Abstract:
90 without intestinal canal whirl sign was used as the diagnostic standard for whirl sign.Two experienced physicians evaluated the mesenteric vessel whirl sign and its morphological characteristics(including its site,rotation direction,rotation angle,distance between the start and end points of rotating vessels,and rotation radius) and associated signs.The difference in characteristics of whirl sign was compared between volvulus and non-volvulus patients.Results Mesenteric vessel whirl sign was found in 72 out of the 626 patients,including 64(10.4% ) in volvulus group and 8(88.9% ) in non-volvulus group.Mesenteric vessel whirl sign was complicated by intestinal canal whirl sign in 8 volvulus patients,complicated by superior mesenteric artery stricture in 6 volvulus patients.Mesenteric vessel whirl sign complicated by intestinal canal whirl sign was observed in only 2 non-volvulus patients with no superior mesenteric artery stricture.A difference in rotation angle and the start and end points of rotating vessels was found between the two groups(P
