Tumor-induced osteomalacia (TIO) is a debilitating paraneoplastic condition caused by small phosphaturic mesenchymal tumors (PMTs) that secrete large amounts of the phosphate- and vitamin D-regulating hormone, FGF23. Tumor removal results in cure. However, due to high perioperative comorbidity, either from tumor location or host factors, surgery is sometimes not an option. Tumor destruction via cryoablation may be an effective option for inoperable PMTs. Three subjects with a confirmed diagnosis of TIO were studied...

BACKGROUND: Cryoablation for AVNRT is associated with higher recurrence rates than radiofrequency ablation(RF). Junctional tachycardia marks procedural success with RF, but no such indicator exists for cryoablation. OBJECTIVE: To determine the impact of voltage mapping plus longer ablation lesions on mid-term success of cryoablation for children with AVNRT. METHODS: A single-center retrospective analysis was performed of pediatric patients with AVNRT who underwent cryoablation from 2011-2015...

AIM: To evaluate the long-term outcome of catheter ablation of atrial fibrillation (AF) facilitated by preprocedural three-dimensional (3-D) transesophageal echocardiography. METHODS: In 50 patients, 3D transesophageal echocardiography (3D TEE) was performed immediately prior to an ablation procedure (paroxysmal AF: 30 patients, persistent AF: 20 patients). The images were available throughout the ablation procedure. Two different ablation strategies were used. In most of the patients with paroxysmal AF, the cryoablation technique was used (Arctic Front Balloon, CryoCath Technologies/Medtronic; group A2)...

Partial nephrectomy is the treatment of choice for small renal cell carcinoma (RCC) from the perspective of cancer management and renal function. However, when patients with RCC are of advanced age, exhibit severe comorbidities, including cardiovascular and pulmonary diseases, or have hereditary RCC, ablative therapies, including radiofrequency ablation (RFA) and cryoablation are useful treatment options. In the present study, the clinical outcomes of percutaneous RFA for treating small RCC were evaluated. Between December 2005 and March 2015, 40 patients (41 renal tumors in total) underwent RFA and a total of 50 sessions of RFA were performed...

Pelvic neuralgias frequently cause severe pain and may have associated bladder, bowel, or sexual dysfunctions which also impact quality of life. This article explores the etiology, epidemiology, presentation and treatment of common causes of neurogenic pelvic pain, including neuralgia of the border nerves (ilioinguinal, iliohypogastric, and genitofemoral), pudendal neuralgia, clunealgia, sacral radiculopathies caused by Tarlov cysts, and cauda equina syndrome. Treatment of pelvic neuralgia includes conservative measures such as pelvic physical therapy, lifestyle modification, and medications with escalation to more invasive and novel treatments such as nerve blocks, radiofrequency ablation, cryoablation, neuromodulation and neurectomy/neurolysis if conservative treatments are ineffective...

OBJECTIVE: Image-guided thermal ablation is a minimally invasive treatment option for patients with primary and secondary pulmonary malignancies. Modalities include radiofrequency ablation, microwave ablation, and cryoablation. CONCLUSION: Although no large randomized studies exist comparing ablation to surgery or radiotherapy, numerous studies have reported safety and efficacy for the treatment of both primary and metastatic disease in select patients. Future studies will refine patient selection, procedural technique, and assessment for local recurrence and will evaluate long-term survival...

Catheter ablation has become a standard technique for the treatment of atrial fibrillation. Pulmonary vein isolation (PVI) is the most important component of catheter ablation of atrial fibrillation. Radiofrequency (RF) ablation and balloon cryoablation can be used to achieve PVI. This review examines the biophysics and clinical efficacy of balloon cryoablation and discusses the potential advantages and disadvantages compared to RF ablation.

Qi Zhang, Gaojun Teng
Colorectal liver metastasis (CRLM) is one of the most difficult and key points in the treatment of colorectal cancer. Approximately 50% to 60% of patients diagnosed as colorectal cancer develops metastasis, and 80% to 90% of CRLM is unresectable. Surgical resection is the first-line treatment for CRLM, while it is only suitable for about 15% patients. Systemic chemotherapy can prolong the survival of CRLM patients, however, a part of CRLM patients are resistant to chemotherapy. With the development of technology and the update of clinical evidence, individual therapy with target drugs and multidisciplinary treatment (MDT) have became a tendency, and minimally invasive interventional therapy has gained more acceptance in the MDT mode of the treatment for CRLM...
