Hepatic artery aneurysm
Citation, DOI & article data
Hepatic artery aneurysms are a type of visceral arterial aneurysm.
They are rare representing about 0.01-2% of all arterial aneurysms but are considered the second most common aneurysm of the splanchnic system after splenic artery aneurysms. They may account for 20% of all visceral aneurysms.
They may occur in the intra-hepatic or extra-hepatic portions of the hepatic artery.
A rupture of hepatic artery aneurysms can be seen in more than 80% of patients with mortality rates approaching 40% with surgical treatment. Management options could range from prosthetic graft reconstruction to excision to embolization. Some suggest surgery being more appropriate for extrahepatic aneurysms with radiological embolization more appropriate for intrahepatic aneurysms.
