BACKGROUND: Celiac artery aneurysm is very rare, and even is more uncommon in patients with celiacomesenteric trunks. With recent developments in diagnostic imaging, the detection of asymptomatic abdominal visceral aneurysms has increased. However, some abdominal visceral aneurysms are still first discovered after a rupture. An abdominal visceral aneurysm rupture can occur suddenly and lead to shock due to intraperitoneal hemorrhage. Two cases of celiac artery aneurysms that involved common celiacomesenteric trunks are presented.
CASE REPORT: Case 1 was a 63-year-old man who was referred to our facility for further study after a routine abdominal ultrasound identified an aneurysm in the superior mesenteric artery. Contrast-enhanced computed tomography (CT) scan revealed a 39-mm aneurysm in the celiacomesenteric trunk and its branches. Case 2 was a 32-year-old man who was referred to our facility after an abdominal ultrasound performed during a physical examination revealed a celiac artery aneurysm.
Contrast-enhanced CT revealed a 31-mm aneurysm in the celiacomesenteric trunk and its branches. In both patients, the aneurysms were proximally located, and the distinctive anatomy of the celiacomesenteric trunk made endovascular treatment difficult. Open replacement and reconstructive surgery was performed to repair the aneurysms with grafts from the great saphenous vein. Both patients had uneventful postoperative courses.
CONCLUSIONS: The optimal treatment for the patients described was open surgical repair because the lower risk of occlusion of the visceral branch made it safer and more reliable than an endovascular approach.
