摘要
目的：动态观察真皮下血管网皮瓣血供重建过程以确定提早断蒂的时机。方法：以猪为实验模型，采用ｒ照相机观察皮瓣核素分布及测定皮瓣内核素清除率等技术，动态观察皮瓣血供重建与对蒂部的供血范围。结果：随意型真皮下血管网皮瓣的血供来自三个方面，即蒂部供血，创面基底与创缘周边，单纯蒂部供血不足以使皮瓣远端超比例部分成活。结论：真皮下血管网皮瓣术后７天基本完成血供重建，７天断蒂是可行的。临床应用１２例，效果满意。
The skin flaps on the back of piglets were taken as experimental pattern. The isotope distribution and clearance in the skin flap were determioned by r-camera. This study demonstrated that the blood supply of subdermal vascular network skin flap came from its pedical, wounds and edges. The distal portion of super-rate flap with subdermal vascular network failed to survive if only by its pedical blood supply. The blood supply reconstruction was finished on 7th days postoperation.
