Transvaginal chorionic villus sampling (CVS) using concurrent transabdominal ultrasound guidance was performed in 20 women who desired CVS but could not be offered transcervical or transabdominal approaches because of uterine position and placental location. Satisfactory amounts of chorionic villi were obtained in all 20 cases with no maternal discomfort, an occurrence that contrasts with our experience in transvaginal CVS using endovaginal ultrasound guidance. We believe that transvaginal CVS using concurrent transabdominal ultrasound guidance warrants consideration as an alternative technique for first-trimester CVS in selected patients.
对20名希望进行绒毛取样（CVS）但因子宫位置和胎盘位置无法采用经宫颈或经腹途径的女性，采用经腹超声同步引导进行经阴道绒毛取样。20例均获得了满意量的绒毛，且产妇无不适，这一情况与我们使用经阴道超声引导进行经阴道绒毛取样的经验不同。我们认为，对于特定患者，采用经腹超声同步引导的经阴道绒毛取样值得作为孕早期绒毛取样的替代技术加以考虑。
