Clinical challenges in asymptomatic chronic aortoiliac occlusive disease

Abstract

Asymptomatic aortoiliac occlusive disease, while less common compared to other peripheral arterial diseases, presents unique clinical challenges. Our center recently encountered a case involving a patient with chronic occlusion of the distal abdominal aorta and bilateral iliac arteries. Remarkably, this patient had developed an extensive network of collateral circulation, effectively compensating for the reduced blood supply to the pelvic and lower limb areas. This adaptive physiological response resulted in the patient exhibiting no significant clinical symptoms. To reveal the most effective diagnostic and treatment strategies for asymptomatic peripheral artery disease patients to avoid complications and other challenges, more clinical studies are needed in the future.
