Prenatal ultrasound diagnosis of fetal radial ray abnormalities / 中华超声影像学杂志

ABSTRACT

Objective To investigate prenatal ultrasound diagnosis of radial ray abnormalities and its clinical value. Methods All the fetus that entered usual prenatal ultrasound diagnosis were scanned each limb using a systematic continuous sequence approach (SCSA) with Acuson Sequoia 512 and GE Logiq 400 equipments. All the artificial aborted fetal radius malformation also had ultrasound examination in a simulating intrauterine estate and /or X-ray examination. Results Correctly diagnosis was made in 13 cases fetal radial ray abnormalities by prenatal ultrasonography following SCSA through the scaning course. All the fetal radial ray abnormalities had radius absence(only one skeleton in the forearm) or radius dysplasia and characteristic radial club hand. Ray abnormalities can be classifyied into three types on ultrasonography: type Ⅰ, radius absence; type Ⅱ,radius part absence; type Ⅲ,radius dysplasia.Conclusions Mastering characteristic radial club hand and SCSA are the keys to diagnose fetal radial ray abnormalities by prenatal ultrasonography.
