“…CVE is rare in dogs, with only seven cases described before the present report (Table 1). 1,2,[4][5][6]8 This is the first case report of successful treatment of acute life-threatening (HCT 4.9%) CVE with oral ethinyl estradiol and norethindrone acetate in a dog. While acute CVE cases have already been reported with successful use of blood transfusion and hormone therapy, the severity of anaemia at presentation in this case was greater than in previous reports (the lowest reported HCT being 12.5%).…”

A 7‐year‐old, neutered, male miniature pinscher was presented with a 36‐hour history of acute life‐threatening haematochezia and severe anaemia (haematocrit 4.9%). A diagnosis of acquired colonic vascular ectasia was ultimately made from the characteristic gross morphologic vascular abnormalities visualised during colonoscopy. A combination ethinyl estradiol and norethindrone acetate tablet was prescribed. On recheck 6 weeks after starting hormone therapy, the patient had not had haematochezia for the previous 4 weeks (haematocrit 34%). On the recheck visit 12 months after starting hormone therapy, haematocrit was within reference range (50%) and the patient had not had diarrhoea or haematochezia for the preceding 9 months. This is the first case report describing a successful medical management of an acute haemorrhagic crisis related to acquired colonic vascular ectasia without endoscopic‐assisted argon therapy or colectomy.

“…This disorder cannot be identified by exploratory laparotomy. Sub‐total colectomy is a possible treatment option, especially where significant haemorrhage has occurred (Charlesworth and others 2013). Novel treatment options, such as laser‐ or endoscopic‐assisted argon coagulation (Harris and others 2016) and hormonal therapy with a combination of oral oestrogen and progesterone (Goldman and others 2008), have been reported.…”

Haematochezia is defined as the passing of fresh blood in the stools, and is a commonly encountered problem in dogs and, more rarely, in cats seen in first-opinion veterinary practice. This clinical sign causes anxiety to owners and can also indicate a more severe underlying disease, although this is often benign. Thorough history taking is key to narrowing down an extensive list of differential diagnoses; this should include dietary exposure and a thorough clinical examination, including digital rectal examination. This article gives guidelines on the approach to haematochezia as well as on the diagnosis and treatment of the most commonly encountered conditions for which it is a clinical sign.

“…It can be caused by various etiologies, such as coagulation disorders, neoplasia, toxin exposure, non-steroidal anti-inflammatory drug (NSAID) administration, hepatic or renal disease, hypoadrenocorticism, and vascular anomalies ( 1 ). Vascular anomalies are rarely reported as a cause of GI hemorrhage in dogs, with only a few case reports describing vascular ectasias in the colon ( 2 , 3 ), cecum ( 4 ), and small intestine, such as jejunum ( 5 , 6 ), and are summarized in Table 1 . Vascular anomalies are more frequently diagnosed as a cause of GI bleeding in humans.…”

Case report: The first description of a Dieulafoy's lesion in the gastric mucosa of a dog

et al. 2022

An approximately 12-year-old, 31 kg, male neutered Labrador Retriever was presented to the referring hospital with an acute onset (less than 1 day) of hematemesis and melena. The dog was treated supportively for a presumptive gastric ulcer for 4 days with intravenous fluids, gastro protectants, such as pantoprazole, misoprostol, sucralfate, and barium, as well as an anti-emetic (maropitant) and analgesics (fentanyl, gabapentin, and tramadol). Throughout medical management, the dog continued to require blood transfusions approximately every 24 h. Given the poor medical response, the patient was subjected to an exploratory laparotomy. During surgery, a grossly raised, blister-like lesion on the mucosal surface of the stomach was appreciated on the lesser curvature of the stomach. A partial gastrectomy was performed, and the segment was submitted for histological evaluation. Histologically, there were multiple, tortuous, medium-caliber muscular arteries (>1.0 mm in diameter) in the submucosa. A single large-caliber artery (>0.75 mm in diameter) containing a partially occlusive thrombus extruded through the mucosa and projected on the ulcerated surface. The patient's signs were similar clinically and histopathologically to Dieulafoy's lesion in people. A Dieulafoy's lesion is a potentially life-threatening disorder that causes gastrointestinal (GI) hemorrhage. This lesion is characterized by a dilated, large-caliber, aberrant submucosal artery that erodes through the epithelium and ruptures, resulting in massive and potentially fatal hemorrhage. This lesion has never been documented previously in a dog.
