An acquired arteriovenous fistula between the distal collateral radial and median arteries arising from the brachial artery, and the cephalic, brachial and median cubital veins of the right foreleg in an 8‐year‐old Afghan Hound is described. The arteriovenous fistula was apparently acquired two years previously after a perivascular injection of the anaesthetic agent thiopentone sodium in 5 per cent W/V solution* and was found as an incidental problem during an examination for an unrelated lameness problem. The arteriovenous fistula was characterized by a large pulsatile swelling that had a continuous thrill and bruit. A positive Branham sign was present. The lesion was diagnosed by physical and radiological examination. Ligation of the brachial artery has provided some post‐operative improvement in exercise tolerance.
