We describe a 56yearsold patient with spontaneous extracranial vertebral artery dissection, which was provoked by neck movements. Clinically dissection manifested with transient ischemic attacks in vertebrobasilar system which lasted during 3 months and often combined with occipital headache. Contrast angiography revealed subtotal stenosis of segment V1 of the right VA, extending from the ostium for a length of 1-1.5 cm with threadlike double lumen (true and false lumens). The rest part of V1 segment of the right VA was irregularly narrowed up to 40-50%. A good contrast filling of the rightVA beginning from segment V2 was carried out by the collateral circulation from thyreocervical trunk. No atherosclerotic plaques in extra intracranial arteries were found. The patient was subjected to stenting of segment VI of right VA that resulted in a complete restoration of the arterial lumen. No postoperative complications were observed.

KEY WORDS: dissection, vertebral artery, transient ischemic attacks, stenting.
