fetoscopy

 [fe-tos´kah-pe]
viewing of the fetus in utero by means of the fetoscope; this is now only rarely done, having been replaced by percutaneous umbilical blood sampling. adj., adj fetoscop´ic.

fe·tos·co·py

(fē-tos'kŏ-pē),
Use of a fiberoptic endoscope to view the fetus and the fetal surface of the placenta transabdominally, and also for collection of fetal blood from the umbilical vein for antenatal diagnosis of fetal disorders.

fetoscopy

Obstetrics An imaging technique in which a ultrasound-guided, 3 mm in diameter needle with an endoscope is inserted through the abdominal wall into the uterus to view a living fetus; fetoscopy can be performed in the 2nd and 3rd trimesters of pregnancy and carries a significant risk of fetal wastage, related to rupture of fetal membranes. Cf Embryoscopy.

fe·tos·co·py

(fē-tos'kŏ-pē)
Use of a fiberoptic endoscope to view the fetus and the fetal surface of the placenta transabdominally, and also for collection of fetal blood from the umbilical vein for prenatal diagnosis of fetal disorders.

fetoscopy

Visual examination of the fetus within the womb (uterus), by means of a fine fibre-optic viewing and illumination system passed into the amniotic fluid, through the wall of the uterus. Fetoscopy allows confirmation of physical abnormalities. There is a small risk of causing abortion.

Nathan, whose research in fetoscopy has resulted in prenatal diagnosis of sickle cell disease and Cooley's anemia, has urged that no research procedure be permitted which might damage the fetus, since such research could seriously affect a pregnant woman's decision about whether to proceed with the abortion.

Not only does the technology of fetoscopy seem to validate these long-standing images of the womb, so does - as Adams was surprised to discover - some twentieth-century speculative feminist fiction.
Adams links the modern physician, brandishing the supposedly revolutionary techniques of fetoscopy and ultrasound, with the ancient philosopher who helped the poor benighted soul out of the cave of illusion.
Invasive uterine procedures performed during pregnancy (Such as amniocentesis, cordocentesis, chorionic villus sampling, fetoscopy, and cervical circlage) can damage the membranes, causing them to leak, but these are rare causes of PPROM.
A wide array of techniques are now available for identifying fetal defects in early pregnancy, including amniocentesis, fetoscopy and ultrasound.
The most common cause for membrane rupture is iatrogenic either due to a procedure such as amniocentesis or fetal reduction or fetoscopy. Spontaneous septostomy has been reported more commonly in chorio-amnionitis causing weakening of the membrane, excessive fetal movement and polyhydramnios which causes excessive pressures on the dividing membrane.
In some rare instances, the equalization of liquor on both sides of the membrane has resulted in balance of blood flow in the vessels and continuation of the pregnancy (8) with favorable outcome similar to the principle of therapeutic amniotomy which was performed prior to the advent of laser fetoscopy. The other complications of SSDM include pseudo-monoamniotic pregnancy, amniotic band syndrome and preterm labor.
At a fast pace, innovations and technological advances brought us the fetal heart rate monitor, noninvasive ultrasound, embryoscopy and fetoscopy, and, more recently, methods to measure maternal biochemical analytes as a means to assess the developing infant's health.

The introduction of ultrasound and fetoscopy represented new frontiers; they provided significantly more precise information about fetal growth and well-being, as well as detection of major congenital malformations and metabolic problems.
