Outpatient uterine artery embolization for symptomatic uterine fibroids: experience in 49 patients

To assess the feasibility of performing uterine artery embolization as an outpatient treatment for symptomatic uterine fibroids.

Forty-nine consecutive patients (mean age, 44.5 years; range, 28-54 years) underwent uterine artery embolization during a 12-month period. Embolization was performed with 350-500 microm polyvinyl alcohol particles (44 of 49) or Gelfoam pledgets (five of 49). At discharge, patients were given instructions regarding the constitutional symptoms to expect after embolization. A specific medication regimen consisting of prochlorperazine, ketorolac, meperidine, and hydrocodone was prescribed for relief of these symptoms. All patients were telephoned within 24 hours of discharge. During long-term follow-up, a questionnaire was administered to all patients to evaluate the periprocedural experience. Three-month clinical follow-up was available in 26 patients and 6-month imaging follow-up was available in 16 patients.

Fourteen patients presented with menorrhagia, six had bulk-related symptoms (abdominal distension, stress incontinence, pelvic pain), and 29 had both. Technical success for bilateral embolization was 98%. Forty-seven of 49 patients were discharged to home 6-8 hours after the procedure; two patients required overnight observation in an ambulatory unit (one because of postprocedure hypertension and one because of a late procedure completion time). At the first follow-up phone call, reported symptoms included pelvic pain/cramping in 83.7% (41 of 49), fatigue in 75.5% (37 of 49), nausea/vomiting in 46.9% (23 of 49), and a nonpurulent vaginal discharge in 18.4% (nine of 49). These symptoms were satisfactorily controlled with discharge medications in 48 of 49 patients. No patients returned to the hospital or visited an emergency room during the first 48 hours after discharge. Forty-six of 49 patients were satisfied with the decision for home discharge. The average uterine volume reduction in 16 patients with 6-month imaging follow-up was 47.5%; 88.5%, of patients (23 of 26) with 3-month clinical follow-up reported improvement or elimination of symptoms.

With defined telephone follow-up, staff availability, and a protocol designed to alleviate the postprocedure constitutional symptoms, uterine artery embolization is both safe and effective when performed as an outpatient procedure.
