Primary pulmonary hypertension in infancy: report of two autopsy cases.
Two cases of unexplained plexogenic pulmonary arteriopathy in infancy were studied by patho-anatomical approach. The patients were boys, age 7 months and 2 years 2 months. Pulmonary arteries revealed Grade 3 and Grade 4 hypertensive changes, respectively, after Heath and Edwards' criteria. The configuration of the media of the pulmonary trunk suggested that though these cases were very young, pulmonary arterial pressure had been elevated since some time after birth.
