In the paper anatomic and radiological preconditions are considered for intravascular treatment of hemangiomas of the liver based on the study blood vessels of corrosion preparations of 5 tumors, removed during a resection of a liver; results of 69 angiographies of the liver and 73 hepatic radiographies. The authors offer a 3-marks evaluation of the arterial blood flow in a total blood supply of the hemangiomas. Study of the versions of the arterial blood supply for hemangiomas enabled to validate the different approach in use of intravascular treatment (ligation or embolization of hepatic artery) in patients with hemangiomas of the liversince a surplus arterial flow in the tumors was found in 53.6% of observations.
