For patients with chronic middle cerebral artery occlusions who have recurrent ischemic symptoms despite antiplatelet therapy and vascular risk factor control, treatment options are limited. Because of concerns about the safety of endovascular revascularization of these occlusions and the technical skills required, these procedures have not been widely performed. We report on two patients with successful endovascular revascularization of the chronic middle cerebral artery occlusion with impaired cerebral hemodynamics, with vessel patency maintained on follow-up imaging and no recurrence of stroke. A literature review of treatment options for such patients was performed. Revascularization is technically feasible and can be considered an option for carefully selected chronic middle cerebral artery occlusion patients with recurrent ischemic symptoms despite medical therapy.
