PLUG procedure
Percutaneous fetoscopic endoluminal tracheal occlusion to promote lung growth in severe congenital diaphragmatic hernia.
polyhydramnios
Excessive accumulation of amniotic fluid, often associated with fetal anomalies or maternal conditions.
PORT access
Minimally invasive surgical approach using small uterine incisions for fetal procedures.
posterior urethral valves
Congenital urethral membrane obstruction in male fetuses causing severe urinary tract dilation and oligohydramnios.
preterm premature rupture of membranes
Rupture of fetal membranes before 37 weeks gestation, a serious complication following fetal surgical procedures.
pulmonary hypoplasia
Underdevelopment of lung tissue resulting in reduced lung size and impaired respiratory function at birth.
Quintero staging
Classification system used to grade the severity of twin-to-twin transfusion syndrome for treatment planning.
radiofrequency ablation
Minimally invasive technique using thermal energy to ablate abnormal fetal tissues or vascular connections.
sacrococcygeal teratoma
Congenital tumor arising from the tailbone region that may require fetal surgical intervention in severe cases.
selective fetal growth restriction
Condition in twin pregnancies where one twin exhibits significantly impaired growth compared to its co-twin.
shunt placement
Surgical insertion of a drainage device to divert fluid from one body cavity to another in fetal patients.
spina bifida
Neural tube defect where spinal cord and surrounding structures fail to close properly during fetal development.
staple line
The sealed tissue junction created by surgical staplers during fetal surgery procedures. Critical to preventing amniotic...
thoracoamniotic shunt
A catheter placed between the fetal thorax and amniotic cavity to drain pleural effusions or decompress lung lesions.
tocolysis
Medical suppression of uterine contractions to prevent preterm labor following fetal surgery.
TRAP sequence
Twin reversed arterial perfusion causing acardiac twin formation in monochorionic pregnancies.
twin-to-twin transfusion syndrome
Serious complication of monochorionic twin pregnancies requiring urgent fetal intervention to prevent perinatal morbidit...
two-team approach
Surgical strategy employing separate obstetric and pediatric surgical teams to simultaneously address maternal and fetal...
uterine atony
Loss of uterine muscle tone resulting in inadequate contraction, a serious complication following fetal surgery.
uterine entry technique
Surgical approach method for accessing the fetal compartment during open fetal surgery, typically involving stapled or s...
uterine incision
Surgical opening of the uterine wall to access the fetus during open fetal surgery procedures.
uterine irritability
Increased uterine contractility following fetal surgery requiring tocolytic management.
uteroplacental insufficiency
Decreased blood flow from mother to placenta, affecting fetal oxygenation and growth.
