Local ablative techniques have been developed to enable local control of unresectable tumors. Ablation has been performed with several modalities including ethanol ablation, laser ablation, cryoablation, and radiofrequency ablation. Microwave technology is a new thermal ablation technique for different types of tumors, providing all the benefits of(More)
PURPOSE The aim of our study was to assess the diagnostic capabilities of multidetector CT in the evaluation of the small bowel in different pathological conditions, with the use of oral hyperhydration with isotonic solution. MATERIALS AND METHODS The study retrospectively evaluated 106 patients who underwent multidetector CT of the small bowel. Four(More)
Our aim was to assess the usefulness of volumetric analysis for the follow-up of abdominal aortic aneurysms after endovascular repair (EVAR) and operator independence of the method. We retrospectively evaluated 99 computed tomography (CT) exams of 33 patients. Two blinded operators assessed the volume before treatment and after EVAR at 1–3 and 12–24 months.(More)
Mammary-type myofibroblastoma is a very rare, benign, spindle cell lesion, arising mainly in the inguinal region. This clinical entity strictly duplicates the features of its breast counterpart. To our knowledge, this is the first report of this particular lesion occurring in the popliteal fossa. We discuss the clinical, radiological and histopathological(More)
Metastatic bone disease is the most common cause of malignancies to the skeleton in adults. The treatment of bone metastases is frequently palliative aiming to achieve a satisfactory control of pain and to prevent or to treat pathological fractures. In selected cases the resection of a single bone metastasis may improve the survival of the patients. Our(More)
The purpose of our study was to retrospectively evaluate the feasibility, safety and effectiveness of microwave ablation (MWA) in nine patients with unresectable lung tumour. Ten lesions were treated in ten ablation sessions in nine patients. The treatments were performed with a microwave generator with 45 W and 915 MHz connected to a 14.5-gauge antenna for(More)
The purpose of this study was to evaluate the safety and efficacy of percutaneous ultrasound (US)-guided radiofrequency ablation (RFA) in patients with intrahepatic cholangiocarcinoma (ICCA) in a small, nonrandomized series. From February 2004 to July 2008, six patients (four men and two women; mean age 69.8 years [range 48 to 83]) with ICCA underwent(More)
To assess the feasibility and effectiveness of emergency endovascular treatment of abdominal aortic aneurysms (AAAs). During 36 months we treated, on an emergency basis, 30 AAAs with endovascular exclusion. In 21 hemodynamically stable patients preoperative CT angiography (CTA) was performed to confirm the diagnosis and to plan the treatment; 9 patients(More)
The treatment of pain in bone metastases is currently multidisciplinary. Among the various therapies, local radiotherapy is the gold standard for pain palliation from single metastasis, even though the maximum benefit is obtained between 12 and 20 weeks from initiation. In carefully selected patients, several ablation therapies achieve this objective in 4(More)
The aim of this study was to assess the effectiveness of endovascular treatment of isolated iliac artery aneurysms (IAAs). Between March 1999 and March 2004, 15 isolated IAAs in 13 patients (mean age: 71.8 years) were selected for endovascular repair by means of a covered stent or stent-graft: 12 were in the common iliac artery (2 with the proximal end 12(More)
