후경부 감압술로 치료한 회전성 추골동맥증후군 1예

Abstract

Rotational vertebral artery syndrome (RVAS) is a rare disease entity. RVAS is characterized by recurrent attacks of vertigo, nystagmus, ataxia, and tinnitus, which is elicited by head-rotation when the contralateral dominant vertebral artery is compressed, leading to an acute reduction of blood flow in the vertebrobasilar territory. A 50-year-old female presented with a whirling type vertigo which, when turning her head to the left, compressed the dominant right vertebral artery, as documented by the dynamic neck angiography. The patient underwent posterior cervical decompression of the foramina transversaria and the surrounding soft tissues at the level of C1-C2. The patients’s symptom disappeared after the surgery and she has been followed up for the last four months without the recurrence of vertigo.
