Abstract

Purpose: To report the experience of carotid artery angioplasty with stenting (CAS) by cardiologists (CV) and neuroradiologists (NR.) in an area with less incidence of extracranial artery stenosis. Methods: From 1999 to 2008,210 patients with 231 stents were collected by claim records from the administrative office and reviewed by one independent neurologist. Outcome measures were peri-procedural adverse events (AE), restenosis and recurrent ipsilateral stroke (RS) rate, categorized into treatment groups by either CV or NR. Results: The average age was 69.0 years and 82.9 % of the patients were men. 63.8% of the patients with 62.8% stents were treated by CV and the remaining 36.2% of patients with 37.2% stents were done by NR. Symptomatic CAS was evident in 70.1% of the CV cases and 83.0% in NR treated patients (P = 0.017). The peri-procedural AE rate was 31.6%; 35.9% in CV group and 24.4% in the NR group (P = 0.071). RS rate was 4.8% in 663.3 days; 4.1% in 920.8 days in the CV group and 5.8% in 354.2 days in the NR group (P = 0.865). The restenosis rate was 10.9% in 630.5 days; 5.4% in the CV group in 224.8 days and 20.6% in the NR group in 817.8 days (P = 0.007). Conclusions: The restenosis and recurrent stroke rates after carotid artery stenting in Taiwan appears to be consistent with other published and well organized trials. Measures to minimize peri-procedural AR rates are definitely warranted.
