In most cases the outcome of a fetus with CCAM is very good. However in a rare few cases the cystic mass grows so large as to limit the growth of the surrounding lung and cause preassure against the heart. In these situations, the CCAM can be life-threatening for the fetus. DIAGNOSIS CCAMs are often identified during routine prenatal Ultrasonography . Indentifying characteristics on the sonogram include: an echogenic (bright) mass appearing in the chest of the fetus, displacement of the heart from its normal position, a flat or everted (pushed downward) diaphragm, or the absence of visible lung tissue. TREATMENT In most cases, a fetus with CCAM is closely monitored during pregnancy and the CCAM is removed via surgery after birth. A few fetuses may develop fluid collections within the chest cavity and in those situations a Harrision catheter shunt can be used to drain the fluid into the amniotic fluid. Very large cystic masses might pose dangerous during birth because of the airway compression. In this situation, a special surgical type of delivery called the EXIT Procedure may be used. In rare extreme cases, where fetus's heart is in danger, Fetal Surgery can be performed to remove the CCAM. EXTERNAL LINKS |
