A comparison study on the blood supply of the buttock subdermal vascular network island 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 random 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%.
在猪身上进行了臀下皮下血管网岛状皮瓣与传统臀岛状皮瓣血供的比较研究。前者通过将传统臀岛状皮瓣的远端一半变薄而形成，保留皮下血管网。通过测量皮肤温度、激光多普勒、荧光染色、墨水灌注、微血管造影和透明标本技术进行评估。结果发现，皮下血管网岛状皮瓣的血供远低于传统岛状皮瓣。原因被认为是传统岛状皮瓣变薄后血供发生了变化。皮下血管网岛状皮瓣由轴型和随意型组成。15例患者的15个皮下血管网岛状皮瓣已成功通过血管吻合进行转移。变薄远端部分的平均面积为皮瓣的49%，最大为60%。
