Embolization of an Intracranial Vertebral Artery Aneurysm via the Deep Cervical Artery.

Treatment of vertebral artery aneurysms can be challenging due to the unusual vascular anatomy or unfeasibility of traditional endovascular techniques. We describe a novel approach for endovascular treatment of a ruptured intracranial vertebral artery aneurysm with bilateral vertebral artery occlusions and hypoplasia of the posterior communicating arteries. Successful coil embolization was performed using a collateral pathway for microcatheterization via anastomosis between the deep cervical artery and the vertebral artery. This case report highlights a novel alternative endovascular treatment approach for vertebrobasilar aneurysms in case of a poor vascular status with occlusion or lack of traditional endovascular access routes.
