Conclusion the hypertensive and hyperoximic arterial blood could damage the venous endothelial cells after the vein was arterialized if the flap was transplanted after the damaged endothelial cells recovered , the survival rate and the quality of the flap could be increased remarkably 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。
