本文对155例早孕妇女进行了经宫颈获取绒毛方法的研究,并对三种不同来源与直径的抽吸管效果进行了对比。临床实验研究证实在B超指示下取材的成功率较盲吸法高,可达99%。改进后的Ⅱ型吸管将钢丝固定在吸管外,操作时不用抽管芯,比进口管操作简便,取一次检材成功率可达85%,实验结果表明,胚胎着床在子宫后壁较易取材成功。孕期7～8周时,在B超指示下取材一次成功率最高,且取到的组织量也最多。20例孕妇在活取绒毛后观察了3～7天后行人流术。近期观察无一例发生流产和胚胎宫内死亡,证明了本操作的安全性。
In this paper, 155 cases of early pregnancy women underwent cervical acquisition of villus method, and three different sources and diameters of the suction tube were compared. Clinical experimental studies confirmed that the success rate of drawing material under the B-ultrasound is higher than the blind suction method, up to 99%. The improved type II straw fixed the wire outside the straw, the operation without pumping die, easier to operate than the inlet tube, take a successful detection rate up to 85%, the experimental results show that embryo implantation in the uterine wall easier Drawn successfully. Pregnancy 7 to 8 weeks, drawn under the B-ultrasound highest success rate, and to take the most amount of tissue. Twenty pregnant women underwent abortion after 3 to 7 days after living the villus. No recent case of abortion and intrauterine fetal deaths proved that the safety of this operation.
