  A 56-YEAR-OLD FEMALE WITH DEEP VEIN THROMBOSIS (DVT) UNDERWENT A THROMBECTOMY IN THE LEFT LEG WITH THE INARI FLOWTRIEVER SYSTEM ON (B)(6) 2023. THE PATIENT ALSO HAD AN INFERIOR VENA CAVA (IVC) FILTER PLACED 90 DAYS PRIOR. THE TRIEVER20 (T20) WAS DEPLOYED AND 5 ASPIRATIONS WERE PERFORMED IN THE LEFT LEG WITH APPROXIMATELY 225 CC OF BLOOD RETURNED VIA THE INARI FLOWSAVER DEVICE TO THE RIGHT LEG (POPLITEAL ACCESS). A PENUMBRA INDIGO SYSTEM CAT 8 DEVICE WAS THEN USED TO CLEAR COLLATERAL THROMBUS. THE T20 WAS RE-INSERTED TO CLEAR THROMBUS FROM THE FEMORAL-POPLITEAL, COMMON FEMORAL, AND EXTERNAL ILIAC VEINS. HOWEVER, THE T20 BECAME CAUGHT IN THE VESSEL. THE SURGEON MADE VARIOUS ATTEMPTS TO REMOVE THE T20, INCLUDING USE OF VASODILATORS, LUBRICANTS, AND BALLOONING, BUT THE T20 WAS UNABLE TO BE REMOVED. BEFORE THE SECOND BALLOONING ATTEMPT, THE T20 SHEARED AT THE POPLITEAL ACCESS. EVENTUALLY, CARDIOTHORACIC SURGERY INTERVENED TO PERFORM A VENOUS CUTDOWN ON THE COMMON FEMORAL VEIN AND THE T20 WAS REMOVED. THE THROMBECTOMY WAS SUCCESSFUL IN REMOVING 90% OF THE CLOT BURDEN AND THE PATIENT MADE A FULL RECOVERY.
