Conditions We Treat

Airway malformations include anomalies of the mandible (lower jaw), palate, oral cavity, or neck, or masses inside or outside the airway that compress on or obstruct the airway.

In most twins, each fetus has its own placenta (dichorionic placentation). Monochorionic twins, twins sharing a single placenta, develop when a single embryo splits early in gestation.

Congenital diaphragmatic hernia is a very serious condition that occurs when the diaphragm, the muscle that separates the abdomen from the chest, doesn’t develop as it should.

Spina bifida is a condition that happens when the fetus’s bony spine, which protects the spinal cord and nerves, doesn’t develop normally.

These are masses that grow inside or next to an unborn baby’s lung. They are commonly called bronchopulmonary malformations. Large and complex fetal lung masses can be associated with compression of the developing lung; development of fetal hydrops; polyhydramnios; preterm premature rupture of membranes (PPROM), a rupture of the amniotic sac before labor begins; and preterm birth.

Fetal hydrothorax occurs when fluid builds up within the fetal chest. The fluid can compress the developing lungs and shift the heart from its usual position (mediastinal shift). Compression of the lungs can interfere with their normal development.

This finding indicates a blockage in the fetus’s urinary tract, causing the bladder, ureters, and kidneys to swell with urine that can’t drain as it should. This can severely damage the kidneys and the developing lungs if the fluid around the baby decreases over time.

Fetal anemia is a low red blood cell count in the fetus. Fetal anemia most commonly results from an incompatibility between the mother’s blood and fetal blood (also known as isoimmunization), but it can also be due to infections and certain genetic conditions. Fetal anemia can lead to cardiac failure and fetal hydrops.

Some kinds of placental disorders (placenta previa, accreta, increta, and percreta) happen when a woman’s placenta grows across the cervix or is attached too deeply to the uterine wall. Placenta accreta is the mildest of the three.

How a heart condition affects a baby varies widely and depends on how severe the problem is, when it is diagnosed, and how it is treated. The likelihood of a child having a developmental disability or delay when he or she is older increases with how complex the heart defect is.
