Mechanical Thrombectomy of Acute Middle Cerebral Artery Occlusion Using Trans-Anterior Communicating Artery Approach

Timely recanalization of an occluded artery plays a critical role in the prognosis of patients with acute ischemic stroke. Successful stent retriever mechanical thrombectomy of an occluded MCA is possible using a transanterior communicating artery approach in patients without a direct access route to the occluded intracranial vessel. We review the pathophysiology of tandem lesions, access routes to intracranial occlusions, and the literature on cross-circulation techniques to treat emergent large-vessel occlusions.
