Abstract
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.
