Background Timely recognition of stroke at major pediatric medical centers is improving, and although treatment guidelines for pediatric stroke exist, no extensive study establishing the efficacy of surgical or thrombolytic treatment has been completed. Extrapolation of adult guidelines to pediatric patients remains the mainstay of treatment in the absence of adequate information regarding safety and efficacy in children. Recent trials have demonstrated revascularization and clinical improvement after endovascular retrieval therapy in adults with acute large vessel occlusive stroke. Furthermore, successful mechanical thrombectomy using a variety of techniques has been documented in numerous children and adolescents. Patient Description We present a 15-year-old boy with altered mental status and left hemiparesis due to acute ischemic stroke secondary to blockage of the right internal carotid artery terminus, most likely precipitated by end-stage heart failure and cardiac embolism. Mechanical aspiration thrombectomy using the Penumbra aspiration catheter without any adjunct surgical equipment or thrombolytic therapy was used to remove thrombus and treat the patient's acute ischemic stroke. He experienced complete artery recanalization with a Thrombolysis in Cerebral Infarction (TICI) score of 2C after the procedure. He also exhibited an 8 point improvement in his pediatric National Institutes of Health Stroke Scale score within 24 hours. Conclusions Mechanical aspiration thrombectomy is commonly used in adult hospitals but infrequently employed in pediatric patients with arterial ischemic stroke. Given its efficacy in our patient, we encourage a larger systematic trial to evaluate the use of mechanical thrombectomy in pediatric patients with acute ischemic stroke.
