title: [Ultrasound-guided microwave ablation with artificial pleural effusion for liver tumor adjacent to  diaphragmatic dome].
abstract: To explore the value of ultrasound-guided microwave ablation with artificial pleural effusion for liver tumor adjacent to diaphragmatic dome.  Methods: A total of 34 patients with liver tumors located at diaphragmatic dome in Hunan Provincial Tumor Hospital were recruited from January 2014 to October 2015. The number of lesions ≤3 or lesion diameter ≤5 cm was in line with the microwave ablation indications. B ultrasound-guided microwave ablation for the liver tumors was undertaken after the artificial pleural effusion being established. 3-4 weeks later after the microwave ablation, all patients were imaged with enhance CT or MRI. The effect of ablation and the complications were evaluated.  Results: There were 49 lesions in 34 patients, including 30 cases (88.2%) of complete ablation (CA), 3 cases (8.8%) of partial ablation (PA) and one case with new lesions after ablation (2.9%). Thirty-four patients had (1 580±230.7) mL of pleural effusion volume, while one case had bloody pleural effusion. One case had a diaphragmatic thermal injury, and one case had a biliary tumor infection. All of them showed remission after symptomatic treatment.   Conclusion: Combination of ultrasound-guided microwave ablation with artificial pleural effusion is a safe and effective therapy for liver tumor adjacent to diaphragmatic dome.
