The inferior epigastric venous flap of the rat was chosen for experimental studies of vascular flow alterations. The long saphenous vein was not selected for use; preliminary studies involving forced retrograde injection demonstrated that it drains blood primarily from the leg and foot, not from its overlying skin. Eight different flap designs were studies: group A, saphenous flap, simple isolation with pedicle; group B, inferior epigastric flap, simple isolation with pedicle; group C, inferior epigastric flap, simple isolation with interpositioned Silastic sheet; group D, cross-transferred venous pressure arterial flap; group E, cross-transferred, arterialised venous flap; group F, arterialized venous flap, in which arterial blood was shunted away via the main vein: group G, cross-transferred venous pressure venous flap; and group K. control, nonvascularized flap. Three more groups (H, I, J) were introduced by repeating the flap designs of groups E, F, and G but preceded by forced perfusion of the venous system using 5 cc of normal saline at 200 mm Hg. The best results were obtained with groups B, C, E, H, and I. The other flaps necrosed. The results are discussed based on the assumption that true retrograde venous blood flow does occur.
选用大鼠腹壁下静脉皮瓣进行血管血流改变的实验研究。未选用大隐静脉；初步的强制逆行注射研究表明，它主要引流腿部和足部的血液，而非其上方皮肤的血液。研究了八种不同的皮瓣设计：A组，隐静脉皮瓣，带蒂单纯分离；B组，腹壁下皮瓣，带蒂单纯分离；C组，腹壁下皮瓣，带蒂单纯分离并插入硅橡胶片；D组，交叉转移静脉压动脉皮瓣；E组，交叉转移动脉化静脉皮瓣；F组，动脉化静脉皮瓣，其中动脉血经主静脉分流；G组，交叉转移静脉压静脉皮瓣；K组为对照，非血管化皮瓣。通过重复E、F和G组的皮瓣设计，但在使用5毫升生理盐水以200毫米汞柱压力对静脉系统进行强制灌注后，又引入了另外三组（H、I、J）。B、C、E、H和I组取得了最佳结果。其他皮瓣发生坏死。基于确实发生了真正的逆行静脉血流这一假设对结果进行了讨论。
