潘宝华,1963年生,1987年第四军医大学医疗系毕业,现任第四军医大学西京医院整形外科中心主治医师,医学博士,发表论文7篇,参编整形美容专著3部。[摘 要] 目的:研究在牵拉性撕脱损伤时动脉内膜的变化及其闭塞率。 方法:建立大白鼠动脉牵拉性撕脱伤模型,给予60～140g牵拉力,观察其内膜形态变化。 结果:随牵拉力的增加,闭塞率逐渐增大,至140g时达到100%。形态观察可分为:①内膜断裂型;②内膜瓣状型二个类型。牵拉损伤的动脉切断后原位显微吻合的成功率为83.33%。 结论:损伤动脉有特征性的内膜变化,瓣状型内膜损伤可导致血栓形成,影响显微外科的成功率。

[Abstract] Objective:To investigate the morphological changes and occlusion rate of post-avulsion injury artery. Methods:Rat model for arterial avulsion injury was developed.Distraction force of 60-140g was applied separately.The morphological changes of arterial endometrium were observed. Result:With the increasing of distraction forec,the occlusion rate was increased accordingly.When the distraction force increased up to 140g,the occlusion rate was 100%.The morphological changes could be divided into 2 main types:1.Endometrium rupture and 2.Endometrium valve formation.The injured artery was divided and anastomosed in situ,the patency rate was 83.33%. Conclusion:〖WT5"BZ〗There were typical endometrium changes after artery injury.Endometium valve formation leaded to thrombosis and further compromised the success of microsurgery. ......
