Iatrogenic left subclavian artery-to-left brachiocephalic vein fistula: successful repair without a sternotomy.

Subclavian vein catheterization can result in arteriovenous fistula formation--a rare complication that will eventually lead to heart failure if left untreated. The world medical literature describes several subclavian artery-to-subclavian vein fistulas and 2 subclavian artery-to-brachiocephalic vein fistulas, both on the right side. To our knowledge, there have been no reports of an iatrogenic left subclavian artery-to-left brachiocephalic vein fistula.
