Question 1

Risk factors for gastroschisis

Answer 1

young maternal age, smoking and use of vasoactive agents

Question 2

What is gastroschisis?

Answer 2

Fetal gastroschisis is defined as full thickness anterior abdominal wall defect with
bowel protruding through the defect

It usually occurs on the right side of a normally inserting umbilical cord

The defect is not covered by membrane

Question 3

Special considerations if gastroschisis identified

Answer 3

10% still birth rate
If no other abnormalities, likelihood of genetic cause or syndrome is low
Once born, cover with a plastic bag. May be suitable for primary closure. Need to deliver in a unit with paed surgery.

Question 4

Chorioid plexus cyst

Answer 4

Incidence 1-3%
Soft marker- most fetuses will not have an abnormality but there is an association with trisomy 18
Should have tertiary anatomy scan

Question 5

Echogenic bowel

Answer 5

• If found in 3rd trimester- no significance
• Second trimester- in a normal fetus has no sequelae
• Can however be associated with increased risk of chromosomal and non chromosomal fetal
  abnormalities
• Causes: - Genetic e.g. aneuploidy
• Non genetic: intra-amniotic bleeding, CF, congenital malformations of the bowel e.g. Hirschprungs, IUGR, congenital infection

Need increased surveilance due to increased risk of IUGR and fetal death
