Abstract
OBJECTIVE/BACKGROUND: Huge aneurysm of the visceral artery is rare and a treatment strategy for such cases has not yet been established. Here, we report a case of huge aneurysm of the common hepatic artery (44-mm diameter) successfully treated by stent placement. METHODS: A 77-year-old female patient was referred to our department due to growth of the common hepatic artery aneurysm. The cause of the aneurysm was suspected to be segmental arterial mediolysis. Due to the possibility of a spontaneous rupture, we decided to stent the common hepatic artery. RESULT: We had some difficulties during the procedure, such as thrombosis of the stent, and it was necessary to insert an additional stent. The procedure was effective and the patient has been doing well without any complications at the 6-year follow-up. CONCLUSION: Stenting is possible and effective in cases of huge aneurysm of the common hepatic artery.
