为评价经皮穿刺热盐水注射治疗法(PSIT)在治疗肝细胞癌(HCC)中的有效性。作者对20例有23个肝癌结节的病人行PSIT,所有肿瘤的直径均小于30mm。23上结节中的17个HCC是通过细针穿刺活检获得病理证实,其余6个结节HCC是通过影象学诊断的(US、CT、MRI和血管造影)。在超声的引导下,1～2ml的1％利多卡因局麻后,用21号20cm长穿刺针经皮穿入通过肝脏进入肿瘤。生理盐水加热到尽可能高的温度,然后用一个玻璃注射器
To assess the effectiveness of percutaneous thermal saline injection (PSIT) in the treatment of hepatocellular carcinoma (HCC). The authors performed PSIT on 20 patients with 23 hepatocellular carcinoma nodules. All tumors were less than 30 mm in diameter. Twenty-seven HCCs in the upper nodules were confirmed pathologically by fine-needle aspiration biopsy, and the remaining six nodules were diagnosed by imaging (US, CT, MRI, and angiography). Under the guidance of ultrasound, 1 to 2 ml of 1% lidocaine after local anesthesia, with a 21st 20cm puncture needle through the liver into the tumor. Normal saline is heated to the highest possible temperature, then use a glass syringe
