What are the complications of aortic dissection?

During the treatment of aortic dissection, patients must adopt correct treatment and nursing methods, otherwise it is easy to cause complications of aortic dissection. Aortic dissection itself is a relatively serious disease. If complications arise, it may lead to body collapse and cardiac tamponade and death. Therefore, patients suffering from aortic dissection need to be aware of the complications of aortic dissection.

1. Ascending aortic dissection: Ascending aortic dissection is common during and after surgery. The most serious consequence is rupture of the ascending aorta, cardiac tamponade and death. If discovered in time, the patient can survive. Ascending aortic dissection is undoubtedly the most serious complication.

2 The primary rupture is not completely closed: In some patients with postoperative endoleak, the false lumen can remain open for a long time, and a thrombus can be partially formed inside it. The diameter of the descending aorta may be affected and may or may not increase. In some patients with postoperative endoleak, the endoleak may disappear, and a thrombus may be completely formed in the false lumen. Stent endoleak is a common complication. The larger the intimal rupture and the closer it is to the left subclavian artery opening, the easier it is to produce endoleak. Even if the left subclavian artery opening is completely closed, endoleak cannot be completely avoided.

4 Cerebrovascular accident: Some patients may suffer from cerebral infarction during surgery, leading to hemiplegia. Patients with serious complications may suffer from cerebral hemorrhage and death. It often occurs in patients with high blood pressure after surgery. The cause of intraoperative cerebral infarction is unknown, which may be related to the detachment of arteriosclerotic plaques and controlled hypotension during surgery. Postoperative cerebral hemorrhage is related to hypertension. Patients with aortic dissection often have hypertension and arteriosclerosis.

5 Peripheral vascular injury 2 Aortic regurgitation Sudden aortic regurgitation is a common complication of type A AD. It is currently believed that the cause of the disease may be dissection causing enlargement of the valve ring or involvement of the valve leaflets or torn intimal membrane protruding into the left ventricular outflow tract, which is easily misdiagnosed as other causes of aortic regurgitation and pericardial tamponade. The effusion can be caused by inflammatory exudative reaction around the diseased aorta, or it can be caused by transient rupture or leakage of AD, resulting in pericardial hemorrhage, which is easily misdiagnosed as pericarditis.
