Diagnostic transcatheter aspiration for pulmonary artery tumor embolism using an INARI Triever aspiration catheter.

Pulmonary artery tumor embolism is a rare phenomenon and its diagnosis is important because of a poor prognosis. We report a 20-year-old male with history of metastatic osteosarcoma who presented with acute pulmonary embolism. He was urgently taken to the catheterization laboratory and underwent transcatheter aspiration of pulmonary artery mass using an INARI Triever aspiration catheter. Pathology of the aspirated specimen lead to the diagnosis of pulmonary artery tumor embolism, not thrombus. This case highlights the diagnostic utility of transcatheter aspiration for the pulmonary artery tumor embolism.
