5 Fetal Abdominal Wall Sonography
Conclusion
Abdominal wall defects are a complex group of congenital anomalies with a broad spectrum of manifestations and outcome. First step is evaluation of the cord
insertion site in relation to the defect. The defects
involving cord insertion are omphalocele, cloacal
exstrophy, Pentalogy of Cantrell, abdominoschisis and
body stalk anomaly. Omphalocele as an isolated defect
has good prognosis. In cloacal exstrophy, the associated
defect is inferior and in Pentalogy of Cantrell, the defect
is superior. The defects with intact cord insertion are
gastroschisis and bladder exstrophy. Absent urinary
bladder is a nding in both bladder and cloacal exstrophy. Fixed fetal position and undenable anatomic parts
are hallmarks of abdominoschisis due to Amniotic Band
syndrome and Body Stalk Anomaly. Recognition of
more complex AWDs is vital in pregnancy counselling
and management.
