BACKGROUND
Placenta praevia is the most common cause of antepartum haemorrhage. It is a potentially life threatening condition associated with morbidity and mortality. There is no study on the pattern and management of placenta praevia in Sagamu.
AIM AND OBJECTIVES
To determine the risk factors, pattern of presentation and management outcome of pregnancies complicated by placenta praevia.
DESIGN
This was a five-year retrospective study Setting: Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State, Nigeria.
MATERIALS AND METHODS
Relevant information was retrieved from the case notes of all patients who presented with placenta praevia from 1st January, 2013 to 31st December, 2017. The data were analyzed by using SPSS version 21.
RESULTS
Out of the 5124 deliveries, there were 47 cases of placenta praevia giving a prevalence of 0.92%. Twenty-one subjects (50%) were within 31-40 years age group. The modal parity was 1. Twenty women (47.6%) had parity of 1-2. Thirty subjects (71.4%) were unbooked. Painless vaginal bleeding was the commonest mode of presentation in 30(73.8%) women while Type III was the commonest grade 15(35.7%). Nineteen subjects (45.2%) had no identifiable risk factors. Postpartum haemorrage was the most common complication (23.8%). There was no maternal death while the perinatal mortality was 13.5%. There was no significant association between booking status, type of placenta praevia, mode of delivery, blood loss at delivery, and the one minute APGAR score.
CONCLUSION
The prevalence of placenta praevia in Olabisi Onabanjo University Teaching Hospital is comparable with other tertiary facilities in Nigeria. Upgrading comprehensive emergency obstetric services, improving neonatal services and a multidisciplinary approach to management of all cases will ensure good outcome for the mother and baby.

Comparative Study
One hundred and seventy-three cases of placenta previa managed at the Women's Hospital of Los Angeles County-University of Southern California Medical Center from July, 1975, through June, 1978, were reviewed and compared to a similar series of cases studied in the same institution in 1969. The perinatal mortality of 12.6% was roughly one half of that in the earlier study. The fetal death rate did not change significantly, but the neonatal mortality was markedly less, especially in the 27-to-32-week range. Expectant management was employed in 65.8% of patients, as compared to 42.6% in 1969. The higher rate of expectant management was characterized by the aggressive use of antepartum transfusions in the face of moderate-to-severe bleeding in lieu of delivery, as well as the occasional use of tocolytic agents for inhibition of premature labor in the presence of vaginal bleeding. Elective termination of pregnancy utilizing the lecithin/sphingomyelin (L/S) ratio for determination of pulmonary maturation also resulted in significantly less overall neonatal morbidity and mortality. These multiple factors appear to have contributed to a dramatic reduction in the perinatal mortality associated with placenta previa.

A prospective study was undertaken to determine the relationship between previous caesarean section (CS), placenta praevia and placenta praevia accreta. Of 41,206 consecutive deliveries 1851 had had previous caesarean section and 222 had placenta praevia. Of the cases of placenta praevia, 175 occurred in the uterus and 47 occurred after previous CS. Placenta praevia complicated 2.54% of cases with a previous caesarean section compared with 0.44% of cases with no scar--a 5-fold increase. In patients with placenta praevia occurring with a previous scar, 18 were complicated by placenta accreta (38.2%) compared with only 8 (4.5%) in unscarred uteri. After one caesarean section, placenta praevia was complicated by accreta in 10% of cases and after two or more this was 59.2%. The risk of hysterectomy with placenta praevia and uterine scar was 10% but with placenta praevia accreta it was 66%. There was one maternal death in the placenta praevia accreta group.

Clinical Trial
OBJECTIVE
The aim of this study is to present our experience with surgical management of placenta praevia percreta.
METHODS
This study was conducted from January 2009 through March 2014 at Harran University Hospital and was a chart review of all patients who underwent caesarean hysterectomy with the placenta left in situ for placenta praevia percreta.
RESULTS
The study group comprised 58 patients. All of the patients underwent ultrasound mapping of the placental area before surgery. Emergent caesarean hysterectomy was only performed in 9 patients; 49 patients underwent planned caesarean hysterectomy. Bilateral internal iliac artery ligation was performed in all cases. Four patients (6.9 %) had bladder damage, one patient (1.7 %) required cystotomy, and one patient (1.7 %) required re-operation because of postoperative hemorrhage. The mean operative time was 141.6 (range: 95-355) minutes. Only 17 (29.3 %) patients were administered more than four units of red blood cells. There was no ureteral damage or maternal death. Furthermore, there were no complications in 42 (72.4 %) patients.
CONCLUSIONS
Caesarean hysterectomy for placenta praevia percreta is associated with increased maternal morbidity. However, preoperative diagnosis of placenta praevia percreta, ultrasound mapping of the placenta, and the presence of a multidisciplinary experienced team may decrease maternal morbidity and mortality. Moreover, the urinary system may be protected in the patients with placenta praevia percreta without serious morbidity.

BACKGROUND
Placenta previa percreta with invasion of the broad ligament and uterine cervix is an extremely rare condition and carries high maternal and fetal morbidity and mortality.
CASE
A 39-year-old, multiparous woman with two previous cesarean sections presented in active labor at term with placenta previa percreta involving the left broad ligament and cervix. The patient was managed by antepartum diagnosis of placenta previa accreta, supracervical hysterectomy, and blood transfusion.
CONCLUSION
This case was managed consistent with the literature, and favorable maternal and fetal outcomes were achieved.

UNLABELLED
Pregnancies complicated by the placenta praevia are associated with an increased risk of massive obstetric bleeding and high rates of hysterectomy which are often caused by the placenta accreta. was to identify the risk factors for placenta praevia associated with PAS disorders and the efficacy of distal haemostasis during Cesarean delivery.
METHODS
This was a cohort study carried out between 2014 and 2020 in 532 women with abnormal placental localization and attachment. The placental attachment spectrum (PAS) disorder diagnosis was confirmed during the surgery and by the histology results in 164/532 participants. Depending on the surgical approach during the Cesarean delivery, patients were divided into three groups. In Group 1 ( = 52), patients underwent bilateral uterine artery ligation. In Group 2 ( = 33), we used the combined compression haemostasis approach including the placement of tourniquets and insertion of an intrauterine balloon for controlled tamponade. In Group 3 ( = 79), we used the combination of surgical haemostasis with the controlled intrauterine tamponade using the vaginal and intrauterine Zhukovsky balloon.
RESULTS
PAS was observed in 30.8% of the placenta praevia cases, and in 93.3% was associated with the presence of a uterine scar. Women with the placenta praevia and PAS had a significantly higher number of past deliveries ( = .001). According to the FIGO classification, 53.8% of women with placenta praevia observed during the Cesarean had РА1 and 46.2% PA2. With regards to the PAS disorders observed in 30.8% of patients, 38.4% had PAS3, 34.7% PAS4, 18.3% PAS5 and 8.5% PAS6. The histology analysis showed normal placental attachment in 42.9% of the total number of study participants, placenta accreta in 28.2%, placenta increta in 16.7%, and placenta percreta in 12.2%. In Group 1, we performed the resection of uterine wall with the attached portion of the placenta in 13.5% of women, in Group 2 in 30.3% women, and in Group 3 in 50.6% women. There was a significant 4.8-fold reduction in the number of hysterectomies in Group 3 versus Group 2 ( = .043) and a 4.4-fold reduction in Group 2 versus Group 1 ( = .003). In Group 2, the volume of blood loss was 1.3-fold lower and in Group 3 1.5-fold lower than in Group 1. : The techniques of compression distal haemostasis evaluated in this study in women with PAS are efficacious in the reduction of adverse maternal outcomes and should be used more widely in clinical practice.
