pleuroperitoneal hiatus

(redirected from Bochdalek foramen)

pleur·o·per·i·to·ne·al hi·a·tus

an opening through the diaphragm, connecting pleural and peritoneal cavities, usually the result of defective development of the pleuroperitoneal membrane in the embryo; if the defect is extensive there may be herniation of digestive organs into the pleural cavity.
See also: diaphragmatic hernia.
Synonym(s): Bochdalek foramen

pleuroperitoneal hiatus

a posterolateral opening in the fetal diaphragm. Its failure to close leaves a congenital posterolateral defect that may become a site for a congenital diaphragmatic hernia. Also called foramen of Bochdalek.
