AIM To investigate the source of blood supply of carvenous hemangioma of liver (CHL) and provide a feasibile treatment for CHL via hepatic artery. METHODS Ⅰ. Origin of blood supply of CHL: portovenography, hepatic arteriography and portal vein staining were performed in 5 patients. Two casts of hepatic blood vessels from resected specimen were observed. Ⅱ. Clinical data: Among 75 patients (30 males, 45 females, aged 25～57 years with a mean of 37 4). 56 were of solitary type (44 on the right lobe, 12 on the left with 4 having intraparenchymatoma) and 19 were of multiple type (9 on the right, 2 the left, 8 whole liver). Twenty two patients were treated by sclerosis, 50 by embolization via hepatic artery and 3 were excised. RESULTS In 5 cases with portography, the contrast medium did not enter the tumor, the tumor appeared as low denty area and the intrahepatic branches of portal vein were pushed aside. In 5 cases with portal vein staining, the normal liver parenchyma was stained deep blue, and the tumor was not stained. The tumor area appeared as a round vacant cavity in 2 specimen casts. In 72 patients treated with sclerosis a or embolization via hepatic artery or through interventional method, the tumors diminished by 10%～30% in diameter and no tumors grew larger. CONCLUSION The blood supply of CHL originates from the hepatic artery. Tumors treated with sclerosis and emblization decreased in size or got fiberized.
