主动脉也能破开？

主动脉破裂（aortic rupture）是指主动脉的所有血管壁层完全破裂。主动脉是人体最大的动脉，主动脉破裂属罕见但极度危险的疾病，被视为医疗紧急情况。

主动脉破裂可依病因分类为以下主要类型：

• 创伤性主动脉破裂
• 因主动脉瘤破裂而产生的的主动脉破裂

主动脉破裂死亡率高达 90% 。

媒体报道关于 Lindsey Graham 有两个说法：aortic rupture (主动脉破裂)、aortic tear (主动脉(内膜)撕裂)。

主动脉(内膜)撕裂也称 aortic dissection (主动脉剥离)，它是是主动脉内膜撕裂，这可能会阻断血液经主动脉流向心脏或腹部器官；它的致命性相对较弱，但也很凶险 (https://en.wikipedia.org/wiki/Aortic_dissection)。
