ABSTRACT
Objective To investigate the diagnostic value of prenatal ultrasound for fetal structural abnormalities.Methods The clinical data of 3 101 fetus with structural malformations, diagnosed by prenatal ultrasound and confi rmed after induced labor, and 856 cases of missed diagnosis were analyzed. All these data were collected in Maternal and Child Health Hospital of Tangshan City from January 2010 to June 2014. The types and number of fetal structural abnormalities were recorded. The rates of detection and missed diagnosis for the fetal structural abnormalities were calculated and the reasons for missed diagnosis were analyzed.ResultsA total of 3101 cases (4 171 positions) were diagnosed as fetal structural abnormalities by prenatal ultrasound. The detection rate was 11.51‰ (3 101/269 501). There were 856 cases (947 positions) of fetal structural abnormalities were missed, and the missed diagnosis rate was 3.18‰ (856/269 501). The incidence of fetal structural abmormalities was 14.68‰ (3 957/269 501). In terms of anatomy systems, the top five were cardiovascular system abnormalities (851 cases), the central nervous system abnormalities (691 cases), facial abnormalities (562 cases), urinary system abnormalities (476 cases), and respiratory system abnormalities (134 cases). In terms of single abnormalities, the top five were cleft lip and palate (549 cases), ventricular septal defect (519 cases), hydronephrosis (331 cases), spina bifi da (212 cases), and atrial-ventricular septal defect (163 cases). The top five of missed deformities were polydactylia/symphysodactylia (285 cases), ear deformities (108 cases), hypospadias (93 cases), foot abnormalities (92cases), and ventricular septal defect (52 cases).Conclusions There is a high detection rate for fetal structural abnormalities with prenatal ultrasound. Prenatal ultrasound is an indispensable means for the diagnosis of fetal malformation, but it also has some limitations. There is a high rate of missed diagnosis for polydactylia/symphysodactylia, microtia, and hypospadias.
