A patient in his 40s, who had experienced acute deep vein thrombosis (DVT) of his left leg 13 years ago, developed acute DVT of his right leg due to an inferior vena cava filter (IVCF) thrombotic occlusion. A thrombus extended from just below the IVCF to the bilateral femoral veins. Given the limited availability of urokinase and the strict guidelines for the proper use of the Indigo CAT8 in Japan, we first performed catheter-directed thrombolysis with alteplase for 2 days, followed by aspiration with the CAT8 catheter after confirming the absence of an IVC thrombus. Finally, we successfully retrieved this IVCF, implanted 13 years earlier, using the bidirectional technique.
