title: Intestinal haemorrhage associated with colonic vascular ectasia (angiodysplasia) in a dog.
abstract: An eight-year-old, sexually intact, male, 37 kg crossbred dog was referred for investigation of two acute episodes of intestinal bleeding and severe anaemia within a five-month period. There was no evidence of coagulopathy or underlying systemic disease. Technetium-labelled red blood cell scintigraphy suggested the colon as the site of bleeding. Colonoscopy identified a focal area of dilated and tortuous mucosal blood vessels. Histopathology of the resected colon revealed vascular ectasia (angiodysplasia). At nine months post-resection, the dog remained healthy and free of any overt intestinal haemorrhage.
