Colin P. Derdeyn MD

Colin P. Derdeyn, M.D. is a professor of radiology, neurology and neurological surgery and director of the Stroke and Cerebrovascular Center at Washington University. He received his B.A. (Echols Scholar) from the University of Virginia in 1984, and his M.D. from the University of Virginia in 1988. After a year as an intern in general surgery and a year as a resident in neurological surgery at the University of North Carolina, Chapel Hill, he became interested in the developing field of interventional neuroradiology. He completed a radiology residency at the Mallinckrodt Institute of Radiology, Washington University School of Medicine, in 1994, where he served as chief resident his final year. This was followed by a year as a stroke fellow at Washington University. His final year of clinical training (1996) was spent gaining dedicated experience in neuro-endovascular techniques at the University of Wisconsin-Madison as a fellow in interventional neuroradiology. He joined the staff at Washington University in 1996. He is currently the program director for the ACGME-approved Endovascular Surgical Neuroradiology Training Program.

Dr. Derdeyn is a past president of the Society for NeuroInterventional Surgery, the national medical society for endovascular neurointervention. He is on the editorial board of Stroke and the American Journal of Neuroradiology. He has been active in the national committees of the American Heart Association, including the National Research Committee, the Stroke Council Leadership Committee, and he is a past chair of the Stroke Council Scientific Statement Oversight Committee. He chairs the NIH Data Safety and Monitoring Board for two randomized clinical trials of acute stroke intervention.

Dr. Derdeyn’s practice is limited to the endovascular treatment of cerebrovascular disease, including brain aneurysms, atherosclerotic stenosis, arteriovenous malformations and ischemic stroke. His research is similarly focused on these areas. He is the director of a large, NIH-funded, stroke research center (Specialized Programs for Translational Research in Acute Stroke (SPOTRIAS). He holds an RO1 for the investigation of the mechanism of stroke in patients with moyamoya disease, an unusual condition leading to the narrowing and occlusion of large brain arteries that typically affects young adult women. He is an executive investigator (interventional co-PI) for a multi-center randomized trial of angioplasty and stenting versus medical therapy for intracranial atherosclerotic disease (SAMMPRIS).
