Endothelia damage included the endothelium ecclasis,monocyte and platelets adherence to from thombus at the exposed subendothelia layer.

膜平滑肌向下迁移，引起膜肥厚，而膜则出现局部平滑肌缺如。

The endothelium pachynsis and local smooth muscle depletion was found because of the smooth muscle translation to subendothlial layer.

膜还发现胞坏死，尤其是靠近弹力板处坏死物向膜排入，加剧了膜损害。
