VP14.02: Counselling on congenital diaphragmatic hernia: obstetric outcomes and the use of observed to expected lung‐to‐head ratio in a contemporary cohort

Abstract

Objectives: Congenital pulmonary airway malformations (CPAM) is a rare developmental malformation of lower respiratory tract. During lung morphogenesis abnormal airway patterning and branching result in lung cysts. Incidence quoted is 1 per 25000 to 35000 live births. However, among all congenital cystic lung lesions CPAM accounts for 95% during prenatal screening at 18 to
