We present a case of arterial thrombosis of the upper extremity in a 1-day-
old neonate. The initial response to thrombolytic and anticoagulant therapy
alone was unsuccessful. Distal flow to the extremity was reestablished by
combined percutaneous transluminal angioplasty of the subclavian artery usi
ng transumbilical access followed by resumption of the thrombolytic and ant
icoagulant regimen. (C) 2000 Wiley-Liss, Inc.
