- Incidence
- 20% of splanchnic artery aneurysms
- M > F 2:1
- Most extrahepatic are true, intrahepatic false
- Clinical
- Rupture (≈ 20%) → 35% Mortality rate
- May occur into the biliary tree (producing haemobilia) or free intraperitoneal
- Sx triad (present in 1/3 of pts): Intermittent abdo pain, GI bleeding, jaundice
- Management
- If common hepatic artery involved → Can ligate because of collateral flow through the GDA
- Aneurysms in other portions of the artery usually require vascular reconstruction
