Bio
Biography
Dr. Alexander Coon serves as the director of Endovascular Neurosurgery for The Johns Hopkins Hospital. His practice focuses on the surgical and endovascular treatment of aneurysms, arteriovenous malformations (AVMs), cavernous malformations, and dural arteriovenous fistulas (dAVFs) of the brain and spinal cord. Dr. Coon utilizes the latest surgical and endovascular techniques to treat patients with carotid artery stenosis, acute stroke, intracerberal hemorrhage (ICH), subarachnoid hemorrhage (SAH), and moyamoya disease. He also focuses on the specialized treatment of epilepsy, spinal disorders, neurological trauma, and hydrocephalus.
Additionally, Dr. Coon has expertise in the pre-operative embolization of tumors of the brain and spine. He works closely with members of the division of neurosurgical oncology and spine to decrease blood flow to solid tumors before surgical resection.
Dr. Alexander Coon currently sees patients at the Johns Hopkins Hospital Outpatient Center (JHOC) on Mondays or by alternate appointment in his office.
