title: [Sampling of the chorionic villi: transcervical fine-needle and endoscopic aspiration].
abstract: In 63 cases chorionic villi sampling has been performed under complete anesthesia just before legal abortion; nine of them were endoscopic transcervical and 54 transcervical by means of a catheter under direct ultrasonic control. 81% offered useful chorionic villi, 17.4% only decidual material. The last 21 aspirations by means of a catheter between the 8th and the 12th week of gestation (p.m.) caused no problem at all. From the first punction on useful chorionic material has been obtained.
