The solitary hyperdynamic pulsating superior mesenteric artery: an additional dynamic sonographic feature of midgut volvulus.

Midgut malrotation complicated by volvulus is a surgical emergency. The diagnosis is often suspected clinically and usually confirmed by barium meal. In this case the diagnosis of malrotation with midgut volvulus is made by ultrasound. We describe the solitary hyperdynamic pulsating superior mesenteric artery as an additional dynamic sonographic feature of midgut volvulus.
