Unilateral leg swelling is most frequently the result of venous hypertension based on deep vein thrombosis. The suspicion of a pelvic vein thrombosis requires direct thrombus detection and exclusion of the spectrum of differential diagnoses, especially after pelvic surgery. In this paper we report a case of unilateral leg swelling with complex arteriovenous vascular pathology after minimally invasive disc surgery. The differential diagnosis and interventional therapy are discussed.
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.
