Abstract

Objective: The objectives of this study were to evaluate the vascularization pattern of uterine myoma (UM) by ultrasonography using Superb Microvascular Imaging (SMI) and tissue stiffness elastography.

Method: A prospective and cross-sectional study was carried out between March 2020 and December 2022 among women with clinical and ultrasound diagnosis of UM who would subsequently undergo radiofrequency ablation. Ultrasound examination was performed using both transvaginal and transabdominal routes. UM vascularization pattern was assessed by power Doppler (PD) and SMI, while elastographic pattern was assessed by shear wave (SWE) and strain (STE). FIGO classification, location, and measurement of the largest UM were also described.

Results: A total of 21 women diagnosed with UM were evaluated. There was a predominance of nulliparous women and 20 women (95.2%) reported desire for pregnancy. Of the 18 women with abnormal uterine bleeding, 15 (83.3%) had abdominal cramping. As far as previous treatment, 7 (33.3%) had undergone myomectomy for other UM. The mean uterine and UM volumes were 341.9 cm3 (90-730) and 126.52 cm3 (6.0-430), respectively. There was a predominance of hypoechogenic lesions (90.5%). There was also preponderance of UM in the FIGO 2-5 classification (n = 9; 42.9%). Vascularization patter was mostly moderate (score 2) in 9 cases (42.9%). The majority of UM were considered to have intermediate stiffness (n = 10; 47.6%).

Conclusion: The majority of UM showed vascularization and moderate stiffness. A relationship was observed between the stiffness of the UM assessed by elastography and its FIGO classification.
