Abnormal Passage Between Artery and Vein in Dogs




Dogs with clinical signs must undergo surgery to divide and remove abnormal connections between blood vessels. However, surgery can be difficult and labor-intensive and may require blood transfusions. While often successful, the arteriovenous fistula may recur even after surgery. Some dogs may even require amputation of the affected appendage.


A newer treatment option called transcatheter embolization involves using a catheter to block blood vessels. This method is particularly advantageous because it is relatively noninvasive and provides access to remote lesions via the blood vessels.


Living and Management


Your veterinarian will want to schedule regular follow-up appointments to evaluate your dog, especially if it underwent surgery. This will also enable him or her to determine whether the arteriovenous fistula has recurred.
