and sonography have been employed recently to detect neural tube defects, including such serious structural abnormalities as anencephaly (the absence or near-absence of a cranial vault and cerebral hemispheres of the brain) and myelomeningocele (hernia of the spinal cord and surrounding membranes through a defect in the vertebral canal).
Ezra Davidson tests the new prenatal diagnostic tool known as the fetoscope on low-income black and Hispanic women in South Central Los Angeles just before they have abortions, to see how often fetoscopy
itself causes an abortion.
Now the technologies of fetoscopy
and ultrasound allow us to go to the other extreme, making it possible to erase the mother entirely, with, Adams maintains, profound implications for the practice and ethics of obstetrics.
On the other hand, they have had experience with more recent medical advances: sonograms and fetoscopy
, fetal surgery, and the rescuing of ever-younger preemies.
Quintero and his colleagues performed the procedure, called operative fetoscopy
, to tie a knot in the umbilical cord of an 18-week-old fetus that lacked a brain and heart and jeopardized the life of its healthy twin, they write in the Feb.
One can get a close detail before the delivery through fetoscopy
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.
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.
A wide array of techniques are now available for identifying fetal defects in early pregnancy, including amniocentesis, fetoscopy
Instrument Detects and Treats Twin to Twin Transfusion Syndrome--USA
The most common cause for membrane rupture is iatrogenic either due to a procedure such as amniocentesis or fetal reduction or fetoscopy
Brief report: umbilical-cord ligation of an acardiac twin by fetoscopy
at 19 weeks of gestation.
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.
assistant professor of OB-GYN at USC and Director of Fetal Therapy and Minimally Invasive Fetal Surgery at CHA Hollywood Presbyterian Medical Center, performs operative fetoscopy
and other innovative fetal surgical procedures.
