[Hepatic artery embolization for primary hepatic carcinoma].

Twenty patients with primary hepatic carcinoma (PHC) treated by hepatic arterial embolization in our department from Dec. 1986 to Mar. 1987 are reported. There were 15 males and 5 females. The ages ranged from 34 to 75 years with an average of 50.7. Preoperative diagnosis and localization of the tumor were done by AFP, B-us, CT and angiography (right lobe 15 cases, left lobe 1 case, both lobes 4 cases). Celiac and superior mesenteric angiography was carried out by femoral artery approach and then highly selective hepatic catheterization was utilized for hepatic arterial embolization. Antitumor agent (5-Fu, adriamycin), iophendylate and foamy gel sponge were used for peripheral and proximal embolization. Manifestations were improved in most of the patients after embolization, such as relief of abdominal pain, improvement of appetite, decrease of tumor size. Total necrosis of the tumor was found in 2 patients who underwent surgery 1 month after embolization. The side effects of the posthepatic embolization such as, nausea, vomiting, abdominal pain and fever could be relieved by symptomatic treatment. No severe complications, such as gangrene of the gall bladder, hepatic failure, liver abscess, intestinal necrosis or pulmonary embolization were found except 3 patients who died of renal failure after the procedure. The liver dys-function returned to normal within 2 weeks. Hepatic arterial embolization provides an alternative treatment for the patients with PHC who has compensated liver function without severe systemic diseases, especially renal endocrine problems and severe portal hypertension. They should have patent portal system as proved by angiography. The authors considered that this therapeutic embolization with hepatic chemotherapy infusion is safe and effective in the management of PHC. It may increase the resectability and provide palliative means for the advanced and terminal cases.
