Modified one-step conservative uterine surgery (MOSCUS) versus cesarean hysterectomy in the management of placenta accreta spectrum: A single-center retrospective analysis based on 619 Vietnamese pregnant women

OBJECTIVES

To compare maternal outcome measures in surgical management of placenta accreta spectrum (PAS)-the modified one-step conservative uterine surgery (MOSCUS), a new approach at Tu Du Hospital in Vietnam, versus cesarean hysterectomy, and to identify factors that appear to contribute to the successful outcome of the MOSCUS.

METHODS

This retrospective study was conducted at Tu Du Hospital in southern Vietnam between January 2019 and December 2020. The study enrolled all pregnant women at more than 28 weeks of pregnancy with a diagnosis of PAS who underwent either a cesarean hysterectomy or a uterus-preserving approach using the MOSCUS method.

RESULTS

The prevalence of PAS at our single tertiary referral hospital was 0.4% (619 PAS cases/132 518 births) in 2 years. Among 296 patients, the surgical time duration, estimated blood loss, and red blood cell transfusion in the MOSCUS group (n = 217) were all significantly less than in the cesarean hysterectomy group (n = 79) (152.72 ± 42.23 vs 185.13 ± 58.22 min, 1000 vs 1500 mL, and 500 vs 710 mL, respectively). Intraoperatively, the rate of visceral injuries in the hysterectomy group was higher than that in the MOSCUS group (P < 0.001). However, the rate of postoperative infection was higher in the MOSCUS group than in the cesarean hysterectomy group (P = 0.012). Of a total of 217 cases managed using the MOSCUS management, 24 required a secondary hysterectomy; the success rate was 88.9% (95% confidence interval [CI] 84.3%-93.1%). Some of the primary factors associated with the success of MOSCUS included maternal age less than 35 years, planned surgery, severity of PAS, and estimated blood loss during surgery (odds ratio [OR] 5.16, 95% CI 1.96-13.59; OR 3.05, 95% CI 1.08-8.62; OR 3.62, 95% CI 1.19-10.98; and OR 49.66, 95% CI 11.16-221.02, respectively; P < 0.05).

CONCLUSION

MOSCUS is an acceptable alternative to cesarean hysterectomy in many patients diagnosed with PAS. This new surgical management of PAS resulted in the preservation of the uterus, and a favorable outcome in nearly 9 out of 10 pregnant women. We believe that MOSCUS can be safely offered for the management of PAS in referral hospital settings.

Conservative management versus cesarean hysterectomy in patients with placenta increta or percreta

OBJECTIVE

To compare conservative management and cesarean hysterectomy in patients with placenta increta or percreta.

MATERIALS AND METHODS

In this multicenter retrospective study, we recorded data on 2219 patients with placenta increta or percreta from 20 tertiary care centers in China from 1 January 2011 to 31 December 2015. Propensity score analysis was used to control for baseline characteristics. We divided patients into conservative management (C) and hysterectomy (H) groups. The primary outcome was operative/postoperative maternal morbidity; secondary outcomes were maternal-neonatal outcomes.

RESULTS

In total, 17.9% (398/2219) of patients had placenta increta and percreta; 82.1% (1821/2219) of the patients were in group C. After propensity score matching, 140 pairs of patients from the two groups underwent one-to-one matching. Group C showed less average blood loss within 24 h of surgery (1518 ± 1275 vs. 4309 ± 2550 ml in group H, p<.001). There were more patients with blood loss >1000 ml in group H than in group C (93.6% [131/140] vs. 61.4% [86/140], p<.001). More patients received blood transfusions in group H than in group C (p=.014). There was no significant difference between the groups in terms of bladder injury, postoperative anemia, fever, and disseminated intravascular coagulation. Neonatal outcomes in the two groups were similar.

CONCLUSION

Either conservative management or hysterectomy should be considered after thorough evaluation and detailed discussion of risks and benefits. A balance between bleeding control and fertility can be achieved.

Cesarean delivery with and without uterine artery embolization for the management of placenta accreta spectrum disorder-A comparative study

INTRODUCTION

The aim of this study is to compare immediate and long-term obstetrical outcomes of patients who underwent cesarean delivery with and without uterine artery embolization (UAE) for the management of placenta accreta spectrum disorder.

MATERIAL AND METHODS

A retrospective case control study including all pregnant women admitted to a single tertiary medical center between December 2001 and May 2018 with a diagnosis of placenta accreta spectrum disorder, who underwent cesarean delivery with and without UAE. Groups were compared for maternal characteristics, operative management, postoperative complication rate and long-term outcomes. Follow up on future obstetrical outcomes was conducted via telephone questionnaire. Non-parametric statistics were used.

RESULTS

During the study period, 272 women met the inclusion criteria: 64 (23.53%) and 208 (76.47%) underwent preservative cesarean section with and without UAE, respectively. UAE procedure was associated with a longer operative time (82.5 [68-110] vs 50.5 [39-77] minutes; P = .001), and higher blood loss (2000 (1500-3000) vs 1000 (600-2000) mL; P = .001). Hysterectomy rate was comparable between the groups (9 [14%] vs 35 [16.82%]; P = .88); however, multivariate logistic regression analysis found UAE to be an independent factor associated with lower hysterectomy rate (P = .02). Postoperative complications were more frequent in the UAE group. Follow up was achieved in 29 (59.18%) and 72 (51.79%) of the women with and without UAE, respectively (P = .36). No differences were found in rate of abortions, pregnancy and deliveries between the groups.

CONCLUSIONS

Cesarean delivery using UAE in placenta accreta spectrum disorder is associated with a higher rate of operative and postoperative complications. Nevertheless, in cases of severe adherence of the placenta, embolization reduces the need for hysterectomy, allowing future fertility.

[Placenta accreta spectrum disorder: Management and morbidity in a French type-3 maternity]

OBJECTIVES

Placenta accreta spectrum disorder (PASD) is a rare obstetrical pathology, however its incidence is increasing. Morbidity associated with PASD is still high. Even if hysterectomy is considered to be the reference standard treatment, the conservative treatment by leaving the placenta in situ is now an approved option. The objective was to describe management and morbidity of patients with PASD, during the decade, in our French high-level maternity.

METHODS

It was a retrospective study of management and morbidity of PASD in our department between 2007 and 2017.

RESULTS

Forty-six PASD cases were admitted in our center. Thirty-three (71.7%) had a prenatal suspicion of PASD. Conservative treatment was considered for 22 patients (47.8%). It was successful in 12 cases (54.5%). Thirty-four (73.9%) had a primary hysterectomy, eight (17.3%) had a delayed hysterectomy, four (8.6%) had a uterine conservation. Primary Morbidity included 28 blood transfusions, 12 bladder injuries, 1 ureteral injury and 13 transfers to intensive care unit. Secondary morbidity after conservative treatment included two Hemorrhages (16.6%), five endometritis (41.6%) and three disseminated intravacular coagulations (25%).

CONCLUSIONS

Morbidity associated with this pathology is severe. Conservative treatment became an option for PASD. Thanks to a better antenatal diagnosis, it can be proposed to more women. Morbidity seems the same as other centers. Our rate of primary and secondary hysterectomy is higher than other centers. Conservative treatment seems an effective option for women who desire to preserve their fertility to avoid peripartum hysterectomy and its related morbidity and consequences on fertility.

The parameters affecting the success of uterus-sparing surgery in cases of placenta adhesion spectrum disorder

OBJECTIVE

This study aimed to evaluate the parameters affecting the treatment success of conservative surgery in cases with placental invasion anomaly.

METHODS

Archive files and digital image records of 67 patients with placental invasion anomaly were studied. The patients were divided into two groups, a conservative surgery group and a cesarean hysterectomy group. Demographic data, cervical length, placental localization, placental surface area adhering to previous cesarean section line, preoperative and postoperative hematocrit values, transfused blood products, and surgical complications were compared between the two groups.

RESULTS

In the conservative surgery group, the cervical length was longer (p < .001) and the surface area of the placenta in the previous cesarean scar line was smaller (p < .001). For cervical length, the sensitivity and specificity values were 97 and 81%, respectively, when the cut-off value was 35.5 mm. When the cut-off value for the placental surface area in the previous cesarean scar line was 85.5 cm², the sensitivity and specificity values were 68 and 72%, respectively. In the caesarean hysterectomy group, the preoperative and postoperative hematocrit values were lower (p < .001, p = .003, respectively), and the amount of transfused erythrocyte suspension and fresh frozen plasma were higher (p < .001, p = .001, respectively).

CONCLUSION

In this study, it was concluded that the presence of the nondestructive intact cervical tissue, in the cases with placental invasion anomaly and/or the small size of the placental surface area adhering to the previous cesarean scar line, increase the feasibility of conservative surgery.

An analysis of maternal-fetal prognosis in patients with placenta accreta

Objective: To retrospectively analyze the clinical data and outcome of patients with placenta accreta.Methods: The clinical parameters of a total of 66 patients with placenta accreta who had received a C-section were analyzed and the patients were grouped and stratified for the analysis.Results: Of the patients with or without a history of 0-2 C-sections, 15 patients received hysterectomy, adherent placenta was observed in two patients, placenta increta was observed in five patients, and placenta percreta was observed in eight patients, as confirmed by the postoperative pathological results. Blood loss was higher in the patients with a previous history of uterine scarring and an ultrasound diagnosis than in those without a history of uterine scarring and those in the control group and blood loss increased with the depth of placenta implantation. The incidence of hysterectomy was higher in the patients with 4-9 pregnancies or a postoperative diagnosis of placenta percreta than in the patients in the control group. The rate of hysterectomy was lower in the patients who received comprehensive management.Conclusion: More blood loss was reported in the patients with a history of uterine scarring and C-sections should be limited in these patients. Comprehensive management was associated with a lower rate of hysterectomy.

Ovarian reserve after uterine artery embolization in women with morbidly adherent placenta: A cohort study

Objective

To evaluate ovarian reserve in women after preservative cesarean delivery using uterine artery embolization due to morbidly adherent placenta.

Study design

A historical cohort study including all women admitted to a single tertiary care center, with morbidly adherent placenta that had preservative cesarean delivery with bilateral uterine artery embolization. Inclusion criteria included gestational age >24 weeks, singleton pregnancy and placenta increta / percreta. Exclusion criteria included maternal age > 43 years old and cesarean hysterectomy. Control group included women attending the infertility clinic due to male factor or single women conceiving via sperm donation, matched by age. Blood samples were collected on day 2–5 of menstruations for hormonal profile and Anti Mullarian Hormone (AMH) levels. Primary outcome was ovarian reserve evaluated by the levels of AMH.

Results

59 women underwent preservative cesarean delivery using uterine artery embolization during the study period. 21 women met inclusion criteria (33.9%) and were matched controls (n = 40). Circulating levels of E2 and FSH did not differ significantly between the two groups (p = 0.665, p = 0.396, respectively). AMH was lower in the study group (median 0.8 IQR 0.44–1.80) compared to the controls (median 2.08 IQR 1.68–3.71) (p = 0.001). This finding was consistent in linear multivariate regression analysis where the group of cesarean delivery using bilateral artery embolization due to placenta accrete was significantly predictive for the levels of AMH (B = -1.308, p = 0.012).

Conclusion

Women post preservative cesarean delivery using uterine artery embolization due to placenta accrete have lower ovarian reserve compare to controls matched by age.

Safety and efficacy of preoperative abdominal Aortic balloon occlusion in placenta increta and/or percreta

BACKGROUND

With the increase of cesarean deliveries globally, the incidence of placenta adhesive disorder has been on the rise greatly which is associated closely with maternal and infant morbidity and mortality. We sought to investigate the safety and efficacy of preoperative transfemoral balloon occlusion of abdominal aorta in cesarean section of women with placenta increta or percreta.

METHODS

We conducted a retrospective study of 31 patients with placenta increta or percreta diagnosed by ultrasound and/or magnetic resonance imaging. The observation group included 19 patients who received transfemoral abdominal aorta balloon occlusion for preoperative prophylaxis, while the other 12 patients in the control group did not receive any preoperative interventional managements. Clinical outcomes were compared between the two groups.

RESULTS

Patients in observation group had significantly less estimated blood loss during surgery than those in control group (1.2 L versus 3.15 L, P = 0.006). The average transfusion volume of the observation group was significantly lower than the control group (0.8 L versus 1.95 L, P = 0.017). Seventy-nine percent (15 of 19) patients in the observation group and 50% (6 of 12) in the control group had their uterus successfully retained (P = 0.093). No peripheral tissues including bladder, ureter, and bowel were injured in all patients. Neonatal weight and Apgar scores of 1 min and 5 min had no statistical difference (P = 0.513 and P = 1, respectively) between the two groups. The mean radiation exposure time of fetus in the observation group was 22.68 ± 8.07 s and mean radiation exposure dose was 4.20 ± 1.49 mGy. Both operation time and postoperative hospital stay had no statistical difference between the two groups (2 versus 2.75 h, P = 0.063; 7.0 versus 6.5 d, P = 0.846). No patients had long-term complications after 6-8 wk follow-up.

CONCLUSIONS

Application of preoperative transfemoral abdominal aorta balloon occlusion during cesarean section is a safe and effective strategy for patients with placenta increta and/or percreta. It could reduce intraoperative blood loss and enhance the possibility of uterus preservation and ensure the safety of life from severe complications.
