Abstract

Bow Hunter's syndrome (BHS), also known as rotational vertebral artery occlusion (VAO), is a rare entity in which vertebral artery is reversibly compressed due to rotation or extension of the head, causing vertebrobasilar insufficiency. Because of VAO, BHS should be considered as a possible life-threatening condition. Diverse aetiologies of BHS may trigger a broad spectrum of non-specific symptoms and may result in frequent misdiagnosis of this disorder in daily clinical practice. Herein, we present a case of BHS caused by previously non-described vascular aetiology.

Keywords: Bow Hunter’s syndrome; rotational vertebral artery occlusion; vertebral artery coiling.
