Endovascular Mechanical Thrombectomy for Ischemic Stroke Treatment in the Setting of Aortic Dissection: Case Report.

Introduction: Acute ischemic stroke can occur in the setting of aortic dissection. Information concerning the utility of endovascular mechanical thrombectomy as an intervention for patients with aortic dissection who are experiencing an acute stroke due to large vessel occlusion is limited to a few case reports. Case series of patients presenting with this clinical situation are needed to further investigate the potential utility of this procedure when patients with acute ischemic stroke and aortic dissection are encountered. Case Presentation: We report a patient with a chronic Stanford type A aortic dissection with dissection extension into the left common carotid artery and left internal carotid artery who had a good clinical outcome following mechanical thrombectomy for a symptomatic middle cerebral artery occlusion. We also review other cases in which endovascular mechanical thrombectomy was conducted in patients with aortic dissection and acute ischemic stroke and discuss the potential risks and benefits of carotid artery stenting in this clinical situation. Conclusion: The rate of successful arterial recanalization in patients with aortic dissection, large vessel occlusion, and acute ischemic stroke treated with mechanical thrombectomy is high. The intervention has been associated with good neurological outcomes and a low rate of procedure-related complications. Additional case series are needed to help discern if our observations are present in a broader array of patients in order to identify which patients are most likely to benefit from mechanical thrombectomy.
