Ultrasound-guided percutaneous radiofrequency catheter ablation observe the curative effect of HCC

Objective To explore ultrasound-guided percutaneous radiofrequency catheter ablation the curative effect of HCC and security.Methods Retrospective analysis of RF treatment 37 cases of liver cancer patients of material,the application of mianyang,sichuan LDRF-120S multipole radiofrequency ablation instrument,the maximum power for 90 watts,electrode open as umbrella,for rotary cluster muti-warhead electrode,the treatment of power and electrode open by computer the size real-time monitoring,tumor ablation after completely,impedance to achieve maximum,power reduction is zero,and treatment to be automatic stop.For more than 5cm in diameter of liver cancer patients with hepatic artery catheter first by embolization chemotherapy(TACE) joint radiofrequency catheter ablation.Diameter less than 5cm of liver cancer,direct application radiofrequency ablation therapy,patients were followed up 3 years,1 month,3 months,6 months,1 year,2 year,3 year,and CT or MRI enhancement and AFP follow-up.Results(1) color dopplar ultrasound,CT scan and MRI review,1,2,3 years survival rates were 83.7%,56.8% and 51%.(2) a tire protein(AFP) : 13 cases before and after treatment were not rise,24 cases before treatment AFP in(641 + 61.24 u g/L) after one month dropped 136.41 + /-52.23 u g/L),including 16 cases fell to the normal range.(3) complications: after 3 d have different levels of heat,temperature of 37.4 ℃ to 39.Nausea and vomiting in 1,abdominal pain,right shoulder pain 3 cases.Conclusion Radiofrequency catheter ablation liver tumor is a therapeutic effect,safety high reliable minimally invasive treatment technology,is worth further application.
