PURPOSE To review complications related to percutaneous renal tumor ablation. MATERIALS AND METHODS Prospectively collected data related to renal radiofrequency (RF) ablation and cryoablation procedures performed from May 2000 through November 2010 were reviewed. This included 573 renal ablation procedures performed in 533 patients to treat 633 tumors. A total of 254 RF ablation and 311 cryoa...

BACKGROUND Development of electroanatomical systems make it possible to perform ablations without the use of fluoroscopy. The aim of this study was to evaluate the efficacy and safety of cryoablation procedures without the use of fluoroscopy. METHODS The study group consisted of 45 patients (14 female; age 36 ± 15 years) treated with cryoablation using the EnSite electroanatomical system: 10 ...

Purpose: Renal cryoablation is an evolving nephron-sparing treatment alternative for select patients with small renal tumors. Initially described via either an open or percutaneous technique, renal cryoablation has been performed by a laparoscopic approach with promising results. We critically review the cumulative evidence available regarding this technique. Materials and Methods: A review of ...

Percutaneous cryoablation is a minimally invasive procedure for tumor destruction, which can potentially initiate or amplify antitumor immunity through the release of tumor-associated antigens. However, clinically efficacious immunity is lacking and regional recurrences are a limiting factor relative to surgical excision. To understand the mechanism of immune activation by cryoablation, compreh...

•Cryoablation of ER+, PR+, and HER2-invasive ductal carcinoma ?15 mm offers optimal local control.•Cryoablation is a feasible alternative to surgery in low-risk breast cancer.•Breast imaging at 6 months showed no residual or recurrent disease.•Breast MRI has the highest negative predictive value among modalities. BackgroundThe aim this study was evaluate feasibility cryoablation for early-stage...

BACKGROUND AND PURPOSE American Urological Association guidelines endorse partial nephrectomy as the preferred treatment for patients with small renal masses, while considering patients with significant comorbidities potential candidates for ablative therapy. We compared perioperative, renal functional, and oncologic outcomes of renal cryoablation and robot-assisted partial nephrectomy (RAPN) b...

INTRODUCTION A canine model was used to compare cryoablation and radiofrequency ablation (RFA) within the coronary sinus (CS) in the ability to create a transmural CS myocardial (Trans-CSM) lesion and risk of coronary artery stenosis. METHODS After CS and left circumflex (LCx) coronary angiography, an intravascular ultrasound (IVUS) probe was placed in LCx in 29 dogs. An irrigated RFA cathete...

PURPOSE We aimed to compare local and metastatic recurrence of small renal masses primarily treated by cryoablation or microwave ablation. MATERIALS AND METHODS The MEDLINE, CINAHL, and PUBMED databases were searched to review the treatment of small renal masses with cryoablation or microwave ablation. Fifty-one studies met the inclusion criteria. RESULTS Fifty-one studies representing 3950...

OBJECTIVES We sought to describe the early pediatric experience of transcatheter cryoablation, and identify whether specific arrhythmia substrates and/or ablation locations were particularly suited to cryoablation. BACKGROUND Radiofrequency (RF) ablation has become established therapy for pediatric tachyarrhythmias. However, challenges remain in terms of the safety and efficacy of RF ablation i...

BACKGROUND Radiofrequency (RF) catheter ablation has provided an effective method for treating drug-refractory symptomatic atrial fibrillation. Recently, a cryoablation balloon approach has also received approval. The purpose of this study was to compare RF catheter ablation to cryoablation for the treatment of atrial fibrillation with respect to safety, immediate efficacy, and effects on proce...
