ABSTRACT: This case report describes the radiographic and ultrasonographic findings of three surgically confirmed cases of mesenteric volvulus or intestinal torsion in dogs. In all three cases, ultrasonographic findings included segmental ileus and absent or markedly reduced peristalsis of the affected small intestine, and partial loss of wall layering with increased overall echogenicity of the intestinal wall, but with normal to mildly increased wall thickening. No blood flow was detected in the affected small intestinal wall when assessed with colour Doppler. A moderate amount of peritoneal effusion was also detected with hyperechoic omental and mesenteric fat tissue throughout the peritoneal cavity. Few reports describe ultrasonographic findings of small intestinal ischemia in small animals. In all three cases presented here, ultrasound was helpful in demonstrating typical intestinal wall changes and helped to obtain the correct diagnosis of ischemic disease of the small intestine.
