Purpose Percutaneous renal mass cryoablation is generally performed utilizing CT guidance. Electromagnetic navigation devices offer the potential advantage of reduced number of instrument adjustments and thus less imaging. The aim of our study was to determine whether the Veran ig4 Delivery System reduces procedure time and/or radiation dose during CT-guided percutaneous renal cryoablation of solid renal tumors. Materials and Methods Retrospective analysis of 50 cases of renal cryoablation were performed at our institution. Cases were divided between those with Veran ig4 guidance those without. Procedure times were recorded from the CT images beginning with the time of the first scan to the time of the final scan. Total procedure radiation dose was recorded from the total dose length product (DLP). Patient ages ranged from 34-87 years with renal masses ranging in size from 0.9 cm up to 4 cm. Results Our findings showed a mean procedure time of 82.25 minutes and a DLP of 3955.86 with the Veran ig4 guidance system. The procedures without the guidance system showed a mean procedure time of 82.07 minutes and a DLP of 3101.96. The procedure times were not statistically siginificant. Conclusion Usage of the Veran ig4 guidance system is an evolutionary idea in improving renal cryoablation procedures. Although our findings did not show a statistical significance in procedure times, we believe this may be attributed to the learning curve associated with the guidance system. Furthermore, procedure times may be slightly increased with the Veran ig4 guidance system due to treatment of larger and more difficult lesions. We believe our findings warrant further investigation into using this novel technique for renal cryoablation.
