TREATMENT OF DISSECTING AORTA

Two hundred and twenty cases of aortic aneurysms were hospitalized in our department. There were forty-three cases of dissecting aneurysms and twenty-six of them had surgical treatment. They were classified as eight cases of type I, two of type II, and sixteen of type III by DeBakey. As a rule,surgery is the method of treatment for these patients. At first, after reducing the blood pressure to about 100ｰ120mmHg, surgery should be done one or more months later. The cases of type I should be operated on earlier. Main aortic branches are often occluded and it is necessary to clarify them by means of aortography or other methods. For example, when the right renal artery originates be operated on earlier. Main aortic branches are often occluded and it is necessary to clarify them by means of aortography or other methods. For example, when the right renal artery orignaites from true lumen and pseudo-lumen supplies the blood flow to the left side, it is thought to be better that fenestration at renal arterial level and reconstruction of the abdominal aorta first, and then entry in the thoracic aorta should be treated. General complications such as hypertension, renal failure,diabetes mellitus and so on are often present and strict pre- and postoperative care is necessary. The operative result is not satisfactory yet, but it is getting better day by day.
