Tandem internal carotid artery (ICA) origin occlusion and middle cerebral artery (MCA) thromboembolism is a life-threatening condition with poor neurological outcome. The authors report on a patient presenting with acute ischemic stroke from a tandem ICA and MCA occlusion with penumbra. Emergency MCA mechanical thrombectomy was performed through percutaneous cervical ICA access due to the inability to cross the cervical carotid occlusion. Emergency carotid endarterectomy to reperfuse the poorly collateralized hemisphere and repair the ICA access site was performed 2 hours after completion of tissue plasminogen activator (tPA) infusion. This case illustrates the shortest reported interval between tPA infusion and open surgical intervention for carotid revascularization, as well as the role of direct carotid artery access for mechanical thrombectomy. The authors also describe the use of a temporizing femoral artery–to–ICA shunt to maintain cerebral perfusion in the setting of ICA occlusion.
