Abstract
From January 1984 to October 1986, a total of 185 prenatal diagnostic procedures were performed, viz. 120 chorionic villus samplings, 42 fetal blood samplings, 12 skin biopsies and 11 tumor biopsies. All procedures were performed under continuous ultrasound guidance. The methods are described, and indications for each procedure and clinical outcome discussed. Preliminary results have shown that ultrasonically guided fetal tissue biopsy is feasible for prenatal diagnosis, but randomized trials are needed for evaluation of the risk/benefit ratio.
