Prenatal ultrasound diagnosis of fetal intestinal volvulus and intussusception and misdiagnosis analysis / 中华超声影像学杂志

ABSTRACT

To investigate the characteristics of prenatal ultrasound sonography of fetal intestinal volvulus and intussusception , and analyze the misdiagnosis . Methods T he prenatal two‐dimensional and three‐dimensional sonographic features of 11 patients with volvulus and intussusception confirmed by prenatal ultrasound and/or postnatal confirmation from June 2017 to December 2018 were summarized and the prognosis were followed up . Results Of the 11 fetuses ,8 had intestinal volvulus and 3 had intussusception . Of the 8 cases of intestinal volvulus ,6 cases were correctly diagnosed by prenatal ultrasound ,and 2 cases were missed . Among the 6 cases diagnosed correctly ,3 cases showed a typical ＂vortex sign＂on the two‐dimensional sonogram . One case showed ＂coffee beans＂sign ,and 6 cases of three‐dimensional sonograms showed that the intestines were ＂coiled＂.＂Bread ring＂ sign appeared in 3 cases of intussusception ,and 1 case of intrauterine intestine was automatically reset . One of the 11 fetuses was induced to give birth ,1 was still in pregnancy ;9 cases were born and confirmed by surgery ,1 case died after operation . Conclusions Intestinal volvulus and intussusception have their characteristic sonographic features .When there is a short‐term fetal bowel dilatation with meconium peritonitis ,the existence of these two acute abdomen should be considered ,but w hen it is accompanied by intestinal necrosis ,typical signs of two‐dimensional sonograms are missing ,and three‐dimensional imaging aids in diagnosis .
