手指复合组织块离断再植的临床研究

目的探讨不同手术方式对手指离断复合组织块再植的临床疗效。方法对48例离断复合组织块采用缝合动脉主干或分支、静脉或静脉动脉化进行原位再植。结果48例手指离断复合组织块除1例因发生静脉危象坏死，余全部成括。随访6个月～3年时间，再植复合组织块颜色红润，感觉恢复S3～S4级，指体外观功能良好，患者满意。结论手指离断复合组织块应积极再植，通过缝合指固有动脉或其分支，缝合静脉或静脉动脉化，增加再植成活率。

Clinical Research of Replantation of Severed Finger Composite Tissue

Objective To explore the methods of replantation for severed finger composite tissues. Methods All severed composite tissues of 48 cases were replanted in situ through artery and vein anastomosis or vena arterialization. Results Except one severed composite tissue was failed for vena crisis,the rest 47 cases were survived. By 6 months- 3 years follow-up,the finger appearance were satisfactory with sense recovery by level S3-S4. Conclusion Severed finger composite tissues should be replanted positively through anastomosing inherent digital arteries,veins or their branches or vena arterialization to improve the survival ratio.
