预构皮瓣的研究进展

目的 总结预构皮瓣的实验研究进展及临床应用成果。方法 广泛查阅有关预构皮瓣的实验研究及临床应用的文献报道综述及研究成果，提出尚需解决的问题。结果 实验研究已证明，预构皮瓣的血管化过程主要是植入血管与皮瓣原血管间的直接沟通，其次是植入血管新生形成完整的血管网并支配整个皮瓣，３～４周血管成熟，可进行皮瓣转移。临床应用方面将颞浅动静脉、胃网膜血管、旋股外侧血管及胸背血管等预构皮瓣带蒡移位或游离移植，均攻

DEVELOPMENT OF PREFABRICATED FLAPS

Objective\ To sum up the experimental development and clinical application of prefabricated flap. Methods\ The reported experimental results and clinical application of prefabricated flap extensively reviewed.Results\ Previous studies had proved that the revascularization of prefabricated flap mainly through anastomoses of implanted vessels and the original vessels of the flap, the implanted vessles slowly formed a new and complete blood vessel network, which could dominate the whole flap, three to four weeks later, the new vessels were mature and the flap could be transferred. Clinically, the superficial temporal vessels, gastroepiploic vessels, circumflex femoral vessles and thoracodorsalis vessels could be harvested for prefabricated flap with satisfactory results. Conclusion\ Prefabricated flap provides a new method for the treatment of complicate defects.
