[Stenting in vertebral artery dissection: an approach to management].
We describe a 56-years-old 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 thread-like 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.
