Mechanical Thrombectomy via the Transfemoral Approach for Acute Middle Cerebral Artery M1 Occlusion That Occurred during Intra-Aortic Balloon Pumping Application.

Objective: We report a case of cardioembolic stroke treated by mechanical thrombectomy (MT) via the transfemoral approach under the assistance of intra-aortic balloon pumping (IABP).

Case Presentation: A 64-year-old man suddenly developed consciousness disturbance, aphasia, and left hemiparesis during intensive care for acute myocardial infarction (AMI) with IABP. The patient was transferred to our hospital and diagnosed with acute right middle cerebral artery (MCA) occlusion. We performed MT using a balloon-guiding catheter via the transfemoral approach and achieved complete recanalization.

Conclusion: Endovascular therapy for acute MCA M1 occlusion via the transfemoral route was safe even when the patient was treated using IABP.
