Abstract

STUDY OBJECTIVE: To evaluate a unique learning system for uterine artery embolization (UAE) and examine its feasibility and clinical outcomes for the treatment of symptomatic uterine leiomyomas and adenomyosis when performed by obstetrician-gynecologists in cooperation with interventional radiologists (IVRs). DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: One hundred seventy-three patients who underwent UAE for symptomatic leiomyomas and adenomyosis. INTERVENTIONS: We examined the medical records of patients who underwent UAE for symptomatic uterine leiomyomas and adenomyosis at our department between 2003 and 2012 using our learning system for UAE for obstetrician-gynecologists in cooperation with IVRs. The charts of all patients were reviewed, and data on etiologic factors, past medical history of leiomyomas and adenomyosis, symptoms, details of UAE, and clinical outcomes after UAE were extracted. MEASUREMENTS AND MAIN RESULTS: A total of 173 patients who underwent 177 UAEs were identified, including 4 patients who underwent embolization twice because of primary treatment failure or symptom recurrence. During the study period, 2 gynecologists successfully acquired endovascular skills. The technical success rate was 97.7% (174 of 177). The duration of fluoroscopy in procedures performed by obstetrician-gynecologists who acquired endovascular skills was not significantly different from that in procedures performed by IVRs at our institution; however, this duration was significantly longer in procedures performed by obstetrician-gynecologists who did not have sufficient experience with our learning protocol for UAE because of inadequate live observation of UAEs performed by skilled IVRs. Complications that necessitated discontinuation of the procedure occurred in 2.3% of cases (4 of 177). The clinical outcomes were similar to those reported in previous studies. Adverse events after UAE included myeloid passages in 7.0% (11 of 158), infections in 2.5% (4 of 158), vaginal discharge in 2.5% of patients with leiomyomas (4 of 158), and vaginal discharge in 7.1% of patients with adenomyosis (1 of 14). All the adverse events were adequately treated by the obstetrician-gynecologists themselves. The timing of hysterectomy due to complications or recurrence of symptoms after UAE varied widely. CONCLUSION: UAE performed by obstetrician-gynecologists in cooperation with radiologists can be achieved safely and successfully with acceptable clinical outcomes. Live observation of the procedure performed by skilled IVRs is essential to improving the skills and reducing the fluoroscopic time of obstetrician-gynecologists.
