EFFICACY OF MICROWAVE ABLATION FOR HEPATIC LESIONS USING MULTI-DETECTOR COMPUTED TOMOGRAPHY

Abstract

Background: Hepatic lesions, including primary hepatocellular carcinoma and metastatic liver tumors, are a significant cause of morbidity and mortality worldwide. Microwave ablation (MWA) has emerged as a minimally invasive treatment option, while multidetector computed tomography (MDCT) plays a key role in evaluating treatment response. Objective: To assess the efficacy of microwave ablation for hepatic lesions using MDCT Methods: A descriptive cross-sectional study was conducted on 80 patients with hepatic lesions undergoing MWA. Pre- and post-procedural MDCT imaging was performed using a standardized multiphasic protocol. Data collected included lesion characteristics, procedural parameters, and follow-up findings. Treatment response was categorized as complete response, partial response, or stable disease. Statistical analysis was carried out using SPSS. Descriptive statistics, independent samples t-test, Pearson’s chi-square test and binary logistic regression were employed. Results: The mean age was 58.56 ± 10.39 years with equal gender distribution. The mean lesion size was 32.34 ± 10.86 mm. Complete response was achieved in 81.3% of patients, while partial response and stable disease were observed in 16.3% and 3.8%, respectively. Local tumor progression occurred in 6.3% of cases. Patients without progression had significantly smaller lesions, larger ablation zones, and wider safety margins (p < 0.001). Most patients (80%) experienced no complications, with only 5% having major complications. Conclusion: Microwave ablation is a safe and effective treatment for hepatic lesions. MDCT provides reliable assessment of treatment response, and outcomes are strongly influenced by lesion size and adequacy of ablation margins.
