Percutaneous cryotherapy

Aymeric Becq, Gabriel Rahmi, Guillaume Perrod, Christophe Cellier
Gastrointestinal angiodysplasia (GIA) is an acquired vascular superficial lesion, which presents typically as a bright red, irregular, round-shaped, slightly elevated lesion. GIAs are often seen in patients over 60 years of age and are mostly located in the colon (cecum and ascending).The cause and mechanisms of GIA have yet to be completely understood. Small-bowel GIAs are often diagnosed in the setting of obscure gastrointestinal bleeding (OGIB). In some cases, GIAs are associated with aortic stenosis, Von Willebrand's disease, chronic renal disease, and liver disease...

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...

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...

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...

Hepatocellular carcinoma is the major complication of chronic liver diseases and particularly of cirrhosis whatever its etiology. Once encountered mainly in the endemic countries of hepatitis B and C, the incidence of hepatocellular carcinoma (6/100,000) is parallel to the global development of diabetes, overweight and alcohol consumption. Little progress has been made for this cancer, whose mortality is 100 % at 10 years. Liver transplantation is the only truly curative treatment (survival more than 50 % at 10 years) since it allows the eradication of hepatocellular carcinoma and its essential cause, cirrhotic liver...

Percutaneous musculoskeletal procedures are widely accepted as low invasive, highly effective, efficient and safe methods in a vast amount of hip pathologies either in diagnostic or in therapeutic management. Hip intra-articular injections are used for the symptomatic treatment of osteoarthritis. Peritendinous or intrabursal corticosteroid injections can be used for the symptomatic treatment of greater trochanteric pain syndrome and anterior iliopsoas impingement. In past decades, the role of interventional radiology has rapidly increased in metastatic disease, thanks to the development of many ablative techniques...

The diffusion of imaging has determined an increased discovery of small renal masses (SRMs). Recent publications have been reviewed to present the state of the art in the management of SRMs and to try to foresee the next steps in this challenging condition. The role of percutaneous biopsies is expanding, since management algorithms include also active surveillance and ablative therapies. However up to 30% of biopsies fail to provide histological diagnosis and there is the risk of under-evaluating high-grade tumors...

OBJECTIVE AND METHOD: To focus on indications and results of ablative treatments (cyoablation, radiofrequency) for small renal masses, a bibliographic research was conducted in MedLine database using terms of "ablative treatment", "cryotherapy", "radiofrequency", "kidney cancer", "renal cell carcinoma". Sixty-four articles were selected. RESULTS: Carcinologic outcomes seem to be better with cryoablation than with radiofrequency. Available results have to be balanced according to surgical approach, teams' experience and duration of follow-up...

Cryoplasty may reduce the incidence of post-angioplasty restenosis in peripheral atherosclerotic arteries. Our study is looking to investigate the mid-term effects (4 weeks) of an FDA-approved cryoplasty catheter (PolarCath(®), Boston Scientific) compared to a conventional angioplasty catheter using a hypercholesterolemic rabbit model of arterial restenosis based on diet plus vessel injury. Thirty-six normolipidemic, 3-month old male New Zealand White rabbits were used. Balloon angioplasty was performed on left external iliac arteries on day 1...
