The relationship between the Obstetrician and the Fetal Medicine specialist: two areas that complement each other in caring for the same life.

Dr. Andre Miyague December 3, 2025

When a pregnant woman arrives at the doctor's office for the first time, she brings with her a mixture of joy, expectation, and worry. And it is precisely at this beginning that a common question arises: What is the difference between an obstetrician and a doctor specializing in fetal medicine?

They both participate in the same pregnancy, care for the same baby, and walk together, but each with a very specific role.

It is about this partnership that I want to talk here. To explain how we complement each other, why we work side by side, and how this relationship ensures greater safety, diagnostic accuracy, and peace of mind for the family.

Fetal tumors: when diagnosis is not a death sentence.

Dr. Andre Miyague September 25, 2025

Receiving the news of a "tumor in the baby" while still in the womb naturally evokes fear and insecurity. It's a powerful word, loaded with meaning and often immediately associated with something malignant.

But it's not always like that.
In fetal medicine, many tumors diagnosed during pregnancy are benign and can be safely monitored until birth.

In this article, I want to clearly explain what fetal tumors are, where they usually appear, what risks are involved, and, most importantly, how we can best care for them with responsibility, planning, and hope.

Because before anything else, it's important to understand what this result actually means.

Fetal Growth Restriction: when the baby stops growing... even at a normal weight.

Dr. Andre Miyague April 4, 2025

Folks, when we talk about Fetal Growth Restriction, it's very common to only think about that visibly small, thin baby with a lower than expected weight. But the truth is that the case isn't always that obvious.

I had the opportunity to speak about this topic at the 6th Ultrasound Conference of the Brazilian Society of Ultrasound in Paraná – SOPRUS 2025, here in Curitiba. And wow… it was special to be able to share this subject with colleagues, a subject that is increasingly appearing in our daily practice.

Today, I want to share with you some important points from the lecture. Because understanding how fetal growth restriction (FGR) works—especially late-stage FGR—can completely change the outcome of a pregnancy.
