Effective segmental chemoembolization of advanced hepatocellular carcinoma with tumor thrombus in the portal vein 总被引:12,自引:0,他引:12
Tetsuya Katsumori M.D. Masato Fujita Takeshi Takahashi Osamu Satoh Shigeki Ichijima Toshiyuki Nakamura Hiroyuki Morishita Kohji Ohno Yasuhiko Nakano Tomoho Maeda 《Cardiovascular and interventional radiology》1995,18(4):217-221
Purpose: Evaluate therapeutic results of transcatheter segmental hepatic artery chemo-oily-embolization (segmental TAE) against advanced hepatocellular carcinomas (HCC) accompanied by portal tumor thrombus (PTT).
Methods: Segmental TAE was performed in nine patients with hepatic cirrhosis and advanced HCCs accompanied by PTT. Four subsegmental portal branches were obstructed by PTT in three patients, and two were obstructed in the remaining six patients. TAE was performed into the targeted segmental hepatic artery followed by embolization with gelatin sponge particles.
Results: In one patient undergoing subsequent resection, a marked anticancer effect on the PTT was demonstrated histologically. In the eight other patients who did not undergo subsequent resection, the cumulative survival rates were 67% at 6 months, 44% at 1 year, and 22% at 2 years. No serious complications were noted.
Conclusions: This therapeutic approach is thought to be a useful treatment for HCC with PTT, because it reinforces anticancer effects and can be performed more safely than conventional transcatheter arterial embolization. 相似文献

重视介入性肺减容术的研究 总被引:5,自引:2,他引:3
介入性肺减容术是在外科切除肺减容术和内镜下非外科切除肺减容术的基础上发展起来的。它是一项X线导引下的经导管治疗技术,在靶肺叶经支气管行博来霉素(或无水乙醇)碘油乳剂栓塞的同时并对其近端支气管用骨水泥封堵,可获得稳定的肺纤维化和肺减容,即所谓的功能性肺叶切除。虽然此项介入治疗技术目前仍处于动物实验阶段,但已经显露出其临床应用潜力和广阔的前景。 相似文献

四氧化三铁微粒与碘化油混悬液栓塞兔肾动脉的实验研究 总被引:1,自引:0,他引:1
目的 探讨四氧化三铁(Fe3O4)微粒与碘化油(Lp)混悬液(suspension from magnetic microspheres with lipi odol, S Fe3O4 Lp)对兔肾动脉的栓塞和导向作用机制。方法 测定工业工艺制备粒径为 50~250μm 5 种规格的 Fe3O4微粒在Lp中的沉降时间、速度;实验组用粒径250μm的S Fe3O4 Lp对右肾动脉栓塞,对照组用Lp栓塞。两组于术后不同时间比较栓塞效果、观察血生化和病理学改变。结果 五种粒度的Fe3O4 微粒能在一定时间范围内悬浮于Lp中;栓塞效果实验组优于对照组;实验组栓塞部位Fe3O4 微粒与Lp存留存在明显正相关关系(P<0.005,r=0.76)。结论 粒径为250μm的S Fe3O4 Lp对兔肾动脉栓塞效果好,无明显毒副反应;栓塞过程中Fe3O4 微粒与Lp具有同步、同向性,是S Fe3O4 Lp发挥导向性栓塞的基础。 相似文献

We describe a case of hepatocellular carcinoma in which a tumor embolus in the portal vein and 3 of 4 intrahepatic metastases were necrosed completely by Lipiodol transcatheter chemo-embolization (Lipiodol-TCE). Tumor emboli in the portal vein and intrahepatic metastases usually cannot be necrosed by conventional transcatheter chemo-embolization alone, because small nodules such as intrahepatic metastases and tumor emboli in the portal vein are supplied blood from the portal vein. However, in this case, Lipiodol-TCE was effective against tumor emboli in the portal vein and intrahepatic metastases. ACTA PATHOL JPN 38: 1363-1367, 1988. 相似文献

Selective effects of Lipiodolized antitumor agents 总被引:4,自引:0,他引:4

Lipiodol Ultra-Fluid (Lipiodol) remains selectively in the tumor for an extended time when applied through arteries feeding the tumor. Although lipophilic antitumor drugs are selective when combined with Lipiodol, wide application of common hydrophilic agents is limited, as these compounds are insoluble in oil. We propose "Lipiodolization" of water-soluble agents using as an intermediate Urografin, a water-soluble contrast medium. Thirteen patients with primary hepatocellular carcinoma were treated with this Lipiodol-Urografin system containing antitumor agents. Marked decrease in serum alpha-fetoprotein (AFP) levels, decrease in tumor size in the hepatic imaging, and histologic studies of the resected specimen revealed this mode of therapy to be effective in 10 of 13 patients (77%) with hepatocellular carcinoma. Lipiodolization of antitumor agents is a new approach to selective cancer chemotherapy. 相似文献

PURPOSE: The evaluation of new oily agents for targeting chemoembolization for hepatocellular carcinoma. METHODS: Five types of oily preparation were injected into the hepatic artery of 54 rabbits inoculated with VX2 carcinoma cells in order to evaluate (1) the safety of these preparations, (2) their histologic distribution and the amount of agents remaining at tumor sites, and (3) computed tomographic (CT) images obtained. Of these preparations, three were made by mixing non-iodinated poppy seed oil and a thickener and then adjusted to have a viscosity lower than, equal to, or higher than that of lipiodol. A fourth preparation was a mixture of lipiodol and a thickener with a higher viscosity than lipiodol alone, and the fifth preparation was lipiodol alone. RESULTS: (1) No injury to the hepatic parenchyma was observed hematologically or histologically. (2) With increase in the viscosity, a significantly larger amount of agent remained at the tumor site. No agent was present at normal sites 14 days after intraarterial injection, regardless of which preparation was given. (3) On CT scans following intraarterial injection, tumor cells were visibly deeply stained in the non-iodinated preparation groups, while the lipiodol groups were not evaluable because of excessively high attenuation. CONCLUSION: The non-iodinated oily preparations and highly viscous oily preparations developed in the present study were more useful than lipiodol for treatment of hepatic tumors. 相似文献
