Dr. Fifi is a board-certified neuroendovascular surgeon and an Associate Professor of Neurology, Neurosurgery, and Radiology. She is also Associate Director of the Cerebrovascular Center and Director of the Endovascular Stroke Program at the Mount Sinai Health System. Dr. Fifi specializes in the endovascular treatment of cerebrovascular disorders including stroke, intracranial and carotid stenosis, brain aneurysms, arteriovenous malformations and fistulas of the brain and spine, and pre-operative embolization of tumors, as well as craniofacial vascular lesions in adults and children.
Born in the Republic of Trinidad & Tobago, Dr. Fifi earned a combined biomedical engineering and medical degree from the Boston University School of Medicine. She performed her medicine internship and neurology residency at Thomas Jefferson University Hospital. Dr. Fifi completed a clinical fellowship in stroke and cerebrovascular disorders at the National Institutes of Health (NIH) in Bethesda, Maryland. While at the NIH, she was co-investigator of several phase II and phase III clinical trials for treatment of acute ischemic stroke. Dr. Fifi then trained in Interventional Neuroradiology at Washington Hospital Center and at Columbia University. After her neurointerventional training, Dr. Fifi completed further studies in pediatric neurointervention under the tutelage of Alejandro Berenstein, MD at Mount Sinai West. During this period, she was invited to join the neuroendovascular group as a staff physician where she has developed a clinical practice taking care of patients with vascular disorders of the brain, spine, head and neck. Dr. Fifi continues her clinical research as an investigator in several multi-center trials.
Dr. Fifi has published her research in peer-reviewed journals and has presented her work at national and international meetings, including the International Stroke Conference. She is a member of the American Stroke Association, Society for Vascular and Interventional Neurology (SVIN), and Society of NeuroInterventional Surgery. She is currently a member of the national board of the SVIN. She is an elected fellow of both the American Heart Association and the SVIN.
