腓肠外侧皮动脉蒂顺逆行岛状皮瓣─—适应证选择及其并发症防治

The Indications and the Methods of Drevention of itsComplications During the Use of Skin Hap Transplanta-tion Dedicled by the Lateral Gastrocneumic CutaneousArtery

本文通过５０侧正常国人新鲜下肢的解剖学观察，探讨皮瓣的血液循环模式及手术适应证，通过２５例临床实践进一步探讨手术适应证的选择，并总结并发症及其防治要点。

AbstractThe authors dissected 5 0 normal fresh specimens ofthe lower extremities in order to investigate the circulationmodel and the operation selections for the clinical applica-tion of skin fla p transplantation.25 cases were presen tedillustrating the operati ve selection of the skin flap modelbased upon the findings of the anatomical dissection.Thelateral cutaneous gastrocneumic artery originated from thepopliteal artery,and existed in 100% of the dissectedspecimens.Using this artery,a vascular pedicle of 9-11cmcan be obtained.Vascular pedicled island skin flaps,7 re-versed, and 18 ipsidirectional,were transplanted in 21male and 4 female patients with the age range of 5-54years.Complete primary healing of the skin flaps were ob-tained in 22 cases. The common complications are necrosisof the skin flap,hematoma formation under the flap,infection and wound rupture.The most important point toprevent the complications is to design the flap within theskin area supplied by the lateral cutaneous gastrocnemeus artery.
