| Abstract |
|
Persistent pulmoanry hypertension of the newborn (PPHN) is a syndrome consisting of severe
hypoxemia and pulmoanry hypertension that appears within hours of birth.
The essential pathophysiologic features of this syndrome is pulmonary artery hypertension causing
right-to-left shunt through the patent ductus arteriosus or foramen ovale or both and clinically
manifested by central cyanosis and respiratory distress.
We recently have experienced 20 hour old female and 7 hour old male babies presented with
cyanosis and respiratory distress soon after birth.
Each case had evidence of pulmonary artery hypertension with right-to-left shunt, by both clinical
examination and echocardiography.
The 20 hour old female was suggested the primary type of PPHN, contrast echocardiogram showed
right-to-left shunt through the foramen ovale and finally improved to dischage without complication.
The other was thought the secondary type of PPHN due to meconium aspiration syndrome and the
autopsy findings were consistent with intra-acinar pulmonary arterial muscularization, probably
resulting from intrauterine hypoxia.
A brief review of related literatures is given. |
