Joseph S. Megyesi, MD
Professor of Neurosurgery, Western University
Office: London Health Sciences Centre, University Hospital B10-007
Secretary: Karen Hailstone
Dr. Megyesi received his MD from Western University in 1985. He completed a comprehensive surgical internship the same institution followed by a neurosurgical residency at the University of Alberta Hospitals in Edmonton. Following his training, Dr. Megyesi completed fellowships at Harvard University and the University of Alberta.
Dr. Megyesi joined the Department in 1998 and specializes in neuro-oncology. He is currently Assistant Professor in the Division of Neurosurgery at Western University. He is also Director of Research in the Division of Neurosurgery, coordinator of Neurosurgery Residency Seminar Series and Board Member of Brain Tumor Tissue Bank.
Dr. Megyesi's clinical research interests focus on angiogenesis in brain tumors. A tumor's ability to grow is linked to its ability to recruit a supply of new blood vessels. In order to do this, it sends out "signals" to already existing blood vessels to sprout new branches to feed it. This is the process of angiogenesis. His past studies have investigated angiogenic growth factors such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).
Dr. Megyesi's research interests also include cerebral vasospasm in the brain. Cerebral vasospasm is delayed-onset, prolonged and pathological cerebral arterial narrowing following aneurysmal subarachnoid hemorrhage (SAH). His past work has looked at the treatment of this disorder using transluminal balloon angioplasty in an animal model.
