Abstract
Visceral artery aneurysms are rare with an incidence of 0.1%-0.2%. Of these, 20% are hepatic artery aneurysms (HAAs). Despite the potential of remaining asymptomatic for long periods of time, the risk of rupture for HAAs is 20%-80%. Treatment includes operative management with open or endovascular techniques. HAA in the setting of pancreatitis has been reported in two prior cases outside of the United States. However, there have been no cases describing the association of HAA and giant cell arteritis (GCA). We present a rare case of an 80-year-old male with a history of GCA who was found to have developed HAA following an episode of acute pancreatitis that was repaired surgically with an open technique. To our knowledge, the association between HAA with acute pancreatitis and GCA has not been reported before.

Summary
Visceral artery aneurysms are rare, with an incidence of 0.1%-0.2% [1]. Hepatic artery aneurysms (HAAs) were first described by Wilson in 1809 [2] and represent 20% of all visceral aneurysms [1]. We present the case of an 80-year-old male with a history of GCA who was found to have developed an HAA following an episode of acute pancreatitis that was repaired surgically with an open technique. How to cite this article Ohanisian L, Rubay D, Morrow M L, et al (August 17, 2019) Hepatic Artery Aneurysm in the Setting of Acute Pancreatitis and Giant Cell Arteritis. The celiac artery and splenic artery did not appear aneurysmal, and the left gastric artery appeared to come off the splenic artery distal to the origin of the aneurysmal common hepatic artery. Due to the distal reconstitution of retrograde flow into the GDA from the SMA, and left gastric artery coming off of the splenic artery distal to the origin of the aneurysmal common hepatic artery, the patient was taken to the operating room for open HAA repair. Arterial blood flow through the splenic, left gastric, and both left and right hepatic arteries was confirmed using intraoperative Doppler
