BACKGROUND AND PURPOSE: The natural history of the carotid NO is poorly characterized, and the management of patients remains controversial. We report the results and complications associated with CAS and follow-up.
MATERIALS AND METHODS: Between March 2000 and March 2009, 116 of 836 CAS procedures were performed in patients with carotid NO (13.9%). A total of 99 men (85.3%) and 17 women (14.7%) with a mean age of 65.8 years were included. Presenting symptoms were TIA in 44 patients (37.9%) and minor stroke or noninvalidating stroke in 61 (52.6%). One hundred five patients (90.5%) were symptomatic.
RESULTS: A distal filter was used for cerebral protection in 92 patients (79.3%). Transient hemodynamic alterations were frequent during balloon inflation: hypotension (37.1%), bradycardia (48.3%), and asystole in 24.1%. Four patients (3.4%) developed a TIA after CAS. Stroke in progression was arrested in the 1 patient (0.9%). The median follow-up period for patients was 36 months. Asymptomatic restenosis >70% occurred in 5 patients (4.3%); asymptomatic occlusion occurred in 3 patients (2.6%). During follow-up, 3 patients (2.6%) experienced a stroke, 1 ipsilateral (at 19 months) and 2 contralateral (at 6 and 30 months, respectively). Thirteen patients (11.2%) died, 7 from vascular causes.
CONCLUSIONS: Our study showed that carotid NO is an under-recognized condition, and CAS would seem to be beneficial when performed by an experienced neurointerventional team.
