Carotid artery stenting in unfavorable vascular anatomy: Effect of embolic protection filter use on periprocedural complications.

Evaluation of vascular anatomy before carotid artery stenting is important to decide on the technical procedure to be applied in the procedure. The use of EPD in unfavorable anatomy does not reduce periprocedural neurological events. Instead, it results in technical difficulties, prolongs the duration of procedure, and leads to arterial vasospasm. Considering the high periprocedural events in this study, carotid endarterectomy may be a better alternative to endovascular treatment in patients with unfavorable carotid artery anatomy.
