2. DEFINITION & PATHOGENESIS
Placenta accreta occurs when there is a defect of the decidua basalis , in conjunction with an imperfect development of the Nitabuch membrane , resulting in abnormally invasive implantation of the placenta .
Nitabuch membrane is a fibrinoid layer that separates the decidua basalis from the placental villi.
3. HISTOLOGICAL CLASSIFICATION
4. INCIDENCE There is marked increase in the incidence of placenta accreta .
In 1950----- 1 in 30,000 deliveries .
In 1977-----1 in 7,000 deliveries .
In 1985-1994-----1 in 2500 deliveries .
In 1982-2002-----1 in533 deliveries .

5. placenta accreta has been reported to result in a 7% mortality rate .
The most common indication for birth related hysterectomy, accounting for 4060% of cases.

6. DIAGNOSIS Placenta previa -accreta
7. Color Doppler
Demonstrating turbulent flow through placental lacunae ,with abnormal vessels linking the placenta to the bladder.
8. Magnetic resonance imaging
The role of MRI is to complement, rather than replace, information obtained via standard sonographic imaging.
The main advantage offered by this type of imaging is :
The ability to diagnose posterior placenta accreta more confidently.
The assessment of bladder invasion in cases of placenta percreta.
9.
The mean gestational age at diagnosis of placenta accreta by ultrasound is 29 weeks (range:2833 weeks) .
The mean gestational age at delivery is 36 weeks
(range: 3238 weeks).

10. COMPLICATIONS
Massive obstetric hemorrhage is the most common complication .
Disseminated intravascular coagulopathy .
Adult respiratory distress syndrome .
Renal failure .
Infection
Death.
11. Abstract STUDY DESIGN :
Retrospective analysis of medical records & histopathological finding .
POPULATION :
Women delivered at Makassed Hospital 2007 / 2008 of whom 15 cases of invasive placenta identified.A finding confirmed by histopathology .
METHODS :
Retrospective analysis complemented with direct communication with patient ,using SPSS to analyze data .
CONCLISIONS : at the end of presentation .
12.
Incidence in 2007
.1:460 deliveries.
Incidence in 2008
.1:300 deliveries.
16.
All of our cases were diagnosed antenatally .
17. Identified risk factorshistory of :
C S .
E &C .
IUCD .
Other uterine instrumentation .
22. Gestational age
24. Preoperative management The woman should be informed of the diagnosis and potential complications .
Antenatal corticosteroid to be given .
Consent form of caesarean hysterectomy .
Delivery should be scheduled for optimal availability of necessary personnel and facilities.
A preoperative anaesthesia consultation should be obtained.
Adequate blood and clotting factors should be available at the time of delivery .
An intensive care unit should be available for postoperative care, as needed.
25.
Immediate preoperative bilateral uretric stents were inserted in a couple of cases .
26. Intraoperative management of planned cesarean hysterectomy :
A vertical skin incision provides good exposure .
A vertical uterine incision is made above the upper edge of placenta .
Delivery of the baby .
Placenta left "in situ, with minimal manipulation.
Extrafascial hysterectomy is then performed .
29. Blood transfusion
30. Continued
35. Neonatal outcome
37. CONCLUSIONS Incidence of invasive placenta at Makassed hospital is
one case in 370 deliveries .
Invasive placenta associated with significantly high morbidity & mortality world wide , proudly the outcome in our hospital was excellent , with NO MORTALITY & MINIMUM MORBIDITY .
Excellent neonatal outcome .
38. Continued
.
Finally , maternal & neonatal outcome can be optimized by the availability of :
Senior obstetrician with advanced surgical skills .
Senior anesthesiologist & intensive care facilities .
Advanced lab & blood banking facilities .
Urological back up .
Intensive care baby unit .
