title: Midgut volvulus causing fetal demise in utero.
abstract: Intestinal malrotation has an incidence of 1 per 6000 live births. The most serious consequence of malrotation is volvulus. Midgut volvulus is a rare condition in which the small bowel and proximal colon twist around the superior mesenteric artery, leading to a high-grade proximal bowel obstruction and vascular compromise of the intestine, thereby leading to infarction of the involved intestine. Midgut volvulus rarely occurs antenatally and is usually not lethal in utero. There are only 7 cases of intrauterine fetal demise caused by midgut volvulus reported in the literature. We report a case of intrauterine fetal demise at 38 weeks of gestation, due to cardiovascular failure and shock from midgut volvulus. Non-specific abnormalities, including ascites and dilated bowel, had been seen on the antenatal ultrasound from the 15th week of gestation. In addition to the volvulus, the fetus had intestinal atresia and arthrogryposis.
