Angiodisplasia de cólon em um cão

Abstract

The angiodysplasia of the colon is an alteration characterized by the presence of vascular abnormalities on the intestinal mucosa. It is a rare condition in dogs, with it’s pathogenesis yet to be fully understood. The diagnosis is made by visualizing an abnormal pattern of the colonic mucosa vascularization, through colonoscopy. The treatment options include argon plasma coagulation, surgical resection of the affected portions of the colon, and medical management. The purpose of the present study is to report the case of a 13 year-old neutered male dog, presenting with intermittent hematochezia for 3 years, diagnosed with colonic angiodysplasia through colonoscopy. After starting hormonal therapy with Estriol, the hematochezia was controlled, and no side effects of the treatment were observed during the time the patient was monitored.
