Uterine Fibroids Flashcards
Define fibroids
Benign neoplasms that arise from the uterine smooth muscles.
Risk factors
Nulliparity/ low parity
black race
genetic/ family history
Reproductive age
why is uterine fibroids associated with reproductive age
this is because it is hormone dependent.
Peak age for fibroid
35 - 45 years
Types of fibroid
- Intramural- within the myometrium
- Subserous- projecting from the serosa
- Intraligamentary- between the layers of broad ligament
- Submucous- projecting into the uterine cavity
- Pedunculated–subserous fibroids may grow a pedicle and become pedunculated. T
Presentation of fibroids
- Symptomless- may be apparent only at clinical examination for other reason eg. during infertility
investigation, pregnancy or ultrasonography for other reasons
Abdominal swelling
Pressure effects- urinary frequency, urinary retention, edema, varicose veins
Abnormal uterine bleeding- menorrhagia, intermenstrual bleeding
Pain due to torsion, degeneration (red), infected fibroid
Dysmenorrhea–fibroid polyp being expelled through the cervix - infertility
- recurrent miscarriage
Complications of fibroid
Infection
Torsion
Degenerative changes
which type of fibroid is infection common in?
Submucous or fibroid polyps
Types of degenerative changes
Hyaline Cystic Red degeneration Calcific Sarcomatous(malignant)

Differential diagnosis for uterine fibroids
Adenomyosis
Ovarian tumor
Uterine cancer
Treatment
1. Conservative/observation for Small tumours Symptomless fibroid close to menopause 2. Surgery (myomectomy or hysterectomy) is indicated in Large fibroids Symptomatic fibroids eg menorrhagia, pain, urinary retention 3. others Uterine Artery Embolisation High energy focused ultrasound
Drugs used in medical manangement
GnRH analogues
Progesterone
COC
Mechanism of action of GnRH analogues
Induces pseudo menopause by down regulating GnRH receptors in the pituitary
Reduces size of fibroids, reduces vascularity thus reducing menstrual and operative bleeding
