The aim of this work was to compare the survival of an arteriovenous island flap with the survival of an island flap with a flow-through venous supply. Our experimental studies were performed on 95 Wistar rats randomised into six groups: Group 1: Indian ink injection of flow-through venous flaps with capillary network; Group 2: control group deprived of vascularisation; Group 3: control group with arteriovenous supply; Group 4: flow-through venous flaps of group 1; Group 5: epigastric flow-through venous flaps with a main venous trunk; Group 6: histological examination of flow-through venous flaps. The survival of flaps was monitored by direct examination, histological examination, capillaroscopy, and laser Doppler. Three out of 50 flow-through venous flaps survived. There was a statistically significant difference in the delay of clinical necrosis between the composite non vascularised free grafts (2.8 +/- 1.2 days) and the flow-through venous flaps (4.1 +/- 1.3 to 4.9 +/- 1.1 days depending on the type of flap). A 20% decreased venous blood flow was observed in the flow-through venous flaps.
这项工作的目的是比较动静脉岛状皮瓣的存活率与带通流静脉供血的岛状皮瓣的存活率。我们的实验研究在95只Wistar大鼠上进行，随机分为六组：第1组：对具有毛细血管网的通流静脉皮瓣注射印度墨水；第2组：无血管化的对照组；第3组：动静脉供血的对照组；第4组：第1组的通流静脉皮瓣；第5组：具有主要静脉干的上腹通流静脉皮瓣；第6组：通流静脉皮瓣的组织学检查。通过直接检查、组织学检查、毛细血管镜检查和激光多普勒监测皮瓣的存活情况。50个通流静脉皮瓣中有3个存活。复合无血管化游离移植物（2.8±1.2天）与通流静脉皮瓣（根据皮瓣类型为4.1±1.3至4.9±1.1天）之间临床坏死延迟存在统计学显著差异。在通流静脉皮瓣中观察到静脉血流量减少20%。
