Manuel Fortes, M.D.
Dr. Fortes is a native of Rio de Janeiro, Brazil. He went into medical school and successfully pursued his medical doctorate at his native city, graduating in 2004. After a year of internal medicine internship, he completed a Diagnostic Radiology residency at the prestigious Federal University of Sao Paulo program. He was than accepted into an extremely competitive Interventional Radiology fellowship program at the Medical University of South Carolina where he specialized in the management of arterial and vascular disease processes. In order to obtain expertise in the complex vascular disease processes of the brain, Dr. Fortes received extensive additional training in a 3 years combined Neuroradiology/Endovascular Surgical Neuroradiology fellowship program. This took place at the University of Maryland Medical Center, Shock Trauma. UMMC Shock trauma is consistently ranked one of the 2 busiest trauma centers in the country, with extensive exposure to vascular diseases of the brain in the acutely ill. In 2013 after completion of extensive clinical training, Dr. Fortes became a fully board-certified physician and a Diplomate of the American Board of Radiology. Dr. Fortes has been a credentialed Interventional Neuroradiologist at Integris Baptist Medical Center and affiliated hospitals since July, 2013. His areas of interest include: brain aneurysms, acute stroke, carotid stenosis and stenting, arterial venous malformations and dural arterio-venous fistulas of the brain and spine. He also performs spine care including kyphoplasties, spine tumors ablation and epidural injections to treat chronic back pain. On daily practice he utilizes the latest equipment including artificial intelligence for the early detection of acute stroke and always based on the most current literature. Dr. Fortes is a senior member of the Society of Neurointerventional Surgery (SNIS) and the Society of Interventional Radiology (SIR). His editorial responsibilities include an active role as a reviewer for the Journal of Neurointerventional Surgery (JNIS), the leading publication in the field.
