Abnormal uterine bleeding successfully treated via ultrasound-guided microwave ablation of uterine myoma lesions: Three case reports

Figure 1 Transvaginal ultrasound tomography. A: The schema for this procedure. Transvaginal ultrasound tomography was used to identify the feeding vessels of the uterine myomas via the color Doppler method. Using a needle-shaped deep coagulation electrode, the feeding vessels were directly ablated with microwaves at 2.45 GHz; B: Intraoperative transvaginal ultrasound tomography. Transvaginal ultrasound tomography using the color Doppler method was performed to identify the feeding vessels to the uterine myomas (arrow); C: A transvaginal ultrasound-guided microwave ablation of the feeding vessels to the uterine myomas using a needle-shaped deep coagulation electrode is depicted as a hyperechoic area (arrows).

Figure 2 Magnetic resonance imaging examination of the pelvis of before the procedure. Magnetic resonance imaging examination of the pelvis of before the procedure. A: Case 1; Sagittal T2-weighted image showed a 65 mm solid mass; B: Case 2; Sagittal T2-weighted image showed a 35 mm solid mass; C: Case 3; Sagittal T2-weighted image showed a 22 mm and 15 mm solid mass.

Figure 3 Magnetic resonance imaging examination of the pelvis of post the procedure. A: Case 1; The uterine myoma [International Federation of Gynecology and Obstetrics (FIGO) classification system 5] reduced from 65 mm to 27 mm by postoperative month 3; B: Case 2; The uterine myomas (FIGO classification system 5) reduced from 35 mm to 20 mm by postoperative month 3; C: Case 3; The uterine myomas (FIGO classification system 5) reduced from 22 mm and 15 mm to 15 mm and 13 mm by postoperative month 3.s
