Since moving to Maryland, Dr. McDonnell has become well-known for his work in the definitive treatment of brain tumors and spinal cord tumors, foramen magnum decompression/dorsal laminectomies and Wobbler's disease. He has lectured nationally, internationally and regionally, and has published more than 20 journal articles, reviews and book chapters.
"Teaching continues to be important to me. I'm an assistant clinical professor at Tufts University and a consultant in Neurology at the University of Pennsylvania College of Veterinary Medicine. I think having a balance of the academia and private practice enables me to keep at the forefront of veterinary neurology."
Most recently, Dr. McDonnell has been exploring the use of pituitary surgery to treat Canine Cushing's Disease here in the U.S.
"Surgery for pituitary macroadenomas in dogs and cats has been pioneered by Dr. Bjorn Meij of the University of Utrecht in the Netherlands. Despite his work and the proven success of the technique over other treatments such as radiation and chemotherapy, the surgery has failed to be widely adopted here as a viable treatment option. The procedure is technically challenging and has a very steep learning curve, so I went to the Netherlands in the spring of 2010 to study with Dr. Meij;and I also arranged a special seminar with Dr. Meij at the University of Pennsylvania College of Veterinary Medicine. Currently no one east of the Mississippi is offering this treatment option, so it's exciting to be able to offer this."
There are thousands of cases of Canine Cushing's Disease in the U.S. each year, but the current medical treatment is medication given daily or several times per week that treats the symptoms. "With this surgery, we finally have a treatment option that corrects the disease."
