目的　探讨指动脉静脉化重建手指再植血液回流的方法和疗效。  方法　应用离断手指远断端非优势侧指动脉与近断端指掌侧静脉或指侧方静脉吻合治疗手指末节离断病人18例，其中指动脉与指掌侧静脉吻合11例，与指侧方静脉吻合7例。  结果　成活16例，坏死1例，部分坏死1例。  结论　指动脉静脉化为断指再植提供了重建静脉回流的一种有效方法。

Objective　To explore effects of anastomosis of arteries and veins on blood backflow after finger replantation.　Methods　Distal end of the nondominat side finger artery of amputated finger were anastomosed with the proximal end of the palmar digital veins or finger lateral vein for treating 18patients with distal segment severed fingers. In which, 11 cases received anastomosis of finger artery and palmar digital vein, 7 cases received anastomosis of finger artery and finger lateral vein.　Results　Replanted fingers survived well for 16 patients, however, finger necrosis appeared in 1 case, and partial necrosis in 1 case.　Conclusions　Arterio-venous anastomosis is effective method for treating amputated fingers.
