Use of microvena snare catheter in non-ST elevation myocardial infarction due to saphenous vein graft occlusive thrombi.

A 75-year-old man presented with acute coronary syndrome; he had a saphenous vein graft thrombosis. Percutaneous coronary intervention of bypass graft vessels is more challenging due to a higher incidence of periprocedural distal micro-emobilization and myocardial infarction. Current guidelines for percutaneous coronary intervention advocate the use of distal embolic protection devices, especially in patients with large thrombus burden, undergoing percutaneous intervention for vein graft disease. This patient was treated by manual aspiration of graft thrombus using a microvena catheter and successful clot removal was achieved. There are yet no best available therapeutic options for patients undergoing percutaneous coronary intervention of saphenous vein graft lesions.
