采用大鼠腹股沟皮瓣模型，探讨动静脉瘘（AVF）对皮瓣生存能力的影响。这些动物被随机分为三组。组1为岛状皮瓣，组2和组3为半岛状皮瓣，包括腹壁浅动脉和静脉均升高。在第二组中，半岛基部位于皮瓣的直侧；在第3组中，半岛的底部位于其下端。皮瓣抬高后，动静脉切开术，在股总血管水平近蒂侧对侧吻合造A-V瘘。然后将皮瓣缝合回他们的床上。所有带AVF的岛状腹股沟襟翼都失效了。第3组皮瓣血流严重减少，无皮瓣存活；然而，第二组的皮瓣全部存活，没有任何问题。结论：皮瓣蒂近端AVF对岛状皮瓣循环有不利影响。如果皮瓣和AVF的处理与第2组相同，则该模型可以克服血流减少引起的皮瓣坏死。
An experimental study was done in a rat groin flap model to assess the possible effects of arteriovenous fistulas (AVF) on the viability of skin flaps. The animals were randomly divided into three groups. In Group 1, an island flap, and in Groups 2 and 3, peninsular flaps, including the superficial epigastric artery and vein, were elevated. In Group 2, the base of the peninsula was on the rectus side of the flap; in Group 3, the base of the peninsula was located on the lower extremity side. After elevation of the flap and following arteriovenotomy, an A-V fistula was produced by side-to-side anastomosis proximal to the pedicle at the level of the common femoral vessels. Then the flaps were sutured back into their beds. All the island groin flaps with the AVF failed to survive. In Group 3, there was a severe reduction of blood flow in the flap and no flaps survived; however, all the flaps in Group 2 survived totally with no problem. It was concluded that island skin flap circulation is negatively affected by an AVF proximal to the flap pedicle. If the flap and AVF are treated as in Group 2, then flap necrosis caused by reduced blood flow can be overcome in this model.
