摘要
冠状动脉夹层是指冠状动脉内膜撕裂，血液进入冠状动脉中膜或内膜下血肿形成，可导致管腔急剧变窄和血流严重受阻。若诊治不及时，冠状动脉夹层可能会引发受累冠状动脉的破裂、急性心肌梗死、心源性休克、猝死等严重临床后果。本文就冠状动脉夹层的分类及成因、影像学诊断、治疗策略作一综述。
Coronary artery dissection results from a tear in the inner layer of the artery, the tunica intima. This allows blood to penetrate and then to form an intramural hematoma in the central layer, the tunica media, and a restriction in the size of lumen. If the diagnosis and treatment is not prompt, the coronary artery may develop a tear, causing blood to flow between the 2 layers which forces them apart. And then the dissection may result in rupture of coronary artery, which in turn causes myocardial infarction, cardiogenic shock, and even sudden death. In this paper, we reviewed the genesis, imaging diagnosis and treatment strategies of this disorder.
