PLACENTA PERCRETA WITH BLADDER INVASION AS A CAUSE OF LIFE THREATENING HEMORRHAGE

Three-dimensional volume rendering ultrasound for assessing placenta accreta spectrum severity and discriminating it from simple scar dehiscence

BACKGROUND

Prenatal ultrasound discrimination between placenta accreta spectrum and scar dehiscence with underlying nonadherent placenta is challenging both prenatally and intraoperatively, which often leads to overtreatment. In addition, accurate prenatal prediction of surgical difficulty and morbidity in placenta accreta spectrum is difficult, which precludes appropriate multidisciplinary planning. The advent of advanced 3-dimensional volume rendering and contrast enhancement techniques in modern ultrasound systems provides a comprehensive prenatal assessment, revealing details that are not discernible in traditional 2-dimensional imaging.

OBJECTIVE

This study aimed to evaluate the use of 3-dimensional volume rendering ultrasound techniques in determining the severity of placenta accreta spectrum and distinguishing between placenta accreta spectrum and scar dehiscence with underlying nonadherent placenta.

STUDY DESIGN

A prospective, cohort study was conducted between July 2022 and July 2023 in the fetal medicine unit of Dr Soetomo Academic General Hospital, Surabaya, Indonesia. All pregnant individuals with anterior low-lying placenta or placenta previa with a previous caesarean section who were referred with suspicion of placenta accreta spectrum were consented and screened using the standardised 2-dimensional and Doppler ultrasound imaging. Additional 3-dimensional volumes were obtained from the sagittal section of the uterus with a filled urinary bladder. These were analyzed by rotating the region of interest to be perpendicular to the uterovesical interface. The primary outcomes were the clinical and histologic severity in the cases of placenta accreta spectrum and correct diagnosis of dehiscence with nonadherent placenta underneath. The strength of association between ultrasound and clinical outcomes was determined. Multivariate logistic regression analyses and diagnostic testing of accuracy were used to analyze the data.

RESULTS

A total of 70 patients (56 with placenta accreta spectrum and 14 with scar dehiscence) were included in the analysis. Multivariate logistic regression of all 2-dimensional and 3-dimensional signs revealed the 3-dimensional loss of clear zone (P<.001) and the presence of bridging vessels on 2-dimensional Doppler ultrasound (P=.027) as excellent predictors in differentiating scar dehiscence and placenta accreta spectrum. The 3-dimensional loss of clear zone demonstrated a high diagnostic accuracy with an area under the curve of 0.911 (95% confidence interval, 0.819-1.002), with a sensitivity of 89.3% (95% confidence interval, 78.1-95.97%) and specificity of 92.9% (95% confidence interval, 66.1-99.8%). The presence of bridging vessels on 2-dimensional Doppler demonstrated an area under the curve of 0.848 (95% confidence interval, 0.714-0.982) with a sensitivity of 91.1% (95% confidence interval, 80.4-97.0%) and specificity of 78.6% (95% confidence interval, 49.2-95.3%). A subgroup analysis among the placenta accreta spectrum group revealed that the presence of a 3-dimensional disrupted bladder serosa with obliteration of the vesicouterine space was associated with vesicouterine adherence (P<.001).

CONCLUSION

Three-dimensional volume rendering ultrasound is a promising tool for effective discrimination between scar dehiscence with underlying nonadherent placenta and placenta accreta spectrum. It also shows potential in predicting the clinical severity with urinary bladder involvement in cases of placenta accreta spectrum.

Placenta Percreta Managed by Ultrasound-Guided Vertical Transfundal Uterine Incision with Hysterectomy: Case Report

Placenta accreta spectrum is an obstetrics complication in which the placenta has abnormally adhered to the decidua and uterine wall. Placenta percreta is the rarest and sternest variant of accreta syndrome. In this study, we present a case of placenta percreta where we have done ultrasound-guided trans fundal vertical uterine incision to deliver a healthy fetus and subsequent cesarean hysterectomy. Antepartum diagnosis, involvement of a multidisciplinary team, appropriate counseling of women and their families, ultrasound guidance for placental margin demarcation, and vertical transfundal uterine incision can be considered for patients with placenta percreta.

Bladder involvement in placenta accreta spectrum disorder with placenta previa: MRI findings and outcomes correlation

BACKGROUND

Placental accreta spectrum (PAS) disorder with bladder involvement can be associated with maternal and neonatal morbidity. Magnetic resonance imaging (MRI) may provide accurate preoperative diagnoses.

OBJECTIVE

This study had 2 aims: to retrospectively review the MRI findings for bladder involvement in PAS with placental previa and to correlate bladder involvement with maternal and neonatal outcomes.

MATERIALS AND METHODS

MRI images of 48 patients with severe PAS (increta and percreta) with placenta previa/low-lying placenta were evaluated by 2 experienced radiologists blinded to the final diagnoses. Nine MRI findings and stepwise logistic regression analysis were assessed to identify predictive MRI findings for bladder involvement. The correlations between PAS patients with bladder involvement and clinical outcomes were analyzed using Fisher's exact test.

RESULTS

Of the 48 patients, 27 did not have bladder involvement, while 21 did. Logistic regression analysis identified 2 predictive MRI features for bladder involvement. They were abnormal vascularization (OR,6.94; 95 %CI,1.05-45.75) and loss of the chemical shift line at the uterovesical interface (OR, 4.41; 95 %CI, 0.63-30.98). The sensitivity and specificity of the combined MRI features were 38.1 % and 100 %, respectively (p = 0.001). A significant correlation was found between bladder involvement and massive blood loss during surgery (p = 0.022).

CONCLUSIONS

PAS with bladder involvement was significantly correlated with massive surgical blood loss. Prenatally, the disorder was predicted with high specificity by the combination of loss of chemical shift artifacts in the steady-state free precession sequence and abnormal vascularization at the uterovesical interface on MRI.

Monstrous Invasion of Placenta Percreta and Previa: Multidisciplinary Management of a Case, the Role of a Urologist, and a Literature Review

In rare situations, pregnant women may experience life-threatening bleeding due to the placenta’s aberrant invasion of the bladder. A 28-year-old pregnant female with two previous cesarean deliveries presented with the chief complaint of abdominal pain at the earlier scar site. Ultrasound imaging was suggestive of placenta percreta with bladder invasion. The patient underwent elective cesarean section with a uterine-preservation strategy. A healthy male baby was delivered by classical cesarean section, and bilateral uterine artery ligation was done. The patient developed severe postoperative hemorrhage, for which she was re-explored, and the urology team was called for intraoperative assistance. The area of placental invasion into the bladder was resected entirely with bladder reconstruction. Placenta percreta is a life-threatening condition that can involve adjacent uterine structures. Successful management involves a multidisciplinary strategy involving experienced obstetricians, urologists, anesthesiologists, blood bank teams, and neonatologists.

Pregnancy-related acute kidney injury and urological comorbidities in morbidly adherent placenta: A potential challenge to AKI-0by25

Pregnancy-related acute kidney injury (PRAKI) and urological complications can significantly increase the maternal morbidity and mortality, and morbidly adherent placenta (MAP) has been found to increase the risk of both. This is a four-year prospective study, conducted on patients with MAP. Baseline parameters (demographic/antenatal/perinatal), operative details (obstetric/urological/hemostatic), peri-operative complications (AKI/urological), and maternal/fetal outcomes were studied till six weeks after delivery. Statistical analysis was done using IBM SPSS Statistics version 21.0, and P <0.05 was considered statistically significant. Out of the 5475 deliveries conducted in the study period, 64 had adherent placentation. AKI occurred in 39.1% of patients, with severe AKI (AKIN-2, 3) in 10.9%, and significantly higher incidence in placenta percreta (P = 0.021, relative risk [RR] - 2.34), urological injuries (P = 0.001, RR - 2.86), and high blood loss (P = 0.001) on univariate analysis, but placenta percreta was the most statistically significant factor P = 0.049) on multivariate analysis. Urological involvement/injuries requiring intervention were encountered in 22 patients, with statistically significantly high incidence in placenta previa (P = 0.023, RR - 1.62), placenta percreta (P = 0.000, RR - 17.18), and patients undergoing hysterectomy (P = 0.000, RR - 2.01) on univariate analysis, but placenta percreta was most statistically significantly implicated on multivariate analysis (P = 0.017). AKI and urological injuries significantly increased the need for intensive care and days of hospitalization. On six-week follow-up, all AKI patients recovered completely; no urinary leak or vesico-vaginal fistula was seen in urologically intervened patients and no maternal mortality occurred. There is an alarmingly high incidence of PRAKI and urological complications in MAP, posing a great threat to their worldwide improving statistics. Awareness of this condition among renal fraternity can significantly improve the maternal renal and overall prognosis.

Surgical strategies for placenta percreta invading the bladder and review of literature

Background

Major obstetric hemorrhage is the leading cause of maternal morbidity and mortality. In rare cases, life-threatening hematuria in pregnant women may result from invasion of the bladder by the placenta. We present our experience with 18 cases of placenta percreta with suspected bladder invasion.

Methods

It is a retrospective single-center study conducted over a period of 3 years. Total 18 patients of radiologically diagnosed placenta percreta were included in the study. All patients who are at risk for placenta percreta underwent prenatal sonograms. Patients of Placenta Accreta Spectrum presenting electively also underwent MRI pelvis. Elective patients who were high risk of placenta percreta underwent bilateral placement of the balloon catheter in internal iliac artery. In case of doubt regarding bladder invasion, patient underwent anterior cystotomy and posterior wall of the bladder was examined and proximity of the ureteric orifice to the placenta and amount of involvement of bladder wall was assessed. Ureteric catheter placement was used as adjuncts depending on the proximity of placental invasion with ureteric orifice. Postoperative outcomes in the form of maternal morbidity, maternal mortality, fetal mortality, postoperative bleeding, bladder status, vesicovaginal fistula, bladder capacity were all evaluated.

Results

In our series, 17 cases all cases were diagnosed preoperatively by antenatal ultrasound and MRI. Only one patient presented with hematuria. Only in one patient, we attempted separation of placenta from bladder wall, and it resulted in profuse bleeding, and in rest, we excised the involved bladder. Partial cystectomy was done in 33.4% patients, 27% patients required bilateral placement of ureteric catheter due to proximity to the ureteric orifice. 33.4% patient underwent bilateral internal iliac artery ligation or balloon placement. Clot evaluation was needed in one patient. Intraoperatively—39% patients had uterus adhered to the bladder but no placental invasion into the bladder. One patient was managed with obstetric hysterectomy and methotrexate followed by clot evacuation and bilateral internal iliac artery ligation at a later date. One (5.6%) patient developed vesicovaginal fistula in postoperative period. There was one (5.6%) maternal mortality with no fetal mortality. On follow-up, patient had good bladder capacity, 3 weeks after the surgery.

Conclusion

MRI done preoperatively can help us guide regarding the extent or severity of placental invasion. Intraoperatively, anterior cystostomy should be done in suspected placenta percreta. Grade I or II accrete/percreta patients can be managed conservatively. Partial cystectomy with placement of bilateral ureteric catheter is safer and less morbid approach in tackling placenta percreta invading the bladder with mucosal involvement.

MRI prognosticators for adverse maternal and neonatal clinical outcome in patients at high risk for placenta accreta spectrum (PAS) disorders

BACKGROUND

Placenta accreta spectrum (PAS) disorders may be associated with significant mortality and morbidity for both mother and fetus.

PURPOSE/HYPOTHESIS

To identify MRI risk factors for poor peripartum outcome in gravid patients at risk for PAS.

STUDY TYPE

Prospective.

POPULATION

One hundred gravid women (mean age: 34.9 years) at third trimester, with placenta previa.

FIELD STRENGTH/SEQUENCE

T₂ -SSTSE (single-shot turbo spin echo), T₂ -TSE, T₁ -TSEFS (TSE images with fat-suppression) at 1.5T.

ASSESSMENT

Fifteen MRI features considered indicative of PAS were recorded by three radiologists and were tested for any association with the following adverse peripartum maternal and neonatal events: increased operation time, profound blood loss, hysterectomy, bladder repair, ICU admission, prematurity, low birthweight, and 5-minute APGAR score <7.

STATISTICAL TESTS

Kappa (K) coefficients were computed as a measure of agreement between intraoperative information/histology and MRI results as well as for interobserver agreement; chi-square and Fisher's exact tests were used to explore the association of the MRI signs with clinical complications. A score was calculated by adding all recorded MRI signs and its predictive ability was tested using receiver operating characteristic (ROC) analysis, against all complications, separately; odds ratios (ORs) for optimal cutoffs were determined with logistic regression analysis.

RESULTS

There was excellent agreement (K >0.75, P < 0.001) between MRI and intraoperative findings for invasive placenta, bladder and parametrial involvement. Intraplacental T₂ dark bands, myometrial disruption, uterine bulge, and hypervascularity at the utero-placental interface or parametrium, showed significant association (P < 0.005) with poor clinical outcome for both mother and fetus. The MRI score showed significant predictive ability for each adverse maternal event (area under the curve [AUC]: 0.85-0.97, P < 0.001). The presence of ≥3 MRI signs was the cutoff point for a complicated delivery (OR: 19.08, 95% confidence interval [CI]: 6.05-60.13) and ≥6 MRI signs was the cutoff point for massive bleeding (OR: 90.93, 95% CI: 11.3-729.23), hysterectomy (OR: 72.5, 95% CI: 17.9-293.7), or extensive bladder repair (OR: 58.74, 95% CI: 7.35-469.32). The MRI score was not significant for predicting adverse neonatal events including preterm delivery (P = 0.558), low birthweight (P = 0.097), and 5-minute Apgar score (P = 0.078).

DATA CONCLUSION

Preoperative identification of specific MRI features may predict peripartum course in high-risk patients for PAS.

Anesthetic management of cesarean section in cases of placenta accreta, with versus without abdominal aortic balloon occlusion: study protocol for a randomized controlled trial

BACKGROUND

Placenta accreta (PA), a severe complication during delivery, is closely linked with massive hemorrhage which could endanger the lives of both mother and baby. Moreover, the incidence of PA has increased dramatically with the increasing rate of cesarean deliveries in the past few decades. Therefore, studies evaluating the effects of different perioperative managements based on different modalities in the treatment of PA are necessary. Among the numerous treatment measures, prophylactic abdominal aortic balloon occlusion (AABO) in combination with cesarean section for PA seems to be more advantageous than others. However, up to now, all studies on AABO were almost retrospective. Current evidence is insufficient to recommend for or against routinely using the AABO technology for control intraoperative hemorrhage in patients with PA. Thus, we hope to carry out a prospective, randomized controlled trial (RCT) study to confirm the effectiveness of the AABO technology in patients with PA.

METHODS/DESIGN

This trial is an investigator-initiated, prospective RCT that will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. A total of 170 parturients with PA undergoing cesarean section will be randomized to receive either AABO in combination with cesarean section or the traditional hysterectomy following cesarean section. The primary outcome is estimated blood loss. The most important secondary outcome is the occurrence of cesarean hysterectomy during delivery; others include blood transfusion volume, operating time, neonate's Apgar scores (collected at 1, 5 and 10 min), length of stay in intensive care unit, total hospital stay, and balloon occlusion-relative data.

DISCUSSION

This prospective trial will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. It may provide strong evidence about the benefits and risks of AABO in combination with cesarean section for parturients with PA.

The effectiveness of double incision technique in uterus preserving surgery for placenta percreta

BACKGROUND

Placenta percreta is a life-threatening condition that places patients at risk of massive bleeding. It necessitates very complicated surgery and can result in mortality. Caesarean hysterectomy is the accepted procedure worldwide; however, recent studies discussing conservative treatment with segmental resections have been published. Foetal extraction and segmental resection can be performed through the same incision (single uterine incision) or through two different incisions (double uterine incision). In this study, we aimed to evaluate the effectiveness and results of the double incision technique.

METHODS

Twenty-two patients with a diagnosis of placenta percreta who underwent conservative surgery were included. Segmental resection was performed via single incision in ten patients and double incision in twelve patients.

RESULTS

There was no difference between the patients who underwent segmental resection via single and double incision in terms of age, gravida, number of previous caesarean deliveries, gestational age at delivery, or rate of elective surgeries. The operation time, transfusion requirement, intensive care unit admission, total hospitalization and success of conservative surgery were comparable between the groups.

CONCLUSIONS

Based on the outcomes of our study, double uterine incision allows for the safe extraction of the foetus during uterus-preserving surgery in patients with placenta percreta without worsening the results compared to single uterine incision.

Macroscopic Hematuria due to Placenta Percreta: Report of Two Cases and Short Review

Herein we present two cases of pregnant women with placenta percreta and severe hematuria during the 24th and 35th weeks of pregnancy, respectively. A timely sonographic diagnosis was feasible in the first case and cesarean section was performed during the 29th week. During the operation, the placenta was invading the bladder wall and concomitant hysterectomy with cystotomy and bladder wall reconstruction was performed. The second case presented in our emergency department with vaginal bleeding during the 35th weeks of pregnancy. She underwent an emergency cesarean section with uterine preservation, cystotomy, and bladder reconstruction.

Placenta percreta managed by transverse uterine fundal incision with retrograde cesarean hysterectomy: a novel surgical approach

Key Clinical Message

Placenta percreta (with bladder invasion) is a rare obstetric condition with the risk of massive intraoperative hemorrhage. In these cases, the combination of a transverse uterine fundal incision and retrograde cesarean hysterectomy could be useful to minimize maternal hemorrhage and avoid severe bladder injury.

Peri-operative management of hysterostomy in a parturient with complete heart block, placenta accreta and intrauterine death

BACKGROUND

Complete heart block in pregnancy has serious implications particularly during the period of delivery. This is more so if the delivery is an operative one as the presence of heart block may produce haemodynamic instability in the intra operative period. We report a unique case of a pregnant mother with complete heart block undergoing hysterostomy, complicated by placenta accreta and intrauterine death.

CASE PRESENTATION

A 37 year old Malaysian Chinese parturient was admitted at 25 weeks gestation following a scan which suggested intrauterine death and placenta accreta. She was diagnosed to have congenital complete heart block after her first delivery eight years previously but a pacemaker was never inserted. These medical conditions make her extremely likely to experience massive bleeding and haemodynamic instability. Among the measures taken to optimise her pre-operatively were the insertion of a temporary intravenous pacemaker and embolization of the uterine arteries to minimize peri-operative blood loss. She successfully underwent surgery under general anesthesia, which was relatively uneventful and was discharged well on the fourth post-operative day.

CONCLUSION

Congenital heart block in pregnancies in the presence of potential massive bleeding is best managed by a team, with meticulous pre-operative optimization. Suggested strategies would include insertion of a temporary pacemaker and embolization of the uterine arteries to reduce the risk of the patient getting into life threatening situations.

Placenta Percreta With Invasion into the Urinary Bladder

Placenta percreta is a rare condition, which can lead to significant morbidity and potentially mortality. We present a case of a 38-year-old woman who presented at 24 weeks gestation with vaginal bleeding and was found to have complete placenta previa with placenta percreta invading the urinary bladder. Her hospital course was complicated by bilateral pulmonary emboli. She underwent an exploratory laparotomy, repeat Caesarean section, and total abdominal hysterectomy. Because of placental invasion into the bladder, the procedure was complicated by bladder and ureteral injuries for which urology carried out repair. Postoperatively, the patient had a persistent bladder leak until postoperative day #39.

Approaches to reduce urinary tract injury during management of placenta accreta, increta, and percreta: a systematic review

OBJECTIVE

A systematic review of the literature was conducted to answer the following question: are there enhancements to standard peripartum hysterectomy technique that minimize unintentional urinary tract (UT) injury in pregnancies complicated by invasive placental attachment (INPLAT)?

METHODS

A PubMed search of English language articles on INPLAT published by June 2010 was conducted. Data regarding the following parameters was required for inclusion in the quantitative analysis of the review's objective: (1) type of INPLAT, (2) details pertaining to medical and surgical management of INPLAT, and (3) complications, if any, associated with management. An attempt was made to identify approaches that may lower the risk of unintentional UT injury.

RESULTS

Most cases (285 of 292) were managed by hysterectomy. There were 83 (29%) cases of unintentional UT injury. Antenatal diagnosis of INPLAT lowered the rate of UT injury (39% vs. 63%; P = 0.04). Information regarding surgical technique or medical management was available for 90 cases; 14 of these underwent a standard hysterectomy technique. Methotrexate treatment and 11 modifications of the surgical technique were associated with 16% unintentional UT injury rate as opposed to 57% for standard hysterectomy (P = 0.002). The use of ureteral stents reduced risk of urologic injury (P = 0.01). Multiple logistic regression analysis identified antenatal diagnosis as the significant predictor of an intact UT.

CONCLUSIONS

Antenatal diagnosis of INPLAT is paramount to minimize UT injury. Utilization of management modifications identified in this review may reduce urologic injury due to INPLAT.

Urologic emergencies in pregnancy

The management of urological emergencies during pregnancy presents unique clinical challenges for the treating physician. Clinical signs and symptoms are often subtle while diagnostic and therapeutic options are limited in treating patients to avoid fetal morbidity. A high index of suspicion with early diagnosis and treatment are essential for the management of genitourologic emergencies in pregnant women. It is essential for patients to be managed on an individual basis using a multidisciplinary approach.

Opening the bladder for cesarean hysterectomy for placenta previa percreta with bladder invasion

Cesarean hysterectomy for placenta previa percreta with bladder invasion often induces not only massive hemorrhage but also severe bladder/ureter injuries. A 37-year-old woman with previous cesarean delivery suffered placenta previa percreta with bladder invasion. At the 34th week, we performed cesarean hysterectomy. Without separating the bladder from the uterus/cervix, we incised the bladder lateral wall using an automatic stapling/cutting device, leaving the bladder posterior wall adhering to the uterus and resecting it with the uterus. The bladder was easily repaired without urological sequelae. We suggest a new, simple and safe technique for cesarean hysterectomy for this disease.

Difficulty of the surgical management of a case with placenta percreta invading towards parametrium

A 37-year-old woman was admitted due to vaginal bleeding at 25 weeks of gestation to our gynecology unit. Placenta percreta, which stems from posterior wall of the uterus, forming a mass in Douglas cavity and invading towards right parametrium was clinically diagnosed by exploration. Bilateral internal iliac artery ligation and supracervical hysterectomy could not prevent bleeding. A right radical parametrectomy was necessary to remove invaded parametrium and to control bleeding. The placenta percreta invading parametrium may need an extended hysterectomy procedure. Excess bleeding may be prevented by leaving the placenta in situ during surgery if the placenta percreta is diagnosed before termination of pregnancy, A classical incision may help leaving placenta is situ during operation.

Placenta percreta causing rupture of an unscarred uterus at the end of the first trimester of pregnancy: Case report

Reports on placenta percreta in early pregnancy leading to a spontaneous rupture of the uterus are rare. We report a case of this potentially life-threatening complication in the 14th week of pregnancy in an otherwise healthy woman who underwent a manual extraction of the placenta during a previous delivery but who had no history of severe pathology that could have potentially resulted in uterine damage. The occurrence of severe abdominal pain and the presence of a large quantity of free fluid in the abdomen necessitated an emergency laparotomy, revealing a haemoperitoneum due to rupture of the uterus, which was followed by a hysterectomy. This case demonstrates that in patients with a history of placenta accreta and subsequent manual extraction of the placenta, a close investigation of the uterine wall and placentation should be performed in the first trimester in order to anticipate a placenta percreta.

Placenta percreta invading the urinary bladder

INTRODUCTION

Placenta percreta is a rare obstetric complication causing life-threatening hemorrhage.

CASE REPORT

The case of a woman with a placenta percreta invading the urinary bladder treated by cesarean hysterectomy and partial bladder resection is presented. Overall estimated blood loss was 11,130 ml, and 59 units of various blood products were transfused.

CONCLUSION

Obstetricians and urologists should be aware of this rare condition.

Anterior placenta percreta: surgical approach, hemostasis and uterine repair

BACKGROUND

To describe an accurate approach, hemostatic procedures and uterine repair in patients with anterior placenta percreta.

METHODS

A total of 68 patients with anterior placenta percreta were included. A large retrovesical and parametrial dissection was performed in all cases. Hemostasis was achieved with selective vascular ligature or with surgical myometrial compression. The anterior wall defect was repaired using a myometrial suture, fibrin glue and polyglycolic mesh. Finally, a nonadherent cellulose layer was applied over this reconstruction. Hysteroscopy and T2 magnetic resonance imaging (MRI) were performed as a reconstruction control at 90 days after discharge.

RESULTS

Elective surgery was performed in 49 patients and emergency surgery in 19. In 59 midline incisions were performed and in nine lower transverse incisions. Forty-nine patients underwent fundal hysterotomy and 19 transplacental segmental uterine approaches. The uteri of 50 patients with anterior placenta percreta were repaired. Of the 18 hysterectomies performed in this series, 16 were indicated due to massive destruction and two were secondary to coagulopathies. The following surgical complications developed: pelvic hemorrhage (one), coagulopathies (two), uterine infection (three), low ureteral ligations (two), iatrogenic foreign bodies (two) and collection (three). Uterine conservation was highly significant between the upper and lower invasion areas. Ten pregnancies were reported after the repair, resulting in uncomplicated cesarean delivery.

CONCLUSION

This approach has allowed an adequate uterine repair in patients with anterior placenta percreta. Based on these results it is valid to assume that a functional and anatomic uterine repair has been successfully performed.
