[Embolization of the hepatic artery in cases of atypical anatomical structural variants in patients with malignant liver tumors].
Therapeutic embolization of the hepatic artery was performed in 60 patients with nonresectable malignant liver tumors. Atypical topographical anatomical variants of the arterial system of the liver were revealed in 10 of them (16.7%). In 8 patients two hepatic vessels, one coming out of the celiac artery, the other--out of the upper mesenterial or left gastric artery supplied a tumor with blood. In three of them one vessel was embolized, in five patients both arteries were embolized. The blocking of the entire blood flow of a tumor brought about a positive clinical effect in all the patients. Embolization of one blood-supplying artery alone led to no improvement. A conclusion was made of a necessity to achieve arterial devascularization of the entire tumor tissue area during intravascular therapy.
