Definition / general
  • Vascular disorders affecting the liver can be systemic or localized and have intrinsic or extrinsic causes
  • Intrinsic causes:
  • Extrinsic disorders include heart failure, causing congestive hepatopathy
  • Normal liver is resistant to ischemia, due to dual blood inflow (hepatic artery and portal vein)
  • Cirrhosis also causes vascular remodeling, though it is not generally considered a vascular disorder (J Hepatol 2014;61:912)
Microscopic (histologic) description
  • Inflow abnormalities often cause ischemic necrosis
  • Outflow abnormalities often cause sinusoidal dilation
  • Most other histologic changes depend on the causative disease
