摘要
目的通过B超检查观察老年人腹主动脉瘤自然发展规律.方法回顾性总结分析27例经超声诊断并随访10年以上的老年腹主动脉瘤患者的临床特征、超声特点及发展变化规律,并进行统计学分析.结果1989年1月至2005年1月我院体检的老年人中,超声诊断腹主动脉瘤34例,其中经超声检查随访10年以上且持续存在的27例.27例中,腹主动脉瘤大小为2.5～6.6cm,平均每年增长(0.14±0.01) cm.其中17例(63.0%)有附壁血栓形成,形成时间在诊断后的(3.9±2.0)年,血栓每年增长(0.21±0.05)cm.结论老年人腹主动脉瘤随增龄增长缓慢,半数以上形成附壁血栓;较少发生瘤体破裂及附壁血栓脱落.
Objective To study the regularity of occurrence and development in the elderly with AAA. Methods Twenty-seven elderly cases with abdominal aortic aneurysm（AAA） were analyzed and followed up with ultrasound for ten years. Results The AAA diameters were 2.5～6.6cm, with the average in crease of（0.14±0.01）cm/ year. Intraluminal thromi（ILT） were found in 63.0% of all the patients. ILT were found （3.9±2.0） years after the AAA diagnosis with the average in crease of（0.21±0.05）cm/year. Conclusions The size of AAA in the elderly is slowly enlarged to varying degree with ageing. ILT are found in more than half of all the patients. A few cases of AAA are found ruptured and a few eases of ILT exfoliated.
