Abstract
We report a case of endovascular recanalization of complete thrombotic occlusion of the inferior vena cava (IVC) and bilateral iliac veins using the architectural knowledge of the in situ permanent IVC filter in a 23-year-old male. The infrarenal permanent IVC filter was TRAPEASE permanent vena cava filter (Cordis) placed at an outstation hospital for pulmonary embolism. Being permanent variant of filter, percutaneous removal was not possible. The patient had severe venous claudication and an attempt to recanalize the blocked filter was considered, in view of the age no justifiable indication for a long-term filter. After pharmacomechanical catheter-directed thrombolysis, there was residual focal flow-limiting thrombus within the filter. The design of the Trapease Cordis filter was instrumental in our decision to attempt to recanalize the filter in situ using 2 parallel stents with the filter struts as anchoring pillars in a double-barrel alignment. In similar cases of persistent Trapease filter-related thrombotic occlusion of the IVC, this double barrel in situ recanalization shall be a viable alternative to the well-described technique of crushing the filter and recanalizing it with a single stent.
