title: "Streaming" in portal vein. Its effect on the spread of metastases to the liver.
abstract: Fifty-five consecutive patients with colorectal carcinoma and hepatic metastases on the Tc-99m sulfur colloid liver/spleen scan (TSC) were evaluated to see if the pattern of spread of colorectal metastases was affected by the venous drainage of the primary site. The results suggest that significant streaming probably exists in the portal vein and the spread of metastases to the liver is affected by it. This information has a potential clinical implication in terms of diagnostic workup and chemotherapeutic infusions. It also supports the speculation that a streaming effect exists in humans.
