Clinical outcome of patients with acute posterior circulation stroke and bilateral vertebral artery occlusion.
Patients presenting with posterior circulation acute ischemic events are occasionally noted to have occlusion of bilateral vertebral arteries with basilar artery blood flow entirely dependent from the anterior circulation. There is limited data about prognosis of such patients in literature. ⋯ Patients with acute posterior circulation ischemic stroke and bilateral vertebral artery occlusion are at high risk of having early recurrent ischemic events. Reestablishment of the antegrade vertebro-basilar blood flow through endovascular re-canalization might be an option to decrease stroke recurrence in selected patients with acute posterior circulation stroke and bilateral vertebral artery occlusion.
