Superior mesenteric artery occlusion and small bowel ischemia

Discussion:

Due to the non-specificity of the clinical presentation, acute superior mesenteric artery thrombosis can be a challenging diagnosis to make and requires a low index of suspicion. There is usually a background of cardiovascular risk factors, and embolism is more common than in-situ thrombosis. The affected small bowel is thin-walled but distended due to loss of muscle tone of the bowel wall. It is uncommon for surgical confirmation of the diagnosis as this condition carries a high mortality.
