When uncertainty generates more anxiety than severity: the prenatal experience with cystic adenomatoid malformation of the lung.

Aim: To assess reasons for higher levels of anxiety generated by prenatal counselling of a condition with good outcome such as cystic adenomatoid malformation (CCAM) of the lung compared to a life-threatening malformation such as congenital diaphragmatic hernia (CDH). Materials and methods: The Spielberger State-Trait Anxiety Inventory (STAI-S) was used to measure anxiety in two groups of mothers carrying a fetus with the respective malformation. Results: Forty-four mothers completed the questionnaire (CCAM, n = 21 and CDH, n = 23). Before consultation, the mean STAI-S scores in the CCAM group (44.80 +/- 5.92) and in CDH group (44.05 +/- 4.96) were not significantly different but was significantly reduced in both groups after consultation (CCAM 44.80 vs. 41.60, P = 0.014 and CDH 44.05 vs. 34.35, P = 0.0001). The groups were not significantly different regarding gestational age at diagnosis. Conclusions: After initial prenatal counselling, uncertainty about prenatal outcome and lack of defined management plans in CCAM seems to be more important than higher mortality rate occurring in CDH.
