Patient: Ask the expert: my father is 73 years old, recently found abdominal aortic aneurysm, 3CM, with high blood pressure, diabetes, what treatment method has been dizziness, heart tightness, heart pain, after a period of hospitalization hanging some relief (when coronary heart disease and heart disease treatment), two months ago found abdominal aortic aneurysm 1CM, now 3CM. such as surgery, when can be carried out? Ge Hongwei, Department of Vascular Surgery, Changzhou First People’s Hospital: The diameter of the abdominal aorta in adult men is 1.5-2.5CM, and a permanent limited arterial dilatation with a diameter of more than 1.5 times the normal value is called an aneurysm. Once the aneurysm ruptures, the death rate is even as high as 90%. More patients with abdominal aortic aneurysm have a combination of coronary atherosclerotic heart disease, emphysema and other medical diseases, which are poorly tolerated, and the 5-year survival rate is less than 20% if the abdominal aortic aneurysm is not treated. Aneurysm diameter that increases by 0.5CM or more during six months of dynamic observation should be considered as an indication for elective surgery. Please refer to the following indications for surgery, such as comprehensive literature: (1) aneurysm diameter R5CM, asymptomatic (2) aneurysm diameter 5CM, combined with aneurysm rupture high factors such as hypertension, aneurysm asymmetry, obstructive lung disease, etc. (3) pain or pressure regardless of aneurysm size (4) compression of urinary tract, (5) those who cause symptoms in the gastrointestinal tract (6) those who cause embolism in the distal arteries (7) those who have huge tumors and are in poor physical condition, which can be improved by medical treatment, may also be treated surgically. Contraindications to surgery: (1) Very poor general condition, serious diseases of heart, brain, lung, liver, kidney and other important organs and loss of function. (2) Patients with malignant tumors or other diseases with an expected survival of less than 2 years. Therefore, it is recommended that the above patients should go to a hospital that is equipped to cure abdominal aortic aneurysm disease for detailed examination and comprehensive evaluation, and then undergo surgery as soon as possible, or if they have cardiopulmonary insufficiency, they should first undergo medical treatment until their symptoms improve. Surgical treatment includes: (1) open surgery – abdominal aortic aneurysm resection and artificial vessel replacement (2) minimally invasive intervention – abdominal aortic intracavitary isolation. The specific surgical plan should be selected according to the patient’s pathological characteristics and economic status.
