Organ: Abdominal aorta, kidneys

Description:

A segment of the abdominal aorta is seen. Almost the whole segment is covered by a huge thrombus. The thrombus is cut on the left side, revealing some lines.

The aorta bulges out to the left. The kidneys are smaller than normal.

Diagnosis: Abdominal aorta with aneurysm, large thrombus and atrophic kidneys

Causes:

  • Virchow’s triad
    • Hypercoagulability
    • Endothelial damage
    • Abnormal blood flow

Theory:

The lines of Zahn are alternating lines of fibrin (lighter) and RBCs (darker). The kidneys are atrophic because of stenosis of the renal arteries.

See theoretical topic 25.
