In 8 cases of hepatocellular carcinoma, hepatectomy was performed after hepatic artery embolization with Gelfoam. Complete necrosis of the tumor was found in 4 of these cases. Compared with the tumors that showed incomplete necrosis, the tumor in the complete necrosis group were small, thickly encapsulated, and located at sites remote from collateral circulation. Angiography and computed tomography after embolization accurately demonstrated tumor necrosis or continued viability, as confirmed by examination of resected specimens.

The authors report a case of needle tract implantation of hepatocellular carcinoma following percutaneous biopsy of the liver. The patient, a 62-year-old Japanese male, was found to have a small hepatocellular carcinoma diagnosed by needle biopsy; this was followed by transcatheter chemoembolization, a combination of transcatheter arterial infusion of adriamycin and transcatheter arterial embolization of Gelfoam, and right lobectomy. Eight months after the biopsy and the lobectomy, a nodule of hepatocellular carcinoma, measuring 3.5 cm in diameter, was found at the site of the previous biopsy and excised. The patient is doing well without further recurrence of tumor 23 months after the lobectomy and 15 months after the excision of the implanted tumor in the subcutis.

We report the development of an extensive acute gastric ulcer in a 60-year-old man following therapeutic transcatheter hepatic artery embolization for hepatoma. The unintentional occlusion of branches of the right gastric artery with refluxed Gelfoam fragments is thought to be responsible. This complication is probably rare, but should be kept in mind when therapeutic embolization of the hepatic artery is performed.

A histopathologic study was done on livers from 14 patients who underwent surgery for hepatocellular carcinoma and who had been pretreated by a combination of intra-arterial embolization of Gelfoam (Upjohn) plus intra-arterial chemotherapy. This technique was effective as the excess vascularity of the tumor and the tumor bulk were reduced and resection was readily facilitated. For solitary tumors of less than 4 cm in diameter, this approach was particularly effective. As this combined treatment almost invariably leads to liquefaction and necrosis of the tumor, the likelihood of metastases is diminished.

The degree of hepatocellular carcinoma vascularity in eight patients was assessed with Tc-99m MAA radionuclide angiography before and after treatment. For chemoembolization therapy, lipiodol and doxorubicin hydrochloride were administered intraarterially along with Gelfoam particles. The ratio of radioactivity in the hepatocellular carcinoma compared to that in the surrounding uninvolved tissue before therapy was 6.5-19.0 with a mean of 12.0. After therapy, the ratio dropped to 0.5-1.3. Because survival improved significantly after the therapeutic regimen used in these patients, radionuclide Tc-99m MAA angiography appears to be an accurate method for demonstrating successful embolization of the vascular supply in hepatocellular carcinoma.

Thirty-three consecutive patients with previously untreated hepatocellular carcinoma (HCC) and 6 patients with recurrent HCC were treated with transcatheter arterial embolization (TAE). The patients were not eligible for surgical resection or percutaneous ethanol injection. TAE was performed with Lipiodol Ultra-Fluid, epidoxorubicin and Gelfoam, with a mean of 1.7 treatments per patient. CT was performed 15 days after TAE. The mean cumulative survival was 14.2 months in patients with previously untreated HCC. The survival of patients stages Okuda I and II did not differ significantly (p > 0.05); tumor size did not affect survival (p > 0.05). Two patients with recurrent HCC died 7.0 and 9.3 months after the diagnosis of tumor recurrence; the remaining 4 patients are still alive with a maximum follow-up of 22.5 months from the diagnosis of HCC recurrence. Ten complications occurred in 8 patients, and were controlled by medical therapy. Eleven patients died during the study; no death was related to TAE. The series was not randomized, but comparison with the natural history of HCC suggests that TAE is effective as palliative treatment of advanced or recurrent HCC.

One hundred and fourteen consecutive patients with unresectable hepatocellular carcinoma were treated by chemoembolization using ethiodized oil (Lipiodol), anticancer agents. Ninety patients had concomitant chronic liver disease. Hepatocellular carcinoma (HCC) was diagnosed by US, contrast enhanced CT, fine needle biopsy and alpha-feto-protein level. Admission criteria were as follows: tumor confined to the liver with or without hilar nodal involvement, Child class A or B, white blood cell count above 2.000/mmc and platelet count above 75,000/mmc. All the patients underwent angiographic chemoembolization with Lipiodol and anticancer agents. In 98 patients we performed transcatheter hepatic arterial embolization (TAE) with Gelfoam or for Ivalon sponge. In 16 patients TAE was not performed because of portal thrombosis (7 cases) or technical reasons (9 cases). Mitomycin was used in 40 patients and dihydroxyanthracenedione (DADH) in 58 patients. In the TAE group 83 patients were Child A and 15 Child B. In 27 patients HCC was mononodular whereas in 71 it was multinodular. In 41 patients the tumor was more than 5 cm in diameter (in multinodular tumors only the larger lesion was taken into account). In 56 patients chemoembolization plus TAE was repeated. Seven patients died within one month after treatment: two from myocardial infarction, two from liver failure, two from digestive haemorrhage and one from necrotizing pancreatitis. Long-term survival rates were investigated in relation to prognostic factors: anti-cancer agent, number of nodes, tumor size and Child stage using Kaplan-Meier method. Survival rate at 12, 24 and 36 months are 64%, 38%, and 30% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Intra-arterial digital subtraction angiography using CO2 (CO2-IA-DSA) is effective for detecting arteriovenous and arterioportal shunts in the liver. We carried out CO2-IA-DSA in addition to selective arteriography using a iodinated contrast medium in 31 patients with unresectable hepatocellular carcinoma (HCC). As a result, CO2-IA-DSA detected an AV shunt in 4/31 patients and an AP shunt in 16/31 patients for a total of 20 cases of shunt, whereas conventional hepatic IA-DSA detected only AP (AV shunt) shunts in 3/31 patients. For HCC without any shunt, Gelfoam embolization was carried out after injection of Lipiodol and Farmorubicin (FARM). In patients with an AP shunt, injection of Lipiodol and FARM was performed after the shunt had been embolized with Gelfoam. In patients with an AV shunt, Lipiodol and FARM were injected after the shunt had been embolized with a metallic coil. In conclusion, detection of shunts by CO2-IA-DSA is useful for determining the optimal approach for transcatheter arterial injection.

For the purpose of achieving emergency hemostasis of a ruptured hepatocellular carcinoma (HCC) or prevention of such rupture, we applied a new method of transcatheter therapy: intra-arterial alcoholization. Five patients with a ruptured HCC and 42 with an impending rupture were treated by intra-arterial injection of absolute ethanol mixed with an equal volume of iodized oil, Lipiodol (EtOH-Lp). The tumor size ranged from 4 to 26 cm (mean 7.8 cm) in diameter. The catheter tip was placed in the segmental branch or a more distal position of the hepatic artery, and 2-40 (mean 10.6) ml of EtOH-Lp was infused under fluoroscopic guidance. Infiltration of ethanol into the HCC mass was recognized as a dense deposition of Lipiodol on plain abdominal X-rays and computed-tomography. In all five cases of ruptured HCC, hemostasis was achieved. In all 42 cases of impending rupture, tumor rupture was prevented, and all except 3 patients could be discharged. No significant complication of the gastrointestinal tract or biliary tract was seen. The incidence and severity of postembolization syndrome was markedly lower than those seen in cases treated with Gelfoam embolization.

We retrospectively reviewed computed tomographic (CT) findings of 118 patients with hepatoma who received sequential follow-up CT after transcatheter arterial embolization (TAE). Thirty-five patients received TAE using Gelfoam particles with cisplatin, 37 patients using Gelfoam particles and iodized oil (Lipiodol) with cisplatin, and 46 patients using iodized oil with cisplatin. Liver atrophy was observed in 33 patients, lobarly or focally, depending on the embolized area. It was frequently associated with portal vein occlusion by the tumor, usage of iodized oil, and repeated embolization therapy. The lobar atrophy was seen in patients who had portal vein occlusion and/or received repeated embolization therapy. The focal atrophy was observed in patients who were administered iodized oil. Infarction developed in four patients who had a thrombus in the portal vein and received peripheral embolization therapy using iodized oil. We conclude that liver parenchymal changes occur frequently in patients who have portal vein occlusion and/or receive peripheral embolization using iodized oil.
