Zahn infarct
A Zahn infarct is a pseudo-infarction of the liver.
It consists of an area of congestion with parenchymal atrophy but no necrosis, and usually due to obstruction of a branch of the portal vein.
Pathophysiology[edit | edit source]
- Zahn infarcts are unique in that there is collateral congestion of liver sinusoids that do not include areas of anoxia seen in most infarcts.
- Portal vein congestion is commonly seen in Zahn infarcts upon necropsy.
- Fibrotic tissue may develop in the area of the infarct and it could be caused by an occlusive phlebitis in portal vein radicles.
- Non ischemic infarct of liver with lines of Zahn.
Eponym[edit | edit source]
The Zahn infarct is named for Friedrich Wilhelm Zahn.
