Angioplasty and stenting for mechanical thrombectomy in acute ischemic stroke

A large number of patients presenting with acute ischemic stroke have large artery intracranial occlusions, and timely recanalization of these occlusions often leads to improved neurologic outcome. Starting with the widespread use of IV tissue plasminogen activator, a wide variety of pharmacologic and mechanical methods have been introduced to improve vessel recanalization and clinical outcome of patients with acute ischemic stroke, which include endovascular therapies such as intra-arterial thrombolytics and mechanical thrombectomy devices. One of the potential therapies is angioplasty and stenting, and this has been evaluated in multiple case reports and small series published by various centers regarding its use in this setting. In this article, we review the current literature on stenting with and without angioplasty, used alone or as a part of multimodal therapy for recanalization for acute cerebrovascular occlusions.
