Patient: Description (onset, main symptoms, hospital visited, etc.): The patient is male, 77 years old, a patient of farm 857 in Mishan, Heilongjiang province, suffering from coronary heart disease, cardiomegaly, heart failure. on October 25, the examination revealed 1. abdominal aortic aneurysm, 2. aneurysm of the upper anterior segment of the right renal artery, 3. multiple plaque formation in the abdominal aorta and branches Doctor: the systemic condition of the elderly is complicated, but whether surgery should be performed If the aneurysm is more than 5 cm in diameter, it should be treated actively, and endoluminal isolation is preferred. Patient: CT diagnostic imaging report: the entire abdominal aorta and its branches have an uneven inner wall, and low-density and high-density plaque shadows can be seen on the inner side of the vessel wall, with some branches having uneven thickness. The lumen of the lower part of the abdominal aorta to the bifurcation is obviously dilated, the range is about 6cm, the diameter of the thicker layer is about 4.5*4.0cm, the annular low-density shadow is visible in the vessel wall, and a round-like high-density shadow is visible in the upper anterior part of the right renal artery, the size is about 0.8*1.2cm This is the enhanced CT we did in Mishan Pei De Central Hospital In addition, I would like to ask: how dangerous is it for my father to have this operation? The patient: my father’s blood pressure is 110, 120, 130. low pressure 70, 80, 90. doctor: there are two main methods of surgery: 1. open surgery, which has existed for decades and is relatively mature, replaces the diseased blood vessels with artificial ones. the surgery is more thorough, and there are usually no problems such as endoleaks once you recover. However, the procedure must be done under general anesthesia, and only in experienced hospitals does it have a high success rate. For example, the mortality rate at my teacher – Wu Qinghua and Director Chen Zhong of Anzhen Hospital is only about 1%, which is close to the mortality rate of appendicitis, making a very large, very dangerous surgery very safe; generally experienced doctors do this surgery in about 2-3 hours, I usually do it in our hospital is about 2 hours, our hospital The fastest chance is 1 hour, and the surgery can be completed in 3-4 hours in an outside consultation. 2 is interventional surgery, which is also commonly known as stent surgery, the procedure is safer and can be completed under local anesthesia without a major incision, 1-2 5cm long incisions in the groin can be completed, and this type of surgery can be carried out in some primary hospitals. However, this procedure requires high anatomical conditions, and some barely do stenting is not as good as open surgery, and it is costly. However, for patients with poor cardiopulmonary function and systemic status, intervention is preferred.
