A Viability Scan is a medical imaging technique that is used to assess the health and development of an embryo. It can provide valuable insight into the successful implantation, growth, and development of a foetus in early pregnancy. Utilising ultrasound technology, the viability scan identifies potential problems affecting the developing baby before they become more serious. This scan offers reassurance that a healthy pregnancy is underway and that there are no signs of any complications.

Types of Viability Scan

There are three main types of Viability Scan: Early Pregnancy Scan (7-10 weeks), 12 Week Nuchal Translucency Scan and Reassurance Scans (15-23+ weeks). An Early Pregnancy Scan is used to check the viability of an early pregnancy, while a 12-week Nuchal Translucency Scan checks for any signs of chromosomal abnormalities. Finally, Reassurance Scans are used to check the growth and well-being of the baby from 15 weeks on.

Treatment options for Viability Scan

Treatment options based on the viability scan depend on the individual patient and their medical history. Generally, a viability scan can detect any issues with the pregnancy, allowing for early diagnosis and treatment of any problems. Common treatments include monitoring the pregnancy, changes in lifestyle or diet, hormone therapy, and medications. In more serious cases, surgical interventions such as dilation and curettage (D&C) may be recommended to remove abnormal tissue from the uterus. If required, further testing such as amniocentesis may be recommended to determine the health of the baby.

Risk factors for Viability Scan

The main risk factors for a viability scan are incorrect positioning of the baby in the womb, poor quality ultrasound equipment, and incorrect timing of the scan. The scan can also produce false results if there is a placenta or fibroids in the uterus, or if there is too much amniotic fluid. Furthermore, it may be difficult to accurately assess the health of a foetus if the mother has a high BMI or abdominal scar tissue. Lastly, if maternal structures are blocking the view of the foetus, then it may not be possible to carry out a viability scan.

Who qualifies for a Viability Scan?

A viability Scan is typically recommended for pregnant women who are 6 to 12 weeks into their pregnancy. It can be used if there is a concern about the health of the developing foetus or to confirm the viability of a pregnancy that has been detected but is not yet visible on ultrasound. The procedure is also commonly used during assisted reproductive technologies like IVF, as it allows doctors to check the embryo's development and ensure successful implantation.

How should one prepare for a Viability Scan?

Before a viability scan, the patient should avoid eating and drinking for at least four hours. It is best to wear comfortable clothing that can be easily removed from the waist down. The patient should empty their bladder before the scan and bring an ultrasound-safe lubricant if preferred. It is important to note that no preparation is needed for a transvaginal scan, but it is advised to have a full bladder for a transabdominal scan.

Benefits of a Viability Scan

A viability Scan is an ultrasound that helps determine the health of a pregnancy. It can detect the heartbeat of an embryo, confirm the gestational age, and assess the risk of miscarriage. It also allows for accurate dating of pregnancies and can detect multiple pregnancies. In addition, it can help identify potential problems such as ectopic pregnancies or placental abnormalities. A viability scan is beneficial because it accurately confirms that the pregnancy is healthy and viable, providing reassurance to expecting mothers.

Conclusion

A Viability Scan is an important exam that can provide valuable insight into the health and potential of pregnancy. It uses ultrasound technology to measure the heartbeat, check for multiples, and assess the size of the gestational sac to determine if a pregnancy is viable. This scan can give peace of mind to expectant parents and help them prepare for the journey ahead. With the help of a trained medical professional, this scan is an essential part of monitoring the health and progress of any pregnancy.

1. What types of information does a viability scan provide?

A viability scan provides information about the presence of a viable intrauterine pregnancy, including gestational age and the number of foetuses.

2. How accurate is a viability scan?

Viability scans are highly accurate when performed between 6-12 weeks of gestation, with an accuracy rate of 95%.

3. Is a viability scan painful or uncomfortable?

No, a viability scan is non-invasive and considered to be painless. It can cause some slight discomfort due to pressure from the transducer, but no lasting effects should be expected.

4. Can other conditions or abnormalities be detected during a viability scan?

In addition to providing information about the presence of a viable intrauterine pregnancy in early pregnancy, some other conditions, such as ectopic pregnancies or miscarriages, can also be detected during a viability scan.
