Fetoscopy is an endoscopic procedure during pregnancy to allow access to the fetus, the amniotic cavity , the umbilical cord, and the fetal side of the placenta. A small (3-4mm) incision is made in the abdomen, and the endoscope is inserted through the wall of the abdomen and uterus into the amniotic cavity. Fetoscopy allows interventions such as a biopsy or laser occlusion of abnormal vessels.
