Application of continuous sequential ultrasound and three-dimensional surface imaging in the screeningon fetal limb deformity
Objective To investigate the application value of continuous sequential ultrasound and three-dimensional surface imaging in the screening of fetal limb deformity.Methods 1 176 pregnant women with gestation for 16~34 weeks from Nov.2014~Mar.2017,and continuous sequential ultrasound was performed for limbs,and three dimensional surface imaging was performed for suspected limb deformities.The development of fetal limb was observed, and the results were compared with the results of invasive chromosome examination and labor induction.Results 37 cases were detected by ultrasound with limb malformations in 1 176 cases, accounting for 315%,and 26 cases were accompanied with other structural abnormalities, accounting for 70.27%,The highest detection rate was 18~24 weeks, accounting for 89.19%,37 cases were induced labor, compared with the gross specimens and radiation, prenatal ultrasound coincidence rate was 100%,8 cases were bnormal karyotypes, accounting for 24.14%.Conclusions Continuous sequential ultrasound detection combined with three-dimensional surface imaging is a good method for screening fetal limb deformities.
