We aimed to explore the feasibility of a nurse-supervised aneurysm screening program to identify any independent risk factors for abdominal aortic aneurysm (AAA) formation in high-risk patients.
We conducted a prospective observational study of 90 male patients in a university- affiliated hospital in southern Ontario. The patients were prospectively evaluated and all underwent abdominal ultrasonography, with the main outcome measure being detection of an AAA.
AAAs were identified in 18 patients (20%) and had a mean diameter of 3.6 (range 2.8-6.0) cm. A separate analysis was performed to identify risk factors for the presence of an aneurysm. The presence of carotid artery disease proved to be the only statistically significant independent predictor of the presence of AAA (odds ratio 2.23, 95% confidence interval 1.76-2.56).
This study confirms the feasibility of a nurse-supervised AAA screening program, and on the basis of these results we recommend ultrasonographic screening for AAA in patients with a history of carotid artery disease.
我们旨在探讨由护士监督的动脉瘤筛查项目在识别高危患者腹主动脉瘤（AAA）形成的任何独立危险因素方面的可行性。
我们在安大略省南部一家大学附属医院对90名男性患者进行了一项前瞻性观察研究。对患者进行前瞻性评估，所有患者均接受腹部超声检查，主要结局指标是腹主动脉瘤的检测。
在18名患者（20%）中发现了腹主动脉瘤，平均直径为3.6（范围2.8 - 6.0）厘米。进行了一项单独分析以确定动脉瘤存在的危险因素。颈动脉疾病的存在被证明是腹主动脉瘤存在的唯一具有统计学意义的独立预测因素（比值比2.23，95%置信区间1.76 - 2.56）。
本研究证实了由护士监督的腹主动脉瘤筛查项目的可行性，基于这些结果，我们建议对有颈动脉疾病史的患者进行腹主动脉瘤超声筛查。
