Background High‐frequency jet ventilation is necessary to reduce organ movements during stereotactic liver ablation. However, post‐operative hypertensive episodes especially following irreversible electroporation ablation compared with microwave ablation initiated this study. The hypothesis was that hypertensive episodes could be related to ventilation or ablation method. Methods The aim of this retrospective study was to assess the proportion of patients with hypertensive events during recovery following liver ablation under general anaesthesia and to analyse the relation to ventilation and ablation technique. A medical chart review of 134 patients undergoing either high‐frequency jet ventilation and microwave ablation (n = 45), high‐frequency jet ventilation and irreversible electroporation (n = 44), or conventional ventilation and microwave ablation (n = 45) was performed. The proportion of patients with at least one episode of systolic arterial pressure 140‐160, 160‐180 or >180 mmHg during early recovery and the impact of ventilation method was studied. Results Out of 134 patients, 100, 75 and 34 patients had at least one episode of mild, moderate and severe hypertension. Microwave ablation, as well as high frequency jet ventilation, was associated with an increased odds ratio for post‐operative hypertension. The proportion of patients with at least one severe hypertensive event was 18/45, 9/44 and 7/45, respectively. Conclusion Both ventilation and ablation technique had an impact on post‐operative hypertensive episodes. The microwave ablation/high‐frequency jet ventilation combination increased the risk as compared with irreversible electroporation/high‐frequency jet ventilation and microwave ablation/conventional ventilation.
