Q&A - Treatment Strategies - Percutaneous

Dr. Yasmine Hoydonckx is an Associate Professor in the Department of Anesthesia and Pain Medicine at the University of Toronto. She has a Master of Science in Clinical Epidemiology. Her interests are in chronic pain treatments, mostly in the area of craniofacial pain. She created the multidisciplinary Intracranial Hypotension program at University Health Network (UHN) in Toronto and the Craniofacial Pain Program at Toronto Academic Pain Medicine Institute.

She has leadership roles in national and international pain organizations such as Canadian Pain Society and American Society of Regional Anesthesia and Pain Medicine. She has received the prestigious 2021 Canadian Pain Society Early Career Investigator Pain Research Grant and more recently the 2024 ASRA Early-Investigator grant for her ongoing randomized controlled KetHead trial where she investigates the therapeutic effect of high dose ketamine infusions on chronic daily headaches. She recently also received PSI funding for an observational study on percutaneous occipital nerve blocks for SIH. Together with Dr. Amoozegar, Dr. Hoydonckx is a co-investigator on a multi-center SIH registry, currently recruiting patients in Calgary and Toronto.

Dr. Hoydonckx is an active member of Medical Advisory Board and the Vice chair of the scientific committee for Spinal CSF Leak Canada.

Dr. Andrew L Callen is Associate Professor of Neuroradiology and Neurology, Neuroradiology, and Director of the CSF Leak Program at the University of Colorado School of Medicine.

Dr. Callen completed his MD at the University of California, San Francisco, School of Medicine in 2014, after earning a BS from the University of California, San Diego, in 2010. Following an internship with Kaiser Permanente in San Francisco (2015), Dr. Callen completed both his residency (2019) and fellowship (2020) in neuroradiology at the University of California, San Francisco.

Dr. Callen specializes in the diagnosis and treatment of cerebrospinal fluid (CSF) leaks, with a focus on both spontaneous and iatrogenic CSF leaks. He has authored numerous scientific manuscripts on CSF leak diagnosis and treatment, and holds a pending patent for a novel patient positioning device for dynamic CT myelography.

Dr. Callen is an active member of the Medical Advisory Board for Spinal CSF Leak Canada and the American Spinal CSF Leak Foundation. He also serves as a Neuroradiology Consultant for the Scientific Committee of Spinal CSF Leak Canada.

Dr. Ian Carroll is Associate Professor of Anesthesiology, Perioperative, and Pain Medicine, Chief, Stanford CSF Leak Headache Program , Stanford University School of Medicine, San Fransisco. In 2015 Dr. Carroll collaborated With Stanford's Neuroradiology and Neurology Headache divisions to create the Stanford CSF Leak Headache Program after his daughter suffered through an initially-undiagnosed CSF leak. This experience left him with a passion for helping patients experiencing CSF leaks around the world. He is board-certified in four different specialties: Headache Medicine by the United Council for Neurologic Subspecialties; Addiction Medicine by the American Board of Addiction Medicine; Pain Medicine by the American Board of Anesthesiology; and Anesthesiology by the American Board of Anesthesiology. His primary focus is on spinal cerebrospinal fluid (CSF) leaks. He has spoken at numerous national meetings on CSF leaks, management of the pain from nerve injuries, and factors influencing opioid cessation. He has conducted visiting professorships at Johns Hopkins University, Vanderbilt University, Yale University, University of California at Davis Medical Center, and others.

Dr. Carroll graduated summa cum laude and Phi Beta Kappa from Columbia University, and then graduated with an M.D. from Columbia University. He was a Research Fellow at the Experimental Immunology Branch at the National Cancer Institute at the National Institutes of Health in Bethesda Maryland. He completed his internship in Internal Medicine, residency in Anesthesiology, fellowship in Pain Medicine, and was elected Chief Resident of Anesthesiology from 2001-2002 at Stanford University Medical Center. He joined Stanford's Department of Anesthesiology as a primary teaching and research faculty in the Pain Management clinic in 2004.

Dr. Carroll completed Stanford's two-year Clinical Research training program earning a M.S. degree in clinical epidemiology from Stanford in 2006. He has published over 50 original articles including research funded by the Foundation for Anesthesia Education and Research (FAER); the National Institute for Drug Abuse (NIDA); and the Stanford Institute for Neuro-Innovation & Translational Neurosciences (SINTN).

In addition to his clinical and research responsibilities, Dr. Carroll helps select and train Stanford Anesthesia residents, Pain Management Fellows and Neurology Headache Fellows.

Dr. Carroll is an active member of the Medical Advisory Board for Spinal CSF Leak Canada and the American Spinal CSF Leak Foundation. He also serves as Consultant for the Scientific Committee of Spinal CSF Leak Canada.

Dr. Howard Meng is an Assistant Professor in the Department of Anesthesiology and Pain Medicine at the University of Toronto and the Director of Pain in the Department of Anesthesiology and Pain Medicine at Sunnybrook Health Sciences Centre. Dr. Meng completed his medical training, including residencies in Anesthesiology and Pain Medicine, at the University of Toronto. His clinical and research interests focus on acute and persistent pain following trauma including peripheral nerve pain and post-traumatic headaches. He leads the Trauma Pain Clinic within the Trauma Recovery Program at Sunnybrook Health Sciences Centre.
