Previous reports have suggested that the fetal loss rate with transcervical chorionic villus sampling was high in the initial 100-300 procedures performed. In a consecutive series of 155 patients with first-trimester transabdominal chorionic villus sampling (CVS), we observed a total fetal loss rate of 8.4%, and loss rate not attributable to induced abortion or cytogenetic abnormality of 3.2%. Our results demonstrate that transabdominal CVS in the first trimester of pregnancy is a safe method of prenatal diagnosis.
先前的报告表明，在最初进行的100 - 300例经宫颈绒毛取样术中，胎儿丢失率较高。在连续的155例孕早期经腹绒毛取样（CVS）患者中，我们观察到总的胎儿丢失率为8.4%，不归因于人工流产或细胞遗传学异常的丢失率为3.2%。我们的结果表明，孕早期经腹CVS是一种安全的产前诊断方法。
