Management of uterine artery embolization for fibroids as an outpatient procedure.

Purpose: To evaluate whether it is safe to perform uterine artery embolization (UAE) as an outpatient procedure.

Materials And Methods: This retrospective study was approved by the institutional review board and included 234 patients (age range, 24-58 years; mean age, 40.5 years) who underwent UAE as an outpatient procedure with polyvinyl alcohol particles between January 2007 and March 2008. Patients were given acid-suppressing drugs, nonsteroidal anti-inflammatory drugs, anti-histaminic drugs, and laxatives twice on the day before UAE and once on the morning of UAE. Pain score, rated from 0 to 10, was evaluated by using a numeric pain scale during UAE, after the procedure, at discharge, at the night of discharge, and on the following morning. The outcome of UAE was evaluated at 6 months by means of pelvic magnetic resonance imaging and clinical observation.

Results: The mean pain score was 0.9 during embolization, 2.5 4-8 hours after embolization, 0.9 at discharge, 1.1 the first night after discharge, and 0.7 the next morning. All patients were discharged from the hospital 4-8 hours after the procedure, with no overnight hospital admissions. At 6 months, 146 of 158 patients (92.4%) reported an improvement in menorrhagia, 39 of 44 (88.6%) reported an improvement in bulk symptoms, and 20 of 25 (80%) reported an improvement in pain. The volumes of the uterus and the dominant fibroid decreased 33.7% and 39.3%, respectively.

Conclusions: With acid-suppressing, anti-inflammatory, and anti-histaminic drugs started on the day before UAE, the procedure can be performed safely as an outpatient procedure.
