An error-controlled mesh refinement procedure for needle insertion simulations is presented. As an example, the procedure is applied for simulations of electrode implantation for Deep Brain Stimulation. We take into account the brain shift phenomena occurring when a craniotomy is performed. We observe that the error in the computation of the displacement and stress fields is localised around the needle tip and the needle shaft during needle insertion simulation. By suitably and adaptively refining the mesh in this region, our approach enables to control, and thus to reduce, the error whilst maintaining a coarser mesh in other parts of the domain...

PURPOSE: To evaluate safety, feasibility, and efficacy of percutaneous cryoablation of breast tumors in patients with clinically stable metastatic breast cancer, and to compare the findings with reports on alternative procedures, namely surgery and local radiotherapy. METHODS: Seventeen female patients (average age of 54.8 years +/- 10.8 ; range 37-72) with primary breast tumor not surgically treated because of metastatic disease were included. Patients were treated for their primary lesion by percutaneous cryotherapy in period of stable disease...

Background: Tumoral macrovascular invasion (MVI) of hepatic and/or portal vein branches is a common phenomenon in hepatocellular carcinoma (HCC) and is associated with poorer prognosis when compared to HCC without MVI. Summary: Current international guidelines for the management of HCC recommend sorafenib as the only treatment option in case of MVI. Despite guideline recommendations, several alternative options have been tested to manage HCC with MVI: surgery, transarterial chemoembolization, external or internal radiation, hepatic arterial infusion chemotherapy, percutaneous treatment, cryotherapy, or the combination of two or more of these strategies, with or without sorafenib...

BACKGROUND: Cryoablation has emerged as an alternative to the more invasive partial nephrectomy for small renal masses. The approach can be carried out by two techniques, either laparoscopic (LCA) or percutaneous with CT guidance (PCA). We aimed to compare between the two procedures. MATERIAL & METHODS: A systematic review and meta-analysis was conducted including studies comparing the two techniques. Outcomes included incomplete ablation, late local recurrence, cancer specific survival, procedure time, transfusion rates, hospital stay, and complications...

OBJECTIVES: Ablative treatment (AT) rise is foreseen, validation of steps to insure good proceedings is needed. By looking over the process of the patient, this study evaluates the requirements and choices needed in every step of the management. METHODS: We searched MEDLINE(®), Embase(®), using (MeSH) words and we looked for all the studies. Investigators graded the strength of evidence in terms of methodology, language and relevance. RESULTS: Explanations of AT proposal rather than partial nephrectomy or surveillance have to be discussed in a consultation shared by urologist and interventional radiologist...

INTRODUCTION: Surgery remains the gold-standard curative treatment for localized (T1) renal carcinoma. However, recent medical-technological advances have led to the development of new minimally invasive treatment options, one of which is percutaneous cryoablation. AIM: To assess the effectiveness and safety of ultrasound-guided percutaneous cryoablation of renal tumors. MATERIALS AND METHODS: The study comprised 12 patients aged 52 to 76 years who underwent ultrasound-guided percutaneous cryoablation of renal tumors from 2015 to 2017...

Main indications of percutaneous pulmonary thermal ablation are early stage non-small cell lung carcinoma (NSCLC) for patients who are not amenable to surgery and slow-evolving localized metastatic disease, either spontaneous or following a general treatment. Radiofrequency ablation (RFA) is the most evaluated technique. This technique offers a local control rate ranging between 80 and 90% for tumors <3cm in diameter. Other more recently used ablation techniques such as microwaves and cryotherapy could overcome some limitations of RFA...

Advances in cancer treatments have lengthened the survival of patients with bone metastases. Optimal control of the symptoms and prevention of the complications associated with bone metastases improve quality of life. Achieving these goals increasingly involves interventional radiology procedures. These include bone consolidation and analgesic techniques such as cementoplasty (vertebroplasty at the spine); percutaneous implantation of screws, metallic reinforcement devices, or intraosseous implants; and tumor destruction using thermal methods (radiofrequency and cryotherapy), chemicals (alcohol), and drugs (chemoembolization), which have fewer indications...

The increased use of abdominal imaging has led to a major increase in small renal tumors incidence particularly in the elderly population. Their management is evolving with the development of percutaneous ablation, particularly radiofrequency ablation, cryoablation, and microwave ablation. The typical indications that must be validated by a multidisciplinary committee include solid tumors less than 3cm in patients with multiple comorbidity factors (including age), contraindications to surgery, hereditary renal cancer, bilateral renal tumors, solitary kidney, pre-existing chronic kidney disease, or at high risk of predialysis renal function after partial nephrectomy...

OBJECTIVES: To investigate whether persistent enhancement detected on contrast-enhanced sonography at postoperative day 1 (early contrast-enhanced sonography) after cryoablation of renal tumors implies the presence of residual viable tumor tissue, defined as residual enhancing tissue on reference imaging (computed tomography or magnetic resonance imaging) performed 6 months after the procedure. METHODS: Seventy-four patients with percutaneous cryoablation of renal tumors had early contrast-enhanced sonography from November 2011 to August 2015...

OBJECTIVE: The purpose of this article is to delineate the potential techniques for percutaneous ablation of breast cancer, discuss the advantages and disadvantages of each technique, and provide results from recent studies on these technologies. The techniques discussed are cryotherapy, laser irradiation, microwave irradiation, radiofrequency ablation, high-intensity focused ultrasound ablation, and irreversible electroporation. CONCLUSION: Although percutaneous ablation techniques have some promising potential for less-invasive treatment of breast cancer, larger multicenter trials are needed to confirm their efficacy, especially in comparison with the reference standard of lumpectomy...

Bleeding and hematoma formation is rarely reported in percutaneous vertebroplasty procedure. An 84 year old male presented with a large paraspinal muscle hematoma after a percutaneous vertebroplasty. The patient had neither any prior bleeding disorder nor any anticoagulant treatment. Vital signs of the patient were unstable, and his hemoglobin level decreased daily. After a month of conservative treatment, including transfusion, cryotherapy, pain control and bed rest, his hemoglobin level remained stable and he showed relief from pain...

This report presents 4 patients (mean age, 22 y; range, 17-26 y) with facial arteriovenous malformations (AVMs) who underwent arterial ethanol and N-butyl cyanoacrylate embolization followed by percutaneous cryoablation of residual inaccessible AVMs. After the procedure, minor complications classified as type B according to the Society of Interventional Radiology (SIR) classification system occurred in 75% (3/4) of patients. One patient achieved 90% obliteration of AVM, and 3 patients had complete obliteration of AVM at 1-year follow-up...

The detection of peripheral lung nodules is increasing because of the expanded use of CT imaging and implementation of lung cancer screening recommendations. Although surgical resection of malignant nodules remains the treatment modality of choice at present, many patients are not surgical candidates, thus prompting the need for other therapeutic options. Stereotactic body radiotherapy (SBRT) and percutaneous thermal ablation are emerging as viable alternatives to surgical resection. For safety, efficacy, and cost-effectiveness purposes, however, alternative bronchoscopic methods for treatment of peripheral lung cancer are currently under active exploration...
