The aim of our retrospective study was to investigate determi-nants for angiographic ISR one year after elective CAS. <Materials and Methods> Included for our analysis were patients 1) who underwent elective CAS for asymptomatic or symptomatic carotid stenosis in our institution from January 2005 to September 2012 , 2) who underwent digital subtraction angiographic (DSA) investigation one year after CAS. Angiographic ISR was defined as a stenosis of more than 50% (NASCET method). We assesed clinical features, oral medications, and radiological findings. <Results> Consecutive 216 patients underwent elective CAS for 249 lesions during the study period. Among them, 217 lesions (87%) were evaluated with one-year DSA. Median follow-up period was 363 days. ISR was detected in 14 lesions (6.5%). Residual stenosis just after CAS was greater in ISR(+) group than ISR(- ) group (median 20 % vs 10 %, p=0.078). Patients took RAS inhibitors more commonly in ISR(+) group than in ISR(-) group (78.5 % vs 53.6 %, p=0.095) and Cilostazol less commonly in ISR(+) group than in ISR(-) group (7.14 % vs 35.6 %, p<0.05). There were no significant differences between ISR(+) group and ISR(-) group in terms of age, sex, commorbidities, other medications, pre-procedure stenosis, stent type. Logistic regression analysis revealed no use of cilostazol was an independent determinant (Odds Ratio 7.37, CI 1.402 - 135.9, p<0.05). <Con-clusion> Cilostazol may reduce one-year angiographic ISR after elective CAS. 16:30-18:00 Rooms 7,8,11,12 Joint Symposium 4 ESC/SIECV
