Abstract
We report a case with severe persistent pulmonary hypertension (PPHN) associated with congenital cystic adenomatoid malformation of the lung (CCAM) treated with sildenafil PO. The case was unresponsive to the High-Frequency Oscillatory Ventilation (HFOV), with a oxygenation index (OI) of 50 before sildenafil. Substantial improvement in OI was followed by extubation and survival. No side-effects were noted.
