Anomaly scan nhsmail

An anomaly scan, also known as a detailed ultrasound scan, is a routine prenatal test performed between 18-22 weeks of pregnancy to detect any potential abnormalities or anomalies in the fetus. The National Health Service (NHS) in the UK offers this scan as part of their maternity care services.

Here's what you can expect during an anomaly scan:

What is checked during the scan?

During the scan, the sonographer (a trained healthcare professional) will examine the fetus for any signs of abnormalities or anomalies in various parts of the body, including:

1. Head and brain: The sonographer will check for any structural abnormalities, such as hydrocephalus (excess fluid in the brain) or microcephaly (small head).
2. Heart: The scan will assess the heart's structure and function, looking for any defects or abnormalities.
3. Abdomen: The sonographer will check for any abnormalities in the liver, gallbladder, pancreas, and kidneys.
4. Limbs: The scan will examine the arms, legs, and fingers for any abnormalities, such as clubfoot or polydactyly (extra fingers or toes).
5. Face and ears: The sonographer will check for any facial abnormalities, such as cleft palate or lip, and assess the ears for any structural issues.
6. Spine and skeleton: The scan will examine the spine and skeleton for any abnormalities, such as spina bifida or skeletal dysplasias.

What are the risks and benefits?

The anomaly scan is a safe and non-invasive procedure, but like any medical test, there are some risks and benefits to consider:

Benefits:

• Early detection of potential abnormalities, allowing for early intervention and treatment
• Reduced anxiety and uncertainty for parents-to-be
• Improved pregnancy outcomes and reduced risk of complications

Risks:

• False positives or false negatives (although rare)
• Emotional distress or anxiety related to the scan results
• Potential need for further testing or invasive procedures (e.g., amniocentesis) if abnormalities are detected

What happens if an anomaly is detected?

If an anomaly is detected during the scan, the sonographer will discuss the findings with you and your healthcare provider. Depending on the severity and type of anomaly, you may be referred to a specialist for further evaluation and treatment. In some cases, the anomaly may not require any treatment, while in others, it may require prenatal testing, delivery planning, or postnatal care.

Remember, the anomaly scan is a routine part of prenatal care, and the vast majority of pregnancies result in healthy, normal babies. If you have any concerns or questions, be sure to discuss them with your healthcare provider or sonographer.
