title: Correction of truncus arteriosus with autologous arterial flap in neonates and small infants.
abstract: BACKGROUND
  This study describes the results of techniques using the autologous truncal wall and part of the pulmonary artery for correction in anticipation of the growth of the pulmonary tract in patients with truncus arteriosus.
  
  
  METHODS
  Seven consecutive patients with truncus arteriosus were reviewed. The posterior wall of the pulmonary tract was obtained by anastomosing the lower edge of the truncal arteriotomy to the upper corner of the ventriculotomy from the truncus in types I and II. Anterior translocation of the pulmonary artery was performed in a type III. A pericardial patch with or without a monocusp was placed to complete the right ventricular outflow tract.
  
  
  RESULTS
  There were two hospital deaths, one of which was unrelated to a cardiac problem. Postoperative right-to-left ventricular peak pressure ratio was less than 0.55. There was one left pulmonary stenosis due to monocusp adherence in the late postoperative period. The sizes of the pulmonary tract at anastomosis were between 107% and 166% of the normal value between 7 months and 3.8 years of follow-up.
  
  
  CONCLUSIONS
  The use of autologous arterial wall instead of a conduit is recommended for the repair of truncus arteriosus to expect growth of the pulmonary tract.
