedicle was made by suturing both dorsal and palmar skin of adjacent fingers, and detachment was performed 4 weeks postoperatively. The survival rate was 100%. Mean total active motion was 191.4° (ranging from 170 to 220°). Mean 2-point discrimination was 8 mm static (ranging from 6 to 11 mm), and mean grip strength was 35.3 kg (range, 29 to 40 kg). Based on our experience, cross-finger revascularization is an effective and safe alternative for mangled finger salvage when arteria digitalis communis is damaged, and good functional prognosis can be expected.

使用交叉手指血管重建术挽救手指

由于要处理的组织数量有限，手指交叉指肠受损的碎片缠结仍然是移植手术的挑战。2012年7月至2018年6月，在554只手的全部手指截肢术中，通过手指/手指的再植术进行了治疗，其中7例受损的洋地动脉共用，所有这些均通过将远端adjacent骨/尺骨指动脉远端吻合到远端截肢手指的尺/ radi指动脉，每个手指吻合2条静脉。通过缝合相邻手指的背侧和掌侧皮肤制成蒂，并在术后4周进行分离。存活率为100％。平均总主动运动为191.4°（170至220°）。平均2点分辨力为8毫米静态（6到11毫米），平均握力为35.3千克（29至40千克）。根据我们的经验，手指交叉血运重建术是一种有效且安全的替代方法，可在手指总动脉受损时挽救手指受损，并且可以预见良好的功能预后。
