Pulse-spray catheter-directed thrombolysis with monteplase for IVC filter-associated thrombosis after massive pulmonary embolism requiring VA-ECMO: a case report

If thrombus progression is observed after IVC filter placement, pulse-spray CDT using monteplase may help prevent complications, such as difficulty in filter retrieval and development of post-thrombotic syndrome, without any bleeding, particularly when urokinase is unavailable.
