The Pituitary Surgery Service at the WSU Veterinary Teaching Hospital is committed to providing the very best surgical care for your dog or cat.

Our Services

pituitary surgeryWSU is currently the only veterinary hospital in the country performing transsphenoidal hypophysectomy, a surgery used in the treatment of pituitary tumors and other masses near the pituitary gland. The most common pituitary tumor in dogs is a functional pituitary mass that causes Cushing’s disease. For cats, the most common pituitary tumor is a functional mass that causes acromegaly, where the pituitary produces too much growth hormone. Dr. Owen has performed transsphenoidal hypophysectomy surgeries on nearly 60 animals over the last five years. She was the first veterinarian in the United States to perform this surgery, initially at VCA West Los Angeles Animal Hospital under the guidance of Adam Mamelak, MD from Cedars Sinai Medical Center, a renowned neurosurgeon and expert on transsphenoidal hypophysectomy.

Our Surgical Team

Our board certified team, led by pituitary surgical specialist Dr. Tina Owen, includes neurologist Dr. Annie Chen-Allen and critical care specialist Dr. Linda Martin.  The team also includes neurology residents and veterinary technicians specializing in surgery, neurology, anesthesia and critical care. We work collaboratively with board certified veterinarians specializing in internal medicine, radiology, and anesthesia to be able to offer our patients the best treatment options.

    I’ve waited a full year before writing about my experience with Otto's pituitary tumor because upon reflection I get so emotional I can't keep going. It’s time I wrote his story. Otto is a 3 legged big beautiful black cat with so much personality that when trucks pull up to the house he will climb in the back, when I have friends or family over Otto takes a chair that has been pulled up and watches the group.

    WSU’s Pituitary Team: Leading the Nation in Pituitary Surgical Treatment
    Anna, a 10-year-old chestnut colored boxer with dark brown ears and a white patch on her chest, had always been a healthy and active dog. But in the spring of 2014, her owner, Sundays Hunt of Salt Lake City, Utah, noticed Anna grew lethargic and was less interested in playing with the other two dogs. She was also eating all the time. “I couldn’t feed her enough,” says Hunt. “It was never enough.”
