The purpose of this study was to evaluate the long-term prognosis of unoperated thoracic aortic aneurysms, and to detect the risk factors which determine the prognosis of unoperated patients. The subjects were 52 unoperated patients with 58 thoracic aortic aneurysms (22 of the ascending aorta, 36 of the descending aorta or the aortic arch) and 38 with abdominal aortic aneurysms. The survival rates of the patients with ascending aortic aneurysms at 3 years and 5 years and those of the patients with descending aortic aneurysms at 5 years were significantly higher than those of the patients with abdominal aortic aneurysms. The risk factors for rupture of thoracic aortic aneurysms were the large size of aneurysms and non-management by the cardiologist and the risk factors for death unrelated to the aneurysms were patient age, male gender and non-management by the cardiologist.
本研究的目的是评估未经手术治疗的胸主动脉瘤的长期预后，并检测决定未经手术治疗患者预后的危险因素。研究对象为52例未经手术治疗的患者，其中有58个胸主动脉瘤（升主动脉22个，降主动脉或主动脉弓36个）以及38例腹主动脉瘤患者。升主动脉瘤患者3年和5年的生存率以及降主动脉瘤患者5年的生存率显著高于腹主动脉瘤患者。胸主动脉瘤破裂的危险因素是动脉瘤尺寸较大和未由心脏病专家进行管理，与动脉瘤无关的死亡危险因素是患者年龄、男性性别以及未由心脏病专家进行管理。
