Background: Carotid artery stenting (CAS) with distal filter protection allows continuous cerebral perfusion, although it is associated with a greater risk of cerebral ischemic complications than other protection systems. To reduce cerebral ischemic complications, CAS was performed under combined cerebral protection using both flow reversal (FR) and a distal filter. Methods: Fifty-six stenoses of 52 patients were treated with CAS using the combined protection of FR and a distal filter, with intermittent occlusion of both the common carotid artery (CCA) and the external carotid artery. The blood flow was reversed into the guiding catheter to the central venous system via an external filter, which collected the debris. Clinical outcomes, the rates of capturing visible debris, and new ischemic signals on diffusion-weighted magnetic resonance imaging (DWI-MRI) were evaluated. Results: The overall technical success rate was 92.9% (52/56). Successful stent deployment was achieved in 100% (56/56) of the cases. No procedural-related emboli causing a neurologic deficit were observed. In 38.5% (20/52) of the cases, visible debris were captured by only the external filter, and in 17.3% (9/52), visible debris were captured by both external and distal filters. In no case was visible debris noted in only the distal filter. New ischemic signals on DWI-MRI were detected in 9.6% (5/52). The 30-day myocardial infarction, stroke, and death rates were 0%. Conclusions: The additional use of a distal filter captures emboli in 17.3% of cases, and because the occlusion is only intermittent, the procedure is potentially applicable even in those who cannot tolerate prolonged balloon occlusion of the CCA.
