A Surgical Case of a Huge Splenic Artery Aneurysm with a Celiac Artery Aneurysm

Abstract

A 61-year-old man had epigastric pain. Abdominal computed tomography and digital subtraction angiography revealed a celiac artery aneurysm (20 mm) and splenic artery aneurysm (85 mm) but without any evidence of rupture. We performed resection of the spleen and splenic artery aneurysm, and ligation of the celiac and splenic artery, and simultaneously, infrarenal abdominal aorto-common hepatic artery bypass using an externally supported 6 mm ePTFE graft to maintain the hepatic blood supply. The ePTFE graft was covered with the omentum to prevent pseudoaneurysm and graft infection. The patient had a pancreatic fistula postoperatively but there was no direct contact with the graft, and he left the hospital without occurrence of a pseudoaneurysm or graft infection.
