A total of PubMed ISI publication full file the inclusion criteria found were 19 that published from 2000 until 2018. Number 1 (2016) is a prospective study... "Comparison between two ways of management protocols to control bleeding in cases of (PPH) during (C/S) for PP. Using Bakri Balloon versus No-balloon protocol." It is concluded that utilizing the balloon for the management of PPH after CS in cases of PP is a practical approach to reduce the complication and it should be affordable worldwide [7].

Number 2 (2016) is a retrospective study. It is concluded that 4.1 per 1000 is the prevalence of placenta previa, and it is still the vital cause of maternal morbidity and death. Every hospital must have a clear procedure and protocol designed for the management of placenta previa [8].

Number 3 (2016) is a retrospective chart review of all cases of repeat cesarean sections up to 6 CS looking at complication and outcome. It concluded that one of the complications related to multiple CS is placenta previa after the first and subsequent pregnancies [9].

on the relation of implantation of the placenta to internal Os; it is either complete placenta previa, partial or marginal [4]. Advanced maternal age, grand multiparity, abortion smoking and previous CS, or placenta previa are known risk factors to increase the risk of placenta previa [5]. Placenta accreta is a clinical condition when part or the entire placenta invades the uterine wall. Placenta increta is when the chorionic villi invade the myometrium and percreta when the invasion occurs through the myometrium and serosa, and occasionally into adjacent organs, such as the bladder [6]. The objective is to review all articles published from Saudi

In a retrospective study, all publications of placenta previa in our region are reviewed. The survey conducted at King Abdulaziz University in Jeddah, Saudi Arabia, to identify the possible complication of abnormal placentation such as placenta previa. PubMed, which is a free database search, used to determine the number of publications of placenta previa in Saudi Arabia data collected for 18 years from January 2000 to May 2018. Only Institute for Scientific Information (ISI) publication is selected "All abstracts that appeared in the PubMed database collected analyzed meticulously for the year of publication, type of research, institute and the region, and the complication that illustrated in each publication." The inclusion criteria, as well as exclusion criteria, were clearly defined before the study. The inclusion criteria were studies that were ISI, carried out in and or published from (the Kingdom of Saudi all Arabia), about placenta previa in Saudi Arabia. The exclusion criteria were as follows: all studies were not ISI or were neither conducted nor published from Kingdom of Saudi Arabia. The number of publication retrieved when we used (placenta previa Saudi Arabia) was 40, but only 19 study included as for inclusion criteria. The studies defined according to their abstract, the title, year of publications, the aim, material and methods, results and conclusions. Statistical analysis SPSS statistical software (version 22) is used for analysis. Data are coded for numbers

Number 4 (2015) is a comparative study to identify the outcome and risk factor in grand multiparity. There are no significant associations found in placenta previa, abruption, postpartum hemorrhage, preterm labor, and neonatal intensive care unit admission. No fetal or maternal mortality reported in this study. Grand multiparity remains a major obstetric problem and has many medical and obstetrical complications [10].

Number 5 (2015) is a prospective descriptive study to identify the maternal and fetal outcomes and the prevalence of cases of major placenta previa. The frequencies of bowel injury were only a couple cases give 3.8%, and bladder injuries were 13.2% (n = 7). No maternal death is reported. The rate of placenta previa is similar to the previous publication, but the rate of complicated placenta abnormality such as accreta is higher, which gives results in more intraoperative complication and neonatal mortality [11].

Number 6 (2014) is a study to evaluate the safety of labor if the placental edge between 11 and 20 mm from the internal cervical Os diagnosed by transvaginal sonography. It is concluded that it is justified to allow a trial of labor with low risk of subsequent obstetrical hemorrhage [12].

Number 7 (2013) is a retrospective cohort study to evaluate fetal growth and maternal outcomes in patients with placenta previa (PP) and placenta accreta (PA). The babies were relatively small (level 2 evidence) [13].

Number 8 (2013) is a retrospective case-control study of multiple repeats of cesarean sections: to determine the operative difficulties, maternal complications, and fetal outcome. Patients must be informed of detailed risks of multiple CS (PP) and encouraged to have tubal ligation [14].

Number 9 (2013) is a prospective observational study. To Evaluate the use of MRI and ultrasound prenatally to diagnose placenta accreta. Ultrasound can be successfully used in the diagnosis. MRI can give additional information in doubtful cases [15].

Number 10 (2012) is a prospective study to identify the risk of complication and maternal and perinatal outcome in subjects with placenta previa with or without the previous cesarean section. One of the risk of postpartum hemorrhage is blood transfusion which more in patients with pp and previous cs [16].

Number 11 (2009) is a retrospective study to compare risks and outcome between the different class of placenta previa (PP). Marginal placenta previa or low-lying placenta carried lower risk [17].

Number 12 (2009) is a retrospective study to look at the effect of utero-vaginal packing in controlling primary postpartum hemorrhage due to placenta previa/accreta. Packing is of advantage in achieving hemostasis, in cases of postpartum hemorrhage due to low-lying placenta previa/accreta and to conserve the uterus in women with low parity [18].

Number 13 (2006) is a retrospective study to compare the complication and outcome of multiple cesarean sections with those with one previous CS. Pelvic adhesions and bladder injury and placenta previa were higher in women with a history of multiple previous CS [19].

Number 14 (2004) is a retrospective study to identify multiple cesarean section morbidity. The maternal morbidity increased with multiple CS. The risk of significant maternal morbidity was significantly higher with more than 4 CS worse at the sixth CS for placenta previa [20].

Number 15 (2004) is a retrospective study of women with multiple CS from 3 or 4 to 5–9 to determine the maternal morbidity and mortality associated with multiple repeats cesarean sections.

Repeat cesarean sections 5–9 carry no particular additional risk for the mother or the baby when compared with the lower (3 or 4) repeat cesarean sections. Repeat cesarean sections carry no particular additional risk for the mother or the baby when compared with the lower (3 or 4) repeat cesarean sections [21].

Number 16 (2003) is a retrospective study of higher order multiple repeats cesarean sections: It is concluded that the incidence of hysterectomy, uterine pelvic dehiscence, placenta previa, and accreta and bladder injury was similar in the two groups. The rate of postpartum pyrexia, wound infection, urinary tract infection, and blood transfusion was also comparable in the two groups [22].

Number 17 (2003) is a retrospective study and a review of 17 cases of emergency peripartum hysterectomy. Uterine atony is still the leading cause of primary postpartum hemorrhage and the primary indications of peripartum hysterectomy [23].

Number 18 (2001) is a case series of using Tamponed-balloon for obstetrical bleeding, caused by low-lying placenta previa, and in one woman with cervical pregnancy. Hemostasis is achieved by using a large volume, fluid-filled tamponed balloon [24].

Number 19 (2000) is a prospective observational study with an objective to determine the use of transvaginal sonography in visualizing migration and predict the mode of delivery. All the cases had confirmed the diagnosis of placenta previa before 32 weeks' gestation, and migration up to a distance of more than 3 cm from the internal cervical Os occurred in 24 patients (38%) by 36 weeks' gestation [25].
