[Possibilities and limitations of fetoscopy in prenatal diagnosis]

The need for fetoscopy in prenatal diagnosis has been established and its value has been demonstrated. The number of cases for which this fetoscopy is necessary remains small. The less traumatic ultra-sound diagnosis more and more competes with endofetoscopic inspection. The fetoscopy is necessary for fetal tissue biopsy and fetal blood sampling. Progress in intra-uterine treatment can be expected.
