Doppler Sonographic Evaluation of Hemodynamic Changes in Colorectal Liver Metastases Relative to Liver Size

Abstract

Our findings may support the hypothesis that a humoral mediator-induced portal venous flow reduction causes perfusion changes in liver metastases from colorectal disease. However, an additional intrinsic hepatic hemodynamic event should also be present. Doppler perfusion index measurements can provide additional information in the evaluation of patients with colorectal liver metastases.
