“…Much less is known about cryoablation of cartilage, which is not used in the treatment of articular cartilage. However, cartilage damage related to cryoablation of bone lesions has been reported (22,23). The present results demonstrated that RF ablation and cryoablation resulted in cellular injury to chondrocytes, which is consistent with the effects of thermal ablation on cellular structures.…”

“…Third, the predicted in vivo ablation zone temperatures were not verified. As with all cryoablation technology to date, extrapolations must be made from benchtop isotherms to human procedures without real‐time knowledge of the effects of probe depth, tissue type, adjacent vessels, or time on the actual ablation zone temperatures .…”

Objective: This study evaluated the safety of percutaneous CT-guided cryoablation of the vagus nerve (percutaneous cryovagotomy) in participants with class I or class II obesity. Methods: The study was an open-label, single-group, prospective pilot investigation designed around safetyrelated stopping criteria. Twenty participants with 30 > BMI > 37 underwent percutaneous cryovagotomy with follow-up visits at day 7, 45, 90, and 180. Data related to adverse events, technical success, weight loss, quality of life, dietary intake, global impressions of hunger change, activity, and body composition were analyzed. Results: The procedural technical success rate was 100%. There were no adverse events in 19 participants who completed the trial. Ninety-five percent of patients reported decreased appetite following the procedure, and reductions in mean absolute weight and BMI were observed at all time points. The mean quality of life and activity scores improved from baseline to 6 months post procedure, and mean caloric intake and overall body fat decreased over the same period. Conclusions: Percutaneous CT-guided cryovagotomy is feasible and was tolerated without complications or adverse events in this cohort. Quantitative preliminary data from this pilot investigation inform the design of a larger prospective randomized clinical trial.

“…Iatrogenic injury to central and peripheral nerves is a known complication after thermal ablation (3,4). Osseous lesions are sometimes located in positions where effective cryoablation can compromise adjacent nerves.…”
