摘要
真皮下血管网皮瓣临床报道较多，但其血供规律研究较少。本实验选用８只体重２５～３０ｋｇ的家猪为实验动物，在臀部两侧分别形成以旋髂深血管分支主干为蒂的岛状皮瓣和远侧５０％修薄的真皮下血管网岛状皮瓣。用皮温测定、激光多普勒、皮瓣荧光染色、组织学检查、墨汁灌注及透明标本等方法，对两种皮瓣的血供特点进行了自身对照研究。结果表明：与传统皮瓣相比，真皮下血管网岛状皮瓣的血供显著降低，其实质是轴型皮瓣和随意型皮瓣的联合体。
In this study, 8 pigs, weight ranged from 25 to 30kg, were used. Island skin flaps with the deep circumflex iliac artery were designed as pedicle on both buttocks. In the distal half of the island skin flap, which had been made on the right buttock, a subdermal vascular network island skin flap was made by preserving the subdermal vascular network. Blood supply between the two types of skin flap was compared by skin temperature, laser Doppler, fluorescent stain, histological examination, ink perfusion microangiography and transparent specimen technique. The observation showed that the blood supply of the subdermal vascular network island skin flap was decreased prominently in comparison with that of the conventional island skin flap. The subdermal vascular network skin flap was actually a combination of axial pattern skin flap with randomized skin flap.
