To evaluate the feasibility, safety and clinical efficacy of percutaneous microwave ablation (MVA) uterine leiomyoma. 13 leiomyoma in 10 patients were ablated by (MV). 11 tumors punctured under direct vision during operation 2 percutaneously US-guidance. Biopsy was performed before MVA. The tension tumor capsule increased progressively looked pale with prolongation MV emmission. After MVA, shrunk gradually became crimped. serosa at puncture site undamaged 9 burned due to short insertion needle antenna. On cross section view, firm yellowish, having well-defined borders. For single antenna application, zone ellipsoidal, size 2.7 × 2.8 2.6 cm 50 W 300 sec 5.1 3.5 4.0 60 sec. Complete coagulative necrosis observed light microscope HE stain. Percutaneous MVA: Hyperechogenicity noted immediately after emission which enlarged over time enveloped entire finally. CDFI showed no blood flow signal within Abdominal pain encountered alleviated cessation emission. discomfort disappeared spontaneously 12 hours requiring analgesia. No complication all patients. spherical enhancement on contrast-enhanced US Contrast-enhanced CT. Four months cystic tumor, shrank 80% volume. Patients' symptoms relieved significantly. US-guided MVA appears be a safe effective method for treatment myoma. It may become promising minimally invasive option
