Management of uterine rupture: a case report and review of the literature

Uterine rupture following prostaglandins use in second trimester medical abortion: Fact or fiction? A systematic review

BACKGROUND

Prostaglandins (PGs) have emerged as key drugs in second trimester medical abortion (STMA) and are currently a cornerstone in obstetric practice. Nevertheless, the application of PGs, integral to labor and abortion procedures, is not risk-free, and has been associated with several complications, particularly maternal fever and uterine rupture (UR).

OBJECTIVES

The main outcome of the present systematic review was to assess the safety of PGs use in STMA, particularly in scarred uterus (SC).

SEARCH STRATEGY

The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. We performed a comprehensive systematic review by searching multiple databases, including MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database, and the research registers of Web of Science during the years 1990-2022.

SELECTION CRITERIA

Only articles regarding cases of UR occurred after the use of PGs for STMA were included in the article. We excluded papers regarding UR during first trimester abortion induction of labor or pregnancy or unrelated to PGs use for STMA. Risk of bias was assessed employing a modified version of the "Newcastle-Ottawa Scale" (NOS).

DATA COLLECTION AND ANALYSIS

A total of 178 studies were initially identified as potentially meeting the criteria for inclusion in the review. After full text evaluation, 110 other articles were excluded and 67 studies that suited the inclusion criteria were included. A total of 19 of the included studies were judged to have a high risk of bias. Given the heterogeneous nature of the findings, we opted for a narrative synthesis of the results.

MAIN RESULTS AND CONCLUSIONS

PGs appear to be an effective pharmacologic tool for STMA; however, their use is not entirely risk-free. STMA requires well-equipped obstetric centers with skilled clinicians and surgeons prepared for emergencies. Ultrasonographic scans should be routinely performed during STMA management, since a UR can also be silent during the induction of labor. Intrapartum transabdominal, transperineal, and transvaginal ultrasound may have the diagnostic potential to early recognize this obstetric emergency, to facilitate rapid medical and surgical treatment, improving the outcome.

Risks and Outcomes of Uterine Rupture in Women With and Without a Trial of Labour

OBJECTIVES

The study aimed to evaluate the maternal and neonatal outcomes in patients who experienced uterine rupture, comparing those who underwent a trial of labour to those who did not.

METHODS

A population-based retrospective study was conducted in a tertiary university medical centre from 2008 to 2019. The cohort consisted of all women who were diagnosed with uterine rupture during cesarean delivery (CD) or laparotomy. Patients with 1 previous CD who underwent a trial of labour (TOLAC group) were compared against patients who had a history of CD in whom no trial of labour occurred, and/or against patients who had no prior CD in whom a ruptured uterus was diagnosed during or following delivery (no-TOLAC group). Patients with uterine scar dehiscence were excluded.

RESULTS

Of 103 542 women who gave birth during the study period, 10 325 had a previous CD. Uterine rupture occurred in 95 cases: 55 among patients who had undergone TOLAC (0.98%) and 40 (0.85%) without trial of labour. Compared with the TOLAC group, the subgroup of women with a single prior CD who did not attempt TOLAC (n = 16) had a higher rate of neonatal intensive care unit admission (56.3% vs. 21.7%, OR 4.15; 95% CI 1.3-13.3, P = 0.01) and adverse composite maternal outcomes (blood transfusion, urinary bladder injury, and/or intensive care unit admission) (75% vs. 30.9%, OR 6.7; 95% CI 1.8-23.8, P < 0.01). There was no neonatal or maternal death in any group.

CONCLUSIONS

Despite the higher incidence of uterine rupture in women undergoing TOLAC, outcomes are less favourable when rupture occurs outside the trial of labour and if the uterus is unscarred.

Trend, prevalence, and associated factors of uterine rupture at Nekemte Specialized Hospital, Oromia Regional State, Western Ethiopia

Maternal morbidity and mortality have long been among the world's most challenging health issues. Uterine rupture is one of the peripartum complications that kills almost one in every thirteen mothers. However, there is limited evidence on uterine rupture trends, proportions, and determinants. Thus, this study assessed the trend, prevalence, and associated factors of uterine rupture at Nekemte Specialized Hospital, Oromia Regional State, Western Ethiopia. An institution-based cross-sectional study was conducted among 2661 clients selected using a systematic random selection technique among the data collected for the project between January 2014 and December 2022 at Nekemte Specialized Hospital. Data were collected through an interview-administered questionnaire and card review from March 2023 to August 2023. The collected data were checked, coded, and entered into Epi info version 7.2 and then exported to SPSS Version 27 for analysis. Logistic regression models were fitted to identify the factors of uterine rupture. Adjusted odds ratio with 95% Confidence Interval was estimated to measure the strength of the association, and statistical significance was declared at a p-value less than 0.05. The trend of uterine rupture declined from 1.54% in 2014 to 0.93% in 2022. The overall prevalence was 3.53% (95%CI: 2.7%, 4.3%). Low household income (Adjusted OR = 3.75, 95%CI: 1.97, 7.13), grandmultiparity (Adjusted OR = 7.78, 95%CI: 4.70, 12.88), having a history of obstetrics complications such as prolonged labor (Adjusted OR = 3.78, 95%CI:2.11, 6.75), a history of cesarean section (Adjusted OR = 2.49, 95%CI:1.42, 4.35), and history of uterine repair (Adjusted OR = 18.01, 95%CI: 6.81, 47.64) were significantly associated with uterine rupture. This finding showed that the trend is declining, and the proportion of uterine rupture is still higher. A more vigilant approach to increase access to lower-income mothers, prevent prolonged and obstructed labor, and maintain antenatal care with complete packages and a referral system are issues to be addressed to minimize the chance of uterine rupture among women.

Spontaneous Rupture of a Non-scarring Gravid Uterus: A Late and Haphazard Diagnosis in the Postpartum Period

This paper reports the case of a spontaneous rupture of a non-scarring gravid uterus seen four days after vaginal delivery and provides an update on this rare pathology, which can be functionally and vitally life-threatening. Uterine rupture of a healthy gravid uterus can occur as a result of structural abnormalities of the uterine tissue framework or uterine parietal fragility due to pathological phenomena such as septic states. On admission, the clinical picture is generally that of an acute abdomen with a hypogastric origin, with or without hemodynamic instability and an altered general condition, depending on the presence of an underlying advanced uterine infection. Medical imaging, mainly ultrasound and CT scan with iodine contrast, enables visualization of the uterine breach and a precise assessment of the damage. Surgery is the treatment of choice for repairing the breach and ensuring hemostasis. This case study sheds light on this pathology, familiarizing us with its clinical and radiological picture, as well as its post-treatment prognosis.

Strengthening caesarean birth: Sub-Saharan Africa health system evaluation: Scoping review

BACKGROUND

 Promoting safe caesarean birth (CB) is a challenge in sub-Saharan Africa (SSA) where maternal and neonatal mortality rates are high due to inadequate maternal health services. Although the CB rate in SSA is lower than the World Health Organization (WHO) recommendation, it is often associated with high maternal and neonatal mortality.

AIM

 The aim of this scoping review was to report on the extent to which SSA health systems deliver safe CB.

METHODS

 A systematic search across various databases identified 53 relevant studies, comprising 30 quantitative, 10 qualitative and 16 mixed methods studies.

RESULTS

 These studies focused on clinical protocols, training, availability, accreditation, staff credentialing, hospital supervision, support infrastructure, risk factors, surgical interventions and complications related to maternal mortality and stillbirth. CB rates in SSA varied significantly, ranging from less than 1% to a high rate of 29.7%. Both very low as well as high rates contributed to significant maternal and neonatal morbidity. Factors influencing maternal and perinatal mortality include poor referral systems, inadequate healthcare facilities, poor quality of CBs, inequalities in access to maternity care and affordable CB intervention.

CONCLUSION

 The inadequate distribution of healthcare facilities, and limited access to emergency obstetric care impacted the quality of CBs. Early access to quality maternity services with skilled providers is recommended to improve CB safety.Contributions: This scoping review contributes to the body of knowledge motivating for the prioritization of maternal service across SSA.

Labisia pumila as a Culprit of Primary Uterine Rupture Alongside Abruptio Placentae: A Case Report

Purpose

Uterine rupture is a rare obstetrical and surgical emergency but is often associated with a catastrophic obstetric complication. Traditionally, unscarred uteri without risk factors are considered immune to rupture and information about its risk factors is only few due to its rarity. Complementary and alternative medicine is commonly used in pregnant woman in southeast Asian countries such as Indonesia, however information regarding its toxicity due to irrational use is few. This case report presents a G2P1A0 35-year-old woman with acute abdomen with spontaneous unscarred uterine rupture >15 cm after continuously consuming herbal water made of Kacip Fatimah leaves in boiling water.

Case Description

A 35-year-old pregnant woman was referred to hospital due to abdominal discomfort 3 hours before admission due to suspicion of intrauterine fetal death. She drank the extracted herbal water to help her when the labor comes, which was made from boiled water with rumput Fatimah from her neighbor's house. Then, she was diagnosed with G2P1A0 parturient aterm latent phase; acute abdomen due to suspicion of placentae abruption dd/ ruptur uteri; and Intrauterine Fetal Death. Exploratory laparotomy was decided due to acute abdominal pain, and during the procedure the operator decided to do subtotal hysterectomy on the patient. The operator found her uterine was already ruptured, approximately 15-18 cm and the placentae was located outside of the uterus.

Conclusion

This case suggest that rational usage of herbal medicine must be implemented to avoid unwanted complication.

Spontaneous Rupture of the Unscarred Uterus: A Review of the Literature

Importance

Uterine rupture is defined as a nonsurgical disruption of all layers of the uterus. Most ruptures occur in the presence of a scar, usually secondary to a previous cesarean delivery. Rupture of an unscarred uterus is rare and is associated with severe maternal and neonatal outcomes.

Objective

To outline the literature on potential predisposing factors, clinical findings, and maternal and fetal outcomes of a rupture of an unscarred uterus.

Evidence Acquisition

PubMed was searched for the phrases "uterine rupture," "unscarred," and "spontaneous." Individual case reports, retrospective case series, and review articles in English between 1983 and 2020 were included.

Results

We found 84 case reports in 79 articles. The mean maternal age was 29.3 (SD, 5.7) years; 38 women (45.2%) were nulliparous. Uterine rupture occurred in 37% of the women at term; in 9.9%, the gestational age was ≤12 weeks. The most common clinical presentations were abdominal pain (77.4%), signs of hypovolemic shock (36.9%), fetal distress (31%), and vaginal bleeding (22.6%). The most common risk factors were the use of uterotonic drugs for induction or augmentation of labor and a prior curettage procedure. The most frequently ruptured site was the body of the uterus. Hysterectomy managed 36.9% of the ruptures. Four women died (4.8%). Perinatal mortality was 50.6%. Perinatal death was higher in developing than developed countries.

Conclusions and relevance

Although rare, spontaneous rupture of the unscarred uterus has serious consequences to the mother and the fetus and should be included in the differential diagnosis of acute abdomen in pregnancy.

Spontaneous Rupture of Unscarred Uterus in a Term Primagravida with Lethal Skeletal Dysplasia Fetus (Thanatophoric dysplasia). A Case Report and Review of the Literature

Background and Importance

 Spontaneous uterine rupture, especially in an unscarred uterus, is a rare pregnancy complication that can cause severe morbidity and mortality in both the mother and the fetus. The vast majority of uterine ruptures occur in the presence of a previous uterine scar, most commonly from a previous cesarean delivery. To our knowledge, here we reported the first case of spontaneous rupture of unscarred uterus in a term primigravida secondary to lethal skeletal dysplasia fetus (Type 1 Thanatophoric dysplasia) faced by a practicing clinician in an underdeveloped country (Somalia) with a successful outcome.

Case Presentation

 The patient was 24 yrs. Old Primagravida, at 40 weeks gestation by LMP, presented with abdominal pain and active vaginal bleeding; she did not receive antenatal care during pregnancy; after initial abdominal ultrasonography and vaginal examination, laparotomy was performed due to high suspicion of uterine rupture. After dead fresh fetal extraction, the uterine defect was repaired successfully, and the patient was discharged home in good condition after several days.

Conclusion

 Through this case, we would like to highlight the urgent need to focus on and recognize the importance of receiving antenatal care in the community so that the burden of thousands of lives lost each year can be reduced.

Parturient with Acute Abdomen

Management of a parturient with an acute abdomen presents unique challenges. We aim to review the common obstetric and nonobstetric causes for acute abdomen in pregnancy, approach to diagnosis, the role of imaging, and management including the scope and timing of operative intervention.

Uterine Rupture Following Non-Operative Vaginal Delivery: A Close Save of Delayed Presentation With Hemoperitoneum to a Rural Tertiary Care Hospital

Hemoperitoneum as a result of uterine rupture in a previously unscarred uterus is a rare entity to encounter and a potentially life-threatening condition. Ruptures can occur in a scarred uterus either spontaneously, due to operative manipulations, or with the use of uterotonic medications. In an unscarred uterus, spontaneous ruptures are known with high parity, use of oxytocin, and prolonged, neglected labor. Ruptures can be silent with no symptoms resulting in a delay in diagnosis and a near-miss situation. Here, we report the case of a 25-year-old young female who was referred to our tertiary care hospital in rural central India six hours after full-term vaginal delivery, which was followed by pain in the lower abdomen. She had no history of cesarean section, laparoscopic procedures, or surgical termination of pregnancy, which would have predisposed her uterus to rupture. She was severely pale on arrival, and a contrast-enhanced computerized tomography scan revealed rupture of the left side of the uterus with hemoperitoneum and a large pelvic hematoma. Because the patient was in hemorrhagic shock, she was immediately taken for laparotomy with simultaneous resuscitative measures and blood transfusion on flow. Extensive uterine rupture, extending through the cervix to the round ligament of the left side involving the left lateral uterine wall, with active bleeding from the site of the defect was confirmed. The hematoma was 10 × 10 cm in size and was evacuated, following which peripartum hysterectomy was done. The left ureter was traced and safeguarded while applying the clamp on Mackenrodt’s ligament. The patient recovered completely following the procedure. She was discharged on day 13 in stable condition. She is currently doing well on follow-up and is a good example of a maternal near miss. In this report, we emphasize that, even in the absence of any obvious risk factor, uterine rupture can occur during labor, and monitoring the vitals of patients in the immediate postpartum period is essential to detect and promptly manage this serious condition for preventing maternal mortality.

Burden of Uterine Rupture and Its Determinant Factors in Ethiopia: A Systematic Review and Meta-analysis

Background. Uterine rupture is a life-threatening obstetrical emergency, which results in serious undesired maternal and perinatal complications in resource-limited countries, mainly in Ethiopia. The prevalence, determinants, and outcomes of uterine rupture described by different studies were highly inconsistent in Ethiopia. Therefore, this systematic review and meta-analysis is aimed at estimating the pooled prevalence, determinants, and adverse outcomes of uterine rupture in Ethiopia. Methods. Studies were searched from international databases (PubMed/MEDLINE, HINARI, Cochrane library, Google Scholar, and web of science) and Ethiopian universities’ digital libraries (Addis Ababa University, University of Gondar, and Harameya University). All observational studies were included. A total of 15 studies that fulfill the inclusion criteria were included in this meta-analysis. Data were extracted by two reviewers and exported to STATA version 11 for analysis. The $I^2$ statistics were used to assess heterogeneity across the studies. Publication bias was examined by using Egger’s test and funnel plot. The pooled prevalence of uterine rupture and its outcomes were estimated by using a random effects model. The associations between determinants and uterine rupture were evaluated by using both random and fixed-effect models. Results. In this meta-analysis, a total of 15 studies with 92,394 study participants were involved. The pooled prevalence of uterine rupture was 2.37% in Ethiopia. Obstructed labor ( $\text{OR}=3.03$ ; $95\%\text{CI}=2.52,3.63$ ), lack of antenatal care follow-up ( $\text{OR}=5.79$ ; $95\%\text{CI}=2.47,13.61$ ), duration of $\text{labor}>24$ hours ( $\text{OR}=3.75$ ; $95\%\text{CI}=2.24,6.29$ ), grand multipara ( $\text{OR}=10.79$ ; $95\%\text{CI}=4.77,24.40$ ), and being rural residency ( $\text{OR}=7.17$ ; $95\%\text{CI}=3.90,13.16$ ) were significantly associated with uterine rupture. Conclusion. The overall prevalence of uterine rupture was high in Ethiopia. Obstructed labor, lack of antenatal care follow-up, duration of $\text{labor}>24$ hours, grand multipara, and rural residency were determinants of uterine rupture. This study implies the need to develop plans and policies to improve antenatal care follow-up and labor and delivery management at each level of the health system.

Spontaneous Uterine Rupture in a Multigravid Pregnant Woman with Unscarred Uterus on Chronic Steroid Use: A Case Report

BACKGROUND

Uterine rupture in pregnancy is associated with severe maternal and fetal complications. Although it is a rare event, uterine rupture has been associated with certain risk factors. Glucocorticoids are known to weaken skeletal muscles; however, there have been no studies on the effects of chronic steroid use on the uterine myometrium.

CASE

We present the case of a 40-year-old multigravid woman who experienced a posterior uterine wall rupture on an unscarred uterus. She was on chronic glucocorticoids for the treatment of psoriatic arthritis. We hypothesize that the catabolic effects of glucocorticoids on skeletal muscles also weakened the uterine myometrium, leading to a higher risk of uterine rupture.

CONCLUSION

Uterine rupture may be associated with chronic use of corticosteroids. Identifying the different risk factors for uterine rupture can lead to more prompt diagnosis and management of uterine rupture, resulting in better maternal and fetal outcomes.

Mifepristone Followed by Misoprostol or Ethacridine Lactate and Oxytocin for Second Trimester Abortion: A Randomized Trial

Objective

To compare two medical methods for second-trimester abortion, mifepristone followed by misoprostol versus mifepristone followed by ethacridine lactate and oxytocin for success rate, induction to abortion time and acceptability.

Materials and Methods

This is a randomized trial conducted from July 2014 to May 2016 and enrolled 120 women undergoing second trimester abortion (13-20 weeks). All patients received 200mg mifepristone orally and were randomized to receive further treatment after 36 hrs. Patients in Group M (n=60) received 400 microgram of misoprostol vaginally every 3 hours (maximum - 5 doses) and Group E (n=60) had extra-amniotic ethacridine lactate instillation followed by oxytocin infusion (max-100miu).

Results

Baseline demographic characteristics were comparable in both the groups. Success rate was 100% in group M and 98.3% in group E (p=0.31). Mean induction to abortion time was significantly shorter in group M than group E (8.2+2.3hours & 10.9+2.6 hours respectively; p=0.001). Majority of women reported side effects, 96.7% women in group M and 75% women in group E (p=0.001). Fall in hemoglobin after procedure was significantly higher in group M (0.70+0.33gram %) than group E (0.52+0.23 gram %) (p=0.001). Perception of intensity of pain was significantly more in group M but patient satisfaction in both groups was similar.

Conclusion

Both methods are comparable for success rate, induction interval was more for ethacridine lactate compared to misoprostol.

Uterine rupture among mothers admitted for obstetrics care and associated factors in referral hospitals of Amhara regional state, institution-based cross-sectional study, Northern Ethiopia, 2013-2017

BACKGROUND

Maternal morbidity and mortality have been one of the most challenging health problems that concern the globe over the years. Uterine rupture is one of the peripartum complications, which cause nearly about one out of thirteen maternal deaths. This study aimed to assess the prevalence and associated factors of uterine rupture among obstetric case in referral hospitals of Amhara Regional State, Northern Ethiopia.

METHODS

Institution based cross sectional study was conducted from Dec 5-2017-Jan 5-2018 on uterine rupture. During the study randomly selected 750 charts were included by using simple random sampling method. Data were checked, coded and entered into Epi info version 7.2 and then exported to SPSS Version 20 for Analysis. Binary Logistic regression was used to identify the predictors of uterine rupture and 95% Confidence Interval of odds ratio at p-value less than 0.05 was taken as a significance level.

RESULT

The overall prevalence of uterine rupture was 16.68% (95% CI: 14%, 19.2%). Distance from health facility >10km (Adjusted Odds Ratio (AOR) = 2.44; 95%CI:1.13,5.28), parity between II and IV (AOR = 7.26;95% (3.06,17.22)) and ≥V (AOR = 12.55;95% CI 3.64,43.20), laboring for >24hours(AO = 3.44; 95% CI:1.49,7.92), with referral paper(AOR = 2.94;95%CI:1.28,6.55) diagnosed with obstructed labor (AOR = 4.88;95%CI: 2.22,10.70), precipitated labor (AOR = 3.59;95%CI:1.10,11.77), destructive delivery (AOR = 5.18;95%: 1.22,20.08), No partograph (AOR = 5.21; 95% CI: 2.72,9.97), CPD(AOR = 4.08;95%CI:1.99,8.33), morbidly adherent placenta (AOR = 9.00;95%:2.46,27.11), gestational diabetic militias (AOR = 5.78; 95%CI:1. 12,20 .00 ), history of myomectomy(AOR = 5.00;95%CI:1.33,18.73), induction and augmentation of labor (AOR = 2.34;95%:1.15,4.72) obstetric procedure (AOR = 2.54;95%: 1.09,5.91), previous caesarian deliveries 4.90 (2.13,11.26) were found to be significantly associated with uterine rupture.

CONCLUSION

This finding showed that the prevalence of uterine rupture is higher. A more vigilant approach to prevent prolonged and obstructed labor, use of partograph, quick referral to a well-equipped center and prevention of other obstetrics complications need to be focused on.

Incidence of uterine rupture in second-trimester abortion with gemeprost alone compared to mifepristone and gemeprost

OBJECTIVES

To compare uterine rupture rates in women having a medical abortion receiving gemeprost alone to those receiving mifepristone plus gemeprost.

STUDY DESIGN

We reviewed the records of women undergoing medical abortion at 13 0/7-23 6/7 weeks from January 2007 to December 2014 at a single center in Italy. Prior to January 2011, we used gemeprost 1 mg vaginally every 3 h up to a maximum of five doses. After January 2011, we added mifepristone 200 mg orally 24 h prior to the same gemeprost protocol. The primary outcome of the study was the incidence of uterine rupture. We compared the outcome between women receiving gemeprost alone with the combination of gemeprost and mifepristone.

RESULTS

One thousand and sixty-one (58.5%) and 753 (41.5%) women underwent medical abortion in the gemeprost-alone and the gemeprost/mifepristone groups, respectively. Five (0.47%) uterine ruptures occurred in the gemeprost and four uterine ruptures occurred in the gemeprost/mifepristone groups, respectively (0.53%) (p=.89). All uterine ruptures occurred in women with prior cesarean delivery.

CONCLUSIONS

We rep orted no difference in the incidence of uterine rupture between the gemeprost-alone and gemeprost and mifepristone groups.

IMPLICATIONS

Uterine rupture is a rare complication of second-trimester medical abortion with gemeprost. Use of mifepristone prior to gemeprost does not affect this risk.

Incidence and factors associated with outcomes of uterine rupture among women delivered at Felegehiwot referral hospital, Bahir Dar, Ethiopia: cross sectional study

Background

Maternal mortality is a major public health challenge in Ethiopia. Uterine rupture is an obstetrical emergency with serious undesired complications for laboring mothers resulting in fatal maternal and neonatal outcomes. Uterine rupture has been contributing to high maternal morbidity and mortality. However, there is limited research on the factors and management outcomes of women with uterine rupture. Understanding the factors and management outcomes might delineate strategies to support survivors. Therefore the aim of this study is to assess the incidence and factors associated with outcomes of uterine rupture among laboring mothers at Felegehiwot Referral Hospital in Bahir Dar City, Northwest Ethiopia.

Methods

This is a cross sectional study with retrospective facility based data collection technique. All pregnant women who were managed for ruptured uterus at Felegehiwot referral hospital from September 11 2012 to August 30 2017 were included. The chart numbers of the women collected from operation theatre registers. Their case folders retrieved from the medical records room for analysis. Using structured check list, information on their sociodemography, booking status, clinical features at presentation and the place of attempted vaginal delivery was extracted. Data on the intraoperative findings, treatment, and associated complications and outcomes also collected. The collected data cleaned, coded and entered into EPI- Info version (7.1.2.0) and then exported in to SPSS Version 20.0 for analysis. Statistical comparison was done using chi square (X²). Strength of association between the explanatory variables and outcome variables described using odds ratio at 95% CI and P value less than 0.05. The results presented in tables.

Results

We studied 239 cases of uterine rupture in the 5 years period. Mothers without previous cesarean delivery including eight primigravidas took 87% of the cases. From all study participants, 54 of mothers (22.6%) developed undesired outcomes whereas 185(77.4%) discharged without major sequel. More than half (56.9%) arrived in hypovolemic shock. Total abdominal hysterectomy was the commonest procedure accounting for 61.5%. Duration of surgery was less than 2 h in 67.8% of the procedures. Anemia is the commonest complication (80.3%) followed by wound infection and VVF (11.7% each). There were 5 maternal deaths (2.1%). Mothers who had prolonged operation time (> 2 h) (AOR: 2.2, 95% CI: 1.10, 4.63) were significantly associated with undesired maternal outcomes after management of uterine rupture.

Conclusion

Incidence of ruptured uterus and its complications were high in the study area. It reflects the need for improvement in obstetric care and strong collaboration with referring health facilities to ensure prompt referral and management.

Predictors of uterine rupture in a large sample of women in Senegal and Mali: cross-sectional analysis of QUARITE trial data

Background

The purpose of this study was to investigate predictors of uterine rupture in a large sample of sub-Saharan African women. Uterine rupture is rare in high-income countries, but it is more common in low-income settings where health systems are often under-resourced. However, understanding of risk factors contributing to uterine rupture in such settings is limited due to small sample sizes and research rarely considers system and individual-level factors concomitantly.

Methods

Cross-sectional data analysis from the pre-intervention period (Oct. 1, 2007- Oct. 1, 2008) of the QUARITE trial, a large-scale maternal mortality study. This research examines uterine rupture among 84,924 women who delivered in one of 46 referral hospitals in Mali and Senegal. A mixed-effects logistic regression model identified individual and geographical risk factors associated with uterine rupture, accounting for clustering by hospital.

Results

Five hundred sixty-nine incidences of uterine rupture (0.67% of sample) were recorded. Predictors of uterine rupture: grand multiparity defined as > 5 live births (aOR = 7.57, 95%CI; 5.19–11.03), prior cesarean (aOR = 2.02, 95%CI; 1.61–2.54), resides outside hospital region (aOR = 1.90, 95%CI: 1.28–2.81), no prenatal care visits (aOR = 1.80, 95%CI; 1.44–2.25), and birth weight of > 3600 g (aOR = 1.61, 95%CI; 1.30–1.98). Women who were referred and who had an obstructed labor had much higher odds of uterine rupture compared to those who experienced neither (aOR: 46.25, 95%CI; 32.90–65.02).

Conclusions

The results of this large study confirm that the referral system, particularly for women with obstructed labor and increasing parity, is a main determinant of uterine rupture in this context. Improving labor and delivery management at each level of the health system and communication between health care facilities should be a priority to reduce uterine rupture.

Rupture of a myomectomy site in the third trimester of pregnancy after myomectomy, septoplasty and cesarean section: A case report

Uterine rupture during pregnancy is a rare but dangerous complication. A history of cesarean section is known to be a risk factor, but other types of uterine surgery can also increase the risk. We report a case of rupture of a myomectomy site in the third trimester of pregnancy without uterine contractions in a woman who had previously undergone myomectomy, septoplasty and cesarean section. The 39-year-old woman (gravida 2, para 2) presented at 29 weeks' gestation with uterine contractions. She was successfully treated with tocolytics. At 32 weeks of pregnancy, in the absence of contractions, the patient complained of severe abdominal pain and she became hypotensive. Emergency laparotomy and cesarean section were performed, resulting in the delivery of a live infant. The myomectomy site was found to have ruptured but the cesarean and septoplasty scars were intact. This case suggests that myomectomy scars are at greater risk of rupture during pregnancy than those resulting from cesarean section and septoplasty.

•

Previous cesarean, septoplasty and myomectomy are risk factors for uterine rupture.

•

The characteristics of uterine rupture depend on the types of surgery the woman has previously undergone.

•

After myomectomy, uterine rupture can occur during pregnancy without contractions.

•

Myomectomy may be a bigger risk factor for uterine rupture than cesarean section.

3-D Virtual Reconstruction of a Large Amniocele With Protrusion of Legs and Umbilical Cord Following Asymptomatic Uterine Rupture

BACKGROUND

Complete uterine rupture is a rare and severe intrapartum complication with high rates of maternal and fetal mortality. Asymptomatic uterine rupture is a very rare condition with one unique previous case described in the literature. Three-dimensional virtual models allow an immersive virtual reality of maternal-fetal structures with better understanding by the parents and the medical team.

CASE

We demonstrate a case of asymptomatic rupture uterine with a large amniocele and protruded legs and umbilical cord at 28 weeks of gestation by using a 3-D virtual model from ultrasound scan data.

CONCLUSION

3-D virtual models may be applied to the assessment of obstetric complications, thereby allowing a novel 3-D spatial view of maternal-fetal structures.
