Overview

Steven L. Giannotta M.D., Chair of Neurological Surgery, 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 done in primates early in his career it was discovered that cerebral blood flow could be augmented by various manipulations of the cardiovascular system. This resulted in the adaptation of such techniques in the clinical realm especially 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". Subsequently his clinical interests have 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.

Dr. Giannotta 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 Dr. Giannotta 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.

Dr. Giannotta 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.

Dr. Giannotta earned his medical degree and did his residency at University of Michigan.

He is involved in many local, national and international committees and organizations.
