Endovascular treatment of chronic ilio-femoral vein obstruction with extension below the inguinal ligament in patients with post-thrombotic syndrome.

•Type of Research: Single-center, retrospective, non-randomized cohort study•Key Findings: Poor inflow and Villalta scale > 15 points at admissionwere predictive for in-stent occlusion over the follow-up. Proper inflow ensures the patency of the treated iliac axis.•Take home Message: The use of a dedicated venous stent across the inguinal ligament is feasible and safe, with acceptable primary and secondary patency rates and a low rate of complications in the early and medium term.
