Introduction. A prospective, randomized and controlled trial is conducted to compare carotid endarterectomy and carotid stenting in high grade symptomatic carotid artery stenoses. Methods. According to the study design symptomatic patients with a angiographically highgrade (greater than or equal to 70%) internal carotid artery stenosis are included. Pre- and postinterventional diagnostics during the hospitalization period includes neurological assessment, duplex sonography of the cervical and cerebral arteries and magnetic resonance imaging of the brain. Follow-up examinations are scheduled after 1,6 and 12 months and consist of a neurological assessment and duplex sonography. After 12 months selective angiography and magnetic resonance imaging of the brain will be performed additionally. During a period of 9 months up to now 23/137 patients treated for a carotid artery stenosis were included in the study,ll patients underwent surgery and 12 patients carotid stenting. Results. Carotid stenting and endarterectomy was primarily successful without residual stenosis >30% in each patient without the occurence of stroke or death. In 18 follow-up examinations (neurological assessment including duplex sonography) of 13 patients (13 follow-up examinations after 30 days, 5 after 6 months) no relevant restenosis and no stroke occured. Conclusion. As of yet, carotid stenting was a safe procedure. Due to the small number of patients a definitive conclusion can not be drawn.
