Although randomized data remain inconclusive, invasive endovenous therapy is increasingly favored in patients with extensive iliocaval or iliofemoral deep vein thrombosis (DVT) to reduce the rates of postthrombotic syndrome. Previously, pharmacomechanical thrombectomy was the therapy of choice, but the Inari ClotTriever device is an appealing, purely mechanical, alternative. It may reduce bleeding risk, intensive care unit admission, and the need for multiple procedures when compared with traditional thrombolysis. We present a series of 18 patients treated with the ClotTriever for extensive iliocaval or iliofemoral DVT.

The Inari ClotTriever is a percutaneous mechanical thrombectomy system consisting of an expandable nitinol collection bag that is dragged along the vein wall, separating and capturing thrombus for collection into the retrieval sheath. We retrospectively reviewed all patients …
