Vertebrobasilar insufficiency secondary to vertebral artery occlusion from a fibrous band

Case report

Restricted access

✓ A case is described in which vertebral artery occlusion, caused by a fibrous band, occurred whenever the patient turned his head to the right side, resulting in vertigo and syncope whenever the head was turned to the right. Release of a fibrous band crossing the vertebral artery 2 cm from its origin relieved the patient's vertebral artery constriction and symptoms.

    Preoperative angiograms (upper) and diagrams (lower) of the patient. Left: The patient's head is in a neutral position. The vertebral artery is patent. Right: The patient's head is turned to the right. The vertebral artery is completely occluded (arrow). The patient became lightheaded and vertiginous.
