妊娠早期取绒毛组织作胎儿遗传病的诊断已成为预防遗传病对策的一个重要部分。临床主要应用两种采集标本的方法,即经宫颈和经腹壁,以及几种技术和器械。有些作者认为经腹壁吸出绒毛组织要比经宫颈的技术更安全和实用。本文对1159例经腹壁取了绒毛标本。 The diagnosis of fetal genetic disease during early pregnancy using aspiration of the fetus has become an important part of the strategy to prevent genetic diseases. The main clinical application of two methods of collecting specimens through the cervix and the abdominal wall, and several techniques and instruments. Some authors believe that aspiration of villous tissue through the abdominal wall is safer and more practical than transcervical techniques. In this paper, 1159 cases of the villi were taken from the abdominal wall.
