Abstract:
Objective To review the clinical treatment and outcome of ultrasonographic soft markers in prenatal diagnostics. Methods This study recruited 268 pregnant women who underwent prenatal diagnostics in our hospital between Jun 2005 to Mar 2009. Fetuses were followed up postnatally. The outcome and chromosomal abnormalities of ultrasonographic soft markers were assessed. Results Of 268 cases consulted, 29 cases were missed (10.8%), 34 cases (12.7%) chose abortion, and 205 cases (76.5%) delivered. The top four most common delivered isolated markers were thickened nuchal fold, mild pyelectasis, echogenic bowel and rhizomelic limb shortening. Mild ventriculomegals had the highest aborted rate (17.2%). Six chromosomal structural abnormalities and one 21-trisome were detected in 59 fetuses who received chromosomal examination. Conclusions Ultrasonographic soft markers are risks to both fetal trisome and chromosomal structural abnormalities. Owing to extinction in most cases, consultant should be strengthed to avoid unnecessary invasive examination and abortion.
