ZEISS QEVO Path

Early user experience with a novel visualization tool in neurosurgical procedures

Three leading neurosurgeons, Dr. Cohen, Dr. Sivakumar and Dr. Gardner will provide an overview of their experiences as early adopters on the use of QEVO® from ZEISS, the Micro-Inspection tool, along with a surgical microscope in neurosurgical procedures, their personal reflections and learning curve, using case examples.

Date & Time:

Tuesday, April 28, 2020 | 11:00 AM – 12:00 PM (PDT) / 2:00 PM – 3:00 PM (EDT)


About the Speakers:

Aaron Cohen-Gadol, MD, MSc, MBA, is a neurosurgeon at Indiana University Department of Neurosurgery. He is the founder and president of The Neurosurgical Atlas. His clinical research interests include neurosurgical operative anatomy, innovative operative approaches to deep lesions, and intraoperative fluorescence/mass spectroscopy. His basic science research is focused on novel drug therapies for glioblastoma.

Walavan Sivakumar

Walavan Sivakumar is a fellowship-trained neurosurgeon with a focus on skull base and minimally invasive and endoscopic neurosurgery. Dr. Sivakumar has a particular interest and expertise in brain tumors, skull base tumors, pituitary/parasellar tumors, and intraventricular brain tumors, and he applies the keyhole concept, utilizing advanced neuroimaging and microsurgical techniques to minimize collateral damage to the brain. He serves as the Director of Neurovascular Surgery at the Pacific Neuroscience Institute and Director of Neurosurgery at Providence Little Company of Mary Medical Center. Dr. Sivakumar has over 50 peer-reviewed publications, largely focused on brain tumor biology and skull base surgery outcomes.

Award highlights include the William H. Sweet Award from the American Association of Neurological Surgeons (AANS), Stryker Neuro-Oncology Award from the Congress of Neurological Surgeons (CNS), and best research awards from the Rocky Mountain Neurosurgical Society (RMNS) and Western Neurosurgical Society (WNS). He completed his residency training in Salt Lake City at the University of Utah, and his fellowship in Endoscopic Skull Base and Pituitary Surgery and Minimally Invasive Neurosurgery with Dr. Daniel Kelly at the John Wayne Cancer Institute.

Dr. Sivakumar is an active member of the AANS and CNS, currently serving as the secretary on the AANS Young Neurosurgeons Committee and executive committee of the AANS/CNS Section on Tumors. He has a deep interest in neurosurgical trainee education and is involved in the Clinical/Research Neurosurgical Fellowship at the John Wayne Cancer Institute.
