Species: Dog
Condition: Arteriovenous Fistula
Organ System: Cardiovascular
It is an abnormal, low resistance connection between an artery and a vein. If the fistula is large enough, a large percentage of the total blood from the heart bypass the capillary bed, resulting in tissues receiving reduced amounts of oxygen, or none at all. This causes the heart to compensate for the lack of oxygen in the tissues by pumping blood for circulation at a faster rate, which can increase a dog’s predisposition to ‘high output’ congestive heart failure. Dogs typically acquire fistulae as a result of traumatic damage to blood vessels, tumors, surgery complications, injection (e.g barbiturates) around blood vessels, or from drawing blood.
