Radiofrequency ablation and microwave ablation are established treatment modalities for smaller (<3 cm) or isolated hepatic tumors. Transthoracic ablation of hepatic dome lesions is 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 lesion after induction of artificial pneumothorax. This involved the use of general anesthesia and insertion 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 local recurrence. The combined techniques of one lung ventilation and artificial pneumothorax enabled a safe and accurate transthoracic targeting of the hepatic dome lesion.
