超声引导经穿刺针内腔门脉留置导管化疗——动物实验及临床初步应用

门脉留置导管化疗是肝癌治疗的一条较好途径，具有一定疗效。以往超声引导穿刺置管技术较复杂。本文对门脉穿刺技术进行了新的研究。穿刺针选用１８ＧＰＴＣ针，内径１．０ｍｍ，导管外径０．９ｍｍ。导管直接从１８Ｇ穿刺针针腔内送入门脉留置。导管可从门脉右前或左枝矢状部进入门脉主干。穿刺顺利，患者易耐受，经肝素处理的导管留置三天仍保持通畅，无明显并发症。我们认为：超声引导下的门脉穿刺留置导管化疗可望成为肝癌非手术治疗的常用方法之一

Intraportal Chemotherapy via Retained Catheter Inserted through PTC Needle under Ultrasonic Guidance-Animal Experiment and Preliminary Clinical Application

Repeated intraportal chemotherapy is effective in the treatment of liver cancer. The technique to insert a catheter under ultrasonic guidance was complex in the past. Study on the improvement of the technique was done. A 18G PTC needle with inner diameter 1.0 mm and catheter with outer diameter 0.9 mm were used. The catheter was advanced through the lumen of PTC needle. The catheter was inserted into main portal vein through right anterial portal vein or the vertical portion of left portal vein. This procedures were successfully carried out in 4 patients with no obvious complication. The catheter treated by heparin could remain patent for at least 3 days. It seems that repeated intraportal chemotherapy via a catheter inserted under ultrasonic guidance may become one of commonly used non invasive treatments for liver cancer.
