Congenital subcutaneous arteriovenous malformation in a puppy: diagnosis with CT angiography

Abstract

A 4-month-old, 20 kg, intact male, cane corso dog was presented with a slowly growing subcutaneous lesion on the left caudoventral abdominal wall. Ultrasound and computed tomography angiography revealed a subcutaneous plexus of aberrant tortuous vessels directly connected with the superficial branch of the deep circumflex iliac artery and vein. The arteriovenous malformation (AVM) was successfully surgically removed. Early recognition and surgical removal of AVM can have excellent cosmetic results and prevents potential cardiovascular complications.

“…7 Congenital hepatic AV malformations are the most commonly reported AV malformations in the veterinary literature, but acquired cases secondary to trauma (surgical and other forms), and neoplasia have also been reported. 2,8,17,[9][10][11][12][13][14][15][16] Treatments reported to date include ligation of the feeding vessel, embolization of the feeding vessel with liquid, glue or a coil, or surgical resection with or without prior embolisation. 2,[8][9][10][11][12][13][14][15][16][17] Embolization was discussed as a treatment option for this case as it has been successfully performed in veterinary species for treatment of AV malformations.…”

“…1,2 Several cases of Arteriovenous (AV) malformations and AV fistulae have been described in the veterinary literature. 2,[8][9][10][11][12][13][14][15][16][17] Treatments reported to date include ligation of the feeding vessel, embolization of the feeding vessel with liquid, glue or a coil, or surgical resection with or without prior embolisation. 2,[8][9][10][11][12][13][14][15][16][17] The following case report describes an unusual cause of spontaneous oropharyngeal bleeding in a young dog, successfully treated with complete excision of the lesion via partial glossectomy.…”
