Catheter thrombectomy using a 3-loop EN Snare successfully fragmented an organized thrombus and reduced mean pulmonary artery pressure from 37 mmHg to 19 mmHg in a patient with acute massive pulmonary embolism.

A 3-loop snare device combined with a guiding catheter under percutaneous cardiopulmonary support can successfully remove organized thrombus in acute-on-chronic massive pulmonary embolism when standard catheter thrombectomy fails.
Snare thrombectomy may succeed where standard devices fail in massive PE; leaves open its broader applicability and risks.
A 70-year-old man presented with acute massive pulmonary embolism (PE). His clinical condition deteriorated despite regular heparin and thrombolytic agent treatment, and he eventually developed cardiogenic shock. A thrombus originating from the inferior vena cava was detected and acute-on-chronic embolization resulted, with an unusual clinical course. Aggressive catheter thrombectomy with pigtail rotation failed to fragment the organized thrombus, but it was successfully removed by a 3-loop snare device combined with guiding catheter under percutaneous cardiopulmonary support.

Hsu et al. (2008) conducted a case report in Acute-on-chronic massive pulmonary embolism (n=1). 3-loop EN Snare combined with 8Fr PTCA guiding catheter was evaluated on Hemodynamic improvement (pulmonary artery pressure reduction). Catheter thrombectomy using a 3-loop EN Snare successfully fragmented an organized thrombus and reduced mean pulmonary artery pressure from 37 mmHg to 19 mmHg in a patient with acute massive pulmonary embolism.
