Why the study?
Clot-in-transit is a life-threatening emergency with high mortality and risk of cardiopulmonary collapse requiring prompt interventions.
Percutaneous aspiration thrombectomy is a promising and successful approach for treating high-risk patients with cardiopulmonary thrombus-in-transit.
May support percutaneous aspiration for select IVC filter-related CIT; leaves open safety and efficacy versus alternatives.
Clot-in-transit (CIT) is a life-threatening emergency that occurs in about 25 000 patients annually in the United States and is associated with high mortality due to the potential for rapid cardiopulmonary collapse, requiring prompt interventions. We present a case of a right atrial clot-in-transit extending from an existing inferior vena cava (IVC) filter in a patient with pulmonary embolism who had a successful aspiration thrombectomy using a percutaneous catheter-based system, highlighting the benefit of this technology in treating cardiopulmonary thrombi, especially in high-risk patients.
