Review
A placenta previa, whether found fortuitously by ultrasound or with the clinical emergency of maternal hemorrhage, carries significant maternal and fetal risk. Accurate diagnosis, judicious expectant management with transfusion as required, and delivery at the time of fetal lung maturation can lead to the most favorable outcome. Anticipation of the clinical complication of placenta accreta may avoid some serious consequences. Clinical judgement and skill in the performance of cesarean sections, dilatation and curettage, and other forms of uterine invasive techniques may help to keep subsequent incidence of placenta previa at a reasonably low rate.

Review
OBJECTIVE
Produce recommendations for the management of placenta previa and placenta accrete.
METHODS
A literature search was conducted using Medline and the Cochrane Library over a period from 1950 to 31/12/2013. Recommendations of the latest scientific societies have also been consulted.
RESULTS
In cases of placenta previa, if bleeding episode before 34weeks gestation occurs, a short hospitalization and tocolysis may help stop bleeding (grade C). Vaginal delivery is preferable when the distance between the internal cervical os and the placental edge is greater than 20mm. When this distance is less than 20mm, vaginal delivery is possible (professional consensus). Caesarean section is recommended in cases of placenta overlapping the internal os (professional consensus). Antenatal screening placenta accreta could improve care (EL3). Upon discovery of a placenta accreta during childbirth, it is better to avoid a forced removal of the placenta (grade C). Conservative treatment or cesarean hysterectomy are possible (grade C). The management of placental abnormalities should be planned and managed with a multidisciplinary team (professional consensus). The use of blood-saving techniques such as "cell saver" is possible in situations where early intraoperative bleeding would be>1500mL (grade C). There are no studies that have sufficient methodological value to recommend an anesthetic technique [general anaesthesia (GA) or neuraxial anaesthesia] over another in the context of placental abnormalities (grade B). When a major bleeding risk is identified, GA can be chosen in order to avoid emergency conversions in difficult conditions (professional consensus).
CONCLUSION
Placental insertion abnormalities require anesthetic and obstetric coordination. Delivery must be planned in a suitable structure.

Review
The author present contemporary methods for diagnosis of placenta praevia. He compare old methods as X-ray placentography, radioisotope placentography with using ultrasound to determine the location of placenta. Placenta praevia can be diagnosed prenatally using ultrasound through transabdominal, afterwards with transvaginal ultrasound. This decrease prolonged hospitalization and needless Cesarian section. The author made parallel between frequency in beginning of pregnancy with frequency at term. With advance of gestational age the frequency of placenta praevia decrease. This decreasing incidence with increasing gestational age is attributable to the concept of placental migration. When the placental edge was inicially > 2 cm from cervical os, migration occurred in all cases and no Cesarean sections were necessary for placenta praevia. When the placenta overlapped the cervical os by > 20 mm at 26 weeks, all the women required Cesarian delivery. The author present basic strategies to reduce maternal and fetal mortality and morbidity from placenta praevia. All pregnant women should have a routine sonogram at 20 weeks gestation. When the area over the internal os cannot be identified, a transvaginal sonogram should be performed. Women who have a lower placental edge which is < 1 cm from internal os should have a sonogram at about 34-35 weeks gestation. When placenta praevia is present should be perform prior Cesarian delivery.
