  1. Abdominal aortic aneurysm screening in elderly males with atherosclerosis : The value of physical exam.

    Article, Communication - En anglais

    Annual Meeting of the Southern California Chapter, American College of Surgeons. Santa Barbara, California USA, 1996/01/19.

    The purpose was 1) To assess the prevalence of abdominal aortic aneurysms (AAA) in elderly males with atherosclerosis and 2) to evaluate the value of physical exam (PE) by a vascular surgeon in detecting AAA.

    A total of ninety-six males older than 55 years referred to vascular surgery clinic with atherosclerotic disease were screened prospectively with PE by a vascular surgeon, followed by ultrasonography (US).

    Atherosclerosis was documented by ankle brachial index and duplex US.

    Patients who had recently undergone a vascular procedure, aortography, laparotomy, abdominal computed tomography, or US were excluded.

    Mean age was 67 years.

    Patients were 67 per cent Caucasian, 32 per cent black, and 1 per cent Hispanic.

    Presenting complaints were related to claudication (83%), carotid disease (19%), both (3%), and subclavian stenosis (1%). Patient characteristics included cigarette smoking (85%), hypertension (67%), cardiac disease (51%), diabetes (45%), stroke (18%), and chronic obstructive pulmonary disease (8%). One (1%) 3.7 cm AAA was detected by US.

    Sensitivity of PE was 100 per cent and specificity 92 per cent.

    Twenty-two (23%) patients were too obese for us to feel the aortic pulse.

    Screening cost was $14,250.

    The prevalence of AAA in this population is very low.

    AAA screening should be reserved for patients with a positive PE or who are too obese for the examiner to feel the aortic pulse.
