A 70-year-old man with a ruptured aneurysm located at the right middle cerebral artery underwent neck clipping three days after the onset of a subarachnoid hemorrhage. Four days later, the patient suddenly went into a shock state due to intra-abdominal bleeding. Angiography showed a ruptured hepatic artery aneurysm that was embolized using the coil-through endovascular technique. The subsequent postoperative course was uneventful. The present case suggests that an incidental visceral artery aneurysm may rupture during therapy for cerebral vasospasm following a subarachnoid hemorrhage.
