intrauterine transfusion

Full Definition

A therapeutic intervention where packed red blood cells are transfused to a fetus suffering from severe anemia, typically due to red cell alloimmunization, parvovirus infection, or twin-to-twin transfusion syndrome. The procedure can be performed via intravascular access through the umbilical vein (most common) or by intraperitoneal injection. Careful monitoring of fetal heart rate, hematocrit levels, and procedural complications is essential.

Usage

Usage note: Often abbreviated as IUT; specify approach (intravascular vs. intraperitoneal) in documentation.
