Objective
Augmentation index is an important parameter which is used for evaluating arterial stiffness. Arterial stifness is an significant predictor of cardiovascular events. In this study we aimed to evaluate the acute effects of carotis stenting on arterial stifness invasively which calculated by augmentation index and carotid hemodynamic parameters before and after stenting.
Methods
Fifty-one patient who were diagnosed as serebrovascular accident and had stenosis above %70 in internal carotid artery which was shown in non invasive tests were included to our study. During carotis angiography systolic blood pressure, pulse pressure, augmentation pressure before and after stenting were investigated.

Results
The mean age was 70.5±8.6 which range from 48 to 90 years (15 female (35.5%), 36 male (64.5%)). All the patients had been suffered ischemic stroke previously. Heart rate (83,4±15.2 bpm vs. 72,3±8.7 bpm, p<0,01), systolic blood pressure (173.8±35.9 mmHg vs. 127.5±31.4 mmHg, p<0,001), diastolic blood pressure (89.3±18.5 mmHg vs. 74.2±15.1 mmHg, p<0,001), pulse pressure (83.6±31.0 mmHg vs. 52.9±23.0 mmHg, p<0,001), augmentation pressure (20.2±7.9 mmHg vs. 7.1±2.3 mmHg, p<0,001) and augmentation index (24.3±5.8 % vs. 13.9±4.0 %, p<0,001) were significantly decreased after carotid stenting.
