A better knowledge of the leg skin blood supply has recently revived interest in the cross-leg technique for skin grafts. It is now possible to delineate on each leg two flaps that contain arteries and veins. The internal saphenous flap, taken on the internal aspect of the leg is fed by the cutaneous branch of the greater anastomotic artery, satellite of the internal saphenous nerve, while the external saphenous flap, located on the postero-external aspect of the leg, is fed by 2 cutaneous branches of the popliteal artery or gemellar arteries. The length to width ratio of these flaps varies from 3 to 4, which is both safe and reliable and provides for supple handling of the pedicles and increased patient's comfort.
最近，对腿部皮肤血液供应的更深入了解重新唤起了人们对用于皮肤移植的交叉腿技术的兴趣。现在可以在每条腿上划定两个包含动脉和静脉的皮瓣。取自腿部内侧的隐静脉内侧皮瓣由大吻合动脉的皮支供血，大吻合动脉是隐神经的卫星动脉，而位于腿部后外侧的隐静脉外侧皮瓣则由腘动脉或双支动脉的2个皮支供血。这些皮瓣的长宽比在3到4之间，既安全可靠，又便于灵活处理蒂部，提高了患者的舒适度。
