intrauterine transfusion
Also written as: IUT — intrauterine transfusion
Procedure to transfuse blood directly into the fetus to treat severe anemia.
Full Definition
A therapeutic procedure performed under ultrasound guidance to deliver red blood cells directly into the fetal circulation, typically through the umbilical vein. This intervention is used to treat severe fetal anemia caused by conditions such as red blood cell alloimmunization, parvovirus infection, or alpha-thalassemia major. The procedure can be life-saving for the fetus and may need to be repeated multiple times during pregnancy. Complications include fetal loss, preterm labor, and infection, making careful patient selection and expert technique essential.
Usage
Usage note: Specify the transfusion route (intravascular vs. intraperitoneal) when clinically relevant.
