The use of electroanatomical mapping can facilitate the identification of the ideal cryoablation site by providing a three-dimensional map of the earliest activation site. Combined use of the cryoablation technology with electroanatomical mapping can further increase the precision and safety of the procedure by applying test applications at a lower energy level.

Transradial access (TRA) has been associated with improved post-procedure hemostasis and patient satisfaction, and decreased hemorrhagic complications, sedation requirements, recovery times, and procedure-related costs when compared with traditional transfemoral catheterization. Supine TRA has been described for the treatment of myocardial infarctions, aortoiliac and femoropopliteal stenoses, and a variety of neoplasms. This original research describes prone transradial catheterization to facilitate combined single-session transarterial embolization and percutaneous cryoablation of solid neoplasms from a posterior approach without repositioning...

We report a case of recurrent renal cancer in the autografted kidney, treated with percutaneous cryoablation. A 59-year-old man who had bilateral renal tumors underwent radical left nephrectomy, ex vivo right partial nephrectomy and auto-transplantation at the right ileal fossa in our hospital 11 years ago. Histopathological examination showed clear cell renal cell carcinoma in bilateral kidneys (pT1bN0M0). He had been followed at another hospital without tumor recurrence for 11 years. In 2014, an enhanced CT scan revealed a renal tumor with a diameter of two centimeters in the autografted kidney, which was thought to be a recurrence of the initial renal cancer...

INTRODUCTION: Due to spinal instability and compressive neurologic deficits surgical management is sometimes necessary in patients with metastatic spinal lesions. However, in some cases open surgery is not possible and minimally invasive procedures, like cryoablation, are needed. The aim of the current study was to investigate whether a miniature cryoprobe provides adequate tissue cooling in vertebrae and to evaluate the direct impact of cryosurgery on vertebral body stability. MATERIALS AND METHODS: Twelve thoracic vertebral bodies were harvested from fresh cadavers...

The number of new cases of renal cell carcinoma has been steadily increasing since the 1960s, reaching 62,000 and 89,000 annually in the United States and Europe, respectively, in 2016. The current standard of care for early-stage disease is nephron-sparing surgery, which has a demonstrated long-term disease-free survival and an acceptable safety profile. Technical developments (thin, powerful probes and real-time image guidance systems) have allowed image-guided percutaneous ablation to become a viable option for stage I renal cell carcinoma...

Ablative treatments currently represent the first-line option for the treatment of early stage unresectable hepatocellular carcinoma (HCC). Furthermore, they are effective as bridging/downstaging therapies before orthotopic liver transplantation. Contraindications based on size, number, and location of nodules are quite variable in literature and strictly dependent on local expertise. Among ablative therapies, radiofrequency ablation (RFA) has gained a pivotal role due to its efficacy, with a reported 5-year survival rate of 40%-70%, and safety...

OBJECTIVE: We report nine consecutive percutaneous image-guided cryoablation procedures of head and neck tumors in seven patients (four men and three women; mean age, 68 years; age range, 50-78 years). Ablation of the entire tumor for local control or ablation of a region of tumor for pain relief or preservation of function was achieved in eight of nine procedures. One patient experienced intraprocedural bradycardia, and another developed a neopharyngeal abscess. There were no deaths, permanent neurologic or functional deficits, vascular complications, or adverse cosmetic sequelae due to the procedures...

BACKGROUND: Several systems for MRI/TRUS fusion-guided biopsy of the prostate are commercially available. Many studies have shown superiority of fusion systems for tumor detection and diagnostic quality compared to random biopsy. The benefit of fusion systems in focal therapy of prostate cancer (PC) is less clear. OBJECTIVES: Critical considerations of fusion systems for planning and monitoring of focal therapy of PC were investigated. MATERIALS AND METHODS: A systematic literature review of available fusion systems for the period 2013-5/2016 was performed...

Percutaneous imaging-guided cryoablation (PICA) is a recently developed technique, which applies extreme hypothermia to destroy tumours under close imaging surveillance. It is minimally invasive, safe, repeatable, and does not interrupt or compromise other oncologic therapies. It presents several advantages over more established heat-based thermal ablation techniques (e.g. radiofrequency ablation; RFA) including intrinsic analgesic properties, superior monitoring capability on multi-modal imaging, ability to treat larger tumours, and preservation of tissue collagenous architecture...

OBJECTIVES: Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI) dependent atrial flutter (AFL). We aimed to study whether different CTI morphologies had different impacts on procedural success for CRYO and RF. DESIGN: This study randomized 153 patients with CTI-dependent AFL (median age 65 years; range 34-82) to RF or CRYO (78 CRYO; 75 RF). Biplane angiography (RAO 30º and LAO 60º) was done before the ablation procedure and isthmuses were classified as straight (n = 81), concave (n = 43), or pouch-like (n = 29)...
