Value of Other Endovascular Techniques Among Patients with MERCI Device Failure during the Treatment of Acute Ischemic Stroke

摘要

Background:The MERCI Retrieval system (Concentric Medical, Mountain View, CA) was the first FDA-approved device for mechanical thrombectomy in patients with acute ischemic stroke. It remains one of the most commonly used devices today despite its failure to restore blood flow in approximately 50% of the occlusions after technically successful deployment and retrieval. It remains unclear whether additional endovascular techniques or continued use of MERCI device can achieve recanalization post-MERCI failure.
