지속임신에서 시행한 경복식 융모막채취법 = Transabdominal Chorionic Villus Sampling in Continuing Pregnancies

다국어 초록 (Multilingual Abstract)

Transabdominal chorionic villus sampling(TA-CVS) has been carried out in twenty-four pregnant women at Kyung Hee University Hospital from April, 1990 to January, 1991. We present here our technique and clinical experience with TA-CVS. We have performed TA-CVS using a single aspiration needle under the freehand ultrasound guidance. Twenty-four pregnant women underwent TA-CVS between 10 and 18 weeks of gestation. Sampling was usually carried out at the tenth or eleventh weeks of gestation. TA-CVS was successful in 22 of 24 pregnant women, a success rate of 91.7%. The amount of chorionic villi obtained by TA-CVS was 10.2 6.9 mg and sufficient chorionic villi( 5 mg) were obtained from 15(68.2%) of the 22 successful TA-CVS cases. The mean number of needle insertion was 1.3 0.4 and in 77.3%(17/22) of the successful sampling only a single needle passage was required. To date, no fetal loss was observed in this TA-CVS program. We conclude that TA-CVS is a potentially useful technique in case of unfavorable anatomic and clinical conditions for safe transcervical chorionic villus sampling.
