Peri-procedural outcome of series of 104 carotid artery stenting procedures

BackgroundManagement of carotid artery stenosis is considered an important strategy for stroke prevention. Carotid artery stenting (CAS) has been introduced as an acceptable alternative to surgical carotid endarterectomy (CEA) in the treatment of internal carotid artery (ICA) stenosis.ObjectiveAssessment of peri-procedural outcome of CAS in 104 consecutive procedures.MethodsThe study included 104 consecutive CAS procedures. Included patients had ⩾50% ICA stenosis in the symptomatic group and ⩾70% stenosis in the asymptomatic group. Procedures were performed in cath. labs of Catania and Ragusa hospitals-Italy.ResultsIncluded procedures were done in 100 consecutive eligible patients with ICA stenosis. Four patients had undergone CAS procedures in both sides in 2 separate sessions. Patients were 71 males and 29 females, mean age was 71.9 ± 7.85 years, and 21 patients were ⩾80 years old (octogenarians). The majority of patients had asymptomatic ICA stenosis (76%) and was diagnosed accidentally during medical checkup. Twenty-four patients had symptomatic ICA stenosis (ipsilateral TIA or stroke). Technical success was obtained in 103 procedures (99%). Embolic protection devices were used in all succeeded cases. Combined cerebrovascular events had occurred in 5 patients with estimated rate = 4.8%. No cases of amaurosis fugax, MI or death had occurred. Adverse events was 4.1% in the symptomatic group and 1.3% in the asymptomatic group with no significant statistical difference (P = 0.064).ConclusionCAS with EPDs seems a feasible and safe procedure and could be performed with an acceptable rate of periprocedural adverse events.
