Results after Endovascular Uterine Artery Embolization in the Treatment of Symptomatic Leiomyoma

Background: Purpose: to evaluate fibroid size using ultrasonography (US) and magnetic resonance imaging (MRI) after uterine arteries embolization (UAE) of leiomyoma.

Methods and Materials: UAE was performed through femoral access and transradial access in 1,025 patients. The size of particles depended on uterine arteries.

Case Results: The moderate reduction of leiomyoma's size was observed in 1 month after UAE. Decrease of fibroid size determined by US: 18.4%, by MRI: 17.3%, in 1 month. Following reduction of fibroid's size was determined in 3 months by US: 41%, by MRI: 42.7%; in 6 months by US: 58.4%, by MRI: 59.3%; in 12 months by US: 70.8%, by MRI: 72.7%. Doppler US-control showed blood flow decrease during first month after UAE, in 3 months blood flow data were restored in uterine arteries.

Discussion Conclusion: UAE is an effective, minimal-invasive kind of leiomyoma's treatment. MRI and US are the modalities that can accurately estimate fibroid's changes and blood flow in uterine arteries. The tendency of fibroid's shrinkage after UAE is well defined in the period from 1 month to 12 months.
