Background Pseudoxanthoma Elasticum(PXE) is a rare,inherited,systemic disease of elastic tissue that in particular affects the skin,eyes,and cardiovascular system.

背景弹性纤维假黄瘤(pseudoxanthoma elasticum,PXE)是一种少见的常染色体遗传性疾病,主要累及弹性组织,可侵犯人体多个器官和系统,主要表现为皮肤、眼、心血管系统损害。

Under the gigatic impact of blood stream,the core stream impact the furcation of ACA-OA and lead the endoelastic membranecorrupt,endothecium cell damage,the collogen of vascular elastic tissue and smoothmuscular layer and the vascular wall is damaged ,these reasons cause the aneurysmformation.

在高血压的基础上，结扎一侧颈总动脉增加了对侧的脑灌注，在巨大的血流冲击下，轴心血流冲击ACA-OA分叉部导致局部血管壁内弹力膜破坏、内皮细胞受损、血管弹力组织和平滑肌层及动脉瘤壁中的胶原受损，致使动脉瘤形成。
