Single-Center Experience Using the Inari FlowTriever for Mechanical Thrombectomy of Extrapulmonary Thrombosis: A Case Series

Abstract

The FlowTriever Gen 1 System (Inari Medical, Irvine, California, United States) is a mechanical thrombectomy device designed to extract thrombus from the pulmonary arteries, but is U.S. Food and Drug Administration approved for use in any artery or vein. From 2019 to 2020, three consecutive patients with extrapulmonary thrombosis involving the inferior vena cava (IVC), renal, gonadal, and femoropopliteal veins were treated with the device. The FlowTriever large-bore aspiration catheter was partially successful in removing IVC, renal and lower extremity vein thrombus. Zero major or minor adverse events occurred. Several technical and therapeutic insights were gained from this preliminary experience.
