[A congenital arteriovenous fistula between the subclavian artery and vein. Its successful surgical correction in an infant].

The case of an asymptomatic 6-month-old boy, first seen due to a right arm edema is described. A continuous murmur heard at the right infraclavicular area, cardiomegaly plus increased flow to the lungs on the chest X-ray were associated with an isolated right subclavian artery-to-vein fistula diagnosed at angiography. Successful ligation of the fistula was done at operation with normalization of the arm circumference and heart size on the chest X-ray at 4 years follow up.
