1. Spontaneous visceral artery dissection is an uncommon cause of abdominal pain that may involve the celiac trunk, superior mesenteric, renal, and inferior mesenteric arteries.  Extension into more distal branches is also common.   2. Because the diagnosis is rarely suspected initially, visceral artery dissection is often suggested from subtle findings on portal venous phase CT.  Subsequent CT angiography confirms dissection and better characterizes the extent of vascular involvement. 3. The management of spontaneous visceral artery dissection is determined by the organ involved and extent of distal malperfusion.     

1. Overview of spontaneous visceral artery dissection a. Clinical presentation b. Etiologies of spontaneous visceral artery dissection. c. Association with inherited connective tissue diseases. 2. Discuss imaging work-up, CTA protocol, and pertinent findings. 3. Quality images of visceral artery dissection evaluated with 64-slice CT and 3D reconstructions:  examples include the celiac axis, superior mesenteric, renal, common hepatic, and splenic arteries. 4. Complications of distal malperfusion.  5. Treatment and recommendations for follow up imaging and multi-disciplinary care.
