Rupture utérine bilatérale sur utérus gravide non cicatriciel en dehors du travail

We report a case of bilateral spontaneous uterine rupture of an unscarred uterus occured in a primigravida at 32 weeks to take care in our department after in utero transfert. Uterine rupture occurs mainly on scarred uterus during labor. This is an unfrequent but serious complication involving fetal–maternal prognosis in the absence of immediate care. We are conducting a review about spontaneous uterine rupture of unscarred uterus, before and during labor.     

Risks of induction of labour in women with a uterine scar from previous low transverse caesarean section

OBJECTIVE: Recent studies have shown that among women with uterine scars from previous caesarean section of any type, induction of labour is associated with increased risk of uterine rupture compared with spontaneous labour. We have assessed the risk of uterine rupture in a cohort of women with a previous low transverse caesarean section in whom induction and management of labour were performed according to a strict protocol. DESIGN: Cohort study. SETTING: University Hospital. POPULATION: All women with a singleton pregnancy and a previous low transverse caesarean section requiring induction of labour from 1/1/1992 to 12/30/2001 (n = 310) were compared with a control cohort during the same study period constituted of women with a previous low transverse caesarean section in spontaneous labour (n = 1011). METHODS: Clinical characteristics and rate of uterine rupture of women with previous caesarean section undergoing induction of labour were compared with those of women with previous caesarean section in spontaneous labour. MAIN OUTCOME MEASURE: Incidence of uterine rupture. RESULTS: Uterine rupture occurred in 0.3% in the previous caesarean section--induction group versus 0.3% in the previous caesarean section--spontaneous labour group (P = 0.9). Logistic regression analysis showed no significant difference in the rate of uterine rupture between the induction and spontaneous labour group (P = 0.67) after controlling for maternal age, parity, duration of labour, gestational age at delivery and birthweight. CONCLUSION: Among women with a previous low transverse caesarean section, induction of labour is not associated with significantly higher rates of uterine rupture compared with spontaneous labour, provided a consistent protocol with strict criteria for intervention is adopted.     

Expectant management of a herniated amniotic sac presenting as silent uterine rupture: a case report and literature review

Foetal membranes bulging into the abdominal cavity is a unique initial manifestation of silent or complete uterine rupture during pregnancy. Since silent uterine rupture has potential risk for complete uterine rupture, which leads to acute life-threatening complications for both the mother and baby, it is difficult to determine whether to manage expectantly or surgically, including repair of the uterine wall or termination of the pregnancy, especially in the early second trimester. We present here a case of a herniated amniotic sac with overstretched uterine wall of the fundus presenting as silent uterine rupture, which was incidentally detected on routine ultrasonography at 18 weeks' gestation in a 38-year-old primigravida with a history of myomectomy for diffuse uterine leiomyomatosis. Magnetic resonance imaging examination revealed that the myometrium thickness was fully maintained at the site of the foetal membranes ballooning. The pregnancy was therefore managed expectantly and continued to successful delivery at 30 weeks' gestation. The precise assessment of the uterine wall may be essential to manage a herniated amniotic sac presenting as silent uterine rupture and to optimise the outcome of the pregnancy. We review all cases of a herniated amniotic sac out of focally overstretched uterine wall before 34 weeks' gestation.     

Pregnancy in primigravida complicated by premature rupture of membranes in 15th week of pregnancy with successful delivery outcome of the mature newborn--case report and review of the literature

Premature rupture of membranes and amniotic fluid leakage is a very serious complication of pregnancy. In most cases it causes the premature contractile activity of uterine muscle and premature labour. It is a very rare situation when after premature rupture of membranes at less than 20 weeks of gestation it is possible to carry pregnancy to term with a successful delivery outcome of healthy mature infant. In the study we analysed the course of pregnancy in 28 years old primigravida with PROM from 15th week of pregnancy with a successful delivery outcome of mature newborn in 37th week of gestation. Our analysis revealed that in certain cases of premature rupture of membranes it is possible to successfully prolong the duration of pregnancy till the foetus matures. It seems necessary to improve the management which allows to prolongate the duration of pregnancy in premature rupture of membranes.     

Spontaneous prelabor uterine rupture in a primigravida: a case report and review of the literature

A rare case of prelabor uterine rupture in a primigravida was reported. A woman with a history of uterine perforation during hysteroscopy became pregnant after donor oocyte in vitro fertilization. To provide more insight into the possible risk factors for prelabor uterine rupture in primigravidae, a literature review was performed.     

Rupture of the uterine scar during term labour: contractility or biochemistry?

OBJECTIVE: Vaginal birth after a prior low transverse caesarean section (VBAC) is advocated as a safe and effective method to reduce the total caesarean section rate. However, the risk of uterine rupture has dampened the enthusiasm of practising clinicians for VBAC. Uterine rupture occurs more frequently in women receiving prostaglandins in preparation for the induction of labour. We hypothesised that similar to the cervix, prostaglandins induces biochemical changes in the uterine scar favouring dissolution, predisposing the uterus to rupture at the scar of the lower segment as opposed to elsewhere. DESIGN: We tested aspects of this hypothesis by investigating the location of uterine rupture associated with prostaglandins and compared it with the sites of rupture in the absence of prostaglandins. SETTINGS: Two North American University Hospitals. POPULATION: Twenty-six women with a prior caesarean section, experiencing uterine rupture in active labour. METHODS: Retrospective review of all pregnancies complicated by uterine rupture at two North American teaching hospitals from 1991 to 2000. MAIN OUTCOME MEASURE: Site of the uterine rupture. RESULTS: Thirty-four women experienced rupture after a previous caesarean section with low transverse uterine incision. Ten of the women who ruptured (29%) received prostaglandins for cervical ripening (dinoprostone: n= 8 or misoprostol: n= 2) followed by either spontaneous contractions (n= 3) or oxytocin augmentation during labour (n= 7). In 16 women (47%), oxytocin alone was sufficient for the induction/augmentation of labour. Eight (23%) women ruptured at term before reaching the active phase of labour in the absence of pro-contractile agents or attempted VBAC. There were no differences among the groups in terms of age, body mass index, parity, gestational age, fetal weight or umbilical cord pH measurements. Women treated with prostaglandins experienced rupture at the site of their old scar more frequently than women in the oxytocin-alone group whose rupture tended to occur remote from their old scar (prostaglandins 90%vs oxytocin 44%; OR: 11.6, 95% CI: 1.2-114.3). CONCLUSION: Women in active labour treated with prostaglandins for cervical ripening appear more likely to rupture at the site of their old scar than women augmented without prostaglandins. We propose that prostaglandins induce local, biochemical modifications that weaken the scar, predisposing it to rupture.     

Obstetric uterine rupture: a four-year clinical analysis.

OBJECTIVE: The purpose of our study was to identify the risk factors of uterine rupture during labour, to report maternal and neonatal outcome, and to propose preventive measures. STUDY DESIGN: A retrospective study with review of patients' files and monitor strips was performed. RESULTS: Between January 1, 1994 and November 30, 1998, there were 21 cases of uterine rupture at our institution. Of these, 6 patients had complete rupture, and 15 had incomplete rupture. The risk of uterine rupture was increased in patients who had a history of one or more Caesarean sections, obstructed labour, dysfunctional labour, and those who had injudicious use of uterine stimulants. There was no maternal death and fetal loss was 7 (33.3%). CONCLUSIONS: The high incidence of uterine rupture is attributed to lack of prenatal care, labour in high-risk patients outside hospital because of declining economy, and more patients with two or more previously scarred uterus. The maternal and neonatal complications have remained very high in the developing countries. We recommend that all patients with a history of Caesarean delivery should be delivered in hospital and observed closely for progression of labour, recognition of an active phase arrest requires operative delivery.     

Uterine Rupture During Labour in a Primigravida

EDITORIAL COMMENT: We accepted this case for publication because it will interest readers. Certainly the woman had a haemoperitoneum and signs indistinguishable from a case of rupture of the uterus although technically this is not a rupture because the tear did not extend through the uterine wall to the endometrial cavity. The editor saw a patient some 38 years ago who had a haemoperitoneum and who came to laparotomy on 2 occasions where it appeared that the bleeding had come from a tear in the peritoneum between the uterosacral ligaments. This patient died during her third laparotomy. There is also literature describing tears in the peritoneum over the uterosacral ligaments as a cause of chronic pelvic pain. The editorial committee find it feasible that a patient in labour can develop a tear in the peritoneum and superficial myometrium in her posterior uterine wall which if it involved vessels could cause a life-threatening haemoperitoneum. Of course similar tears occur due to trauma such as a motor-car accident when the woman is wearing a seat belt which can localize trauma to the uterus.
Summary: Uterine rupture ie extremely rare in the absence of any of the commonly recognized risk factors. We describe here a case of incomplete uterine rupture in a woman in her first pregnancy who had no previous instrumentation to the genital tract. Her only significant history was that of 2 episodes of minor antepartum haemorrhage occurring prior to induction of labour with artificial rupture of membranes and intravenous oxytocin. The rupture was manifested by 450 mL blood in the peritoneal cavity when an emergency Caesarean section was performed for persistent fetal bradycardia.     

Uterine rupture: preventable obstetric tragedies?

BACKGROUND: Although ruptured uterus is nowadays a rare obstetric emergency in Western countries, it is still alarmingly common in developing countries, where it remains a major cause of maternal mortality and morbidity. AIMS: To review the recent experience of uterine rupture at a tertiary obstetric unit in eastern Nepal and to recommend improvements in the current management of labour, especially obstructed labour, in a poorly resourced country. METHODS: All cases of uterine rupture managed from March 2002 to March 2006 were identified retrospectively, and details were retrieved from medical records. RESULTS: Fifty-two women suffered from uterine rupture during the four-year period, approximately one woman per month. Most were unbooked multigravidae, with no antenatal care. They nearly all began labour at home in the absence of a skilled birth attendant. After prolonged labour, usually prolonged second stage, various interventions had often been attempted at home or in other health facilities before admission. Most were shocked and required urgent laparotomy and blood transfusion. Many required intensive care and ventilatory support. Forty-six per cent required hysterectomy and 5.8% subsequently suffered from a urogenital fistula. The maternal mortality rate in this series was 13.5%, and the stillbirth rate was 94.2%. CONCLUSIONS: Unsafe obstetric practices were identified, especially the injudicious use of oxytocic drugs and fundal pressure in prolonged second stage. Several achievable improvements in obstetric care are recommended, particularly aimed at reducing the delay in women reaching emergency obstetric care when labour is prolonged.     

Uterine rupture in a primigravida with adenomyosis recently subjected to laparoscopic resection of rectovaginal endometriosis: case report

A case of intrapartum, complete, low-posterior wall, transverse uterine rupture, complicated by uterine atony and treated by emergency hysterectomy in a primigravida with uterine adenomyosis who delivered vaginally at 37 weeks plus 5 days of gestation, 9 months after undergoing laparoscopic resection of rectovaginal septum endometriosis.     

Evaluation of endocervical, first-void urine and self-administered vulval swabs for the detection of Chlamydia trachomatis in a miscarriage population

BACKGROUND: The issues related to safety of induction of labour in women with previous caesarean section remain controversial. The main adverse outcome fuelling this debate is a "small" risk of uterine rupture that is potentially devastating for both the mother and the fetus. OBJECTIVE: To estimate the risk of uterine rupture or dehiscence in women who require induction of labour with previous caesarean sections. DESIGN: Five year retrospective review of computerised hospital records and case note review of index cases. SETTING: Large inner city teaching hospital. POPULATION: Two hundred and five women who had their labour induced with history of one lower segment caesarean section. METHODS: This study was conducted at Liverpool Women's Hospital, a tertiary referral centre, with approximately 6000 births per annum. We searched the hospital's computerised records of deliveries from June 1997 to June 2002 and reviewed all indications and outcomes of induction of labour in women with one previous caesarean section. Women with singleton pregnancy and cephalic presentation were then divided into three groups: those with one previous caesarean section and no previous vaginal deliveries, those whose last delivery was a caesarean section but had delivered vaginally before and those whose last delivery was by vaginal route, but had had one caesarean section in the past. MAIN OUTCOME MEASURES: Uterine rupture or dehiscence, adverse neonatal outcome. RESULTS: Two hundred and five women were included. There were four cases of uterine rupture and one dehiscence (2.4%, 95% CI 0.8-5.6%). Two babies were profoundly acidotic at birth, but all five neonates were healthy when discharged from hospital with no long term morbidity. All five cases occurred in the group of women with no previous vaginal deliveries. The intrauterine pressure catheter recordings had contributed to the diagnosis of uterine rupture/dehiscence in three out of five cases. CONCLUSION: In women with previous caesarean section and no vaginal deliveries, induction of labour carries a relatively high risk of uterine rupture/dehiscence despite all precautions, including intrauterine pressure monitoring.     

Placenta percreta: report of two cases and review of the literature

Placenta percreta is a serious complication of pregnancy. Two cases of placenta percreta confirmed histologically were treated by supravaginal hysterectomy. Case 1: A case of uterine rupture secondary to placenta percreta was diagnosed in a 29-year-old term primigravida during an elective abdominal delivery of a healthy fetus. Spontaneous rupture of the primigravid uterus due to placenta percreta without a history of trauma or infection is a very rare occurrence. Case 2: A 33-year-old previously healthy G4P2 woman was admitted at 29 weeks of gestation with acute abdominal pain and hemorrhagic shock. There was a history of one induced abortion and two cesarean section deliveries. A review of risk factors, diagnostic tools and treatment possibilities are given.     

Premature rupture of fetal membranes at term: sequelae of conservative management. An analysis of a personal patient sample

Few procedures are less standardised than the procedure in case of pre-labour rupture of the membranes at term (PROM). We propose that management should be reviewed regularly on the basis of one's own data and be modified accordingly if necessary. For the duration of three months we analysed 400 pregnancies retrospectively. Patients with PROM were observed expectantly for 24 hours. If there were no spontaneous uterine contractions, labour was induced, depending on the degree of cervical dilatation. 10 percent of the cases studied had PROM. Of these a high proportion of 73 percent were primigravida, likewise 73 percent had an unripe cervix. The average time between PROM and delivery was 27 h. 50 percent of the babies were born 24 h after PROM. If delivery occurred more than 24 h after PROM, the rate of caesarean section (15 vs. 30 percent), the rate of forceps deliveries (11 vs. 20 percent), the rate of amnionitis (16 vs. 35 percent) and the number of admissions to the newborn-ICU (16 vs. 25 percent) almost doubled. The patients were examined vaginally relatively often prior to delivery (up to 18 times, with a mean of 8 times). We therefore recommend active management 6-8 h after PROM, should there be no onset of spontaneous uterine contractions. This is particularly beneficial to primigravida with an unripe cervix.     

Spontaneous uterine rupture with amniotic sac protrusion at 28 weeks subsequent to previous hysteroscopic metroplasty

BACKGROUND: Hysteroscopic metroplasty improves pregnancy outcome in case of uterine septum. Uterine rupture during a pregnancy following this procedure may occur. CASE: A patient with a history of hysteroscopic resection of a uterine septum complicated by fundal perforation, presented at 28 weeks a spontaneous uterine rupture with amniotic sac protrusion through the uterine wall disruption. CONCLUSION: Uterine rupture during pregnancy following a hysteroscopic metroplasty may occur even though it appears to be a very uncommon event. Patients who have had this procedure should be aware of this potential risk in case of future pregnancies. How to avoid such complication is still unclear.     

Vaginal birth after Caesarean section: an Australian multicentre study. VBAC Study Group

Retrospective analysis of medical records and individual case review was undertaken at 11 major obstetric hospitals for a 5 year period from July 1992 to June 1997 to investigate rates of vaginal birth after Caesarean section (VBAC), the occurrences of uterine rupture, and the outcomes for mother and infant following rupture. Total deliveries were 234,015, of which 21,452 or 9.2% were associated with one or more previous Caesarean sections. Within this scar group, 5419 patients or 25.3% were delivered vaginally. There were 62 cases of significant uterine rupture with no maternal deaths. Perinatal mortality with rupture was 25% and serious maternal complications (usually hysterectomy) occurred in 25% of those with uterine rupture. In women attempting vaginal delivery after a previous lower segment Caesarean section, the uterine rupture rate was estimated at 0.3%, with 0.05% experiencing a perinatal death and 0.05% requiring a hysterectomy. Although VBAC rates in Australia remain lower than many overseas reported series, rates are increasing. While rupture continues to be associated with serious adverse outcomes, the incidence of rupture during trial of labour is low and appears to be associated with a better outcome than rupture of an unscarred uterus.     

Uterine Vein Rupture at Delivery as a Delayed Consequence of Laparoscopic Surgery for Endometriosis: A Case Report

Laparoscopic resection of deep infiltrating endometriosis (DIE) has been reported to be an effective method for reduction of endometriosis-associated pain. As its complications, bowel perforation, urinary tract injury and neurogenic bladder are well known; however, uterine vein rupture during pregnancy has not been reported previously. We encountered a case of hemoperitoneum resulting from uterine vein rupture at a delivery as a delayed consequence of laparoscopic resection of DIE. A 31-year-old, para 2 woman underwent laparoscopic resection of lateral pelvic peritoneum, uterosacral ligaments, and bilateral endometriomas, exposing uterine vessels, which we covered with fibrin glue. Endometriosis-associated pain disappeared, and then the patient conceived 4 months later. The course of pregnancy and induction of labor with controlled oxytocin infusion was uneventful, and the patient delivered a female baby without asphyxia. Immediately after delivery, low abdominal pain with hypotension occurred despite absence of abnormal vaginal bleeding. Ultrasonography and the blood hemoglobin value suggested hemorrhagic shock owing to hemoperitoneum; therefore emergency exploratory laparotomy was performed. Active bleeding was found at the right uterine vein, which was then sutured for hemostasis. The patient received a blood transfusion and recovered without any problems. The bleeding lesion was located at the vein on which the peritoneum had been removed at the first laparoscopy, which suggested that the operation for DIE included a risk of uterine vessel rupture during pregnancy.     

Rupture of the primigravid uterus: a review of the literature

Uterine rupture is a catastrophic obstetric complication, associated with high rates of perinatal morbidity and mortality. The most common risk factor is previous uterine surgery, and most cases of uterine rupture occur in women with a previous cesarean delivery. Traditionally, the primigravid uterus has been considered almost immune to spontaneous rupture. In fact, although spontaneous rupture of the primigravid uterus is indeed a very rare event, a number of such cases have been reported recently. Prompt recognition of uterine rupture and expeditious recourse to laparotomy are critical in influencing perinatal and maternal morbidity. Not all uterine ruptures present with the typical clinical picture of abdominal pain, hypovolemia, vaginal bleeding, and fetal compromise. Therefore, it is important to maintain a high index of suspicion for uterine rupture in women presenting with some, or all, of these features, regardless of parity. Here we provide a systematic review of cases of spontaneous uterine rupture in primigravid women reported in the literature to date. Clinical presentation, differential diagnosis, common etiological factors, complication rates, and appropriate management of this rare obstetric event are discussed. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to recall that uterine rupture in a primigravida is a rare event, without typical signs and symptoms, and explain that the morbidity and mortality of the mother and child is directly related to a high index of suspicion and prompt treatment by the clinician.     

Rupture of the uterus during labor without apparent cause

Spontaneous uterine rupture at term during labor of a non-scarred uterus under epidural anaesthesia is reported in a 17-yr-old primigravida. This exceptional event may lead to catastrophic maternal and fetal consequences. The authors discuss the prevention and diagnosis of this obstetrical complication.     

Uterine rupture and its complications in the Netherlands: a prospective study

OBJECTIVE: To determine maternal and perinatal morbidity and mortality after uterine rupture in the Netherlands. STUDY DESIGN: All 100 Dutch obstetric departments were asked to participate in a prospective nationwide registration of uterine rupture between 1st April 2002 and 1st April 2003. For every case, a questionnaire about obstetrical history, current pregnancy and delivery, maternal and neonatal outcome was completed. RESULTS: Eighty-nine percent of all hospitals in the Netherlands participated. Ninety-eight uterine ruptures were registered; 95 after a previous caesarean section (CS) of which 91 occurred during a trial of labour. The fetus was extruded in the abdominal cavity completely in 18 cases and partially in 13 cases. Major complications due to uterine rupture were: perinatal death (n=11, from 94 cases with a viable fetus, 11.7%) and hysterectomy (n=4, 4.1%). CONCLUSION: These severe complications, perinatal death and hysterectomy, have to be an issue when counselling women on an elective CS and women with a history of a CS on the route of delivery.
