[DJR-127 1.0 CE] Carotid Artery Stent Placement and Carotid Endarterectomy: A Challenge for Urgent Treatment after Stroke—Early and 12-Month Outcomes in a Comprehensive Stroke Center


Purpose: To compare feasibility, 12-month outcome, and periprocedural and postprocedural risks between carotid artery stent (CAS)
placement and carotid endarterectomy (CEA) performed within 1 week after transient ischemic attack (TIA) or mild to severe stroke
onset in a single comprehensive stroke center.

Materials and Methods: Retrospective analysis of prospective data collected from 1,148 patients with ischemic stroke admitted to a single stroke unit between January 2013 and July 2015 was conducted. Among 130 consecutive patients with symptomatic carotid stenosis, 110 (10 with TIA, 100 with stroke) with a National Institutes of Health Stroke Scale (NIHSS) score < 20 and a prestroke modified Rankin Scale (mRS) score < 2 were eligible for CAS placement or CEA and treated according to the preference of the patient or a surrogate. Periprocedural (< 48 h) and postprocedural complications, functional outcome, stroke, and death rate up to 12 months were analyzed.

Results: Sixty-two patients were treated with CAS placement and 48 were treated with CEA. Several patients presented with moderate
or major stroke (45.8% CEA, 64.5% CAS). NIHSS scores indicated slightly greater severity at onset in patients treated with a CAS vs
CEA (6.6 ± 5.7 vs 4.2 ± 3.4; P ¼.08). Complication rates were similar between groups. mRS scores showed a significant improvement
over time and a significant interaction with age in both groups. Similar incidences of death or stroke were shown on survival analysis. A
subanalysis in patients with NIHSS scores  4 showed no differences in complication rate and outcome.

Conclusions: CAS placement and CEA seem to offer early safe and feasible secondary stroke prevention treatments in experienced
centers, even after major atherosclerotic stroke.
