Primary Outcome Measures:
  • Number of Participants With Fibroid Devascularization Measured by Contrast Enhanced Magnetic Resonance Imaging (MRI) [ Time Frame: 24-hours post study procedure ]
    MRI uses a large circular magnet and radio waves to generate signals from atoms in the body. These signals are used to construct images of internal structures. Injection of contrast through an IV is done during the test to enhance the view of the uterus. Contrast enhanced MRI was used as a test in this study to verify if blood supply to the fibroids was blocked or interrupted (devascularization).


Secondary Outcome Measures:
  • Visual Analog Scale (VAS) Maximum Level of Nausea [ Time Frame: 24 hours after study procedure ]
    Maximum level of nausea was measured using the Visual Analog Scale(VAS). The patient is presented with a picture of a straight line that is 0-10 cm long. The left side of the line (0 cm) represents 'no nausea' and the right side (10cm) of the line represents 'worst nausea imaginable'. The patient is asked to place a mark on the line that represents their level of nausea. For example, a reading of 10cm = worst nausea imaginable.

  • Visual Analog Scale (VAS) Maximum Level of Pain [ Time Frame: 24 hours after study procedure ]
    Maximum level of pain was measured using the Visual Analog Scale(VAS). The patient is presented with a picture of a straight line that is 0-10 cm long. The left side of the line (0 cm) represents 'no pain' and the right side (10cm) of the line represents 'worst imaginable'. The patient is asked to place a mark on the line that represents their level of pain. For example, a reading of 10cm = worst imaginable pain.

  • Fluoroscopy Time [ Time Frame: During the study procedure (measured in minutes) ]
    Fluoroscopy is the method that provides real-time X ray imaging used for guiding a variety of diagnostic and interventional procedures. Fluoroscopy time is described as the amount of time the patient underwent fluoroscopy.

  • Procedure Time [ Time Frame: During the study procedure (measured in minutes) ]
    Procedure time is the time in minutes of the first arterial puncture to time of hemostasis (stopping bleeding)

  • Any Adverse Events That the Participant Experienced [ Time Frame: During the hospitalization stay post UFE ]
    Summary of investigator reported adverse events and adverse device effects, including all serious adverse events and unanticipated adverse device effects. Adverse events were collected systematically, meaning they were collected during the participant's follow-up visit, during telephone contacts, or during medical record review.

  • Uterine Fibroid Symptom Quality of Life Questionaire (UFS-QOL) Score [ Time Frame: Baseline ]

    The UFS-QoL asks the subjects feelings and experiences regarding the impact of uterine fibroid symptoms and experiences during the previous 3 months.

    The scores are added and the final total scores range from 0-100. The lowest actual raw score=8, the highest raw score=40, the possible raw score range=32. A formula is then used to transform the value(actual raw score-lowest possible raw score divided by possible raw score range x100). Higher symptom score values are indicative of greater symptom severity or bother and lower scores indicate minimal symptom severity (high scores = bad)


  • Uterine Fibroid Symptom Quality of Life Questionaire (UFS-QOL) Score [ Time Frame: 3-months ]

    The UFS-QoL asks the subjects feelings and experiences regarding the impact of uterine fibroid symptoms and experiences during the previous 3 months.

    The scores are added and the final total scores range from 0-100. The lowest actual raw score=8, the highest raw score=40, the possible raw score range=32. A formula is then used to transform the value(actual raw score-lowest possible raw score divided by possible raw score range x100). Higher symptom score values are indicative of greater symptom severity or bother and lower scores indicate minimal symptom severity (high scores = bad)


  • Uterine Fibroid Symptom Quality of Life Questionaire (UFS-QOL) Score [ Time Frame: 12 months ]

    The UFS-QoL asks the subjects feelings and experiences regarding the impact of uterine fibroid symptoms and experiences during the previous 3 months.

    The scores are added and the final total scores range from 0-100.The lowest actual raw score=8, the highest raw score=40, the possible raw score range=32. A formula is then used to transform the value(actual raw score-lowest possible raw score divided by possible raw score range x100). Higher symptom score values are indicative of greater symptom severity or bother and lower scores indicate minimal symptom severity (high scores = bad).


  • Health Related Quality of Life (HRQL)Subscores [ Time Frame: Baseline ]

    The HRQL subscales (concern, activities, energy/mood, control, self-conscious, and sexual function were collected from the UFS-QoL.

    Each individual subscale is added. HRQL Total (sum of 6 subscales); lowest possible raw score = 29, highest possible raw score=145. A formula is used to transform the HRQL raw scores (Highest possible score-actual raw score divided by possible raw score range x 100). Higher scores are indicative of a better HRQL and lower scores indicate a worse HRQL (High=good). The value reported for this measure is the average of all participants scores.


  • Health Related Quality of Life Subscores [ Time Frame: 3 months ]

    The HRQL subscales (concern, activities, energy/mood, control, self-conscious, and sexual function were collected from the UFS-QoL.

    Each individual subscale is added. HRQL Total (sum of 6 subscales); lowest possible raw score = 29, highest possible raw score=145. A formula is used to transform the HRQL raw scores (Highest possible score-actual raw score divided by possible raw score range x 100). Higher scores are indicative of a better HRQL and lower scores indicate a worse HRQL (High=good). The value reported for this measure is the average of all participants scores.


  • Health Related Quality of Life Subscores [ Time Frame: 12 months ]

    The HRQL subscales (concern, activities, energy/mood, control, self-conscious, and sexual function were collected from the UFS-QoL.

Arms Assigned Interventions
Experimental: Arm 1 Procedure: Uterine Fibroid Embolization (UFE)
Uterine Fibroid Embolization is used in treating Uterine Fibroids. The procedure involves injecting embolization particles into the fibroid via the uterine artery which causes the fibroid to shrink or subside. Patients are usually released from the hospital the day after the procedure.
Device: Contour SE™ Microspheres
Polyvinyl alcohol Microsphere embolization devices intended to provide targeted vascular occlusion or reduction of blood flow upon selective placement and are currently marketed for use in hypervascular tumors, including leiomyoma uteri and arteriovenous malformations
Active Comparator: Arm 2 Procedure: Uterine Fibroid Embolization (UFE)
Uterine Fibroid Embolization is used in treating Uterine Fibroids. The procedure involves injecting embolization particles into the fibroid via the uterine artery which causes the fibroid to shrink or subside. Patients are usually released from the hospital the day after the procedure.
Device: Embosphere® Microspheres
Biocompatible, hydrophilic, nonresorbable, microspheres used in the embolization of arteriovenous malformations, hypervascular tumors, and symptomatic uterine fibroids.

Detailed Description:
The purpose of this prospective randomized single-center study is to demonstrate comparability using Contour SE™ Microspheres (700-900µ and 900-1200µ) using a near stasis endpoint and Embosphere® Microspheres (500-700µ) using a "prune tree" endpoint for achieving post UFE fibroid devascularization in women with symptomatic uterine fibroids. The study will demonstrate (with the use of contrast enhanced Magnetic Resonance Imaging (MRI) at baseline and 24-hours post embolization) that uterine fibroids can successfully be devascularized using the embolization protocols. Contrast enhanced MRI will be performed at baseline, 24-hours, and 3-months post UFE. The subjects will be followed through 12-months post UFE and change from baseline in symptom severity (Quality of Life (QoL) Questionnaire) will be assessed at 3 months and 12 months.
