Fetal Diagnosis & Treatment

Twin to Twin Transfusion Syndrome (TTTS): Twin –Twin Transfusion Syndrome (TTTS) is a serious complication of twin pregnancies where the babies share a placenta (monochorionic). TTTS occurs in 10-15% of these pregnancies. Read more on the diagnosis of TTTS and available treatment options.
Twin Reversed Arterial Perfusion Sequence (TRAP): Twin Reversed Arterial Perfusion Sequence (TRAP) occurs solely in monochorionic twin pregnancies. It is an extremely rare problem with an incidence of about 1 in 35,000 pregnancies and only about 1% of monochorionic twin pregnancies. In TRAP, there is one twin that has developed normally and the other that has severe anomalies. Continue reading about the diagnosis and treatment of TRAP.
Congenital Diaphragmatic Hernia (CDH): Congenital Diaphragmatic Hernia (CDH) is a severe birth defect that affects 1 in every 2500 babies. Congenital CDH occurs when the diaphragm does not fully form, allowing organs to enter the chest cavity preventing lung growth.
Intrauterine Fetal Transfusions (IUT): Intrauterine transfusions are blood transfusions that are used to replace fetal red blood cells. Transfusions can be done in the fetal abdomen, but are more typically done in the umbilical vein. They are usually done every 1-4 weeks until delivery. Continue reading about fetal anemia and intrauterine fetal transfusions.
Obstructive Uropathy (fetal bladder shunts): Obstruction to urine flow which may result in severe kidney damage (renal dysplasia) and underdevelopment of the lungs (pulmonary hypoplasia). Fetal bladder shunts are used to bypass the obstruction and can prevent the detrimental effects on fetal lung and kidney development.
