目的提高静脉动脉化皮瓣的存活率。方法根据静脉内皮细胞需要一定时间以适应动脉血流，以及皮肤扩张器可增加血管密度等特点，首先将皮瓣静脉原位动脉化，同时加用皮肤扩张器预制，１０周左右行Ⅱ期皮瓣移转。结果静脉动脉化皮瓣的存活率显著提高，从３９．１３％提高到８６．３６％，挛缩率从３２．０８％下降到８．９％，两者均有统计学意义。结论静脉动脉化后高压、高氧动脉血流可损伤静脉内皮细胞，如先将静脉原位动脉化，待损伤的静脉内皮细胞修复并适应动脉血流后再行皮瓣移转，可明显提高皮瓣成活率及成活质量。
Objective To improve the survival rate of venous artery flaps. Methods According to the fact that vein endothelial cells need time to adapt to arterial blood flow and skin dilator can increase the density of blood vessels, the venous flap of the skin flap is artificially inflated in situ and prefabricated with skin dilator at the same time. Flap transfer. Results The survival rate of venous artery flaps increased significantly from 39.13% to 86.36%, and the contracture rate decreased from 32.08% to 8.9%, both of which were statistically significant. Conclusions After venous arterialization, high pressure and high oxygen arterial blood flow can damage the venous endothelial cells. If venous arterialization is performed first, venous endothelial cells can be repaired and adapted to arterial blood flow before they are transplanted, which can be obviously improved Flap survival rate and quality of life.
