腹主动脉瘤110例临床特点及预后分析

目的 探讨腹主动脉瘤的临床特点及影响预后的可能因素.方法 回顾性分析我院确诊的110例腹主动脉瘤患者的临床资料,其中肾下型109例,肾上型1例.应用Cox比例风险回归模型分析各相关因素与预后的关系.结果 110例患者中,男性84例（76.4％）,女性26例（23.6％）,男女比例为3.23：1,中位年龄74岁.11例（10.0％）患者以腹主动脉瘤破裂作为首发症状,其中男性10例,女性1例,男性中破裂率（11.9％）高于女性（3.8％）.Cox比例风险回归模型分析显示瘤体直径大的患者预后较差,手术治疗可改善患者预后.结论 早期诊断、密切随访、及时手术可改善腹主动脉瘤患者预后.

Clinical features and prognostic analysis in 110 patients with abdominal aortic aneurysm

Objective To investigate the clinical features and relevant prognostic factors in pa- tients with abdominal aortic aneurysm（AAA）. Methods The clinical records of 110 patients （ 109 infra- renal AAA patients and 1 suprarenal AAA patient） in Sun Yat-sen memorial hospital from 2000 to 2011 were retrospectively analyzed. Cox regression analysis was used to evaluate the relationship between risk factors and prognosis. Results The median age of the studied patients （ 84 males and 26 females） was 74 years old. Rupture of abdominal aortic aneurysm was the first symptom in 11 patients（ 10 males and 1 fe- male）. The rupture rate in the male AAA patients was significantly higher than that in ＇the female＇ s （ 11.9% vs 3.8% ,P 〈 0.05 ）. Cox regression analysis showed that the aneurysm with larger diameter had poorer prognosis, and surgical operation could improve prognosis of the disease. Conclusion Early diag- nosis,follow-up closely and operation timely are the essential measures for improving prognosis in AAA patients.
