Nearly 20% of spontaneously aborted fetuses with chromosomal errors have been shown to have a triploid karyotype. Such a fetus is rarely encountered during the course of an amniocentesis at midtrimester. Because amniotic fluid cell polyploidy is an occasional finding among normal fetuses at midtrimester, the following report illustrates the importance of gathering corroborative evidence of an affected fetus before arriving at a prenatal diagnosis.
已证实，近20%染色体异常的自然流产胎儿具有三倍体核型。在孕中期羊膜穿刺术过程中很少遇到这样的胎儿。由于羊水细胞多倍体在孕中期正常胎儿中是偶尔发现的情况，因此以下报告说明了在进行产前诊断之前收集受影响胎儿的确凿证据的重要性。
