[Biopsy of the chorionic villi with the aid of ultrasound in the diagnosis of chromosome disorders in the 1st trimester].
Chorion frondosum biopsy is a method of antenatal diagnosis based on the chorion villi cell analysis, with the aim of detecting hereditary disorders of chromosomal and genetic origin. The method was applied at the Department of Gynaecology and Obstetrics in women with undesired pregnancy from 8 to 12 weeks. This was the first phase of our investigation. Chorion frondosum samples were taken by Jackson's forceps and "Portex" cannula for transcervical aspiration. The role of ultrasound, as a component part of this method, is pointed out in the paper. Ultrasound was applied in a way not to damage the embryo and its membranes, and to locate chorion frondosum--the site of taking the appropriate chorionic villi. The success of detection of foetal chromosomal constitution in our study was 84%. Chromosomopathy was registered in on case. The foetus had tetraploidy--92, XXYY.
