Objectives Segmental arterial mediolysis is a rare disease that most commonly affects the superior mesenteric artery among abdominal arteries. However, aneurysms involving the ileocolic arterial branch of the superior mesenteric artery are extremely rare. Here, we describe the treatment of a patient with an ileocolic arterial aneurysm suspected to have occurred secondary to segmental arterial mediolysis. Methods We confirmed the diagnosis of ileocolic arterial aneurysm, which showed the characteristic “string-of-beads” appearance of the distal main trunk of the superior mesenteric artery on angiography. We performed endovascular coil embolization for the aneurysm, and for both the inflow and outflow vessels. After confirming that the aneurysm was no longer visible, the treatment was completed. Results There were no clinical findings suspicious of ischemic enteritis or intestinal necrosis after embolization. We confirmed that the ileocolic arterial aneurysm was not observed on computed tomography angiography one month after treatment. Conclusions While development of an ileocolic arterial aneurysm associated with segmental arterial mediolysis is very rare, it is at a high risk of sudden rupture. Therefore, coil embolization is a useful intervention in such patients and can be implemented based on the size and morphology of the aneurysm.

Artery Branch

Superior mesenteric artery and pancreaticoduodenal artery aneurysms are rare. Agenesis of the celiac axis has only been reported four times. The reported etiologies of superior mesenteric artery and branch artery aneurysms include infection, atherosclerosis, inflammatory processes such as pancreatitis, dissection, collagen vascular disorders, polyarteritis nodosa, and trauma. We report an aneurysm of the superior mesenteric artery (SMA) branch, the inferior pancreaticoduodenal artery, arising in a patient with congenital absence of the celiac trunk. The patient presented with intermittent left upper quadrant pain without weight loss or change in bowel habits. The aneurysm was identified on abdominal computed tomography scan with angiographic confirmation of the aberrant anatomy. The patient was treated by aneurysmectomy and pancreaticoduodenal artery reconstruction with an interposition vein graft from the SMA. The patient recovered without complications and is asymptomatic with a patent vein graft 2 years after operation.
