Fetal Barcelona Calculator

[Oreo Huppe]

TheMCA calculator assesses the risk of fetal anemia in both single and twin pregnancies. Our calculations are based on a Middle Cerebral Artery (MCA) Doppler scan performed during routine pregnancy checkups.

MCA stands for the Middle Cerebral Artery. It's one of the three biggest vessels supplying the brain with blood, and it's very visible during fetal ultrasounds. Its measurements are used to check the well-being of the child.

A Doppler ultrasound is a type of ultrasound technique that allows us to visualize the blood flow and its velocity. We use the movement of red blood cells inside the blood vessels to obtain this data.

Perinatology and MCA are long-time friends; Doppler ultrasounds are used both for regular check-ups and for more specific, detailed diagnostics. The middle cerebral artery is assessed for a number of reasons:

All of the above states result in hypoxia, an inadequate supply of oxygen to the body of the fetus. The fetus's body is trying to protect their most essential organs, such as the brain, heart, and lungs. To achieve this, the baby redirects the blood flow into these organs to obtain the best supply of blood possible.

In the most severe cases, the blood flow is so limited that we cannot detect any sign of blood flow inside the brain's blood vessels, as the flow observed during the diastole is retrograde. This state is very serious and requires immediate medical attention.

Fetal anemia is a condition in which the fetus's red blood cells are destroyed too quickly. The most common reasons in the US for fetal anemia are a parvovirus infection or a RH conflict. ?

Nevertheless, the best method is to prevent fetal anemia by proper immunization of all Rh- women after every pregnancy or miscarriage. You should also avoid any sources of parvovirus while pregnant.

The traditional method to calculate the median MCA peak systolic velocity is through medical research. MCA ultrasound measurements are taken at respective weeks of the pregnancy in a group of hundreds or thousands of women. We need to take into account their ethnicity, age, number of fetuses, and weight.
