Purpose: To evaluate safety and efficacy of uterine artery embolization (UAE) for pedunculated subserosal (PS) leiomyomas. Materials and Methods: Of 1,069 patients who underwent UAE for symptomatic leiomyomas or adenomyosis from 2007 to 2016, 55 patients (mean age 40.3 y ± 4.8) with 66 PS leiomyomas (mean diameter 6.61 cm ± 2.04) were enrolled. Each PS leiomyoma was categorized into 1 of 2 groups: high-risk PS leiomyoma (stalk diameter < 25% of diameter of leiomyoma) and low-risk PS leiomyoma (stalk diameter 25%–50% of diameter of leiomyoma). MR imaging was performed 3 months after UAE. Rates of infarction and volume reduction were compared between PS leiomyomas and non-PS dominant leiomyomas and between high-risk and low-risk PS leiomyomas. Complications related to PS leiomyomas were assessed. Results: At a median follow-up of 96 days (range, 36–348 d) after UAE, none of the patients (0%) had complications related to PS leiomyomas, even among high-risk cases. Mean volume reductions of 38.2% and 38.4% were achieved for PS leiomyomas and non-PS dominant leiomyomas, respectively (P =.953). There were 3 (5.5%) minor adverse events, but none were related to PS leiomyoma. There was no significant difference in volume reduction and infarction rates between low-risk and high-risk PS leiomyomas. Conclusions: UAE is safe and effective in patients with PS leiomyomas even for high-risk cases (stalk diameter < 25% of diameter of leiomyoma). PS leiomyoma should not be considered a contraindication for UAE.
