For pregnancy control, we perform an obstetric ultrasound that provides us a large amount of information and does not have negative or damaging effects for the mother and fetus.
The number of ultrasound scans that must be performed during the pregnancy will depend on each specific case and whether there is any risk factor, although the SEGO (Spanish Gynaecological and Obstetrics Society) recommends that at least three ultrasonographic exams be performed, one in each trimester of the pregnancy. These are usually performed at week 12, week 20 and week 32-34 of gestation.
We also perform prenatal diagnosis/screening using several techniques and highly specialised tests, providing the earliest possible diagnosis of different diseases, abnormalities, or genetic alterations that may affect the fetus. To that end, we have two very precise techniques such as high resolution ultrasound, Doppler and analysis to detect genetic problems in the amniotic fluid (amniocentesis/fish) or in maternal blood (non invasive prenatal testing).
3D/4D ultrasound or “emotional ultrasound” is used to see the fetus in three dimensions and in real time, being able to see the features, gestures and movements. The best time to perform a 3D is between weeks 26 and 28 of gestation, earlier if it is a twin pregnancy, as that is the time when there is the greatest possibility of obtaining higher quality images.
At Clínica el Sur Sevilla, in addition to enjoying images in real time the exam is recorded on DVD and delivered along with the images of the fetus on paper. At the same time, we take advantage of the examination to evaluate fetus growth and wellbeing at that moment.
Three-dimensional images of the fetus may also be very useful in cases of fetal malformation, as they may help parents to understand and visualise the existing defects if any.
