Hepatic telangiectasia in Osler's disease treated with arterial embolization. Report of 2 cases.

Hepatic hereditary telangiectasia in 2 females was treated with hepatic artery embolization. In one patient both peripheral and central arterial occlusion was performed; the patient died of massive gastro-intestinal bleeding for 2 months later. Autopsy showed extensive regions with necrosis in the right liver lobe. In the next patient only central occlusion of the right hepatic artery was performed and the arterio-venous shunting in the left liver lobe left remaining. After a long reconvalescence period the patient recovered completely. It is advocated to centrally occlude only that hepatic artery supplying the most affected parts of the liver in Osler's disease. Thus extensive necrosis with possible ensuing death may be avoided.
