[Dependence of the therapeutic effect of hepatic artery embolization on the completeness of devascularization of liver tumor].

Of the 25 patients with malignant non-resectable tumors of the liver, the interruption of arterial blood supply of a whole neoplasm was achieved according to the findings of control angiography in 18. Objective signs of the improvement of the state were noted in 11 of them. The life time after embolization in 8 patients was in average (17.6 +/- 3.4) mos. Reduction of the arterial blood flow in the tumor, or occlusion of the right hepatic artery in involvement of the two lobes, was noted in 7 patients. The objective improvement of the state was noted in 1 of them, 4 survived in average (5.4 +/- 2.3) mos after embolization.
