Pseudo-no-reflow phenomenon in carotid artery stenting using FilterWire EX: successful recovery by aspiration thrombectomy.
Distal protection devices such as FilterWire EX have been widely used in carotid artery stenting, however, the large amount of atherothrombotic debris entrapped in the filter could reduce or stop antegrade flow. We present a case of pseudo-no-reflow phenomenon after postdilatation of the stent in a patient with asymptomatic carotid artery stenosis. After several passes using an Export Aspiration catheter, normal flow in the internal carotid artery was restored. Aspiration thrombectomy can successfully recover pseudo-no-reflow phenomenon.
