Abstract
A 63-year-old man found in gastrointestinal endoscopy screening to have type 0 IIc early gastric cancer of the lower third of the stomach was also found to have a celiac artery aneurysm in abdominal CT staging. Abdominal angiography showed that the common hepatic artery, splenic artery, and left gastric artery branched from a celiac artery aneurysm 2 cm in diameter. We simultaneously conducted distal gastrectomy with Roux-Y reconstruction and aneurysmectomy with arterioarterial anastomosis of the common hepatic and splenic arteries. The celiac artery aneurysm was saccular with internal elastic lamina disruption, pathologically diagnosed as well-differentiated tubular adenocarcinoma, Type 0 IIc, T1 (M), N0, H0, P0, M0, Stage IA. Celiac artery aneurysms are quite rare and this is, to our knowledge, the first case of a celiac artery aneurysm simultaneously treated with aneurysmectomy and distal gastrectomy for gastric cancer in Japan.
