Spontaneous Isolated Dissection of the Celiac Artery and Superior Mesenteric Artery: A Case Report

Simultaneous occurrence of spontaneous isolated dissection of the celiac artery (CA) and superior mesenteric artery (SMA) is rare. Here, we report the clinical course of a 50-year-old man who presented with severe, acute upper abdominal pain. Computed tomographic angiography (CTA) revealed segmental small intestinal ischemia and dissection of the CA and SMA. The patient was discharged after conservative treatment, but mild abdominal pain recurred subsequently. Several repeated CTAs showed small bowel wall thickening. These findings show that symptoms of SMA dissection along with intestinal ischemia can be alleviated with conservative treatment, but abdominal pain and chronic bowel wall thickening can persist for a long time.
