[Suspected SIDS diagnosis--van Praagh I truncus communis as a nonfatal incidental finding].

Autopsy of a baby suspicious to SIDS. Most interesting postmortem finding was a congenital malformation of the great vessels, a truncus arteriosus communis typus van Praagh A I. That one is very rare with a clinically frequency of only 1.7%. The malformation was not cause of death and was statistically survived for 2 months. The baby died of aspiration resultant from an incarcerated inguinal hernia.
