We describe epicardial ablation using a 2-port, right-sided, thoracoscopic approach for pulmonary vein isolation on the beating heart in the treatment of atrial fibrillation. Our early success rate with this procedure for the epicardial lesion pattern is 86%. Utilizing new ablation energy sources, such as laser and microwave, this port access approach offers surgeons a true minimally invasive, ...

Tumor ablation is a minimally invasive technique used to deliver chemical, thermal, electrical, or ultrasonic damage to a specific focal tumor in an attempt to achieve substantial tumor destruction or complete eradication. As the technology continues to advance, several image-guided tumor ablations have emerged to effectively manage primary and secondary malignancies in the liver. Percutaneous ...

Using laser-ablation molecular-beam Fourier transform microwave (LA-MB-FTMW) spectroscopy two new conformers of proline have been identified together with the two previously observed (Angew. Chem. Int. Ed., 2002, 41, 4673).

Thermal ablation of liver tumors near large blood vessels is affected by the cooling effect of blood flow, leading to incomplete ablation. Hence, we conducted a comparative investigation of heat sink effect in monopolar (MP) and bipolar (BP) radiofrequency ablation (RFA), and microwave (MW) ablation devices.With a perfused calf liver, the ablative performances (volume, mass, density, dimensions...

Tumour ablation is clinically applied mainly for non-operable liver tumours, with increasing application to other organ sites like kidney, lung, adrenal gland and bone. Most current devices use radiofrequency (RF) current to heat tumour tissue surrounding the applicator, which is introduced into the tumour under imaging guidance. Tissue temperatures in excess of 100 degrees C are achieved, with...

Microwave (MW) ablation is becoming a routine technology in the interventional radiology field. A new approach combining MW and chemical developed this paper. The rationale for development of Microwave-Assisted Chemical Ablation (MA-CA) was to improve utility thermal as minimally invasive treatment cancer. experimental conditions ex vivo bovine liver samples were: A—100 W (120 s) with no additi...

Percutaneous thermal ablation is an emerging treatment option for many tumors of the abdomen not amenable to conventional treatments. During a thermal ablation procedure, a thin applicator is guided into the target tumor under imaging guidance. Energy is then applied to the tissue until temperatures rise to cytotoxic levels (50-60 °C). Various energy sources are available to heat biological tis...

To retrospectively compare the efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) in the treatment of pulmonary tumors, a total of 75 patients with lung tumor who underwent thermal ablation therapy in Guangdong General Hospital into the study from March 2007 to December 2014 were enrolled. Of the patients, 43 received radiofrequency ablation and 32 received microw...

PURPOSE Radiofrequency ablation (RFA) and microwave ablation (MWA) are the two main percutaneous techniques for the treatment of unresectable hepatocellular carcinoma (HCC). However, to date, studies comparing the two therapies have provided discordant results. The aim of this meta-analysis is to evaluate the efficacy and safety of the two treatments for HCC patients. MATERIALS AND METHODS A ...

Microwave ablation, as an emerging method for treating lung cancer, has been widely used because of its advantages, such being less invasive and having fewer side effects compared with other therapies, surgery chemotherapy. The key to microwave ablation is destroy the tumor tissue while minimizing damage caused surrounding healthy tissues. Based on heat transfer model porous media, a two-dimens...
