[Arteriovenous aneurysm of the left internal thoracic artery with hypertrophy of the left upper limb (author's transl)].

Case report on a 5 years old boy suffering from a congenital arteriovenous fistula of the left internal thoracic artery. At the age of 9 months hypertrophy of the left arm combined with dilated veins in this area developed. Diagnosis was made by clinical examination together with a density in the left upper chest on x-ray and was confirmed by phlebography and thoracic aortography. A dilatation of the left heart, which was marked at the age of 9 months vanished in childhood without any therapy. The child was operated successfully.
