Clinical Effectiveness of Microwave Ablation Using Starwave Microwave Generator for Hepatic Malignancies

Following the existing procedure of our institute, we aim to treat the tumor by applying up to 150W of microwaves within the tumor using a StarWave microwave generator and a 13-gauge antenna under fusion ultrasound guidance. If necessary, the antenna is reinserted 1-2 times to create sufficient ablation lesions until an echogenic band of 5-10mm is formed around the tumor and its periphery, implementing overlapping microwave ablation (MWA). Afterward, the antenna is removed while applying microwave energy to prevent bleeding.
