Abstract
OBJECTIVES To evaluate the occurrence of retained products of conception (RPOC) after termination of pregnancy in the first trimester and to assess the vascular signals with transvaginal ultrasonography (TVUS) examination in the detection of retained products. METHODS A retrospective cohort study was performed using TVUS examination in patients following termination of pregnancy. In cases of RPOC, 3 scales of vascular signal were identified: type 1, no or small amount, spot flow signals; type 2, medium amount, strip-like flow signals; type 3, rich amount, circumferential-like flow signals. The correlation between vascular signals and placenta accreta spectrum (PAS) staging was proposed by sonography and histopathology findings. RESULTS The 3 vascular patterns were differently distributed within non-RPOC as well as RPOC patients with and without PAS: type 1 vascular signal detection rates of non-RPOC and RPOC were 97.8% (262/268) and 28.1% (18/64), respectively. Of 64 cases of RPOC, 48.4% (31/64) of the patients had type 2 vascular signals. Vascular signals were enhanced in RPOC with PAS patients whose diagnosis was confirmed by histopathology. CONCLUSIONS The vascularity (amount of flow), vascular pattern (spot, strip- or circumferential-like flow), and the flow penetrating myometrium were significant findings for distinguishing concomitant RPOC with and without PAS. Additionally, RPOC may contribute to PAS progression, or PAS and RPOC in coordination strengthen the observed vascular signals.

Abstract
YKL-40 is a secreted glycoprotein that can promote invasion, angiogenesis and inhibit apoptosis, and was highly expressed in a variety of tumours. In this paper, we investigated the impacts of YKL-40 on proliferation and invasion in HTR-8/SVneo cells during placenta accreta spectrum disorders (PAS) development. The levels of YKL-40 protein in late-pregnant placental tissue were detected using immunohistochemistry and Western blotting, and gene expression using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The proliferation, migration, invasion and apoptosis abilities of HTR-8/SVneo cells were detected by cell counting kit-8 (CCK-8), Transwell, scratch assay, and flow cytometry, respectively. Our current results showed that YKL-40 was significantly increased in the PAS group compared to the normal control group (P < 0.01). Biological function experiments showed that YKL-40 significantly promoted the proliferation, migration and invasion of HTR-8/SVneo cells, and inhibited cell apoptosis. Knockdown of YKL-40 inhibited the activation of Akt/MMP9 signalling in trophoblast cells. These data suggested that YKL-40 might be involved in the progression of PAS, which may be attributed to the regulation of Akt/MMP9 signalling pathway.

Abstract
OBJECTIVE To report on the occurrence of urological complications in women undergoing Cesarean section for placenta accreta spectrum disorders (PAS). METHODS MEDLINE, EMBASE and the Cochrane databases were searched electronically up to 1 November 2022. Studies reporting on the urological outcome of women undergoing Cesarean section for PAS were included. Two independent reviewers performed data extraction using a predefined protocol and assessed the risk of bias using the Newcastle-Ottawa scale for observational studies, with disagreements resolved by consensus.The primary outcome was the overall occurrence of urological complications. Secondary outcomes were the occurrence of any cystotomy, intentional cystotomy, unintentional cystotomy, ureteral damage, ureteral fistula and vesicovaginal fistula. All outcomes were explored in the overall population of women undergoing surgery for PAS. In addition, we performed subgroup analyses according to the type of surgery (Cesarean hysterectomy, or conservative surgery or management), severity of PAS at histopathology (placenta accreta/increta and placenta percreta), type of intervention (planned vs emergency) and number of cases per year. Random-effects meta-analyses of proportions were used to analyze the data. RESULTS There were 62 studies included in the systematic review and 56 were included in the meta-analysis. Urological complications occurred in 15.2% (95% CI, 12.9-17.7%) of cases. Cystotomy complicated 13.5% (95% CI, 9.7-17.9%) of surgical operations. Intentional cystotomy was required in 7.7% (95% CI, 6.5-9.1%) of cases, while unintentional cystotomy occurred in 7.2% (95% CI, 6.0-8.5%) of cases. Urological complications occurred in 19.4% (95% CI, 16.3-22.7%) of cases undergoing hysterectomy and 12.2% (95% CI, 7.5-17.8%) of those undergoing conservative treatment. In the subgroup analyses, urological complications occurred in 9.4% (95% CI, 5.4-14.4%) of women with placenta accreta/increta and 38.5% (95% CI, 21.6-57.0%) of those described as having placenta percreta, and included mainly cystotomy (5.5% (95% CI, 0.6-15.1%) and 22.0% (95% CI, 5.4-45.5%), respectively). Urological complications occurred in 15.4% (95% CI, 8.1-24.6%) of cases undergoing a planned procedure and 24.6% (95% CI, 13.0-38.5%) of those undergoing an emergency intervention. In subanalysis of studies reporting on ≥ 12 cases per year, the incidence of urological complication was similar to that reported in the primary analysis. CONCLUSIONS Women undergoing surgery for PAS are at high risk of urological complication, mainly cystotomy. The incidence of these complications was particularly high in women described as having placenta percreta at birth and in those undergoing emergency surgical intervention. The high heterogeneity between the included studies highlights the need for a standardized protocol for the diagnosis of PAS to identify prenatal imaging signs associated with the increased risk of urological morbidity at delivery. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES Placenta accreta spectrum disorders (PAS) refers to a group of abnormalities in placental adhesion and invasion, which may lead to serious complications such as intractable postpartum hemorrhage. The use of low-level extra-abdominal aortic temporary block during cesarean section may reduce intraoperative bleeding in patients with PAS, but it may also cause ischemia-reperfusion injury. In this study, we intend to investigate the efficacy of low extra-abdominal aortic block in cesarean section for placental implantation disease and its effect on malondialdehyde (MDA) level and superoxide dismutase (SOD) activity, and analyze the severity of ischemia-reperfusion injury caused by them. METHODS Pregnant women with invasive placenta accreta spectrum disorders who delivered in the Department of Obstetrics and Gynecology of the Third Xiangya Hospital of Central South University from July 2017 to July 2021, were selected, and they were divided into 2 groups. Group A consisted of those who underwent low extra-abdominal aortic block during cesarean section (n=15) and group B consisted of those who did not undergo extra-abdominal aortic block (n=15). The intraoperative bleeding, blood transfusion, hysterectomy and complication rate, postoperative hospital stay and hospitalization expenses were compared between the 2 groups to analyze the efficacy of abdominal aortic block. The biochemical indexes related to ischemia-reperfusion, MDA content and total superoxide dismutase (T-SOD) activity, were measured at the corresponding time points in both groups. The time points of each test were: in group A, before the block of the low extra-abdominal aorta after delivery (A0), 0 h (A1, when the myometrium was started to be sutured), 0.5 h (A2), 2 h (A3), and 4 h (A4) after the open block; in group B, after delivery of the fetus (B0), 0 h (B1), 0.5 h (B2), 2 h (B3), and 4 h (B4) after the myometrium was started to be sutured. Total duration of abdominal aortic block in group A was also recorded. Both groups were observed for sings of edema, ischemia, necrosis and infection in the limbs after surgery. The severity of ischemia-reperfusion injury caused by abdominal aortic block were determined by detecting the relevant biochemical indexes at different moments of reperfusion. RESULTS The intraoperative bleeding and blood transfusion in group A were less than those in group B, and the difference was statistically significant (P<0.05). There was no significant difference in postoperative hospital stay and hospitalization expenses between the 2 groups (P>0.05). Surgical complications: in group A, the uterus was preserved in all cases, there was 1 bladder injury and 2 pelvic infections; while in group B, there was 1 hysterectomy, 3 bladder injuries, and 3 pelvic infections. Changes in T-SOD and MDA values: compared with A0 before block, the MDA level was significantly elevated in blood at time points A1, A2, and A3, while SOD activity was significantly decreased (P<0.05), and the 2 observed indexes basically returned to A1 level (ischemic period) at 4 h after open block (A4). There was no significant difference in the changes of T-SOD and MDA in group B (P>0.05). Comparison of T-SOD and MDA levels between group A and B: the difference of the 2 indexes was not statistically significant between A0 and B0 (P>0.05), MDA level was not statistically significant between A1 and B1, T-SOD activity at A1 was lower than B1, the difference was statistically significant, at the rest of the same time point, MDA level in group A were higher than that in group B, T-SOD activity in group A were lower than that in group B, the difference was statistically significant (P<0.05). No postoperative limb edema, ischemia, necrosis, or infection occurred in both groups. CONCLUSIONS Low-level extra-abdominal aortic block effectively reduces bleeding and transfusion during cesarean section for placenta accreta spectrum disorders, resulting in a transient MDA elevation and a decrease of SOD activity, which means causing transient ischemia-reperfusion injury without complications such as limb edema, ischemia, necrosis, and infection.

Abstract
INTRODUCTION A peripartum hysterectomy is typically performed as a lifesaving procedure in obstetrics to manage severe postpartum hemorrhage. Severe hemorrhages that lead to peripartum hysterectomies are mainly caused by uterine atony and placenta accreta spectrum disorders. In this study, we aimed to estimate the incidence, risk factors, causes and management of severe postpartum hemorrhage resulting in peripartum hysterectomies, and to describe the complications of the hysterectomies. MATERIAL AND METHODS Eligible women had given birth at gestational week 23+0 or later and had a postpartum hemorrhage ≥1500 mL or a blood transfusion, due to postpartum hemorrhage, at Oslo University Hospital, Norway, between 2008 and 2017. Among the eligible women, this study included those who underwent a hysterectomy within the first 42 days after delivery. The Norwegian Medical Birth Registry provided the reference group. We used Poisson regression to estimate adjusted incidence rate ratios with 95% confidence intervals to identify clinical factors associated with peripartum hysterectomy. RESULTS The incidence of hysterectomies with severe postpartum hemorrhage was 0.44/1000 deliveries (42/96313). Among the women with severe postpartum hemorrhage, 1.6% ended up with a hysterectomy (42/2621). Maternal age ≥40, previous cesarean section, multiple pregnancy and placenta previa were associated with a significantly higher risk of hysterectomy. Placenta accreta spectrum disorders were the most frequent cause of hemorrhage that resulted in a hysterectomy (52%, 22/42) and contributed to most of the complications following the hysterectomy (11/15 women with complications). CONCLUSIONS The rate of peripartum hysterectomies at Oslo University Hospital was low, but was higher than previously reported from Norway. Risk factors included high maternal age, previous cesarean section, multiple pregnancy and placenta previa, well known risk factors for placenta accreta spectrum disorders and severe postpartum hemorrhage. Placenta accreta spectrum disorders were the largest contributor to hysterectomies and complications.

Abstract
Background To compare the maternal and neonatal outcomes of placenta previa (PP) with and without coverage of a uterine scar in Foshan, China. Methods A retrospective cohort study comparing all singleton pregnancies with PP was conducted at a tertiary, university-affiliated medical center from 1 January 2012 to 31 April 2017 in Foshan, China. Demographic, clinical and laboratory data were extracted from electronic medical records (EMRs). Maternal and neonatal outcomes of PP with and without coverage of a uterine scar were compared by statistical method. Results There were 58,062 deliveries during the study period, of which 726 (1.25%) were complicated PP in singleton pregnancies and were further classified into two groups: the PP with coverage of a uterine scar group (PPCS, n=154) and the PP without coverage of a uterine scar group (Non-PPCS, n=572). Overall, premature birth (<37 weeks, 67.5% vs 54.8%; P=0.019), cesarean section (100% vs 97.6%; P=0.050), intraoperative blood loss >1000 mL (77.9% vs 16.0%; P<0.001) or >3000mL (29.9% vs 3.0%; P<0.001), bleeding within 2-24 hours after delivery (168.2±370.1 ml vs 49.9±58.4 ml; P<0.001), postpartum hemorrhage (48.7% vs 15.7%; P<0.001), transfusion (34.6% vs 16.1%; P<0.001), hemorrhage shock (7.8% vs 1.9%; P<0.001), hysterectomy (2.6% vs 0.5%; P=0.019), fetal distress (35.7% vs 12.1%; P<0.001) and APGAR score at 1 min (15.2% vs 7.1%; P=0.002) had a significant difference between PPCS group and Non-PPCS group. After grouping by whether complicated with placenta accreta spectrum disorders (PASD), we found that PPCS was significant associated with more intraoperative blood loss >1000mL, intraoperative blood loss >3000mL, bleeding within 2–24 hours after delivery and fetal distress than the Non-PPCS group. Conclusion The PPCS group had poorer maternal and neonatal outcomes than the Non-PPCS group after grouping by whether pregnancies complicated with PASD or with different placental positions.

Abstract
BACKGROUND Prenatal diagnosis of placenta accreta spectrum (PAS) disorders is difficult. Magnetic resonance imaging (MRI) has been shown to be a useful supplementary method to ultrasound. PURPOSE To investigate diffusion MRI (dMRI) based tractography as a tool for detecting PAS disorders, and to evaluate its performance compared with anatomical MRI. STUDY TYPE Prospective. POPULATION Forty-seven pregnant women in the third trimester with risk factors for PAS. FIELD STRENGTH/SEQUENCE Using fast imaging employing steady-state acquisition and high-angular resolution dMRI at 1.5 Tesla. ASSESSMENT Diagnosis of PAS was performed by three radiologists based on the dMRI-based feature of myometrial fiber discontinuity and on commonly used anatomical features including presence of dark band, discontinuous myometrium and bladder wall interruption. We evaluated the sensitivity, specificity, accuracy, and area-under-the-curve (AUC) of the individual features and established an integrated model with random forest analysis. STATISTICAL TESTS Maternal age and gestational age at scan were compared between PAS and control group using a t-test, and childbearing history was compared using a chi-squared test. The random forest model was employed to combine the anatomical and dMRI features with 5-fold cross-validation, and the weight of each feature was normalized to evaluate its importance in predicting PAS. RESULTS Based on surgical pathology reports, 16 out of 47 patients had confirmed PAS. The anatomical feature of dark bands and tractography marker achieved the highest AUC of 0.842 for predicting PAS, and the integrated anatomical and tractography features further improved the AUC of 0.880 with an accuracy of 87.2%. The tractography feature contributed most (30.1%) to the integrated model. DATA CONCLUSION Myometrial tractography demonstrated superior performance in detecting PAS. Moreover, the combination of dMRI-based tractography and anatomical MRI could potentially improve the diagnosis of PAS disorders in clinical practice. LEVEL OF EVIDENCE 2 TECHNICAL EFFICACY STAGE: 2.

We describe a novel surgical technique in 31 women with histopathologically confirmed placenta accreta spectrum (PAS) disorders managed by a multidisciplinary team using a prophylactic infrarenal abdominal aortic cross-clamping technique during caesarean hysterectomy. We conclude that this new surgical procedure is a relatively safe technique to potentially control operative blood loss. Our work may stimulate others to develop protocols assessing this innovative technique to improve the surgical outcome of PAS disorders.

Abstract
Abnormal invasion of placenta or placenta accreta spectrum disorders refer to the
penetration of the trophoblastic tissue through the decidua basalis into the
underlying uterine myometrium, the uterine serosa or even beyond, extending to
pelvic organs. It is classified depending on the degree of invasion into
placenta accreta (invasion <50% of the myometrium), increta (invasion >50%
of the myometrium) and percreta (invading the serosa and adjacent pelvic
organs). Clinical diagnosis is made intra-operatively; however, the confirmative
diagnosis can only be made after a histopathological examination. The incidence
of abnormal invasion of placenta has increased worldwide, mostly as a
consequence of the rise in caesarean section rates, from 1 in 2500 pregnancies
to 1 in 500 pregnancies. The importance of the disease is due to the increased
maternal and foetal morbidity and mortality. Foetal implications are mainly due
to iatrogenic prematurity, while maternal implications are mostly the increased
risk of obstetric haemorrhage and surgical complications. The average blood loss
is 3000–5000 mL, and up to 90% of the patients require a blood transfusion. An
accurate and timely antenatal diagnosis is essential to improve outcomes. The
traditional management of abnormal invasion of placenta has been a peripartum
hysterectomy; however, the increased incidence and the short- and long-term
consequences of a radical approach have led to the development of more
conservative techniques, such as the intentional retention of the placenta,
partial myometrial excision and the ‘Triple P procedure’. Irrespective of the
surgical technique of choice, women with a high suspicion or confirmed
abnormally invasive placenta should be managed in a specialist centre with
surgical expertise with a multi-disciplinary team who is experienced in managing
these complex cases with an immediate availability of blood products,
interventional radiology service, an intensive care unit and a neonatal
intensive care unit to optimize the outcomes.

Abstract
Objectives Investigation of mechanism related to excessive invasion of trophoblast cells in placenta accreta spectrum disorders (PAS) provides more strategies and ideas for clinical diagnosis and treatment. Materials and Methods Blood and placental samples were collected from included patients. The distribution and expression of CXCL12, CXCR4 and CXCR7 proteins in the paraffin of placental tissue in the included cases were analysed, and we analyse the downstream pathways or key proteins involved in cell invasion. Results Firstly, our results determined that CXCL12 and CXCR4/CXCR7 were increased in extravillous trophoblastic cell (CXCL12: P < .001; CXCR4: P < .001; CXCR7: P < .001), and the expression levels were closely related to the invasion depth of trophoblastic cells. Secondly, CXCL12 has the potential to become a biochemical indicator of PAS since the high expression of placental trophoblast CXCL12 may be an important source of blood CXCL12. Using lentivirus‐mediated RNA interference and overexpression assay, it was found that both chemokine CXCL12 and receptor CXCR4/CXCR7 are associated with regulation of trophoblast cell proliferation, migration and invasion. Further results proved that through the activating the phosphorylation and increasing the expression of MLC and AKT proteins in the Rho/rock, PI3K/AKT signalling pathway, CXCL12, CXCR4 and CXCR7 could up‐regulate the expression of RhoA, Rac1 and Cdc42 proteins to promote the migration and invasion of extravillous trophoblastic cell and ultimately formate the placenta accrete compare to the normal placenta. Conclusions Our research proved that trophoblasts may contribute to a PAS‐associated increase in CXCL12 levels in maternal blood. CXCL12 is not only associated with biological roles of PAS, but may also be potential for prediction of PAS.

Abstract
Objective To select a group at high risk of placenta accreta spectrum disorders (PAS) based on the data of serum screening in the first trimester. Methods A retrospective analysis of 48 patients with abnormal placental location (AP), including placenta previa (PP) only (n = 23) and PP and PAS (n = 25), was performed. Additionally, the AP group was divided depending on the blood loss volume: not higher than 1000 mL (LBL) (n = 29) and higher than 1000 mL (HBL) (n = 19); diagnostic term of PAS by ultrasound, data pregnancy-associated plasma protein-A (РAРР-A) and free β subunit of human chorionic gonadotropin (free β-hCG) multiple of median (MоM) at 11+0-13+6 weeks of gestation were evaluated. Serological markers were compared with the data of 39 healthy pregnant women with scar after previous cesarean section and normal placental location (control). Results The mean gestation at diagnostic term of PAS was 29 weeks. PAPP-Р MоM [mean (M) ± standard deviation (SD)] was: in controls, 1.07 ± 0.47; in the AP group, 1.59 ± 0.24; in PP, 1.91 ± 1.52; in PAS, 1.30 ± 0.85; in LBL, 1.37 ± 1.20; in HBL, 1.91 ± 1.24. The difference between control/AP, control/PP, control/PAS, PP/PAS, control/LBL, control/HBL and LBL/HBL was Р = 0.256, 0.145, 0.640, 0.311, 0.954, 0.025 and 0.09, respectively. Free β-hCG MoM (M ± SD) was: in controls, 1.08 ± 0.69, in AP, 1.31 ± 0.96; in PP, 1.46 ± 0.19; in PAS, 1.16 ± 0.65; in LBL, 1.30 ± 0.06; in HBL, 1.32 ± 0.78. Comparison of free β-hCG AP with controls and between subgroups did not reveal a significant difference. Conclusion Underestimation of PAS risk factors in pregnant women with AP leads to late diagnostics of pathology only in the third trimester. The assessment of the РAРР-A level in the first trimester may be helpful for the early prognosis of pathological blood loss at delivery for pregnant women with AP and for forming the high-risk group for PAS.

Abstract
OBJECTIVES To develop a prenatal ultrasound staging system for placenta accreta spectrum (PAS) disorders in women with placenta previa and to evaluate its association with surgical outcome, placental invasion and the clinical staging system for PAS disorders proposed by the International Federation of Gynecology and Obstetrics (FIGO). METHODS This was a secondary retrospective analysis of prospectively collected data from women with placenta previa. We classified women according to the following staging system for PAS disorders, based upon the presence of ultrasound signs of PAS in women with placenta previa: PAS0, placenta previa with no ultrasound signs of invasion or with placental lacunae but no evidence of abnormal uterus-bladder interface; PAS1, presence of at least two of placental lacunae, loss of the clear zone or bladder wall interruption; PAS2, PAS1 plus uterovescical hypervascularity; PAS3, PAS1 or PAS2 plus evidence of increased vascularity in the inferior part of the lower uterine segment potentially extending into the parametrial region. We explored whether this ultrasound staging system correlates with surgical outcome (estimated blood loss (EBL, mL), units of packed red blood cells (PRBC), fresh frozen plasma (FFP) and platelets (PLT) transfused, operation time (min), surgical complications defined as the occurrence of any damage to the bladder, ureters or bowel, length of hospital stay (days) and admission to intensive care unit (ICU)) and depth of placental invasion. The correlation between the present ultrasound staging system and the clinical grading system proposed by FIGO was assessed. Prenatal and surgical management were not based on the proposed prenatal ultrasound staging system. Linear and multiple regression models were used. RESULTS Two-hundred and fifty-nine women were included in the analysis. Mean EBL was 516 ± 151 mL in women with PAS0, 609 ± 146 mL in those with PAS1, 950 ± 190 mL in those with PAS2 and 1323 ± 533 mL in those with PAS3, and increased significantly with increasing severity of PAS ultrasound stage. Mean units of PRBC transfused were 0.05 ± 0.21 in PAS0, 0.10 ± 0.45 in PAS1, 1.19 ± 1.11 in PAS2 and 4.48 ± 2.06 in PAS3, and increased significantly with PAS stage. Similarly, there was a progressive increase in the mean units of FFP transfused from PAS1 to PAS3 (0.0 ± 0.0 in PAS1, 0.25 ± 1.0 in PAS2 and 3.63 ± 2.67 in PAS3). Women presenting with PAS3 on ultrasound had significantly more units of PLT transfused (2.37 ± 2.40) compared with those with PAS0 (0.03 ± 0.18), PAS1 (0.0 ± 0.0) or PAS2 (0.0 ± 0.0). Mean operation time was longer in women with PAS3 (184 ± 32 min) compared with those with PAS1 (153 ± 38 min) or PAS2 (161 ± 28 min). Similarly, women with PAS3 had longer hospital stay (7.4 ± 2.1 days) compared with those with PAS0 (3.4 ± 0.6 days), PAS1 (6.4 ± 1.3 days) or PAS2 (5.9 ± 0.8 days). On linear regression analysis, after adjusting for all potential confounders, higher PAS stage was associated independently with a significant increase in EBL (314 (95% CI, 230-399) mL per one-stage increase; P < 0.001), units of PRBC transfused (1.74 (95% CI, 1.33-2.15) per one-stage increase; P < 0.001), units of FFP transfused (1.19 (95% CI, 0.61-1.77) per one-stage increase; P < 0.001), units of PLT transfused (1.03 (95% CI, 0.59-1.47) per one-stage increase; P < 0.001), operation time (38.8 (95% CI, 31.6-46.1) min per one-stage increase; P < 0.001) and length of hospital stay (0.83 (95% CI, 0.46-1.27) days per one-stage increase; P < 0.001). On logistic regression analysis, increased severity of PAS was associated independently with surgical complications (odds ratio, 3.14 (95% CI, 1.36-7.25); P = 0.007), while only PAS3 was associated with admission to the ICU (P < 0.001). All women with PAS0 on ultrasound were classified as having Grade-1 PAS disorder according to the FIGO grading system. Conversely, of the women presenting with PAS1 on ultrasound, 64.1% (95% CI, 48.4-77.3%) were classified as having Grade-3, while 35.9% (95% CI, 22.7-51.6%) were classified as having Grade-4 PAS disorder, according to the FIGO grading system. All women with PAS2 were categorized as having Grade-5 and all those with PAS3 as having Grade-6 PAS disorder according to the FIGO system. CONCLUSION Ultrasound staging of PAS disorders is feasible and correlates with surgical outcome, depth of invasion and the FIGO clinical grading system. Copyright © 2019 ISUOG.

Abstract
Placenta accreta spectrum disorders, especially placenta percreta (PP) and placenta praevia (PLP), are major risk factors for massive obstetric haemorrhage which is a common cause of maternal morbidity and mortality in our environment. This risk becomes exponential and life-threatening when the two conditions co-exist in the same patient. Even in advanced countries with readily available expertise and state of the art resuscitative and supportive facilities, these conditions are associated with grave maternal and perinatal morbidity and mortality. We present a challenging case of PP co-existing with major PLP, which was diagnosed intraoperatively and the patient had total abdominal hysterectomy and bilateral internal iliac artery ligation to control haemorrhage.
