The foetal anomaly scan refers to a detailed ultrasound scan carried out to take a closer look at your uterus and your developing baby between the 18th and 21st weeks of pregnancy. If you are pregnant, you can consider receiving the scan at the best maternity hospital in Bangalore. Here is everything you need to know about the procedure and its benefits.
Purpose
A foetal scan is performed to identify any abnormalities in your unborn baby.
Type of Scan
Technology is available to create both 2D and 3D images that may be coloured or monochromatic. This will depend on the chosen hospital.
Procedure
A sonographer puts a gel on your belly. Then he moves a transducer over it to get images of your baby.
Duration
If you visit the best maternity hospital in Bangalore for the scan, it will generally take just half an hour.
Areas of Focus
Baby’s Body Part Checked for
Shape and size of brain and head Brain problems
Face Cleft lip
Spine Bone alignment
Abdominal wall Whether it covers every internal organ situated at the front
Heart Whether the valves are functioning properly and the ventricles and the atria are equal in size
Kidneys Whether the bladder is functioning properly
Hands and feet Development of toes, fingers and muscles
Placenta Position
Amniotic fluid Sufficient quantity to allow the baby to move freely
Femur length; Circumference of the abdomen and head Compare with the standards of normal development
Benefits
A foetal anomaly scan can help detect certain problems in the unborn baby. Here is a list of them with the percentage of likelihood of detection:
- Anencephaly (an absence of the head’s top): 98%
- Cleft lip: 75%
- Missing or very short limbs: 60%
- Spinal defects: 90%
- Major kidney problems: 84%
- Chromosomal abnormalities: 95%
- Major heart problems: 50%
Sometimes, the scan also helps the sonographer detect abdominal defects in the baby.
Results
Usually, no anomaly is detected and babies are reported to develop normally. If a birth defect is suspected, the sonographer goes for a second opinion from a specialist or an experienced colleague.
However, keep in mind that the scan is not full-proof. So, the baby might be born with an undetected birth defect. But receiving the scan at the best maternity hospital in Bangalore reduces the chances of such flaws.
What Happens If a Problem is Found?
If an anomaly is detected, other scans or tests might be recommended to understand the condition better. Once the problem is confirmed, further action will be taken based on its severity. Less critical conditions often improve by themselves. In the case of critical anomalies, support is provided to the family. They are educated about every possible course of action, even the termination of pregnancy. The family gets enough time to make a decision and that is respected.
Identifying anomalies before childbirth helps in planning post-birth treatment. This is particularly helpful in cases where surgery right after birth can improve the chances of your baby’s recovery or survival. Therefore, make sure to receive the scan at the right time during pregnancy.
