“Popliteal artery aneurysms (PAAs) are the most common peripheral arterial aneurysms, defined as aneurysms outside the aortoiliac system or the brain, accounting for 70% of all peripheral arterial aneurysms. They are more common in men (95%) and tend to occur in the sixth and seventh decades of life. Few modern studies have been performed on the natural history of PAAs, and many of these were retrospective reviews of surgical patients. As such, the timing and details of PAA management remain nuanced.”

“These guidelines focus on PAA screening, indications for intervention, choice of repair strategy, management of asymptomatic and symptomatic PAAs (including those presenting with acute limb ischemia), and follow-up of both untreated and treated PAAs. They offer long-awaited evidence-based recommendations for physicians taking care of these patients.”
