I am scheduled to have a Congenital Anatomy Scan tomorrow at Asian Hospital and I hope results are what I hope for. This is just a standard procedure from my OB but of course I can’t help but be worried. According to this site:

This scan is used to detect abnormalities of the baby and it is often performed at around 22 weeks. Most babies are healthy but sadly some have serious problems, which almost always cannot be predicted by a family history of the health of the mother.

Approximately 70 per cent of all serious congenital malformations can be detected by this scan. Thus, even if the baby appears normal on this scan there is still a small chance that your baby will have a problem.

Sometimes it is difficult to obtain optimal views of a certain part of the baby’s anatomy if the baby is in an awkward position. Rarely it might be necessary to come back for a repeat scan so as to complete the examination.

The sex of the baby can almost always be determined on scanning at 20 weeks but Mr Economides will only tell you if you wish to know this information.

A table is included below of some of the problems that can be detected on ultrasound at 20 weeks and the likelihood of detection. (RCOG 2000)

Problem Observation Detection Rate
Open spina bifida Open spinal cord 90 per cent
Anencephaly Missing top of head 99 per cent
Hydrocephalus Excess fluid within the brain 60 per cent
Congenital heart disease Major heart defect 60 per cent
Exomphalos/gastroschisis Defect of the abdominal wall 90 per cent
Major kidney problems Missing or abnormal kidneys 85 per cent
Major limb abnormalities Shortened or abnormally formed bones 90 per cent
Diaphragmatic hernia Defect of the muscle separating chest and abdomen 65 per cent
Cleft lip and palate Defect in lip 80 per cent
Down’s syndrome Heart, limb, and bowel problems 50 per cent
Cerebral palsy Not detected
