Unprotected Carotid Artery Stenting Compared to Carotid Endarterectomy in a Community Setting

Abstract

Purpose:

To evaluate the feasibility and safety of carotid artery stenting (CAS) performed by a dedicated multidisciplinary team in a community hospital.

Methods:

Forty-nine patients (30 men; mean age 74.3 ± 7.4 years, range 51–88) with 14 symptomatic and 35 asymptomatic >50% carotid stenoses were enrolled into the study and treated with self-expanding stents without cerebral protection. The patients were evaluated at 30 days for death, neurological sequelae, and length of stay. A contemporaneous group of 140 patients (80 men; mean age 72.3 ± 7.7 years, range 43–89) undergoing carotid endarterectomy (CEA) was used for comparison of the outcome measures. Owing to crossover of failed CAS patients to the CEA group, the data were analyzed according to intention-to-treat and treatment-received.

Results:

The only difference in baseline characteristics between the treatment and control groups was the greater frequency of bilateral disease in the CEA group (p=0.009). The CAS procedures were successful in 47 (96.0%) patients; 2 access failures were converted to endarterectomy, and 1 access-site pseudoaneurysm was treated surgically. There were no deaths or myocardial infarctions in either group. In the CAS group, there were no major and only 2 (4.1%) minor strokes compared to 4 (2.9%) major and 4 (2.9%) minor strokes in the CEA group (p>0.05). Median LOS was significantly lower in the CAS group (p<0.0001).

Conclusions:

Careful case selection and multidisciplinary collaboration facilitate the safe performance of carotid stenting in a community setting with acceptable early results.
