“…The common pathogenic factors in hepatic artery aneurysm are in the following order: atherosclerosis (32%), acquired medial degeneration (24%), trauma including iatrogenic causes (22%), and infection (10%) [2]. Less common causes are vasculitis including collagen diseases, such as polyarteritis nodosa or rheumatoid arteritis, biliary tract disease, pancreatitis, and liver abscess [3,[7][8][9][10].…”

“…Previously, nonruptured hepatic artery aneurysms were treated by surgical procedures, such as aneurysmectomy, ligation of the involved artery, and segmental resection of the involved liver [2,12]. However, arterial embolization and coil occlusion using transcatheter technique, and percutaneous thrombin injection have been replacing surgery [6,12,13].…”

“…Since the first report of a hepatic artery aneurysm by Wilson [1] in 1819, approximately 400 cases of this disease have been reported in the world literature [2][3][4]. Hepatic artery aneurysm is uncommon with an estimated incidence of less than 0.25% [2], which accounts for 20% of all splanchnic artery aneurysms, being the fourth in incidence following aorta, iliac, and splenic arteries of abdominal aneurysms [2][3][4].…”

As in other visceral aneurysms, the rupture of hepatic artery aneurysms is very high and potentially lethal [3][4][5].…”

An 18-year-old man developed a sudden onset of upper abdominal pain with vomiting. Ultrasound and computed tomographic (CT) scans revealed the spontaneous rupture of an intrahepatic artery aneurysm with subcapsular hematoma. A celiac arteriogram demonstrated a ruptured intrahepatic artery aneurysm in the right lobe of the liver, right extrahepatic artery aneurysm, obliteration of gastroduodenal artery, and abnormal flow pattern of the splenic artery. Portal vein phase, using superior mesenteric arteriography, showed portal vein varices and obliteration of the portal trunk. A right hepatic lobectomy was performed. The cut surface of the resected liver revealed a ruptured intrahepatic artery aneurysm with massive hematoma.

Splenic artery aneurysms are relatively common lesions that remain asymptomatic in the vast majority of patients. The commencement of symptoms is generally a morbid development because it frequently heralds either frank rupture or an erosive process that involves neighboring structures. Erosion into the splenic vein has been reported but is extremely rare. When this event occurs, the central arteriovenous fistula almost inevitably leads to a dramatic increase in portal venous pressures, which may subsequently be manifested as upper gastrointestinal tract hemorrhage. Herein, we report an unusual case of splenic artery aneurysm that was complicated by arteriovenous fistula formation in which high flow through the central splenic shunt led to the development of nontransmural small-bowel ischemia due to a mesenteric steal syndrome, which presented as acute lower gastrointestinal tract hemorrhage. Diagnostic modalities and therapeutic interventions used in this case are detailed, followed by a brief review of the pertinent literature.
