Abstract :
[en] 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. [fr] Apport de la fonction imagerie à bande étroite en endoscopie pour la détection d’une ectasie vasculaire primaire chez un chien. Une chienne femelle stérilisée de race croisée a été présentée pour récidive aiguë et profuse de saignements vaginaux perdurant de façon intermittente depuis l’adoption. Le bilan de coagulation ne présentait pas d’anomalie et les examens d’imagerie conventionnels n’ont pas permis d’identifier avec certitude l’origine de l’hémorragie. Après transfusion, la réalisation d’une endoscopie utilisant un processus informatique de chromoscopie virtuelle par bandes spectrales étroites a permis la visualisation d’un réseau vasculaire anormal sur la paroi vaginale. La présomption d’ectasie vasculaire vaginal a été confirmée par examen histologique. La résolution complète des saignements a été constatée après réalisation d’une vaginectomie subtotale.Message clinique clé:Les ectasies vasculaires (angiodysplasie) sont peu souvent rapportées en médecine vétérinaire et leur diagnostic est difficile à établir. Ce cas relate pour la première fois l’intérêt de la chromoscopie virtuelle par bandes spectrales étroites en endoscopie vétérinaire dans la prise en charge diagnostique d’une ectasie vasculaire vaginale chez un chien.(Traduit par les auteurs).
