Occult popliteal artery stenosis masquerading as atheroemboli in a patient with previous knee replacement (original) (raw)

This case report discusses the rare occurrence of occult popliteal artery stenosis that was misdiagnosed as atheroemboli in a patient with a previous knee replacement. Despite initial normal angiograms, persistent symptoms prompted further investigation using noninvasive imaging techniques and oblique angiography, ultimately revealing a significant stenosis obscured by the prosthesis. The findings underscore the importance of comprehensive physical examinations and noninvasive testing in patients with symptomatic vascular disease, demonstrating that initial imaging may overlook critical pathology.
