【摘要】 目的报道高频热水行肝癌消融治疗的2例病人,并与微波、激光消融进行比较。方法电视透视或CT导向下,用HITT针刺入肝癌病灶中残留活癌区域,使用温度为85℃,消融直径5cm,时间5min。结果1例病灶明显缩小,AFP降至正常,至今已存活一年半。另1例为肠癌肝转移,术后3个月CT示残癌无增强,CEA已降至正常,至今已存活两年。结论HITT是肝癌TAE后较好的局部消融方法,与微波、激光等相比,有一定的优势。更多还原

【Abstract】 Objective In this article the methods and results of local ablation for hepatic carcinoma using HITT in two cases were reported, and the therapy was comparatively studied with microwave coagulation and radio frequency ablation. Methods Under the guidance of fluoroscope or CT, the HITT needle was introduced into the remnant of the hepatic carcinoma lesion. Under a temperature of 85℃, the ablation was completed in an area of 5cm in diameter with duration of 5 minutes. Results In one patient with hepatocellular carcinoma, the lesion’s dimension decreased significantly, and the level of alpha-fetoprotein (AFP) dropped to normal after the intervention was done. And the patient had survived for 18 months. Another case was hepatic metastasis from rectal carcinoma after the primary tumor was removed. Three months after HITT, no more enhancement could be seen within the lesion. The level of carcinoembryonic antigen (CEA) had turned back to normal. Now the patient had survived for 2 years. Conclusion HITT is an effective post-TAE local ablation procedure for hepatic carcinoma, which is superior to microwave coagulation or radiofrequency ablation.更多还原
