Description of intervention(s) / exposure
This research project has been designed to provide information on the safety and effectiveness of the Uterine Artery Embolisation (UAE) procedure for the treatment of endometriosis and will be used to determine if a larger study will be undertaken.

Uterine Artery Embolisation (UAE) is accepted in Australia to treat uterine leiomyomas (fibroids). There is also growing literature to support UAE for the treatment of symptomatic adenomyosis (a condition when the tissue that lines the uterus grows into the muscular wall of the uterus). Adenomyosis and endometriosis are both disorders of the endometrial tissue that lines the uterus.

UAE is a procedure where an embolic agent (a gel or glue) is placed in the uterine artery to limit the blood flow to areas of the uterus. It is a minimally invasive procedure performed by an Interventional Radiologist under image guidance. A small incision is made in the groin or the arm and a catheter (a long narrow tube) is placed in the artery and, under image guidance the catheter is directed to the artery to be treated. Once the catheter is in place the embolic agent is placed in the artery and the catheter is removed.

UAE is not approved to treat endometriosis. Therefore, it is an experimental treatment for endometriosis. This means that it must be tested to see if it is an effective treatment for endometriosis.

The procedure will only be done once to participants of this study. Embolisation of uterine arteries (bilateral) using particulate embolic (Boston Scientific Contour PVA Embolization particles). Volume used is dependent on the vessel size, ranging from 3ml-9ml.

The procedure duration will be around 60-90 minutes. The patients will be admitted overnight post procedure for monitoring and further care.

Adherence to the intervention will be done post procedure follow-up and monitoring, and clinical and medical report review.

Outcomes
Primary outcome [1] 332631 0
Safety assessed by the composite number of procedural and post procedural complications as defined by the 2017 Cardiovascular and Interventional Radiological Society of Europe (CIRSE) guidelines.

Risks of Uterine Artery Embolisation

• Hysterectomy
• Non-target embolization
• Contrast agent allergy
Timepoint [1] 332631 0
During procedure, pre-discharge and at six weeks, 3 months, 6 and 12 months through telephone follow-up. Participants should be free from procedural and post procedural complications.

Consultation with the study investigator, recording of SAEs and administration of the BSGE pelvic pain questionnaire will be at 6 weeks, 6 and 12 months post procedure.

Consultation with the referring gynaecology and fertility specialist will be at 3 and 12 months post procedure.

Data will be gathered from the medical procedure notes, follow-up and consultations notes via electronic and paper-based medical record.
Secondary outcome [1] 414156 0
1.Technical success of UAE as defined by visualisation of a significant reduction in perfusion via the uterine artery on angiography at the discretion of the proceduralist. Data will be gathered from the medical procedure notes via electronic medical record.

Timepoint [1] 414156 0
This will be assessed during and immediate after the procedure. Data will be gathered from the medical procedure notes via electronic medical record.
Secondary outcome [2] 414157 0
Any change in pelvic pain at 6 and 12 months as defined by an improvement in the British Society of Gynecologic Endoscopy (BSGE) pelvic pain questionnaire.
Timepoint [2] 414157 0
6 and 12 month post procedure through follow-up consultation. Data will be gathered from the British Society of Gynecologic Endoscopy (BSGE) pelvic pain questionnaire accomplished and submitted by the participants during follow-up
Secondary outcome [3] 414158 0
Durability of symptom relief at 12 months.
Timepoint [3] 414158 0
12 month post procedure through follow-up consultation. Data will be gathered from the British Society of Gynecologic Endoscopy (BSGE) pelvic pain questionnaire accomplished and submitted by the participants during follow-up
