  • Introduction
  • Relatively uncommon
  • serious morbidity and even maternal death.
  • difficult to diagnose
  • symptoms non-specific and
  • bleeding is often concealed.
  • Haematoma
  • localized collection of blood outside of blood
    vessels
  • gt 2.5 cm

4
  • Incidence
  • 1300 to 11000 deliveries
  • (Thakar and Sultan 2009)
  • gt4 cm 1/1000 deliveries.
  • Supralevator lt infralevator
  • Surgical intervention
  • 1/1000 deliveries

5
  • Types
  • I. Infralevator
  • below the levator ani muscle
  • usually around vulva, perineum and lower vagina
  • 1. Vulval
  • limited to the vulval tissues superficial to the
    anterior urogenital diaphragm.
  • Haematoma evident on the vulva.
  • 2. Vulvovaginal
  • Evident on the vulva but
  • extend into the paravaginal tissues.

  • 3. Paravaginal
  • confined to the paravaginal tissues in the space
    bounded inferiorly by the pelvic diaphragm and
    superiorly by the cardinal ligament.
  • not obvious externally but can be diagnosed by
    vaginal examination.
  • often occludes the vaginal canal and extends into
    the ischiorectal fossa.

9
  • II. Supralevator Supravaginalsubperitoneal
  • Spread
  • upwards and outwards beneath the broad lig. or
  • downwards to bulge into the wall of the upper
    vagina, or
  • backwards into the retroperitoneal space.

  • Aetiology
  • Injury
  • Direct episiotomy, forceps or
  • Indirect radial stretching of the birth canal as
    the fetus passes through.
  • 80 failure to achieve haemostasis
  • e.g. at the apex of an episiotomy or tear.
  • 20 concealed ruptured vessel with an
    apparently intact perineum
  • (Thakar and Sultan 2009)
  • 50 spontaneous delivery.
  • Coagulopathies von Willebrand disease, are rarer
    causes.

13
I. Infralevator Usually associated with vaginal
birth 1.Vuval or vulvovagial injury to the
branches of the pudendal artery posterior
rectal transverse perineal posterior labial
arteries 2. Paravaginal Injury to descending
branch of the uterine artery.

  • II. Supralevator
  • Injury to uterine artery branches in the broad
    ligament.
  • May occur after spontaneous birth
  • More commonly
  • operative vaginal birth
  • difficult CS
  • Due to an extension of a tear of the cervix,
    vaginal fornix or uterus

17
  • Presentation and differential diagnosis
  • Onset
  • usually within a few hours of delivery.
  • Speed of diagnosis depend on
  • extent of the bleeding
  • associated consequences
  • level of awareness of medical staff.

18
  • Classical symptoms
  • Pain
  • Excessive perineal pain is a hallmark symptom
  • its presence should prompt pelvic examination.
  • Over a few days in a small haematoma in an
  • Episiotomy
  • Restlessness
  • Rectal tenesmus (constant need to empty bowels)
    within a few hours after birth

19
  • Collapse
  • within a few hours of delivery in large
    haematoma
  • Bleeding
  • Continued vaginal
  • if a haematoma ruptures into the vagina
  • DD from other causes of PPH e.g. atonic uterus.
  • Rare symptoms
  • Retention of urine
  • unexplained pyrexia.

20
  • Vulval and vulvovaginal haematomas
  • Typical symptoms
  • pain and swelling in the perineum.
  • DD
  • abscesses.
  • pain of an episiotomy
  • tear or
  • haemorrhoids Examination

21
  • Paravaginal haematomas
  • Typical symptoms
  • Rectal pain
  • lower abdominal pain (often vague)
  • symptoms of hypovolaemia often out of proportion
    to revealed blood loss.
  • These non-specific symptoms can readily be
    attributed to other causes delay the correct
    diagnosis.

22
  • Supravaginal haematoma
  • Symptoms
  • Abdominal pain
  • no vaginal symptoms.
  • Signs
  • hypovolaemia collapse.
  • shock elevated pulse, decreased BP, pale,
    sweaty, clammy, dizzy
  • Abdominal examination
  • uterus is deviated upward and laterally, to the
    opposite side from the broad ligament haematoma.
  • DD
  • pelvic mass abscess
  • intra-abdominal bleeding.

23
  • Investigations
  • Blood tests
  • CBC
  • Coagulation screen
  • mandatory determine baseline values
  • should be repeated as necessary.
  • Cross matching
  • according to the clinical picture.
  • Transfusion
  • more likely to be necessary with paravaginal and
    subperitoneal than with vulval haematomas.
  • .

24
  • Imaging
  • US, CT and MRI
  • diagnosing haematomas above pelvic diaphragm
  • assess any extension into the pelvis
  • MRI
  • location, size and extent of a haematoma
  • monitoring progress or resolution.
  • DD between other causes of a pelvic mass
    abscess or endometrioma.

25
Management Aims prevent further blood
loss, minimise tissue damage, relieve pain
reduce the risk of infection. Prompt resolution
reduced Scarring postpartum pain dyspareunia.
26
  • Assessment high index of suspicion is required.
  • Prompt examination of vulva, perineum, vagina
  • Identify site of haematoma
  • Whether it is still expanding
  • Estimate blood loss
  • Monitor ongoing blood loss often underestimated

27
  • 1. Resuscitative measures
  • first line of treatment.
  • Fluid replacement
  • crystalloids/colloids Hartmanns, sodium
    chloride 0.9 , Gelafusine
  • Assessment of coagulation status essential if
    heavy bleeding or signs of hypovolaemia.
  • Blood should be available for transfusion.
  • Urinary catheter
  • monitor fluid balance
  • avoid possible urinary retention resulting from
    pain, oedema or the pressure of a vaginal pack.

28
  • 2. Conservative management
  • Indication
  • Small (5 cm), static haematomas
  • Not for
  • Larger haematomas
  • longer stays in hospital
  • An increased need for antibiotics and blood
  • transfusion and greater subsequent operative
  • intervention.
  • Haematoma that expands acutely is unlikely to
    settle with conservative measures.

29
  • Steps
  • Broad spectrum antibiotics
  • Ice packs
  • Analgesia
  • 1. Regular paracetamol
  • 2. NSAID diclofenac Voltaren 50 mg tds),
    contraindications pp hge, PET, renal disease,
    concurrent use of other NSAIDs, aspirin, digoxin
  • 3. intramuscular opioid
  • 4. Avoid rectal administration of analgesics
  • Regular review
  • ensure that bleeding has settled and haematoma
    has resolved.

30
  • 3. Surgical
  • Indication
  • Large (5 cm) vulval haematomas
  • Steps
  • Adequate anaesthesia
  • Evacuation
  • Incisions should be placed to minimise scarring
    (this is often medially).
  • Clot should be evacuated
  • Any apparent bleeding points ligated.

31
  • Primary closure
  • The exact origin of the bleeding is rarely
    identified
  • The space should be closed with deep mattress
    sutures and the overlying skin reapproximated
    without tension.
  • Care must be taken to avoid damage to contiguous
    structures (such as the ureters, bowel and
    bladder) during repair procedures.
  • Compression
  • The vagina should be packed tightly for 1224 h.

32
  • Drains
  • usually brought through a separate site distant
    from the repair.
  • useful to highlight ongoing or recurrent
    bleeding.
  • defeat the object of packing, which is to
    tamponade bleeding vessels.
  • What is optimal management ?
  • primary repair (with or without drains)
  • primary repair with packing, and
  • packing alone have all been advocated.

33
  • Subperitoneal haematomas
  • 1. Small, stable
  • conservative.
  • 2. Larger
  • Surgical abdominal approach
  • identification and ligation of bleeding vessels.
  • Arterial embolisation
  • under radiological control is now an alternative
  • Broad spectrum antibiotic
  • Regular review
  • ensure that bleeding has settled and
  • haematoma has resolved.

34
  • Persistent bleeding
  • Haematomas can recur after surgical management.
  • Continued monitoring for signs of blood loss
  • essential.
  • If first line management fails
  • further surgical intervention
  • The haematoma cavity should be explored again.
  • Ligation of the internal iliac artery, or even
  • hysterectomy, may be necessary. or
  • occlusion of the internal iliac artery/ies by
    balloon catheter or embolisation

35
4. Pelvic arteriography and arterial
embolisation Success rate over
90. Steps Pelvic circulation is accessed via
the femoral a Angiography is used to identify
bleeding vessels before selective embolisation.
Embolic agents temporary absorbable,
gelatin-impregnated sponges permanent metal
coils. Performed under light sedation take 12 h
36
Complications Uncommon 9 low grade fever pelvic
infection ischaemic buttock pain temporary foot
drop groin haematoma Vessel perforation. Use of
temporary embolic agents reduces the risk of
ischaemic problems.
37
Advantages preserve fertility (despite exposure
of the ovaries to ionising radiation) most women
continue to menstruate. avoid the risks of
laparotomy, although the option of surgery is
retained. limitation experience equipment. Indic
ation first line treatment for persistent
bleeding

    left internal iliac artery runs showing contrast
    extravasation (arrows) from the inferior vesicle
    branch (arrowheads) indicating an active bleed.
  2. An oblique view showing more extravascular
    contrast accumulation in the delayed phase
    (arrows).

Post embolisation image showed blockage of the
inferior vesicle artery and the bleeding was
successfully arrested.
40
  • Prevention
  • Good surgical technique, with attention to
    haemostasis in the repair of lacerations and
    episiotomies
  • However, haematomas are not unavoidable.

41
  • Conclusion
  • Genital tract haematomas are uncommon and can
    cause diagnostic confusion.
  • Clinicians must be alert to haematomas as a dd of
    postpartum pain and bleeding.

42
  • Key elements of management of puerperal genital
    haematoma
  • The most important factor in correct diagnosis is
    clinical awareness
  • Excessive perineal pain is a hallmark symptom
    its presence should prompt examination
  • Aggressive fluid resuscitation/blood transfusion
    may be required

43
  • Coagulation status should be monitored
  • Treatment should be carried out in an operating
    theatre
  • A urinary catheter should be used to prevent
    urinary retention and monitor fluid balance
  • The threshold for using antibiotics should be low
  • There is no evidence to support best management,
    which can be primary repair or packing, with or
    without insertion of a drain
  • Awareness should be maintained after primary
    repair/packing, as recurrence is common
