The true incidence of popliteal entrapment cannot be estimated due to a lack of awareness, misdiagnosis, and the relative rarity of presentation. Likely, only the most severe cases present for evaluation and workup and obtain a true diagnosis. We are presenting four legs of popliteal entrapment in two patients at different times.
A persistent sciatic artery (PSA) is a rare vascular anomaly. It can cause complications, including acute and chronic limb ischemia, aneurysm formation, and compression of adjacent tissues during early embryonic development, the sciatic artery usually disappears when the superficial femoral artery has developed properly. PSA is usually an incidental finding and is exceedingly rare to find bilaterally. We are presenting a rare case of unilateral PSA aneurysm presented as an episode of recurrent acutely ischemic limb.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
