Ultrasound aspiration biopsy transducer amniocentesis.

Amniocentesis through an ultrasound aspiration biopsy transducer was performed 156 times. The technique is described and our results are presented. By closely monitoring the fetus and the needle entry into the amniotic cavity, we have avoided serious complications. The importance of adequate genetic counselling for the procedure is stressed, as most cases fall into the second trimester group, and the procedure is indicated in order to try to prevent inheritable disorders. The importance of continual monitoring of the fetus before, during and after the procedure is pointed out, and recommendations are made to avoid difficulties and complications in amniocentesis.
