Plain-English summary
Three pets, including two dogs and one cat, were taken to a specialized veterinary center because they had swollen limbs, some bleeding skin lesions, and were sometimes limping. They were diagnosed with a condition called peripheral arteriovenous anomaly (PAA), which was confirmed using advanced imaging. To treat this, one dog had a vein tied off, while the cat and the other dog received a special glue treatment to block the abnormal blood flow. After the procedures, all pets showed improvement, with their symptoms disappearing and no complications noted during follow-up visits that lasted between 6 and 55 months. Overall, the treatments were successful.
Abstract
Two dogs and 1 cat were referred to a tertiary veterinary center for the consultation and treatment of limb edema, variable dermal sanguineous crusting lesions, and intermittent lameness. A peripheral arteriovenous anomaly (PAA) was diagnosed via computed tomographic angiography (CTA) in each case. Arteriography enabled further evaluation of the PAA with confirmation of a dominant outflow vein. Dominant outflow vein occlusion was achieved by direct ligation in 1 dog and retrograde transvenous glue embolization in the cat and other dog. Repeat arteriography demonstrated resolution of arteriovenous shunting. Presenting clinical signs resolved in all animals. The previously identified aberrant vessels in 1 dog were not identified after CTA 40 days postoperatively. No postoperative complications or recurrence was identified in any case during the 6- to 55-month follow-up period.
