Abstract Three cases of chronic volvulus of the small bowel in midgut malrotation are presented, all of whom manifested similar angiographic findings: proximal occlusion of the superior mesenteric artery and vein and development of collateral vessels. These findings may indicate the pathophysiology of chronic volvulus in midgut malrotation; the volvulus is progressive and eventually results in the twisting of the mesenteric root itself, but because of its chronic nature collateral circulation develops, eliminating bowel necrosis. Computed tomography (CT), performed in two cases, revealed dilated, tortuous vessels in the mesentery in addition to the known CT finding of a whirl-like pattern of the volvulated small bowel loops. Sonography, performed in one case, showed an unique feature of whirling sonolucent layers probably representing the volvulated small bowel loops intermixed with dilated mesenteric collateral vessels. We would like to emphasize the usefulness of CT and sonography in the early diagnosis of those cases with vague and nonspecific clinical manifestations.
