摘　　要：目的探讨指侧方静脉动脉化在末节断指再植中的应用疗效。方法2007年3月至2012年4月，对20例末节断指患者，在正常指动脉多次吻合失败后行指侧方静脉动脉化，用近端优势侧指动脉与远端优势侧指侧方静脉吻合作为供血通路，吻合非优势侧指侧方静脉作为回路。结果所有患者的再植指均成活，创面均一期愈合。18例获6—12个月随访，再植指外形良好、指腹饱满、指体无明显萎缩；指甲生长近平整，长度平均为（15．6±2．7）mm；远侧指间关节活动度平均为（62±4）。，两点辨距觉平均为（4．6±0．3）mm，感觉测定平均S3^＋。结论指侧方静脉动脉化再植末节断指可提高再植指成活率，促进指甲生长及感觉恢复，增强远侧指间关节活动度，为正常供血多次失败后的末节断指提供了一种更有效的补救方法。Objective To investigate effect of veno-arteriolization of finger lateral vein for repairing severed finger tips. Methods From March 2007 to April 2012, 20 patients with severed finger tips were treated with veno-arteriolization of finger lateral vein after failure in anastomosing artery of finger over times. During operation, the dominant digital artery at proximal end and the dominant finger lateral vein at distal end was anastomosed as the blood supply, the non-superiorty finger lateral vein was anastomosed as the blood drainage. Results All flaps survived completely and achieved primary healing. 18 patients were successfully followed up for 6 to 12 months with satisfactory appearance and nail growth. Finger pulp was plump with good flexibility. The average length of nail was （ 15.6 ± 2.7 ） mm and the average motion of DIP joint was （62 ± 4） °. The average two point discrimination was （4. 6 ± 0.3 ） mm and the average sensation measurement was S3^＋. Conclusion The veno-arteriolization of finger lateral vein is a valuable method for repairing severed finger tips, which can promote nail growth, and restore fingers motion and sensation.
