Whenever a woman of child bearing age presents with menorrhagia (excessive bleeding during menstruation), dysmenorrhea (painful menses), or recurrent abortion.
Uterine fibroid is a common benign tumour smooth muscle cells and fibrous connective tissue that develop within the walls of the uterus. It generally affects the middle-aged women and present with menorrhagia and pressure effects on the urinary bladder and or the rectum. Women with fibroids may also have dysmenorrhea. When occurring in the child bearing age, these fibroids may interfere with pregnancy and the lady is either unable to conceive or unable to carry the pregnancy till completion. Uterine fibroid embolisation (UFE) is a minimally invasive, percutaneous, endovascular (interventional radiological) therapy to treat the fibroids, by blocking the arteries supplying the fibroid.
Ministry of Health and Family Welfare, Government of India has issued the Standard Treatment Guidelines for Uterine Fibroid Embolisation.
Following are the major recommendations :
It is indicated for treatment of symptomatic uterine fibroids, causing menorrhagia /dysmenorrhea / pressure effects on rectum or urinary bladder.
INCIDENCE OF THE CONDITION IN OUR COUNTRY
Fibroids is a common ailment of the middle aged women, occurring in up to 20%.
Other causes of uterine masses could be cancer cervix, endometrial cancer. Occasionally ovarian cancer may mimic a uterine fibroid. Imaging with Ultrasound / MRI and histopathological studies can give the correct diagnosis.
PREVENTION AND COUNSELING
Menorrhagia / lower abdominal masses should be evaluated by imaging and histopathology, to arrive at the correct diagnosis, and early appropriate treatment should be implemented. The middle aged women should be always evaluated with a PAP smear to rule out any malignancy of uterine cervix.
OPTIMAL DIAGNOSTIC CRITERIA, INVESTIGATIONS, TREATMENT & REFERRAL CRITERIA / FOLLOW UP
- Ultrasound: Reveals a spherical mass with heterogeneous middle level echoes. Most fibroids are intramural. Occasionally they may be pedunculated and apparently detached from the uterus or they could be subendometrial There is always an accompanied displacement of the endometrial echo, which also serves an indirect indicator for the isoehoic fibroids.
- MRI: Reveals a uterine mass that is heterogeneously hyperintense on T2 and isointense on T1 images. There is hypertrophy of the uterine arteries.
- Ultrasound Pelvis
- MRI Pelvis
- PAP smear from Cervix
- Endometrial biopsy, if there is suspicion of endometrial Ca
- Blood – Hb, TLC, DLC, ESR
- Blood – Platelets count
- Blood – PT(INR) and APTT
- Blood Creatinine
Uterine fibroid embolisation – The uterine artery is accessed endovascularly and the tip of the catheter / microcatheter is placed distal to the ovarian / cystic / cervical branch, and embolised with Poly Vinyl alcohol particles, till the flow becomes very sluggish.
Patients meeting the criteria for UFE should be referred to centers equipped with capability to perform UFE.
Patient would be admitted a day prior to the embolisation and managed as inpatient till 2-3 days till the pain and nausea gets tolerable. There after Clinical follow up is done at 2 week, 6 weeks, 3 months and 6 months. During these follow up ultrasound could be done to assess the size of the fibroid.
Situation 1: At Secondary Hospital/ Non-Metro situation: Optimal Standards of Treatment in Situations where technology and resources are limited
Clinical Diagnosis: As above
Investigations: As above
Standard Operating procedure
Patient would be assessed and evaluated by the primary gynecologist to rule out any other gynecological problems. Thereafter patient will be assessed by the interventional radiologist for the feasibility of embolisation. Most of the times the procedure would be done under local anesthesia and if required the anesthesiologist’s consultation can be taken. The patient’s uterine artery would then be accessed by endovascular approach; the catheter tip will be placed beyond the branches to the ovary, urinary bladder and uterine cervix. Then polyvinyl alcohol particle would be injected for embolisation of the artery till the flow becomes sluggish.
a. In Patient: UFE is to be done as inpatient.
b. Out Patient: no.
c. Day Care: no
e) Referral criteria: As above
Situation 2: At Super Specialty Facility in Metro location where higher-end technology is available
Clinical Diagnosis: As above
Investigations: As above
Treatment: As above
Standard Operating procedure: As above.
a. In Patient-The procedure will be done as an inpatient therapy
b. Out Patient – No
c. Day Care – No
Referral criteria: As above.
