Plain-English summary
An eight-year-old male crossbred dog weighing 37 kg was taken to the vet because he had two sudden episodes of bleeding in his intestines and was very anemic over the past five months. Tests showed that he didn't have any blood clotting issues or other serious health problems. A special scan indicated that the bleeding was coming from the colon, and a procedure called colonoscopy found a specific area with swollen and twisted blood vessels. After the affected part of the colon was surgically removed, a tissue examination confirmed the diagnosis of vascular ectasia (angiodysplasia), which is an abnormality of blood vessels. Nine months later, the dog was doing well and had not experienced any further intestinal bleeding.
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.
