【摘要】 为探讨真皮下血管网皮瓣血供特点,选用家猪为实验动物,在臀部两侧分别形成以旋髂深血管分支主干为蒂的传统岛状皮瓣为对照侧和远侧50%修薄的真皮下血管网岛状皮瓣为实验侧,用皮温测定、激光多普勒、皮瓣荧光染色、透明标本等方法,进行自身对照研究。结果,实验侧皮瓣的血供显著降低,临床吻合血管的游离移植结果与此一致。其实质是轴型皮瓣和随意型皮瓣的联合体。临床14例15块皮瓣,修薄最大面积占皮瓣总面积60%,平均49%,均获满意效果。更多还原

【Abstract】 A comparison study on the blood supply of the buttock subdermal vascular network is- land skin flap and the conventional buttock island flap was undertaken in pigs.The former was created by thinning the distal half of the conventional buttock island flap,preserving the subdermal vascular network.Evaluation was made by measurement of skin temperature,laser Doppler,fluorescence stain, ink perfusion,microangiography and transparent specimen technique.It was found that the blood supply of the subdermal vascular network island skin flap was much lower than that of the conventional island flap.The reason was thought to be the change in the blood supply after the conventional island flap was thinned.The subdermal vascular network island skin flap was composed of the axial pattern and the ran- dom pattern.Fifteen subdermal vascular network island skin flaps have been successfully transferred with vessel anastomosis in 15 patients.The average area of the thinned distal part was 49% of the flap, with the maximum of 60%.更多还原
