However, an initial computed tomographic (CT) scan revealed a huge HAA (67-84 mm diameter), which displaced the common hepatic artery in an upwards direction and the gastroduodenal artery in a forwards direction (Fig. 1a-d).
HAA under operation. (a) bilateral proper hepatic arteries shown as (1), and (b) inside of the aneurysm after clump and incision, (2) common hepatic artery and (3) inlet of the aneurysm.

After the patient underwent laparotomy, a pulsatile and huge HAA was confirmed and narrow bilateral proper hepatic arteries were identified (Fig. 2a). The pulsation in the aneurysm disappeared where there was a cluster of the common and proper hepatic arteries (Fig. 2b). Inflow and backflow of blood to the aneurysm was confirmed (Fig. 2b).
CT scan on day 7 after aneurysm resection. Cholecystitis and hepatic infarction of medial segment of left hepatic lobe were confirmed.
