[Pathogenesis of congenital diaphragmatic hernia of the newborn infant: apropos of 2 cases].

On two personal cases of left diaphragmatic congenital hernia, the authors study the innervation of the diaphragm. They describe a lower number of fibres in the phrenic nerve on the side of the malformation and don't find any branches coming from the intercostal nerves. This malformation is probably of neurogenic origin.
