We previously reported pedicled venous flap survival using the rat model, as well as venovenous, arteriovenous, and arterialized flow-through venous flap survival using the rabbit ear model. For this study, we utilized these flaps clinically. Five of seven pedicled venous flaps survived, displaying superficial necrosis. The others became partially necrotic; they were transferred after dissection of a long pedicle vein. Eight of nine venovenous flow-through venous flaps survived; six displayed superficial necrosis. The nonsurviving flap became completely necrotic, possibly because only one donor vein and one recipient vein were used. Six of 10 arteriovenous flow-through venous flaps survived. The remaining four became partially necrotic, possibly because only one vein was anastomosed for outflow. The arterialized flow-through venous flap survived. The pedicled venous and venovenous groups studied seem likely to survive despite superficial necrosis. However, the draining vein should not be dissected more than 5 cm, and many draining veins should be anastomosed with recipient vessels.
我们之前报道了使用大鼠模型的带蒂静脉皮瓣存活情况，以及使用兔耳模型的静脉 - 静脉、动脉 - 静脉和动脉化通血静脉皮瓣的存活情况。在本研究中，我们将这些皮瓣应用于临床。7个带蒂静脉皮瓣中有5个存活，表现为表面坏死。其他皮瓣出现部分坏死；它们是在解剖一条长的蒂静脉后进行转移的。9个静脉 - 静脉通血静脉皮瓣中有8个存活；6个表现为表面坏死。未存活的皮瓣完全坏死，可能是因为仅使用了一条供体静脉和一条受体静脉。10个动脉 - 静脉通血静脉皮瓣中有6个存活。其余4个出现部分坏死，可能是因为仅吻合了一条静脉用于引流。动脉化通血静脉皮瓣存活。所研究的带蒂静脉组和静脉 - 静脉组尽管出现表面坏死但似乎有可能存活。然而，引流静脉的解剖长度不应超过5厘米，并且应将多条引流静脉与受体血管吻合。
