Background In recent years liver resection has increasingly been performed. Bleeding and hepatic acute failure, secondary to vascular inflow occlusion (Pringle’s manoeuvre), remain significant complications; these problems seem to be higher in older patients and in those with cirrhosis. Several surgical tools such as CUSA, Harmonic scalpel, Bipolar scissors, Ligasure diathermy, have been develo...

OBJECTIVE To describe a technique for internal nasal valve collapse using radiofrequency-induced thermotherapy (RFITT). DESIGN Prospective study. SETTING Academic research center. PATIENTS A total of 28 patients with nasal obstruction due to inspiratory nasal valve collapse were included in this study. INTERVENTION Radiofrequency-induced thermotherapy. MAIN OUTCOME MEASURES Visual ana...

The safety of weekly regional hyperthermia performed with 8 MHz radiofrequency (RF) capacitive heating equipment has been established in rectal cancer. We aimed to standardize hyperthermia treatment for scientific evaluation and for assessing local tumor response to RF hyperthermia in rectal cancer. Forty-nine patients diagnosed with rectal adenocarcinoma were included in the study. All patient...

To implement noninvasive thermometry, we installed a hybrid system consisting of a radiofrequency multiantenna applicator (SIGMA-Eye) for deep hyperthermia (BSD-2000/3D) integrated into the gantry of a 1.5 Tesla magnetic resonance (MR) tomograph Symphony. This system can record MR data during radiofrequency heating and is suitable for application and evaluation of methods for MR thermography. I...

Magnetic nanoparticle based hyperthermia emerged as a potential tool for treating malignant tumours. The efficiency of the method relies heavily on knowledge magnetic properties samples; in particular, frequency dependent complex susceptibility is vital to optimize irradiation conditions and provide feedback material science developments. We study frequency-dependent an aqueous ferrite suspensi...
