Abstract
Summary: An estimated 237 million people suffer from peripheral arterial disease (PAD), which is associated with high morbidity and mortality, and prevalence is still increasing. Currently, we do not have any randomized trials that compare screening to no screening specifically for PAD in the general population. Presently, PAD screening is not generally established. This systematic review gives an overview of relevant literature and guidelines. Screening usually focuses on ankle-brachial index (ABI)-measurement, which enables detection of asymptomatic and symptomatic PAD, but has limitations in diabetics. There are no sufficient data on PAD screening. Guideline recommendations are heterogeneous. While some advocate no screening until better data are available, most recommend selective screening despite insufficient data on morbidity and mortality reduction in consequence of screening. We support the only evidence-based screening strategy for PAD: combined screening for abdominal aortic aneurysm (AAA), PAD and arterial hypertension in men aged 65–74 according to the VIVA study. We additionally suggest a new simple three-step screening strategy for symptomatic PAD in all individuals aged 40 and older, who see a general practitioner: Asking one question (“Do you have pain or cramps in the legs during normal walking?”) followed by physical examination (normal lower extremity pulse status?) in those, whose answer is “yes”, and ABI measurement unless all pulses are normal.
