Risk Factors for Residual Unablated Tumour Following CT-Guided Percutaneous Renal Cryoablation: Lessons from the EuRECA Registry.
Cardiovasc Intervent Radiol
January 2025
Department of Radiology, Southampton University Hospitals, Southampton, UK.
Objective: To assess tumour factors that reduce primary technical efficacy (PTE) from CT-guided renal cryoablation.
Methods: Patients were taken from the EuRECA registry between December 2014 and November 2020. To focus on tumour factors rather than individual technique, this study was limited to cases using CT and excluded procedures using cone beam, US, MRI, or laparoscopy.

Article Synopsis
- Ventricular arrhythmias (VAs) like ventricular tachycardia and ventricular fibrillation pose serious treatment challenges with high risks of morbidity and mortality, particularly in patients unresponsive to standard therapies.
- This study examined the safety and effectiveness of CT-guided left stellate ganglion cryoneurolysis (SGC) in these refractory VA patients across two hospitals, involving 17 patients with a notable reduction in defibrillation events after the procedure.
- Results showed that 82% of patients were free from defibrillation 24 hours post-procedure, with no serious adverse effects reported, highlighting the potential of SGC as a beneficial alternative treatment strategy for refractory VAs.
Evaluating the Accuracy and Efficiency of Imaging Modalities in Guiding Ablation for Metastatic Spinal Column Tumors: A Systematic Review.
Cancers (Basel)

Department of Neurotraumatology, Semmelweis University, 1081 Budapest, Hungary.
Background/objectives: Spinal metastases are a frequent and serious complication in cancer patients, often causing severe pain, instability, and neurological deficits. Thermal ablation techniques such as radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation (CA) have emerged as minimally invasive treatments. These techniques rely on precise imaging guidance to effectively target lesions while minimizing complications.
