The aim of this study was to determine the incidence of vascular events during a 7-year follow- up evaluation in a group of 34 hypertensive patients with kinking of the internal carotid artery and 36 well-matched hypertensive control subjects. The carotid intima-media thickness (IMT) was measured at three points of the carotid bifurcation and at three points of carotid kinking on the ultrasonographic posterior wall. The mean IMT measured in the segment of the angular bending was lower than the mean values detected at the bifurcation in normal subjects and in hypertensives without carotid elongation (p<0.01). At the carotid bifurcation of the same side of the kinking, there was an arterial IMT that was significantly lower as compared to the contralateral axis and to the measurements obtained in other hypertensive subjects. During a 7-year follow-up study, 10 vascular events occurred in the hypertensives with carotid kinking and 14 in the controls, without significant differences between the 2 groups. In hypertensives with carotid kinking, the mean IMT measured on the angular bending and at the ipsilateral carotid bifurcation was significantly lower than the values obtained at the contralateral bifur cation and in the other hypertensive subjects. In the 7-year follow-up study, moreover, the presence of carotid kinking does not impact the incidence of vascular events in the hyperten sive population. Thus, the presence of carotid kinking in hypertensive subjects may not be considered a further risk factor for ischemic events.
