Isolated injury to mesenteric vessels in blunt trauma is uncommon. Most patients with these injuries present with abdominal pain, shock, or laboratory evidence of bowel and/or liver ischemia. We report herein the case of a man with asymptomatic isolated celiac artery dissection after blunt trauma suspected by screening abdominal computed tomography and confirmed by catheter-based angiography. The patient was treated with 3 months of oral anticoagulation alone.
