This prospective cohort study was taken to determine whether transcervical carotid artery stenting (CAS) with internal carotid artery (ICA) flow reversal is associated with a lower incidence of embolization and femoral access complication when compared with protected, transfemoral CAS in selected, high-risk patients. From 2002 to October 2004, the authors performed 55 carotid stentings and angioplasties. Among the 24 cases via transfemoral approach, 1 developed transient ischemic attack (TIA), 1 stroke, 1 asystolic cardiac arrest, 2 groin hematoma, 2 technical failure, and 1 restenosis. Among the 31 cases via transcervical approach, 2 patients developed TIAs, 4 bradycardia, 2 cervical hematoma, and 3 technical failures leading to open conversion and carotid endarterectomy. Transcervical CAS with ICA flow reversal eliminates the risk of aortic arch emboli, provides cerebral protection during predeployment manipulation across the carotid lesion, negates preprocedure mapping of the aortic arch configuration, and surpasses difficult aortic arch or transfemoral access.
