【摘要】 目的 探讨影响老年主动脉瘤转归的相关因素。方法 总结8例老年主动脉瘤临床资料,胸主动脉瘤2例,腹主动脉瘤6例,平均年龄(77.9±5.74)岁,病程0.5~12 年,血压<21.3/12 kPa 6例,>21.3/12 kPa 2例,瘤体直径<5.0 cm 1例,5.0~7.0 cm 4例,>7.0 cm 3例,瘤壁厚度<2.0 cm 5例,2.0~4.0 cm 3例。结果 死亡3例中2例死于瘤体破裂出血。结论 血压、瘤壁厚度、瘤体迅速增大,应力作用及并存严重心脏病是影响老年主动脉瘤转归的主要相关因素。 【关键词】 主动脉瘤 血压 老年

【Abstract】 Objective Attempts were made to find prognostic factors in aortic aneurysm.Method The clinical and examinat findings of 8 cases with aortic aneurysm were analyzed,2 of 8 were thoracic aneurysm, 6 of 8 abdominal aneurysms, age range as (77.9±5.74) years old, the disease history 0.5~12 years.There were 6 cases with blood pressure<21.3/12 kPa and 2 cases≥21.3/12 kPa, 1 patient had aneurysm range below 5.0 cm, 4 had 5.0~7.0 cm and 3 had over 7.0 cm.Results A follow-up study showed that 2 of 8 were death duing to rupture of the aneurysm.Conclusion It is suggested that following factors were related to propect of aneurysm: the blood pressure, thickness of aneurysm wall, the range of aneurysm increase fast, and so on. 【Key words】 Aneurysm Blood pressure Elder
主动脉瘤是有潜在危险性的严重心血管疾病。主动脉瘤老年患者的临床过程和转归有很大差异,有的异常凶险迅速危及生命。有的病变隐袭,长期呈亚临床型。为了探讨其中的规律性,提高临床防治水平,现将我们自1984年~1996年收治的8例65岁以上,经影像检查确诊为主动脉瘤老年病人转归的相关因素分析报道如下。
临床资料 8例老年男性主动脉瘤患者,年龄69~88岁,平均(77.9±5.74)岁,经超声、计算机断层扫描(CT)、核磁共振(MRI)联合诊断为胸主动脉瘤2例,腹主动脉瘤6例,临床特点详见表1。影像学检查中瘤体直径<5.0 cm者1例,5.0~7.0 cm者3例,>7.0 cm者3例。瘤壁厚度<2.0 cm者5例,2.0~4.0 cm者3例。表2随访0.5~12 年,生存者5例,其中1例行腹主动脉切除,人造血管移植术,死亡3例,1例死于肺癌术后肺内感染,心源性休克,2例死于动脉瘤破裂出血。3例死亡者的平均年龄(76.3±10.2)岁。平均确诊(患病)年限(1.8±1.89)年。
讨 论 主动脉瘤破裂是一最凶险的心血管急症。从主动脉瘤的生物特性及其自然发展趋势来看,日久之后必然会发生破裂,决定预后的相关因素有许多,主要有以下几点。 1.血压与预后关系密切 本文2例因瘤体破裂出血死亡者既往有高血压病史,平时血压控制不理想,血压波动幅度最高值≥21.3/12 kPa。5例生存者中4例无高血压病史,1例虽有高压病史,但平时血压波动幅度小,[1] [2] [3] 下一页 上一个医学论文: 运动心肺功能测验远期追踪 下一个医学论文: 常温体外循环温血心停搏液持续灌注心肌保护的实验研究
