Splenic Artery Aneurysm of the Hepatosplenomesenteric Trunk

抄録

We herein report the case of a splenic artery aneurysm with a hepatosplenomesenteric trunk that presented in a pregnant woman. Catheter embolization was not performed due to the wide neck of the aneurysm and its close location to the trunk indicates a high risk of mesenteric trunk thrombosis. We instead performed surgical resection of the aneurysm after successful delivery of the infant by Caesarian section. The splenic artery was reconstructed by side-to-end anastomosis with the common hepatic artery.
