Midgut Volvulus Induced Extensive Bowel Infarction

Midgut volvulus, mostly occurs due to congenital midgut malrotation, has been reported as a rare but lethal complication of some acquired medical conditions, such as postoperative adhesion bands, tumors, and mesenteric cysts. It is a surgical emergency to cause extensive bowel ischemia resulted from torsion of superior mesenteric artery. Early diagnosis and intervention is the only manner to prevent extended bowel necrosis. Here, we report a case of midgut volvulus with typical computed tomography features—the whirl sign, the transposition of the superior mesenteric artery and vein, and the ischemic change of bowel supplied by superior mesenteric artery. Early operation prevented the fate of extended bowel resection.
