Abstract：Objective: To explore the clinical value of using the CT screen drawing line method to guide the microwave ablation of percutaneous liver tumor. Methods: Thirty-nine cases of liver cancer patients(54 lesions, the average maximum diameter (2.6±1.3) cm) were enrolled. CT guided percutaneous microwave ablation was performed by CT screen drawing line plan. Real-time CT check after ablation was performed to observe and check whether the actual needle was corresponding to the plans. The success of screen wire guided puncture was evaluated. The complication and the recent therapy effect were analyzed. Results: The microwave ablation was successfully completed on the 54 lesions. Scattered small bubbles were seen in all lesions, in the 38 lesions with no iodine oil deposition, carbonized ablation railway lines were shown, which were consistent with plans. The completely melt rate was 94.4%(51/54), and partial residual rate was 5.6%(3/54). No severe tissue damage was found in surrounding important organs. Conclusion: It is worth promoting the use of screen drawing line to guide ablation needle puncture, which can ensure the complete ablation and ablation safety.
