Once diagnosed with aortic aneurysm, especially those with thoracic aortic aneurysm diameter greater than 5 cm and those with abdominal aortic aneurysm diameter greater than 6 cm, timely surgery should be performed to avoid accidents. If there are important organs under pressure and respiratory distress and severe pain occur with a tendency to rupture, early surgery should be performed. For acute entrapped aneurysm, if there is no important organ compression or serious complications, non-surgical medical treatment should be considered first, and surgery should be performed after the condition is stabilized, because the acute entrapped vessel wall tissue is edematous and brittle, and it is easy to tear off and bleed after suture, so the risk of surgery is high. 1, non-surgical treatment Should be closely observed, using antihypertensive drugs to control blood pressure in the appropriate range, using sedative drugs and drugs to reduce the contractility of the heart, so that the patient rest quietly to avoid further development of the disease. For patients with cardiac insufficiency, cardiotonic drugs can be used. If the condition progresses, surgery should be performed in time. 2.Surgical treatment Depending on the presence or absence of aortic valve lesion and the length and location of the aneurysm, the aneurysm can be removed and the artificial blood vessel can be replaced at the same time, such as aortic valve damage, aortic valve replacement surgery and coronary artery transplantation (Bentall’s operation), aortic arch replacement, and the proximal end of the aneurysm wall with the artificial blood vessel is anastomosed and the artificial blood vessel is sent to the distal end of the aorta. The procedure is performed by anastomosing the proximal end of the aneurysm wall with an artificial vessel and feeding the artificial vessel into the distal aorta.
