Tomoyoshi (Tomo) Shigematsu, MD, PhD is as an Assistant Professor of Neurosurgery, Neurology, and Radiology at Mount Sinai Health System dedicated to pediatric and adult cerebrovascular and endovascular neurosurgery. Dr. Shigematsu specializes in the endovascular treatment of pediatric cerebrovascular disorders (including Vein of Galen Malformation, brain and spine arteriovenous malformations/fistulas, and aneurysms), endovascular treatments of craniofacial vascular lesions in adults and children, and the surgical and endovascular treatments of general cerebrovascular diseases (including stroke, intracranial and carotid stenosis, brain aneurysms, arteriovenous malformations and fistulas of the brain and spine, and pre-operative embolization of tumors).

Dr. Shigematsu earned a medical degree from Osaka University Medical School in 2004. He completed full training (residency and fellowship) of neurosurgery and neuroendovascular surgery at Kobe City General Hospital and Osaka University Hospital, both national leaders in cerebrovascular neurosurgery.

He is board certified from the Japan Neurosurgical Society, the Japanese Society for Neuroendovascular Therapy, and the Japan Stroke Society.

Following his clinical interests in pediatric cerebrovascular treatments, Dr. Shigematsu joined the Cerebrovascular Center at Mount Sinai Health System to conduct multiple research programs. While in the United States, he obtained his United States medical licensure and then completed his fellowship in Neuroendovascular Surgery under the tutelage of Alejandro Berenstein, MD.
