polyhydramnios
Excessive accumulation of amniotic fluid, often associated with fetal anomalies or maternal conditions.
hydrops fetalis
Abnormal fluid accumulation in fetal tissues and body cavities, often indicating severe fetal compromise.
hysterotomy
Surgical incision into the uterus to access the fetus for in utero repair procedures.
iatrogenic
Complications or conditions caused by medical treatment or intervention, including fetal surgical procedures.
intraamniotic pressure
Pressure within the amniotic cavity monitored during fetal surgical procedures.
intraoperative ultrasound
Real-time ultrasound imaging performed during fetal surgery to guide needle placement, monitor fetal position, and asses...
intrauterine transfusion
Procedure to deliver blood products directly to an anemic fetus via umbilical cord or intraperitoneal access.
IUGR
Intrauterine growth restriction; fetal growth below expected parameters, affecting surgical timing and outcomes.
laser photocoagulation
Fetoscopic procedure using laser energy to ablate abnormal placental vascular connections in twin pregnancies.
lung-to-head ratio
Ultrasound measurement used to assess fetal lung development, particularly in cases of congenital diaphragmatic hernia.
MAP
Mean arterial pressure; critical hemodynamic parameter monitored during maternal anesthesia for fetal surgery.
maternal laparotomy
Surgical opening of the maternal abdomen to access the gravid uterus for fetal intervention.
maternal mirror syndrome
Maternal condition mimicking fetal hydrops, requiring immediate delivery consideration.
maternal positioning
Strategic placement of the pregnant patient during fetal surgery to optimize surgical access while maintaining uteroplac...
maternal-fetal surgery
Surgical procedures performed on pregnant women that directly access and treat the fetus while in utero.
membrane repair
Surgical restoration of amniotic membrane integrity following fetal procedures to prevent amniotic fluid leakage and red...
membrane sealant
Biocompatible material applied to seal fetal membrane defects and prevent amniotic fluid leakage after surgery.
membrane separation
Iatrogenic separation of chorion and amnion layers, a potential complication of fetal surgical procedures.
minimally invasive fetal surgery
Surgical approach using small incisions and specialized instruments to perform fetal interventions with reduced maternal...
MOMS trial
Landmark randomized controlled trial demonstrating benefits of prenatal versus postnatal myelomeningocele repair.
myelomeningocele
Severe form of spina bifida where spinal cord and meninges protrude through an opening in the spine, commonly treated wi...
neural placode
Exposed neural tissue in spina bifida cases that requires surgical protection during fetal repair.
neuroprotection
Strategies to minimize neurological injury during fetal neurosurgical procedures.
oligohydramnios
Decreased amniotic fluid volume that may complicate fetal surgical procedures and recovery.
placental abruption
Premature separation of the placenta from the uterine wall, a serious complication that can occur after fetal surgery.
