At present, we have carried out the artificial blood vessel replacement with resection of ascending aortic aneurysm, aortic valve and ascending aortic replacement and coronary artery grafting (Bentall procedure), Bentall plus total arch replacement and intraoperative descending aortic endoluminal stenting, interventional treatment of thoracic aortic coarctation and aortic aneurysm, and aortic valve-preserving ascending aortic replacement and coronary artery grafting (David procedure). Various types of thoracic aortic aneurysm and the treatment of coarctation techniques. Aortic coarctation and its treatment: Aortic coarctation is the rupture of the inner membrane of the aorta, the high speed blood flow through the rupture will separate the inner membrane of the artery from the middle membrane, and the blood will flow from it, which will lead to coarctation of the ascending aorta and descending aorta. The rupture occurs at the beginning of the ascending and descending aorta. Patients with acute aortic coarctation often present with sudden, severe, severe pain behind the sternum or in the back of the chest, accompanied by shock. The condition of acute aortic coarctation is very dangerous, due to the rupture of the clamped blood vessel, or ischemia of the heart, brain, kidney and other vital organs caused by the clamping, within 48 hours of the onset of the disease, about 50% of the patients die, so early diagnosis is needed and timely treatment. Once aortic coarctation is clearly diagnosed, it should be treated immediately with surgery or intervention. Patients whose coarctation involves the ascending aorta need immediate surgical treatment. And only the distal part of the descending aorta is involved in the entrapment, it can be interventional therapy (the procedure is less traumatic, faster recovery), or surgical treatment. Thoracic aortic aneurysm and its treatment: Thoracic aortic aneurysm is called thoracic aortic aneurysm when the diameter of thoracic aorta reaches more than 50mm due to expansion of thoracic aorta for some reasons. The main causes are hereditary factors, such as Marfan syndrome, atherosclerosis, aortic coarctation, infection and so on. Symptoms of thoracic aortic aneurysm are mainly caused by compression of the enlarged tumor, such as anterior chest pain, hoarseness, and dyspnea, etc., but a significant number of patients have no symptoms, which are only detected when they undergo a thoracic CT or magnetic resonance imaging (MRI) examination. The main risk of thoracic aortic aneurysm is rupture, so once the diagnosis is confirmed, surgery is required. Surgery involves removing the diseased thoracic aorta and replacing it with an artificial blood vessel to restore the normal function of the blood vessel. Surgery for thoracic aortic aneurysm is highly effective.
