True aneurysms of the pancreatoduodenal arteries are frequently associated with stenosis or occlusion of the celiac trunk caused by median arcuate ligament compression. Celiac stenosis cannot be cured, even by transarterial embolization, which has recently become a good alternative to open surgical repair. To prevent recurrence, management of median arcuate ligament compression to correct hemodynamics in vascular networks should also be performed. Herein we report a case of pancreatoduodenal arterial aneurysm with median arcuate ligament compression that was successfully treated with minimally invasive laparoscopic median arcuate ligament section. The patient was discharged 4 days after surgery with no complications. Enhanced CT 1 month after surgery revealed no residual celiac trunk stenosis or aneurysm. Normalization of blood flow by laparoscopic median arcuate ligament section is a good option for some patients with a pancreatoduodenal arterial aneurysm.
