Abstract

30 haemangiomas and surrounding liver tissues removed surgically are studied histologically. 11 patients underwent endovascular occlusion of the hepatic artery peripheral branches at various intervals before the operations. The lack of reaction of the vascular wall to the X-ray noncontrast emboli and minimal reaction to the X-ray contrast emboli were found. The persistence of the vascular lumen occlusion is proved. The degree of the haemangioma blood filling is reducing, the cavernae recede and the tumour sclerosis occurs after the endovascular occlusion. Aseptic necrosis in the haemangioma and small necrosis of liver tissue are possible.
