Aneuploidy was mainly found in fetuses with increased NT thickness or and nasal bone hypoplasia, while P\/LP CNVs were mainly concentrated in fetuses with increased NT thickness or ventriculomegaly. The detection rate of karyotype was 5.7% (11\/193), the detection rate of aneuploidy plus P\/LP CNVs in fetuses with abnormal ultrasonic soft markers by CMA was 10.9% (21\/193), and the additional detection rate of CMA was 5.2%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CMA can significantly improve the detection rate of chromosomal abnormalities in fetuses with abnormal ultrasonic soft markers compared with karyotype analysis.
