Coil Embolization Using Balloon Neck Plasty for a Wide-necked Aneurysm of the Common Hepatic Artery Originating from the Superior Mesenteric Artery

Abstract

Visceral artery aneurysms are relatively rare. Most of them are incidentally found asymptomatic. We report a case of transcatheter coil embolization using balloon neck plasty for a wide-necked aneurysm of the common hepatic artery originating from the superior mesenteric artery. A 55-year-old-woman with the hepatitis B carrier was referred to our hospital due to a mass which was identified on abdominal ultrasonography. Computed tomography showed a wide-necked saccular aneurysm measuring 20 mm in diameter on the common hepatic artery which arose from the superior mesenteric artery. Coil embolization using balloon neck plasty was performed to prevent from coil protrusions and preserve the flow of parent artery. Postoperative magnetic resonance angiography showed the good patency of the common hepatic artery and no evidence of aneurysm sac flow.
