|Official Title:||Clinical Trial Protocol for Therapeutic MRI-guided High Intensity Focused Ultrasound Ablation of Uterine Fibroids in a 3T MRI Scanner|
|Study Start Date :||January 2010|
|Actual Primary Completion Date :||July 2011|
|Actual Study Completion Date :||July 2011|
Experimental: Treated leiomyomas
Pre- or peri-menopausal women with symptomatic uterine fibroids who desire a uterine sparing procedure are treated with the Philips MR-guided HIFU system. Patients must have completed child bearing prior to enrolling in this study.
Device: Philips MR-guided HIFU system
HIFU is the use of focused ultrasound energy to penetrate through soft tissue and causes localized high temperatures (55°C to 70°C) for a few seconds within the target producing well defined regions of protein denaturation, irreversible cell damage, and coagulative necrosis.
- Safety of HIFU for treatment of the uterine fibroids as determined by adverse event reporting. [ Time Frame: 30 days after treatment ]Number of adverse events reported in the study divided by the total number of treated subjects.
- Technical efficacy of HIFU for treatment of uterine fibroids as assessed by a change in the Symptom Severity Score [ Time Frame: 30 days after treatment ]Mean absolute change in the Symptom Severity Score (SSS) of the uterine Fibroid Symptoms Quality of Life questionnaire from baseline to 30 days after treatment.
- Change in Quality of Life Scores [ Time Frame: 30 days after treatment ]Mean absolute score change in the Quality of Life questionnaire from baseline to 30 days after treatment.
- Pain score [ Time Frame: 72 hours after treatment ]Mean Visual Analog Score (VAS) for pain 72 hours after treatment.
- Timeframe before returning to daily activities [ Time Frame: 72 hours after treatment ]Mean timeframe for the patient to return to normal activity after treatment.
