[Doppler examination of portal venous flow in liver neoplasms]

An attempt was made to measure blood flow of portal system at various stages of neoplastic changes in the liver, which could be of some prognostic and therapeutic value. In the group of 80 studied persons, 20 patients had hepatic angioma, 6 patients hepatic cancer, 24 patients metastatic cancer affecting to the liver. Control group consisted of 50 healthy volunteers. No disturbances of blood flow in portal system in the group of patients with hepatic angioma were found. In the group with primary hepatic cancer decrease of TAV and TF in portal and splenic veins were noted, especially in 2 cases with numerous changes with relatively big sum of diameters, as compared with control method. In group with metastases of cancer to the liver slight decrease of blood flow in portal and splenic veins was observed as compared to the control group. Decrease in blood flow in the portal system was seen in cases with numerous and relatively big neoplastic focuses in the liver. Blood flow monitoring might be helpful in evaluation of the progress or regression of infiltrative changes in the liver.
