CDH Part 3: CDH Pulmonary Hypertension


Congenital Diaphragmatic Hernia, or CDH, is
a birth defect that allows abdominal organs to pass through the diaphragm, enter the chest,
and inhibit lung growth. This can cause breathing problems after birth.
This can cause two main complications: Pulmonary Hypoplasia, and Pulmonary Hypertension, which
means “high blood pressure in the lungs.” Before a baby is born, it receives oxygen
from its mother, not from its lungs. The baby’s blood flows from its heart, bypasses the lungs,
and flows to its body. This is possible because of special fetal connections that let the
blood skip the lungs. After birth, these connections close. The
blood now flows through the lungs, picks up oxygen, flows back to the heart, and out to
the body. But with Pulmonary Hypertension, the blood
vessels in the lungs are so small that pressure starts to build up. This pressure causes the
fetal connections to remain open. After birth, blood continues to flow through the old fetal
connections, bypassing the lungs, reducing the amount of oxygen delivered to the baby’s
body. The severity of this condition requires a
comprehensive approach. At the Colorado Fetal Care Center, our dedicated, multidisciplinary
team has some of the best outcomes in the nation in caring for and treating CDH and
its multiple effects. Visit coloradofetalcarecenter.org for more
