Radiofrequency ablation (RFA) for thoracic tumours has emerged as a minimally invasive therapy option for primary and secondary lung tumours and has gained increasing acceptance for pain palliation. The procedure is well tolerated and the complication rates are low. RFA provides the opportunity for localized tissue destruction of limited tumour volumes with(More)
Assess the safety and evidence of efficacy of RFA for colorectal (CRC) lung metastases with follow up to 1 year. Twenty-three patients had percutaneous RFA for 52 colorectal pulmonary metastases under fluoro-CT. Patients received IV conscious sedation and local analgesia with routine hospitalisation/monitoring for 24 h post RFA. Patients had CT scanning at(More)
BACKGROUND The lung is the most common site for primary cancer worldwide as well as being a common site of metastases for various malignancies. Percutaneous radiofrequency ablation (RFA) is rapidly evolving as a new minimally invasive tool for the treatment of pulmonary tumors. PATIENTS AND METHODS A questionnaire was sent by e-mail to 14 centres around(More)
OBJECTIVE We sought to evaluate the effect of radiofrequency ablation (RFA) on pulmonary vessels with respect to potential of injury of these structures, to assess perfusion-mediated "heat sink" effect, and to consider acute and chronic complications. MATERIAL AND METHODS RFAs targeted to perihilar, middle third, and peripheral lung regions were created(More)
BACKGROUND The purpose of this work was to assess the feasibility and safety of applying radiofrequency to lung parenchyma adjacent to the heart and to evaluate the clinical impact and the histopathological damage to the heart caused by radiofrequency electrodes penetrating the pericardium and the myocardium. MATERIALS AND METHODS Three sheep underwent(More)
PURPOSE To retrospectively evaluate the feasibility and outcome of using high-powered percutaneous microwave ablation (MWA) in treating medically inoperable early stage non-small cell lung cancer. MATERIALS AND METHODS From November 2010 to June 2012, 15 patients underwent CT-guided MWA of 15 tumours in 16 sessions. One patient had a second ablation(More)
OBJECTIVE To evaluate the prevalence of azygos arch valves and assess azygos valve insufficiency at computed tomography angiography (CTA) of the chest or body with high rate contrast material injection. METHODS Three hundred twenty-one CTAs using high intravenous injection rates (3-5 mL/second) of 300 mgI/mL contrast material were retrospectively(More)
INTRODUCTION This study aimed to assess the safety and efficacy of imaging-guided percutaneous radiofrequency ablation (RFA) for local control of lung metastases from colorectal cancer (CRC). METHODS Twenty patients with lung metastases from CRC were treated with a RITA Starburst XL electrode and RITA 1500 generator using temperature control and impedance(More)
BACKGROUND Preliminary results have shown that percutaneous radiofrequency ablation (RFA) may play a useful role in patients with inoperable lung tumors. This series evaluated the prognostic features for survival in nonsurgical candidates who underwent percutaneous RFA of pulmonary metastases from colorectal carcinoma. METHODS Fifty-five patients not(More)
