随着孕早期产前诊断日益广泛开展,利用绒毛与材料制备染色体,可以在孕早期作出诊断,比多年来国内外在妊娠中期(16—20周)羊水培养的诊断方法提前了10周左右,且迅速、简易、准确,便于孕早期淘汰异常胚胎,可即时行人工流产术。要获得满意的绒毛是做好这一工作的前提,因此如何取到适量的绒毛组织能满足制备染色体标本的需要,又不影响胚胎的继续发育这是一个关键问题。各地取绒毛的方法报导甚多,我院妇产科于1985年9月8日至10月19日在“B”超监测下及盲吸抽取早孕绒毛42例,现介绍如下:
With the widespread prenatal diagnosis of early pregnancy, the use of chorionic villi and materials preparation of chromosomes can be diagnosed in the first trimester, over the years at home and abroad in the second trimester (16-20 weeks) diagnosis of amniotic fluid in advance about 10 weeks, And rapid, simple, accurate, easy to eliminate abnormal embryos in early pregnancy can be artificial abortion immediately. To obtain satisfactory hair is the prerequisite for this work, so how to get the right amount of hair tissue to meet the needs of preparation of chromosome specimens without affecting the continued development of the embryo is a key issue. There are many reports of the method of taking down the hair, obstetrics and Gynecology in our hospital from September 8, 1985 to October 19, under the “B” super monitoring and blind suction pumping 42 cases of early pregnancy villi are as follows:
