【摘要】 目的寻求一种更为安全、有效的足部组织游离移植再造拇、手指及关节功能的新方法,进一步提高手术成功率。方法对足部跖底与跖背动脉系统进行显微解剖学研究。设计并应用逆行游离、吻合跖底动脉的足部组织游离移植术治疗76例拇、手指及手部关节缺损患者,其中第二足趾移植58例,第二足趾复合组织移植4例,近侧趾间关节移植8例,(?)甲瓣移植6例。分析总结其疗效。结果第一跖底动脉解剖恒定,到第二足趾的分支粗于第一跖背动脉。75例患者全部成活,移植部位外观良好,功能明显改进,总成活率为98．7%。另1例行第二足趾游离移植再造拇指术患者因顽固性动脉痉挛而改用锁骨下皮管包埋。结论应用逆行游离跖底动脉为蒂的足部组织游离移植术可以克服其它方法存在的血管解剖变异较大、操作复杂、费时等不足,提高了手术效率和成功率。更多还原

【Abstract】 Objective To explore a new method of functional reconstruction of hand digits and joints with free transfer of foot tissues so as to increase the success rate of the operation.Methods After micro-anatomic study of the plantar and dorsal metatarsal arteries,retrograde and free grafts of foot tissues pedicled with plantar metatarsal arteries were designed and applied in transplantation to treat 76 cases of hand digital or joint defects.The surgeries included 58 cases of transfer of the second toe,four cases of transfer of composite tissues of the second toe, eight cases of transfer of proximal interphalangeal joint,and six cases of nail flap transfer.Results The mi- cro-anatomic study found that the first plantar metatarsal artery was anatomically constant and the diameter of its branch to the second toe was larger than that of the first dorsal metatarsal artery.Flaps survived in 75 of the 76 patients(98.7%),with fine appearance and significantly improved function.One patient who had received free transfer of the second toe to reconstruct the thumb function had to undergo a second repair with infraclavicula skin tube because of refractory arteriospasm of anastomosed vessels.Conclusion Transfer with free retrograde grafts of foot tissues pedicled with plantar metatarsal artery to reconstruct hand functions can effectively improve the success rate of the operation,because it is free of the shortcomings of great anatomic variation of blood vessels and time-consuming and complex procedures in conventional transfer.更多还原
