Abstract

A 2-year-old spayed female crossbred dog was presented for profuse, acute, and chronic vaginal hemorrhage. Coagulation disorders were excluded. Conventional diagnostic imaging failed to precisely identify the source of bleeding. After whole-blood transfusion, magnifying endoscopy with narrow-band imaging allowed the visualization of unique vascular patterns within the vaginal wall. Presumptive diagnosis of vaginal vascular ectasia was made and confirmed by histopathological examination. Surgical management with subtotal vaginectomy cured the dog. Key clinical message: Vascular ectasia is rarely reported in veterinary medicine and is challenging to diagnose. This is apparently the first report of the usefulness of magnifying endoscopy with narrow-band imaging as a diagnostic tool for vascular ectasia in a dog.
