Portal blood supply of liver metastases.
Using Microfil technique, hepatic arteries and portal veins were injected in four human cadaver livers with metastases of different origin. Specimens were dissected under stereomicroscope and vessels supplying the tumor nodules were traced. In all cases, tumor vessels could be filled from the portal side; in three, the supplying portal branches were rather wide. The findings were correlated with histologic sections.
