ABSTRACT

Prenatal 2D and 3D ultrasonographic examinations were performed for 67 008 pregnant women in Renmin Hospital of Wuhan University from January 2013 to December 2016.Among 69 013 fetuses,71 cases of congenital vertebral deformities were diagnosed with a detection rate of 0.103%.There were 40 cases of semi-vertebrae,23 cases of butterfly vertebrae,2 cases of coronal vertebral body fissure and 6 cases of vertebral fusion.Half vertebral deformity was the most common vertebral abnormality accounting for 56.3%(40/71),and the coronal vertebral body fissure was the least abnormality.Among 71 abnormal vertebral fetuses,there were 40 cases with other abnormalities,of which 28 fetuses were induced abortion, 12 fetuses were born;there were 31 cases of simple vertebral body anomalies,of which 8 fetuses were born and 23 fetuses were induced abortion.In infants with a single vertebral anomalies had no significant scoliosis,X-ray examination was performed 3-6 months after birth,the results were consistent with prenatal ultrasound diagnosis.Fifty one cases of induced abortion were examined by X-ray,the prenatal diagnosis was consistent with X-ray findings in 48 cases,and the remaining 3 cases were all multiple hemi-vertebrae with missed diagnosis of congenital butterfly vertebral deformity.
