Finally, we compared the VEGF values of fetuses with CDH that underwent tracheal occlusion with those that did not and found that the differences were not statistically significant (2.43 ± 0.66 pg/μg versus 2.20 ± 0.81 pg/μg; P = 0.27) (Figures 7 and 8). Here, VEGFA is linked to congenital diaphragmatic hernia.
