There is logical hesitation among clinicians to pursue MWA in these decompensated patients for fear of worsening an already bleak prognosis, but there is limited evidence to justify this behavior.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Material and Methods:<\/jats:title>\n<jats:p>A retrospective review of HCC treated with percutaneous MWA at a single center was performed. 18 patients who underwent CT-guided MWA with pre-existing diuretic-resistant ascites were identified. A control group of 29 patients who underwent CT-guided MWA without pre-existing diuretic-resistant ascites was identified, which was further narrowed to 18 patients after matching by Model for End-Stage Liver Disease-Sodium score and age. The effectiveness of treatment was compared between the two groups and evaluated by disease-free survival, residual disease, and overall survival over 36 months. Kaplan\u2013Meier curves plotting the survival function were constructed to compare these variables in both groups.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>MWA was successfully performed in all patients. The probability of survival at 1 year for the ascites and matched control groups were 0.778 and 1.00, respectively (<jats:italic>P<\/jats:italic> = 0.038). The probability of survival at 3 years for the ascites and matched control groups were 0.556 and 0.630, respectively (<jats:italic>P<\/jats:italic> = 0.237). There were no significant differences between residual disease and disease-free survival between the two groups at 1 or 3 years.<\/jats:p>\n<\/jats:sec>\n<jats:sec
