title: Superior mesenteric artery pseudoaneurysm after blunt abdominal trauma.
abstract: True aneurysms and pseudoaneurysms of the visceral arteries are uncommon. Visceral artery aneurysms (VAAs) represent 0.1-0.2% of all vascular aneurysms and were also found in 0.1% of autopsies. VAAs most commonly affect the splenic (60%), hepatic (20%), and superior mesenteric (9%) arteries. Mesenteric injury caused by blunt abdominal trauma is relatively rare. A 30-year-old man arrived at our trauma hospital and was found to have a traumatic pseudoaneurysm of the superior mesenteric artery (SMA) after a motor vehicle collision. To date, only 10 visceral arterial pseudoaneurysms have been reported in the literature. We present an 11th case of a pseudoaneurysm involving the SMA after blunt abdominal trauma.
