Small Animal Internal Medicine
The Small Animal Internal Medicine Unit at the AHT has two main purposes. The first is to provide a full clinical referral service in feline and canine internal medicine that complements the other small animal specialties in the clinic. The second is to contribute knowledge and information on important canine and feline diseases, working in conjunction with other veterinarians and scientists at the Animal Health Trust.
We aim to offer a friendly, client-orientated referral service where the needs of the patient come first. We offer a full referral service in canine and feline internal medicine, backed up by extensive clinical and laboratory facilities. We aim to see genuine emergency cases the same day wherever possible.
Our team is composed of five veterinary surgeons and a dedicated veterinary nurse. We work closely with other disciplines at the Trust, utilising the wealth of experience in the specialist services available and hospitalised patients receive complete 24-hour care. We are also able to provide critical care for patients needing intensive monitoring.
Our Specialists in Internal Medicine are available to give telephone advice and in-house consultancy services to veterinary surgeons in both general and referral practices.
The AHT benefits from having a state-of-the-art MRI facility along with all other typical imaging modalities (radiography, ultrasonography and scintigraphy), that permits extensive investigations on site. We also have a full range of endoscopic equipment to allow non-invasive procedures and help with the diagnosis and treatment of various conditions (evaluation of the respiratory, gastro-intestinal and urogenital tract, feeding tube placement, removal of foreign bodies, etc…). We also work in close collaboration with our soft-tissue surgeons if a patient requires a surgical intervention.
The AHT is one of only a very few centres in the UK that is able to offer radioiodine therapy as a treatment for hyperthyroidism, which is a highly successful form of therapy. Cats treated with radioiodine therapy at the AHT only have to remain hospitalised for three weeks.
