Type A aortic coarctation involves the ascending aorta, while type B originates from the thoracic descending aorta and does not involve the ascending aorta. The clinical manifestations of the two types differ according to the location of the lesion, and the treatment modalities are also different. 1. Aortic coarctation type A, half of the patients may have aortic valve closure and heart failure, but also can see myocardial infarction, cardiac tamponade, which is unique to the performance of Aortic coarctation type A. In principle, it should be treated by emergency surgery. In principle, it should be treated by emergency surgery, open chest, with extracorporeal circulation to support the replacement of the clamped segment of blood vessels. type A aortic coarctation is a critical condition, with a poorer prognosis. 2. Aortic coarctation type B, manifested as acute lower limb ischemia, the examination of the pulse weakened and disappeared, limb cold, etc., should be in the medication to control the blood pressure, heart rate stabilization, a limited period of time to perform vascular endoluminal repair, such as medication is difficult to control, the emergence of aortic rupture signs or lower limb ischemia manifestation of the obvious, should be the emergency endoluminal repair of blood vessels, the operation than the A-type aortic open thoracotomy surgery is less traumatic, fewer complications, prognosis better than the A-type. Once aortic coarctation is diagnosed, it is recommended to go to the hospital in time to avoid accidents.
