Transfemoral recanalization of occluded TIPS

Abstract

Purpose: To report the safety and efficacy of percutaneous transfemoral venous recanalization of occluded intrahepatic portosystemic stents (TIPS) in cases where the transjugular approach is not feasible. Materials and Methods: Between 2000 and 2020, 8 patients with occluded TIPS underwent recanalization via a percutaneous transfemoral venous access. Prior recanalization via a typical transjugular approach was attempted in all cases. Primary technical success was defined as successful crossing of the occlusion. Secondary technical success was defined as the rate of successful TIPS recanalization. Periprocedural complications were evaluated to assess procedural safety. Results: In 8/8 patients transfemoral venous TIPS recanalization was successful. No procedure-related complications were observed. Conclusions: The transfemoral venous approach is a safe and efficient alternative for TIPS recanalization in cases where the transjugular approach is not feasible.
