单一修复动脉的指尖断指再植13例

目的 探讨指尖完全离断无修复静脉条件时,只用单一修复动脉的方法再植的成活率.方法 指尖(掌侧螺纹中心以远)完全离断再植时,在无行静脉回流重建条件的情况下,只单一修复动脉13例,术后常规使用低分子量肝素抗凝,部分病例行再植指侧方切开放血或甲床放血,观察再植指成活情况.结果 成活12指,1例失败.术后随访3～12个月,再植指外形饱满,两点辨别觉为2～7 mm,运动功能正常.结论 指尖因组织量小,自身静脉回流建立较快,只用单一修复动脉的方法再植也可成活.根据病情,采用再植指侧方切开放血或甲床放血,可提高指尖再植的成活.

Replantation of complete severed fingertip with only artery anastomosis: 13 cases report

Objective To investigate the replantation of complete severed fingertip when vein can't be repaired and only artery be repaired. Methods All 13 cases complete severed fingertips were replantated with only artery anastomosis but vein cannot be repaired.Low molecular weight heparin was applied to prevent blood clotting postoperation. Blood-letting by nail extraction or latero-incision were done in some cases.The survival fingers were observed. Results After 3-12 months followed-up,12 cases survived with satisfactory appearance and locomotion,2-PD of 2-7 mm,but 1 case was failed. Conclusion The replanted fingertip may survival with only artery anastomosis because of fewer tissue and faster recontruction of venous return.It would raise the survival rate of replanted fingertip by blood-letting by nail extraction or latero-incision according to the traumatic condition.
