Faculty of Medicine, Misurata University, LIBYA
2. Abnormal uterine bleeding (AUB)
Any deviation from normal frequency, duration
or amount of menstruation in women of
Reproductive age.
NORMAL MENSES
•Frequency: 21-35 d
•Duration: 3-7 d
•Volume: 30-80 ml
3. AUB- Clinical types
•Polymenorrhoea: frequent (<21 d) menstruation, at
regular intervals
•Menorrhagia: Excessive (>80 ml) & / or prolonged
menstruation, at regular intervals
•Metrorrhagia: Mensturation at irregular intervals.
10. •Definition:
Abnormal uterine bleeding in absence of
obvious pelvic organ disease or a systemic
disorder
•Incidence:
• 60 % of AUB
Dysfunctional uterine bleeding (DUB)
11.
12.
13. Mechanism of hemostasis during menstruation
2. Hemostatic plug formation
in the functional endometrium
1. Vasoconstriction in the
basal layer
Vascular occlusion is not complete, for short time
Until endometrial regeneration is completed
15. • Estrogen withdrawal bleeding
– Frequently occurs in peri-menopause.
– Short proliferative phase because of abnormal
follicular developments.
– E levels will vary with the quality and state of follicular
recruitment and growth.
– Bleeding might be light or heavy depending on the
individual response.
DUB- Pathophysiology
16. • Estrogen breakthrough bleeding
– Anovularoty cycles have no CL formation
– Progesterone is not produced
– The endometrial continues to proliferate under the
influence of unopposed E.
– Out-of-phase endometrium is shed in an irregular
manner that might be prolonged and heavy.
– Occur in absence of E decline.
DUB- Pathophysiology
17. Endocrine abnormality
Insufficient C. luteum leading
to short luteal phase
Persistent C luteum leading
to long luteal phase
Endometrial changes
Irregular or deficient
Secretory changes
Irregular shedding
A. Hormonal disturbances
DUB- Pathophysiology
18. B. Local endometrial defect
– Increase PGE2/PGF2α- VD
– Decreased Thromboxane A2/Prostacyclin ratio
– Increased activity of the fibrinolytic system locally in
the uterus
Why these changes occur and their exact
causal relation with menorrhagia have not
yet been determined.
19. AUB- Complications
• Iron deficiency anemia
• Endometrial adenocarcinoma: 1-2% of women with
anovulatory bleeding might develop Ca.
• Infertility: as with chronic anovulation, with or without
androgen production : PCOS, obesity, chr HTN, DM
are at risk.
• Complications of the etiology if present .
20. Aim:
1. Nature & severity of bleeding
2. Exclusion of organic causes
3. Ovulatory or anovulatory
Diagnosis
21. I. History
1. Personal: Age
2. Present H: onset of the problem, amount of
bleeding, duration, frequency, relation to
sexual intercourse, associated symptoms (pain,
abdominal mass).
3. Menstrual H.
4. Sexual activity: infection.
Diagnosis
22. 5. Obstetric and gynecological H
6. Contraceptive H.
7. Past medical & surgical H.
8. Family history
9. Current medication
Diagnosis
I. History
23. II. Examination:
1. General examination
Obesity (BMI)
Signs of androgen excess (hirsutism, acne)
Signs of hypo or hyperthyroidism
Galactorrhea
Visual field defect (pituitary lesion)
Ecchymosis, purpura
Signs of anemia
Diagnosis
24. 2. Abdominal examination
– liver, spleen, pelvi-abdominal mass
3. Local examination
• External genital lesions
• Speculum ex: assess the bleeding, vaginal discharge,
vaginal & cervix lesions
• Bimanual ex: uterine size, shape, countour, adnexa
for ovarian mass.
Diagnosis
26. III.Investigations
Local
1. Pap smear, cervical swap for infection
2. USS, saline-infusion-sonography
3. Endometrial biopsy, D & C biopsy
4. Fractional curettage
5. Hysteroscopy
Diagnosis
27. 1. TAS: can exclude pelvic masses, pregnancy
complications.
2. TVS:
• More informative than TAS.
• Measurement of the endometrial thickness.
• Endometrial carcinoma in postmenopausal is suspected if
endometrial thickness > 3.5 mm.
Ultrasonography
28. 3. Saline infusion sonography:
Infusion of saline into the uterine cavity.
Ultrasonography
29. TVS is recommended
1. Weight >90 Kg
2. Age > 40
3. Other risk factors for endometrial hyperplasia or
carcinoma e.g. infertility, nulliparity, family history of
colon or endometrial cancer, exposure to unopposed
estrogen.
Ultrasonography
30. Indications:
• Between 20 & 40 yrs.
• If endometrial thickness on TVS is >10mm,
endometrial sample should be taken to exclude
endometrial hyperplasia.
Aim
• Diagnosis of the type of the bleeding
• Exclude local pathology
Endometrial biopsy
31. Methods:
•As an outpatient procedure.
1.Pipelle curette
2.Sharman curette
3.Accrette
4.vabra aspirator
Advantages: An adequate & acceptable screening
procedure in females under 40 yrs
Endometrial biopsy
32. Indications
1. Mandatory after 4o yrs.
2. Persistent or recurrent bleeding after medical tt in
patient between 20 & 40 yrs.
Aim
1. Diagnosis of organic disease e.g. endometritis,
polyp, carcinoma, TB.
2. Diagnosis of the type of the endometrium,
hyperplastic, proliferative, secretory, atrophic.
Dilatation & Curettage (D & C)
33. 3. Arrest of the bleeding, if the bleeding is severe or
persistent, particularly hyperplastic endometrium.
Curettage is essentially a diagnostic & not a
therapeutic procedure.
Disadvantages
1.Small lesions can be missed.
2.The sensitivity of detecting intrauterine pathology is
only 65% .
Dilatation & Curettage (D & C)
35. • It is an endoscopic
visualization of endometrial
cavity.
Hysteroscopy
•Using a telescope, camera and light source.
• Use distensile media
CO2, normal saline, Glycin 1.5%
36. Hysteroscopy
1) To locate submucous myoma.
2) To diagnose uterine septum.
3) To locate & remove lost I.U.C.D.
4) To locate Endometrial polyp.
5) To locate uterine synechae.
6) To detect endometrial cancer.
• Indications
43. AUB- Treatment
• Principle of management
– Control of the bleeding followed by regulation
of menses.
– Induction of ovulation in patients with
infertility.
45. 1. General measures

Medical therapy
48. 1. Antifibrinolytics
Tranexamic acid (tranex)
Mechanism of action:
The endometrium possess an active fibrinolytic system,
& the fibrinolytic activity is higher in menorrhagia.

dysmenorrhea, headache, nausea, diarrhea &
depression persists for several months.
51. Side effects
• GIT upset, dizziness.
• Rarely: hemolytic anemia, thrombocytopenia.
•The degree of reduction of MBL is not as great as
it is with tranxamic acid but PSI have a lower side
effect profile.
