“…there have been several reports of small-bowel volvulus that occurred prenatally, [11][12][13][14][15][16][17][18] in which different fetal sonographic findings were shown. However, a definitive diagnosis was made postnatally with exploratory laparotomy.…”

olvulus is generally a condition that occurs in the pediatric age group, commonly associated with intestinal malrotation. The intrauterine occurrence of this condition is a rare occasion, and only a few cases have been reported. Precise diagnosis is hampered by the extensive differential diagnoses of fetal intra-abdominal masses observed during sonographic examination. However, detection of the "whirlpool sign" facilitates sonographic diagnosis of this condition. We report a case of intestinal volvulus that occurred in utero diagnosed definitively with 2-dimensional and 3-dimensional (3D) Doppler sonography. To our knowledge, there is no previous report of such a case that was diagnosed by 3D Doppler sonography in the English literature. Case ReportA 50-year-old nulliparous woman was admitted to our maternity ward at 28 gestational weeks after decreased fetal movements. Her pregnancy was achieved with ovum donation and in vitro fertilization. She had 1 previous pregnancy that ended with a spontaneous miscarriage. Her medical history was unremarkable. Her routine follow-up results were normal during this pregnancy, including a fetal anatomic scan that was performed 3 weeks earlier.Initial evaluation revealed a nonstress test result of a reassuring fetal heart rate pattern and no uterine contractions. On fetal sonography, a singleton fetus was observed with a normal amniotic fluid index and no ascites or intraperitoneal echogenicity. However, a dilated stomach was seen, together with a fixed, dilated, Cshaped bowel loop in the upper part of the abdominal cavity (Figure 1). The affected bowel had a thick echogenic

“…6,43 The radiologic findings of prenatal volvulus are usually non-specific like free peritoneal liquid and dilated loops that can be hypointense in T2 in cases of hemorrhagic necrosis. 43,44 The intestinal content passing through the peritoneal cavity can create one pseudo-cyst, and originate one fibroadhesive peritonitis with calcifications or intestinal atresia seen at birth only. Some cases of syndrome of short intestine can be secondary to intrauterine volvuli with reabsorption of the infarcted loop and self-anastomosis of all those loops feasible to reestablish intestinal transit.…”

“…Fetal magnetic resonance imaging could help in the diagnosis [3,9] . The whirlpool sign is the definitive sonographic sign of midgut volvulus secondary to malrotation and is produced by the bowel loop and its accompanying mesentery and mesenteric vessels that wrap around the main superior mesenteric artery.…”

Intrauterine Intestinal Obstruction due to Fetal Midgut Volvulus: A Report of Two Cases

et al. 2006

View full text Add to dashboard Cite

Fetal midgut volvulus is quite rare, and few surviving infants – particularly cases with meconium peritonitis – have been reported in the literature. We report two cases of intrauterine intestinal obstruction due to fetal midgut volvulus associated with intestinal malrotation. In both cases, the infant survived after cesarean section delivery and appropriate surgical intervention, and they both continue to be in good overall condition. We discuss the prenatal signs and outcome of in utero intestinal volvulus. Close prenatal follow-up and appropriate timing of delivery in cases where ultrasound examination shows signs of fetal intestinal obstruction, as well as optimal postnatal treatment, are essential to reduce the morbidity and mortality associated with fetal midgut volvulus.
