暂时性异位断足寄养再回植术

TEMPORARY ECTOPIC IMPLANTATION OF AMPUTATED FOOT

目的 报道 2例采用暂时性异位寄养再植技术 ,挽救无一期再植条件的断足及在特殊条件下的断足再植方法。方法 对无一期再植条件的 2例断足 ,采用暂时异位寄养的方法 ,分别再植于健侧小腿下段 ,分别利用胫后动脉和大隐静脉作为受区血管 ,维持断足存活。待全身状态平稳和离断肢体近端条件允许时 ,再将断足自寄养部位二期回植于原来的解剖位置。结果 2例断足完体成活。经 4～ 6个月随访 ,受伤的下肢恢复正常长度 ,足底感觉恢复。能下地行走。结论 暂时性异位寄养再植技术为挽救特殊条件下的离断肢体提供了一种新的选择 ;

Objective To investigate an effective technique of temporary ectopic implantation for amputated extremity under complex condition. Methods Two cases of amputated foot, which could not be implanted primarily, were treated with temporary ectopic implantation. The other leg of patient was chosen as recipient site. The posterotibial artery and saphenous vein were chosen as recipient vessels. When the general condition and the proximal condition of the amputated part were suitable, the ectopic implanted feet were transferred to their anatomic positions. Results All the feet survived after the replantation. The injured limbs recovered their normal length and sensation. The patients could walk after 4 6 months. Conclusion Temporary ectopic implantation is an ideal technique for the salvage of amputated limb and organ under special condition. Severed foot and lower segment of the leg under complex condition were the best indication for the temporary ectopic implantation.
