Leadership

Steven L. Gianotta, MD

Nominee Director and Scientific Advisory Board Member

Steven L. Giannotta is a Professor and Chairman of the Department of Neurological Surgery at the University of Southern California Keck School of Medicine in Los Angeles, California. He joined the Department of Neurosurgery at USC in 1980.

His research interests have always been related to cerebral blood flow and cerebral protection from ischemia. Based on some preliminary studies Steven did on how cerebral blood flow could be augmented by various manipulations of the cardiovascular system, his findings and techniques were adapted into the clinical realm as an effective means of counteracting the ischemic effects of cerebral vasospasm. This program ultimately evolved into what has come to be recognized as hyperdynamic therapy.

In addition, his other clinical interests are related to various surgical approaches to intracranial vascular and cranial base neoplastic disease. Recently his attention has turned to looking at ethnic differences in the presentation of cerebral vascular disorders.

Steven has gained recognition for his work in cerebrovascular disease of the brain and spinal cord. He has surgically treated over 1000 intracranial aneurysms. In conjunction with his associates, Steven has developed a comprehensive approach to the gamut of cerebrovascular conditions. Techniques utilized in this comprehensive program include but are not limited to microsurgical clip ligation for aneurysms, coil embolization for aneurysms, microvascular excision, embolization, stereotactic radiosurgery using the Gamma Knife for arteriovenous malformations, carotid endarterectomy and extracranial to intracranial bypass procedures for cerebrovascular occlusive disease.

Steven also has an interest and special expertise in surgical approaches to the cranial base. He has surgically removed more than 400 acoustic neuromas and along with several colleagues in otolaryngology has developed a team approach to complex cranial base lesions including acoustic neuromas, meningiomas of the cranial base, complex aneurysms that require cranial base approaches and other benign conditions affecting the base of the brain and skull. Complex conditions may require several modes of therapy including surgical excision, embolization, and stereotactic radiosurgery using the Gamma Knife and Cyberknife.

Steven grew up in a blue-collar neighborhood in Detroit, Michigan. In high school, he became interested in psychoanalysis, which led him to a medical career and to neurosurgery. He earned his medical degree and did his residency at the University of Michigan.

He is involved in many local, national, and international committees and organizations. Past service includes serving on the Executive Committee (1983-94), being a Secretary (1986-89) and Vice-President (1992-93) of the Congress of Neurological Surgeons; President of the Los Angeles Society for Neurosciences (1991); President (1993-94) and Secretary (1986-93) of the Southern California Neurosurgical Society; Chairman of the Joint Section on Cerebrovascular Surgery of the AANS/CNS (1996-98); President of the Western Neurosurgical Society; Chair (2000-01), Secretary(1999-2000) and Director (1996-01) of the American Board of Neurological Surgery; Chair (2006-08) of the Neurosurgery RRC (2002-08); President of the American Academy of Neurological Surgeons (2009-10); Vice President of the Society of Neurological Surgeons (2010-11); Secretary of the CAST Committee of the SNS (2008-2018).
