Veterinary IR

Dr. Thomson begins by taking us through his training. During his residency at the University of Minnesota, Shamar Young taught him embolizations and interventional oncology at the medical school and the veterinary school there. He then adapted it to dogs. He then did a surgical oncology fellowship at Colorado State which grew his passion for practicing interventional oncology. There is no training specifically for IR; you train in your specialty of cardiology or oncology, then go on to learn IR skills later in practice.

In the interventional oncology world, Dr. Thomson does prostate artery embolizations for prostate tumors, chemoembolizations, and caval and urethral stents for malignant obstructions. He primarily treats cats and dogs, but occasionally he will help out with an intervention for an animal at the San Diego Zoo. He recently helped do renal sclerotherapy for a dik-dik to treat idiopathic renal hematuria. Dr. Thomson discusses some of the challenges he faces with the different sizes of animals he treats. The size of the animal and the size of the equipment often don’t match up well which poses many technical difficulties for the operator.

We end by discussing the future of veterinary IR. In the cardiovascular IR world, veterinary specialists are beginning to do endovascular valve replacements. In the interventional oncology world, radiofrequency ablation and cementoplasty for appendicular bone tumors is the next big procedure that will impact many patients. Dr. Thomson is excited about being able to provide this minimally invasive treatment for his cat and dog patients as it will prevent many amputations and allow his patients to receive chemotherapy while retaining the highest quality of life possible.
