case_images: Pre-thrombectomy venogram. (A) The initial venogram demonstrates significant thrombus in the iliac, femoral, and popliteal veins; (B) The pre-thrombectomy venogram shows extensive clot formation and collateral veins; (C) A large volume clot is present with collaterals in the venous system and an IVC filter already in place.. IVC: inferior vena cava

case_images: The venogram showed a large thrombus involving the iliac, femoral, and popliteal veins and extensive collateral formation (Figure 1).
case_images: Acute, subacute, and chronic thrombus were retrieved over an 80-minute period using the Inari FlowTriever system

case_images: Next, the Inari thrombectomy devices (Inari Medical, Irvine, California), including Triever20 and Triever16, were placed over the wire, and a total of 15 "Whoosh" aspirations, over 80 minutes, were used to retrieve an extraordinary amount of acute, subacute, and chronic thrombus (Figure 2).
case_images: Post-thrombectomy venogram. (A) A post-thrombectomy venogram showing brisk flow in the venous system and resolution of collaterals; (B) brisk venous flow in the superficial femoral vein; (C) brisk flow in the common femoral vein. No clot is seen post-treatment.
