The human artery has a thicker wall compared to the vein, and is divided into three main layers, including the intima, mesima and epima. Arterial entrapment is caused by a localized tear of the intima, which is subjected to a strong blood flow, and the blood gradually peels off and expands, forming two lumens in the artery, resulting in a series of symptoms such as chest and back pain. Since this disease has no specific clinical symptoms, it is often confused with coronary heart disease and chest disease, which often leads to misdiagnosis. If there is sudden chest pain with malignant hypertension, except for coronary artery disease and common chest pain disorders, aortic coarctation should be highly suspected, and tests related to coarctation should be improved for differential diagnosis.
