Microvasculature architecture of small liver metastases in man. A correlation between microfil vascular preparations and histologic sections.

The hepatic artery and the portal vein of 12 human cadaver livers with metastases of various sizes and origins were injected with Microfil. The microvascular appearances of the metastases were studied in order to receive an explanation to findings at angiography and contrast enhanced computed tomography. Histologic examinations were also performed of Microfil-injected specimens.
