title: Radial artery pseudoaneurysm in a neonate with hemophilia A.
abstract: BACKGROUND
  Pseudoaneurysm formation is a rare complication of arterial puncture.
  
  
  METHODS
  3-week-old male developed an enlarging mass over the anterior aspect of left wrist following radial arterial puncture.
  
  
  METHODS
  Doppler ultrasonography revealed mass to be left radial arterial pseudoaneurysm. Subsequent presentation of ecchymoses and investigations confirmed factor VIII deficiency (Hemophilia A).
  
  
  RESULTS
  Pseudoaneurysm removed with primary end to end anastomosis. Patient is presently on regular factor VIII replacement therapy.
  
  
  CONCLUSIONS
  Hemophilia A can present as pseudoaneurysm in neonatal period.
