Abstract:
Objective To determine the diagnostic value of two and three dimensional ultrasound in detecting fetal hand malformations. Methods In the retrospectively analysis,the severe fetal hand malformations detected by prenatal ultrasound during the recent three years in our hospital were classified according to the prenatal sonographic characteristics,family history,karyotype analysis and autopsy results,etc.Results Fourteen fetuses with hand-anomaly were detected during the 16-28th week of gestation,both hands were affected in 10 cases,with the same morphology bilaterally in 8 cases.Thirteen cases had other abnormal sonographic findings.They were detected and classified into three categories,Wrist deformity (9 cases),three fetuses were associated with total absence of radius and radial clubhand,and six fetuses had palmar deviated hands,with various etiologies including familial hereditary arthrogryposis multiplex congenita,distal type 1 (AMCD1),amniotic band syndrome,body stalk anomaly,trisomy18 and micromelia.Hand (figer) hypoplasia or aphasia (3 cases),one hand was absent in one fetus without associated anomaly,absence of five fingers with ipsilateral multicystic dysplastic kidney in the second fetus,and the third fetus had split hand/foot malformation (SHFM).Overlapping fingers (4 cases),three of them were trisomy18,and two fetuses had both wrist deformity and overlapping fingers.Conclusions Prenatal two and three dimensional ultrasound play an important role in detecting and diagnosing severe type of fetal hand malformations.
