Combined utility of one lung ventilation and artificial pneumothorax in thermal ablation of hepatic dome tumor: a technical note

Özet

Radiofrequency ablation and microwave ablation are established treatment modalities forsmaller (<3 cm) or isolated hepatic tumors. Transthoracic ablation of hepatic dome lesionsis a well described technique. We report the use of one lung ventilation to facilitate the successful percutaneous transthoracic microwave ablation of a segment 8 hepatic dome lesionafter induction of artificial pneumothorax. This involved the use of general anesthesia andinsertion of a double lumen endotracheal tube to allow isolated ventilation of one lung, followed by creation of an artificial pneumothorax under computed tomography (CT) guidance.Complete ablation of the lesion was confirmed on CT liver at 1 and 7 months with no localrecurrence. The combined techniques of one lung ventilation and artificial pneumothoraxenabled a safe and accurate transthoracic targeting of the hepatic dome lesion.
