[Surgical treatment of atherosclerotic aneurysms of the thoracic aorta].
To determine the problem of the surgical treatment of atherosclerotic aneurysm of thoracic aorta, we reviewed our experiences with 113 consequtive patients who underwent thoracic aortic aneurysmectomy from January 1983 to December 1985. Fifty-two patients had atherosclerotic aneurysms and 61 patients had aneurysm with other etiologies. Hospital mortality was 19% in former group and was higher than in the latter group (6.5%). Especially, the mortality was the highest (50%) among the patients who required the intraoperative clamping of the arch vessels. Many complications related to atherosclerosis, such as atheroemboli, bleeding due to wall weakness and etc, was found among the patients died soon after the surgery. Also, age over 70 and renal or respiratory dysfunction were major risk factors to determine the operative death. On the other hand, asymptomatic ischemic heart disease and cerebrovascular disorders of three months after the onset were not significant determinant. It was concluded that the surgical indication should be contemplated with extreme care specifically among the patients with such risk factors.
