Prenatal ultrasonic diagnosis and outcome of fetal inferior vena cava malformation / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the clinical value of prenatal ultrasound in the diagnosis of inferior vena cava malformation.Methods The ultrasonographic features of 95 cases of fetal inferior vena cava malformation were retrospectively analyzed,and compared with autopsy or postpartum follow-up.Results Among the 95 cases of fetal inferior vena cava malformation,39 cases were confirmed by autopsy,56 cases were diagnosed by neonatal ultrasonography,5 cases were confirmed by angiography or operation.Among them,37 cases were interrupted inferior vena cava,37 cases were double inferior vena cava,21 cases were left inferior vena cava.Forty of the 95 cases were terminate pregnancy(due to intracardiac or extracardiac malformations)or neonatal deaths(42.1%),and 55 cases had good prognoses(57.9%).Conclusions Prenatal ultrasound has important clinical value in diagnosing of inferior vena cava malformation,clearing whether it is associated with other malformations and assessing fetal prognosis.
