uteroplacental insufficiency
Decreased blood flow from mother to placenta, affecting fetal oxygenation and growth.
Full Definition
Uteroplacental insufficiency refers to inadequate blood flow from the maternal circulation to the placental intervillous space, resulting in decreased oxygen and nutrient delivery to the fetus. This condition may be chronic (leading to IUGR) or acute (causing fetal distress). In fetal surgery, uteroplacental insufficiency can develop due to maternal positioning, anesthetic effects, or surgical manipulation of the uterus. Recognition requires monitoring fetal heart rate patterns, umbilical artery Doppler studies, and maternal hemodynamic parameters.
Usage
Usage note: Distinguish between acute intraoperative and chronic antepartum presentations.
