The technique of transcervical chorion biopsy was evaluated in women about to undergo therapeutic termination of pregnancy. The trophoblast biopsy catheter (Portex) under real-time ultrasound guidance was the most reliable in obtaining chorionic villi. The overall success rate for chorion biopsy was 73% in the first 100 patients studied.
对即将接受治疗性终止妊娠的女性进行了经宫颈绒毛膜活检技术的评估。在实时超声引导下的滋养层活检导管（波特克斯）在获取绒毛方面最为可靠。在最初研究的100例患者中，绒毛膜活检的总体成功率为73%。
