Title

Endovascular Treatment of Tandem Common Carotid Artery Origin and Distal Intracranial Occlusion in Acute Ischemic Stroke

Abstract

BACKGROUND: Tandem occlusion resulting in acute ischemic stroke is associated with high morbidity and mortality and a poor response to thrombolytic therapy. The use of endovascular strategies for tandem stroke cases results in an improved outcome for this subgroup of patients. We present 2 cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques. METHODS: The 2 patients presented each with occlusion at the left CCA origin and ipsilateral intracranial vessel (left middle cerebral artery and carotid terminus, respectively). A transfemoral anterograde approach was used to deliver a balloon-mounted stent across the proximal CCA origin occlusion to gain access to the distal cerebral vasculature. Subsequently, a stent retriever assisted mechanical aspiration thrombectomy was used to revascularize the intracranial occlusion. RESULTS: Complete revascularization with Thrombolysis in Cerebral Infarction scores of 2b and improvement in neurologic deficits occurred in both cases. Good clinical outcome was achieved for both patients at 3-month follow-up. CONCLUSIONS: An anterograde transfemoral approach should be considered in cases of tandem occlusion of the proximal CCA and middle cerebral artery.
