Conclusion Prior right upper quandrant surgery and repeated RF ablation of tumors adjacent to bowels are high risk factors of bowel injury in RF treatment.
Results After treatment 103 (61%) of 167 nodules reduced in size and blood flow singles of the tumors disappeared in 116 (79%),The Vmax of hepatic artery decreased significantly (89.5±36.0 cm/s vs 63.6±26.0 cm/s P <0.01) before and after RF treatment.
The success rate of single session of RF treatment was 89.8% (53/59 tumors) with a recurrence rate of 15.3% (9/59 tumors) in this study. Eleven cases (20.0%) were subsequently converted to surgery or intraoprative RF ablation and other methods.
RF treatment result: treatment group, cured 5 cases, significantly efficacy 13 cases and 16 cases with effective and 8 cases were of non-effect; the total effect rate was 73.81%.
Results After one week by RF treatment,CT imaging of 31 cases showed low density field enlarged and only tumor edges enhanced. The tumor size decreased 30% in 80% patients.
RF treatment can, therefore, potentially provide an effective and rapid quarantine treatment as an alternative to MB fumigation for certain pathogen-wood combinations.
It is proposed that RF treatment results in the formation of a porous gel layer of hydrous titanium dioxide on the surface of the anatase particles that subsequently undergoes a slow ion-exchange reaction involving ions of the supporting electrolyte.
おe are planning to cure this kind of disease by using radiofrequency (RF) capacitive hyperthermia and stereotaxic technique. According to the principle and specific property of RF heating inductively, we analysed the influence factors of RF heating and found that there are obvious differentials on heating time and temperature among different reports. There are no experimental foundation of precise relationship between heating temperature、time and the desired lesion size extent.We applica...
Objective To evaluate the results and feasible methods of sonographically-guided Radio-Frequency ablation for the treatment of primary or secondary hepatocellular carcinoma.Methods 180 patients with hepatocellular carcinoma were treated with percutaneous,ultrasound-guided RF ablation.RF was applied with frequency at 20W to 90W for 15 minutes,over multi-treatment session.After RF treatment,the AFP level changes were observed.The ultrasonography ,Computed Tomograph...
Objective Summarize the experience of nursing care for the patients under percutaneous transhepatic hepatocarinoma ablation with radiofrequency by using a clustered electrode technique. Methods Observe the results of twenty\|six cases of hepatocarcinoma with RF treatment by comparing preoperative and postoperative image data,tumor size and AFP value. Results The material of followup one to three months after the operation showed the tumor size decreased 40% in average.The blood supplement in ...
