Single-Operator Aspiration of Chorionic Villi Using an Ultrasound-Guided Silver Cannula
After several years of multicentre evaluation, the early expectations for biopsy of chorionic villi are being realised. Increased world experience (L. Jackson, personal communication 1984) suggests that chorionic villi sampling (CVS) is a viable and successful method of first trimester prenatal diagnosis. Although further evaluation is awaited, the risks associated with the procedure appear small. To realise the full potential, however, the CVS technique must be simple, successful and safe.
