什么是主动脉夹层 李菁 中日友好医院 主动脉夹层指主动脉没有发育好或其他原因，造成主动脉内皮组织跟平滑肌之间的组织，如弹性层比较疏松，比较差，会有囊性的扩张，如果血液打到主动脉，不停的冲击，可能会导致主动脉撕裂，血就打到主动脉两层中间去，让主动脉里的管腔变窄，血在里面形成血肿，把主动脉整个可能都压闭了，然后造成重要的脏器缺血，所有的组织细胞都得不到灌注。 What is aortic dissection Aortic dissection refers to the failure of the aorta to develop well or for other reasons, It causes the tissue between the endothelium and the smooth muscle of the aorta, If the elastic layer is loose, Poor, There will be cystic expansion, If the blood hits the aorta, Constant impact, May cause aortic tears, The blood goes between the two layers of the aorta, Narrow the lumen in the aorta, Blood forms a hematoma in it, The whole aorta may be closed, And then it causes ischemia of important organs, All tissue cells were not perfused.
