Objective.探讨肾下型腹主动脉瘤（AAA）的生长速度及影响其进展的因素。设计观察性，纵向，前瞻性研究。患者和方法。我们对两组直径<5cm的AAA患者进行了随访。组I（AAA 3-3.9 cm，n=246）每年进行一次超声扫描。第11组（AAA 4-4.9 cm，n = 106）接受6个月CT扫描。我们纳入了352名患者（333名男性和19名女性），平均随访55.2 +/- 37.4个月（6.3-199.8）。第11组的平均生长率显著更高（4.72 +/- 5.93 vs 2.07 +/- 3.23 mm/4年; p < 0.0001）。第11组动脉瘤快速扩张（> 4 mm/年）的患者百分比更高（36.8 vs. 13.8%; p < 0.0001）。经典的心血管危险因素不影响组I中AAA的增长率。慢性肢体缺血与缓慢扩张相关（
Objective. To study the growth rate and factors influencing progression of small infrarenal abdominal aortic aneurysms (AAA). Design. Observatiotial, longitudinal, prospective study.Patients and methods. We followed patients With AAA < 5 cm in diameter in two groups. Group I (AAA 3-3.9 cm, n=246) underwent annual ultrasound scans. Group 11 (AAA 4-4.9 cm, n = 106) underwent 6-monthly CT scans.Results. We included 352 patients (333 men and 19 women) followed for a mean of 55.2 +/- 37.4 nionths (6.3-199.8). The mean growth rate was significantly greater in group 11 (4,72 +/- 5.93 vs. 2.07 +/- 3.23 mm/4year; p < 0.0001). Group 11 had a greater percentage of patients with rapid aneurysm expansion (> 4 mm/year) (36.8 vs. 13.8%; p < 0.0001). The classical cardiovascular risk factors did not influence the AAA growth rate in group I. Chronic limb ischemia was associated with slower expansion (
