ABSTRACT
BACKGROUND: Placenta accreta spectrum disorder is an increasingly prevalent cause of maternal morbidity in developed countries. AIMS: This study aimed to review the management and outcomes of cases of placenta accreta spectrum, and compare blood loss and blood transfusion rates, over time after an institutional change in planned primary surgeon from gynaecological oncologists to experienced obstetricians. METHODS: This retrospective cohort study included all cases of suspected or confirmed placenta accreta spectrum disorder (PASD) between 1999 and 2021 at Monash Health. Data were collected by reviewing medical records to obtain baseline characteristics, details of surgical planning and management and major maternal morbidity outcomes over a 20-year period. The primary surgical lead was recorded as either gynaecological oncologist or experienced obstetricians. The primary outcomes were estimated maternal blood loss and number of units of blood transfused. RESULTS: A total of 88 patients were identified: 43 between 1999 and 2015 where gynaecological oncologists were the primary surgeon in 79% of cases and 45 between 2016 and 2021 where experienced obstetricians were the primary surgeon in 73.3% of cases. There was no statistically significant difference in the estimated blood loss between the two time periods (median: 2000 vs 2500 mL, P = 0.669). Hysterectomy rates were significantly reduced in the second time period, from 100 to 73.3%, P < 0.001. CONCLUSION: Management of cases of PASDs has improved over time with changes in antenatal diagnosis and perioperative management, and management by experienced obstetricians has similar maternal outcomes compared to those whose management includes the presence of gynaecological oncologists.

BACKGROUND: Placenta accreta spectrum (PAS) causes severe maternal morbidity and mortality. Antenatal diagnosis can optimise maternal outcomes and reduce the risk of complications. PAS cases where the placenta is not low lying are suggested to be more difficult to diagnose antenatally and are potentially associated with different outcomes. AIM: The aim was to compare factors associated with births in PAS pregnancies with and without placenta praevia at a single tertiary centre over 15 years. MATERIALS AND METHODS: A retrospective review of all births complicated by PAS was conducted from a site-specific database. Cases with and without a placenta praevia were analysed to compare differences in maternal risk factors, outcomes and histological diagnosis. RESULTS: Between June 2006 and July 2020 there were 134 cases of PAS, 106 with placenta praevia. Cases without praevia were less likely to have a history of previous caesarean section and to be admitted for delivery planning or with antepartum haemorrhage. A higher proportion of cases without praevia were delivered at term, with no overall difference in emergency or elective deliveries. There was a significantly lower rate of hysterectomy in the non-praevia group. The overall estimated blood loss was significantly lower in those without praevia. CONCLUSION: Suspected PAS without placenta praevia is at lower risk of hysterectomy and massive blood loss. The management approach can be tailored accordingly, with good operative outcomes with transverse abdominal and uterine incisions. Antenatal diagnosis can be difficult to accurately predict the degree of invasion, and a higher level of suspicion is required.

Placenta accreta spectrum (PAS) disorders have been on the rise in recent years with increasing caesarean rates. The purpose of this prospective observational study was to describe our detection rates and to review outcomes in PAS after the introduction of an institutional screening and management protocol. Twenty-one patients with suspected PAS over 5 years were identified. 20/21 patients had an accurate determination of placental invasion and positive correlation with surgical and histopathological examination. Early morbidity (massive haemorrhage) was found in 7/21 patients, whilst late morbidity (hospital readmission) was found in 5/21 patients. There were no maternal deaths and admissions to intensive therapy unit (ITU). In summary, our centre demonstrated a high antenatal detection rate for PAS using an evidence-based protocol. This has led to timely intervention by an experienced multidisciplinary team and excellent outcomes. Immediate and delayed postoperative counselling was effective for optimal patient understanding and experience.Impact StatementWhat is already known on this subject? With rising caesarean section rates, the incidence of placenta accreta spectrum (PAS) disorders is increasing. Despite this, most obstetricians have personally managed only a small number of patients with PAS. Moreover, there appears to be some debate over the optimal diagnostic and management strategy.What do the results of this study add? As the incidence increases, development of institutional screening and management protocol is a necessity for large units. Timely diagnosis, extensive pre and postoperative counselling and multidisciplinary teamwork ensure reduced early and late morbidity.What are the implications of these findings for clinical practice and/or further research? Evidence based screening protocols for PAS disorders reduce the likelihood of undiagnosed cases and should be developed in every unit. Consideration must also be given to standardisation of the diagnostic and management protocols, including contingency plan for emergencies.

Background and Objectives: Acute urologic complications, including bladder and/or ureteric injury, are rare but known events occurring at the time of caesarean section (CS). Delayed or inadequate management is associated with increased morbidity and poor long-term outcomes. We conducted this study to identify the risk factors for urologic injuries at CS in order to inform obstetricians and patients of the risks and allow management planning to mitigate these risks. Materials and Methods: We reviewed all cases of urological injuries that occurred at CS surgeries in a tertiary university centre over a period of four years, from January 2016 to December 2019. To assess the risk factors of urologic injuries, a case-control study of women undergoing caesarean delivery was designed, matched 1:3 to randomly selected women who had an uncomplicated CS. Electronic medical records and operative reports were reviewed for socio-demographic and clinical information. Descriptive and univariate analyses were used to characterize the study population and identify the risk factors for urologic complications. Results: There were 36 patients with urologic complications out of 14,340 CS patients, with an incidence of 0.25%. The patients in the case group were older, had a lower gestational age at time of delivery and their newborns had a lower birth weight. Prior CS was more prevalent among the study group (88.2 vs. 66.7%), as was the incidence of placenta accreta and central praevia. In comparison with the control group, the intraoperative blood loss was higher in the case group, although there was no difference among the two groups regarding the type of surgery (emergency vs. elective), uterine rupture, or other obstetrical indications for CS. Prior CS and caesarean hysterectomy were risk factors for urologic injuries at CS. Conclusions: The major risk factor for urological injuries at the time of CS surgery is prior CS. Among patients with previous CS, those who undergo caesarean hysterectomy for placenta previa central and placenta accreta are at higher risk of surgical haemostasis and complex urologic injuries involving the bladder and the ureters.

PURPOSE: To compare n-butyl cyanoacrylate (NBCA) and gelatine sponge (GS) as embolic materials for prophylactic pelvic arterial embolisation during caesarean hysterectomy for placenta accreta spectrum (PAS). MATERIAL AND METHODS: This retrospective study comprised 12 women (age range, 23-42 years; mean, 34.1 years) who underwent caesarean hysterectomy for PAS. Following caesarean delivery, bilateral uterine and non-uterine parasitic arteries were embolized with GS in the first four cases (GS group) and primarily with NBCA mixed with iodized oil in the subsequent eight cases (NBCA group). Procedure time for embolisation and hysterectomy and total blood loss were compared between the two groups using Welch's t-test. RESULTS: Although procedure time for embolisation tended to be longer in the NBCA group than in the GS group (111 ± 47 min versus 71 ± 32 min, p=.11), that for hysterectomy was significantly reduced in the NBCA group when compared to the GS group (158 ± 42 min versus 236 ± 39 min, p=.02). Total blood loss was significantly lower in the NBCA group than in the GS group (1375 ± 565 mL versus 2668 ± 587 mL, p=.01). CONCLUSION: Procedure time for hysterectomy and total blood loss during caesarean hysterectomy can be reduced by using NBCA instead of GS in prophylactic pelvic arterial embolisation for PAS.

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.

BACKGROUND: Emergency Obstetric Hysterectomy (EOH) is removal of the uterus due to life threatening conditions within the puerperium. This life saving intervention is associated with life threatening complications. In our setting, little is known on EOH. OBJECTIVES: To determine the prevalence, indications and outcomes of emergency obstetric hysterectomy while comparing both postpartum hysterectomy and caesarean hysterectomy. METHODS: A 5-year hospital-based retrospective cohort study involving medical records of patients who underwent emergency obstetric hysterectomies between 1st January 2015 and 31st December 2019, was carried out at the Bafoussam Regional Hospital (BRH) from 1st February 2020 to 30th April 2020. Cases were classified as caesarean hysterectomy (CH) or postpartum hysterectomy (PH). Epidemiological data, indications, and complications of EOH were collected and analyzed in EPI-INFO 7.2.2.1. The chi-squared test was used to compare the two groups, and bivariate analysis was used to identify indicators of adverse outcomes of EOH. Statistical significance was set at p < 0.05. RESULTS: There were 30 cases of emergency obstetric hysterectomy (24 caesarean hysterectomies and 6 postpartum hysterectomies), giving a prevalence rate of 3.75 per 1000 deliveries. The most common indication for CH, was intractable postpartum haemorrhage and uterine rupture (33.33% each), while abnormal placentation (50%) was commonly indicated for PH. Anaemia (both groups) (p = 0.013) and sepsis (PH group only, 33.33%) (p = 0.03) were the most statistically significant complications of EOH respectively. Absence of blood transfusion prior to surgery (p = 0.013) and prolonged surgery lasting 2 or more hours (p = 0.04), were significantly associated with a negative clinical outcome. CONCLUSION: The prevalence of EOH is high. There were no differences in the sociodemographic profile, risk factors and indications of both groups. PH group was more likely to develop sepsis as complication. Lack of blood transfusion prior to surgery and prolonged surgeries were significantly associated to complication. Meticulous care and timely recognition of negative prognostic factors of delivery as well as those of EOH will help improve maternal outcomes of pregnancy.

PURPOSE: Placenta accreta spectrum (PAS) disorders can cause major intrapartum haemorrhage. The optimal management approach is not yet defined. We analysed available cases from a tertiary perinatal centre to compare the outcome of different individual management strategies. METHODS: A monocentric retrospective analysis was performed in patients with clinically confirmed diagnosis of PAS between 07/2012 and 12/2019. Electronic patient and ultrasound databases were examined for perinatal findings, peripartum morbidity including blood loss and management approaches such as (1) vaginal delivery and curettage, (2) caesarean section with placental removal versus left in situ and (3) planned, immediate or delayed hysterectomy. RESULTS: 46 cases were identified with an incidence of 2.49 per 1000 births. Median diagnosis of placenta accreta (56%), increta (39%) or percreta (4%) was made in 35 weeks of gestation. Prenatal detection rate was 33% for all cases and 78% for placenta increta. 33% showed an association with placenta praevia, 41% with previous caesarean section and 52% with previous curettage. Caesarean section rate was 65% and hysterectomy rate 39%. In 9% of the cases, the placenta primarily remained in situ. 54% of patients required blood transfusion. Blood loss did not differ between cases with versus without prenatal diagnosis (p = 0.327). In known cases, an attempt to remove the placenta did not show impact on blood loss (p = 0.417). CONCLUSION: PAS should be managed in an optimal setting and with a well-coordinated team. Experience with different approaches should be proven in prospective multicentre studies to prepare recommendations for expected and unexpected need for management.

OBJECTIVES: To assess maternal and fetal morbidity associated with placenta previa and morbidly adherent placenta (MAP). METHODS: All patients with placenta previa who delivered in services hospital from April 1, 2017 to March 31, 2019 were included. Maternal and fetal outcomes were compared amongst patients with placenta previa and MAP. RESULTS: Total of 8002 patients delivered with 152 (1.9%) diagnosed as placenta previa and 56 (36.8%) amongst them had MAP. One hundred thirty-one out of One hundred fifty-two (86.1%) of our patients were booked. Increased number of caesarean section, multi parity and anterior placenta had significant association with MAP (p<0.0001). Maternal morbidity in terms of postpartum hemorrhage >2000ml, caesarean hysterectomy, number of blood transfusions, bladder injury, need for ICU admission was significantly more in patients with MAP (p<0.0001). Case fatality was 3% with two maternal deaths in MAP and none in placenta previa. Fetal outcome was good in both groups as gestational age at delivery was 36 weeks or more, birth weight was ≥ 2.5 kg and >6 APGAR score (p<0.05). Two neonatal deaths occurred in MAP and one in placenta previa owing to prematurity. CONCLUSION: MAP is a dreadful complication of placenta previa with increased maternal morbidity. Regular antenatal care with adequate arrangement of blood transfusion and multidisciplinary approach can reduce maternal mortality.
ABSTRACT
OBJECTIVE: The incidence of placenta accreta spectrum (PAS) has risen over the past decades, primarily in response to increasing Caesarean section rates. The surgical management of PAS is associated with significant morbidity, including hemorrhage and intensive care unit (ICU) admission. This study sought to evaluate the surgical outcomes of a PAS operative approach. METHODS: A single-centre retrospective chart review of all Caesarean hysterectomies for PAS by an assigned surgeon over a 16-year period was performed. Surgical outcomes were described (Canadian Task Force Classification II-2). RESULTS: The described surgical approach involves a midline skin incision, high midline hysterotomy, a rapid single-layer uterine closure with no placental removal attempt, constant cephalad uterine traction, and liberal choice of subtotal hysterectomy. A total of 47 patients were included: 19 (40.4%) with placenta accreta, 14 (29.8%) with placenta increta, and 14 (29.8%) with placenta percreta. Mean estimated blood loss was 1416 ± 699 mL, and mean operative time was 112 ± 49 minutes. Overall, 16 patients (34.0%) required blood transfusion, and 4 patients (8.5%) required ICU admission. The average hospitalization was 5.2 days, with no re-admission within 30 days. The use of internal iliac balloons did not result in a difference in blood loss or operative time (P > 0.05). Patients with placenta percreta had significantly more blood loss (Pâ¯=â¯0.02) and longer operative time (Pâ¯=â¯0.007) compared with those with placenta accreta and increta. CONCLUSION: The current surgical model for planned Caesarean hysterectomy for PAS exhibits a low complication rate. Further research is needed for developing a standardized approach to the management of PAS.

BACKGROUND: Placenta accreta spectrum (PAS) disorders are a potentially life-threatening complication of pregnancy that demand coordinated interdisciplinary care to achieve safer outcomes. The rising incidence of this disease is due to a growing number of uterine surgical procedures, including the rising incidence of pregnancy following Caesarean section. OBJECTIVE: To provide current evidence-based guidelines on the optimal methods used to effectively screen, diagnose, and manage PAS disorders. METHODS: Members of the guideline committee were selected on the basis of their ongoing expertise in managing this condition across Canada and by practice setting. The committee reviewed all available evidence in the English medical literature, including published guidelines, and evaluated diagnostic tests, surgical procedures, and clinical outcomes. EVIDENCE: Published literature, including clinical practice guidelines, was retrieved through searches of Medline and The Cochrane Library to March 2018 using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized controlled trials, and observational studies written in English. Searches were updated on a regular basis and incorporated in the guideline to July 2018. VALUES: The quality of evidence in this document was graded using the criteria described in the Report of the Canadian Task Force on Preventive Health Care. RESULTS: This document reviews the evidence regarding the available diagnostic and surgical techniques used for optimal management of women with suspected PAS disorders, including anaesthesia and practical considerations for interdisciplinary care. BENEFITS, HARMS, AND COSTS: Implementation of the guideline recommendations will improve awareness of this disease and increase the proportion of affected women receiving interdisciplinary care in regional centres. CONCLUSIONS: Interdisciplinary team-based care providing accurate diagnostic services, coordinated planning, and safer surgery deliver effective care with improved clinical outcomes in comparison with alternative management. SUMMARY STATEMENTS: RECOMMENDATIONS.

INTRODUCTION: Placenta accreta spectrum (PAS) covers a spectrum of placental adherence abnormalities: placenta accreta, increta and percreta. PAS is associated with significant maternal morbidity and mortality. Studies have shown the importance of multidisciplinary teamwork in the management of PAS. AIM: This study was designed to describe the maternal and neonatal morbidity and mortality associated with PAS in our centre over a ten-year period. METHODS: A retrospective cohort study was conducted of pregnancies complicated by PAS between February 2006 and January 2016 at Flinders Medical Centre (FMC), South Australia. Electronic and medical records were examined to obtain patient demographics, antenatal and surgical, findings and postnatal outcomes. RESULTS: There were 67 PAS cases with an overall incidence of 2.3 per 1000 deliveries. Three cases were excluded due to incomplete information. Of the remaining 64 cases, 56 women were antenatally diagnosed. Sixty cases were confirmed to be invasive at delivery; 28 accreta (superficial) and 32 increta/percreta (deep) cases. The four cases with no invasion at delivery were suspected antenatally to have PAS. The median (Q1, Q3) number of caesarean sections in this cohort was 2 (1, 3). Deep invasion is significantly associated with increased bleeding, intensive care unit admission, surgical complications and an extended postpartum stay. CONCLUSION: The incidence of PAS at FMC is high as it is the state's tertiary referral centre. While PAS is associated with increased morbidity, thorough perioperative planning by a multidisciplinary team is crucial for excellent patient outcomes.

OBJECTIVE: To evaluate the prevalence and management strategies of placenta accreta spectrum disorders at a tertiary teaching hospital. METHODS: The retrospective cross-sectional study was conducted at Al-Yarmouk Teaching Hospital, Baghdad, Iraq, and comprised record of patients diagnosed with placenta accreta spectrum disorders between January 2014and December 2017. Different management approached employes were noted and data was analysed using SPSS 22. RESULTS: Of the 7312 deliveries during the four-year period, there were 102(1.4%) cases of placenta accreta spectrum disorders. Of them, 83(81.3%) were managed by definitive surgery and 19(18.7%) with conservative surgery. The prevalence of placenta accreta spectrum disorders was 162.4 per 100,000 women in 2014, 266.7 in 2015, 382.3 in 2016, and 191.5 per 100 000 women in 2017. All the cases related to multiparous women with previous history of caesarean section. CONCLUSIONS: The incidence of placenta accreta spectrum disorders was high in our centre.

OBJECTIVE: To evaluate urological interventions in patients with placental adhesive disorders in our collaborative experience at a tertiary referral centre. PATIENTS AND METHODS: We performed a retrospective analysis of a prospectively collected data set, consisting of all women that presented with placental adhesive disorders at the Royal Women's Hospital from August 2009 to September 2013. Patients who required urological intervention were identified and perioperative details were retrieved. RESULTS: Of the 49 women that presented with placental adhesive disorders, 36 (73.5%) underwent urological interventions. The patients were divided into three groups: planned hysterectomy (37 patients), planned conservative management (five) and undiagnosed placenta percreta (seven). In the planned hysterectomy group, 29 patients underwent preoperative cystoscopy and ureteric catheter placement. In 10 patients (34%), the placenta partially invaded the bladder and/or ureter, requiring urological repair. In the conservative management group, four underwent preoperative cystoscopy and ureteric catheter placement, and one case required closure of a cystotomy. Of the seven patients with undiagnosed percreta, two were noted to have bladder involvement requiring repair at the time of Caesarean hysterectomy. CONCLUSION: Patients with placental adhesive disorders frequently require urological intervention to prevent or repair injury to the urinary tract. These cases are best managed in specialist centres with multidisciplinary expertise including urologists and interventional radiologists.

UNLABELLED: Placenta praevia/accreta is associated with significant maternal morbidity and mortality and is a common cause of obstetric hysterectomy. This paper describes posterior retrograde abdominal hysterectomy, a new surgical technique for caesarean hysterectomy, in 11 women with placenta percreta, increta or accreta There were no intraoperative or postoperative maternal complications, and only one fetus required admission to the neonatal unit, for prematurity. Our technique in placenta praevia/accreta allows easy identification of the vagina and early uterine devascularisation, as well as safe resection of the involved urinary bladder in women with placenta percreta showing bladder penetration. Analytical studies are needed to confirm our findings. TWEETABLE ABSTRACT: Posterior retrograde abdominal hysterectomy in women with placenta praevia/accreta may enable safer surgery.

Abnromalities of placentation, including placenta accreta, represent a major source of morbidity and mortality among women. Traditional management consists of peripartum hysterectomy at the time of delivery, although more conservative treatments have also been developed recently. In this review we describe the available literature describing the operative approach and considerations for management of women with placenta accreta.

The incidence of placental attachment disorders continues to increase with rising caesarean section rates. Antenatal diagnosis helps in the planning of location, timing and staffing of delivery. In at-risk women grey-scale ultrasound is quite sensitive, although colour ultrasound is the most predictive. Magnetic resonance imaging can add information in some limited instances. Patients who have had a previous caesarean section could benefit from early (before 10 weeks) visualisation of the implantation site. Current data refer only to placentas implanted in the lower anterior uterine segment, usually over a caesarean section scar.

Caesarean scar pregnancy (CSP) occurs when the gestational sac implants in the region of a scar from a previous caesarean delivery. CSP can lead to life-threatening complications, including severe haemorrhage, uterine rupture, placenta accreta spectrum (PAS) and hysterectomy. A 40-year-old woman with one previous caesarean was referred to the specialist centre at 17+1 weeks of gestation with concerns about CSP. At 19 weeks, she was admitted with abdominal pain. Due to raised body habitus, accurate ultrasound assessment was challenging, necessitating reliance on magnetic resonance imaging (MRI). The patient desired to continue the pregnancy, but due to pain and concerns about uterine rupture she consented to a laparotomy to potentially terminate the pregnancy. Findings during the laparotomy were reassuring, leading to the decision not to terminate the pregnancy. The patient remained hospitalised until delivery by caesarean-hysterectomy at 33+6 weeks. Histopathology confirmed the PAS diagnosis. This case highlights the importance of achieving early diagnosis and obtaining clear sonographic findings. It emphasises the pitfalls of relying on MRI due to its tendency to over-diagnose severity. It emphasises the urgency for improved training in this domain. Early sonographic diagnosis allows safer performance of termination of pregnancy. It also provides women who continue with the pregnancy useful prognostic signs to facilitate decisions on the optimal gestation for delivery. Determining optimal conservative management for CSP remains an ongoing challenge. This case emphasises the importance of multidisciplinary discussion, comprehensive patient counselling and involving patients in their care planning, to create an individualised and adaptable treatment plan.
ABSTRACT
Background: The placenta accreta spectrum is a complex disorder characterized by abnormal invasion of the placenta into the uterine wall, posing a significant risk of life-threatening haemorrhage for patients. Its incidence is on the rise, largely attributed to the increasing rates of caesarean sections. Management of this spectrum involves a multidisciplinary approach, although standardized protocols are not yet established. While caesarean hysterectomy remains the standard Gold, several adjunctive treatments have emerged in recent years to mitigate bleeding risk and associated morbidity. Among these, prophylactic occlusion balloons placed in the internal iliac arteries have shown promise. The aim of our study is to demonstrate the effect of prophylactic occlusion balloons in both uterine iliac arteries in the management of placental accreta spectrum disorders. Methods: A retrospective monocentric cohort study was conducted in the Department "C" of Gynaecology and Obstetrics at the Maternity Center of Tunis. The study spanned three years, from January 2nd, 2020, to December 31st, 2022. The study population consisted of two groups: Control Group (CG) comprised patients who underwent caesarean hysterectomy without internal-iliac prophylactic occlusion balloons, and Occlusion balloons of both internal iliac arteries Group (OBIIAG) included patients who underwent caesarean hysterectomy with internal-iliac prophylactic occlusion balloons. Results: A total of 38 patients were included in the study, all of whom exhibited similar epidemiological characteristics and comparable personal and obstetric histories. The most prevalent risk factor among the patients was a history of caesarean section (92%). On average, patients were diagnosed at 30 weeks of gestation, with third-trimester bleeding being the most common presentation (71% of cases). The median gestational age at delivery was between 36 and 37 weeks. We observed a significant difference in blood loss between the two groups (2888 ml in the control group and 1828 ml in the group with internal-iliac prophylactic occlusion balloons, p < 0.05). Implementation of this technique resulted in a reduced need for massive transfusions (p < 0.01) and shorter operating times (126 min for the control group and 92 min for the group with internal-iliac prophylactic occlusion balloons; p = 0.04). There were no significant differences in morbidity between the two groups. Conclusion: The intra-iliac prophylactic occlusion balloons can help reduce the risk of hemorrhage and the morbidities that come with the placenta accreta spectrum disorder.
ABSTRACT
OBJECTIVE: The incidence of placenta accreta spectrum (PAS) is rising rapidly due to the global surge in Caesarean delivery. It is associated with significant maternal morbidity and mortality. It is usually managed with Caesarean hysterectomy. However, uterine preserving surgeries can have advantages over Caesarean hysterectomy and intentional placental retention techniques. STUDY DESIGN: We present a modified technique of uterine preserving surgery that uses a safe approach for placental bed surgical devascularization. This is followed by resection of the invaded uterine segment and uterine wall reconstruction. RESULTS: The technique was used in the management of 20 patients with antenatally suspected PAS that were confirmed at laparotomy. It was successful in preserving the uterus in 18/20 (90 %) women. The mean intraoperative blood loss in was 1305 CC (SD: +361.6) with a mean operative time of 123 min (SD: ±38.7). There was only one urinary bladder injury and no other maternal morbidity. CONCLUSION: Our surgical technique is safe and may be useful for conservative surgical management of PAS, particularly in low- and middle-income countries, where access to complex resources, such as interventional radiology, is limited.
