6. Platelet count ≤ 50 × 109/L.
7. Patients with uncorrectable coagulopathy at time of screening based on investigator judgement. Severe blood coagulation dysfunction (bleeding tendency, prothrombin time \[PT\] was greater than normal control for 3\~5 seconds, platelet count \[PLT\] was less than 50x109/L, and the international normalized ratio \[INR\] was greater than 1.5).
8. Patient with renal failure and on renal dialysis.
9. Scheduled concurrent procedure other than MW ablation in the liver.
