PURPOSE: Uterine artery embolization (UAE) is an emerging treatment for symptomatic uterine @entity5 . This study was performed to evaluate the periprocedural results of the UAE procedure and identify risk factors for technical failure, fever after UAE, @entity158 , and other complications. MATERIALS AND METHODS: As part of a multicenter, randomized trial to compare UAE versus hysterectomy in @entity1 with symptomatic uterine @entity5 , 81 @entity1 underwent UAE. Univariate and multivariate analyses were used to identify predictors for technical failure, @entity221 as defined by the Society of Interventional Radiology (SIR), and @entity158 scores. RESULTS: The technical failure rate according to SIR guidelines was 5.3% (95% CI, 2.3%-10.1%). The procedural failure rate was 17.3% (95% CI, 9.8%-27.3%). Bilateral failure occurred in four of 81 @entity1 and unilateral failure occurred in 10 of 81 @entity1 . Technical failure occurred mainly as a result of difficult anatomy (3.7%) or absence of the uterine artery (3.1%). The overall complication rates were 28.4% during the @entity1 ' hospital stay and 60.5% for the 6 weeks after discharge. The risk of technical failure was found to increase in the presence of a single @entity5 (odds ratio [OR], 6.21; 95% CI, 1.65-23.41; P = .007) and/or a small uterine volume (<500 cm(3); OR, 10.8; 95% CI, 1.25-93.36; P = .03). The amount of embolization material was associated with the onset of fever after UAE (OR, 2.05; 95% CI, 1.09-3.87; P = .027), major complications (OR, 5.68; 95% CI, 2.05-15.75; P = .001), and high @entity158 scores (OR, 1.97; 95% CI, 1.08-3.58; P = .027). CONCLUSIONS: The procedural failure rate for UAE was higher than those reported by others, mainly as a result of difficult anatomy and absence of a uterine artery in some cases. The risk of procedural failure was increased for @entity1 with single @entity5 and/or small uterine volumes. A clear dose-effect response was revealed between the amount of embolization material used and the risk for @entity221 , and severe @entity158 .
