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.
