Persistent symptoms after endovenous thermal ablation may suggest proximal venous outflow obstruction

ConclusionsApproximately 15% of patients undergoing vein stent placement for chronic PVOO have an antecedent history of superficial venous disease and EVTA. PVOO should be considered and the patient evaluated accordingly if symptoms persisted or recurred after EVTA. Vein stent placement among these patients with PVOO will result in further symptomatic relief, but complete symptomatic relief is not observed in everyone. The algorithm for the management of these patients warrants further investigation.
