Spontaneous uterine rupture complicated by bilateral pulmonary emboli: A case report

Spontaneous uterine rupture in unscarred uteri complicated by pulmonary emboli is a rare event with major maternal morbidity and mortality. This is a case of a 32-year-old woman, G1P0, at term, with no pertinent past medical/surgical history, who underwent an emergency cesarean delivery for failed induction of labor complicated by uterine rupture. Post-operatively, the patient was tachycardic and hypoxic. CT arteriogram revealed massive bilateral pulmonary emboli, and she was transferred for specialist care. An emergency pulmonary embolectomy and implantation of an extracorporeal right ventricular assist device were performed. Once the patient was clinically stable, an evaluation for thrombophilias and collagen disorders was done, and was positive for a variant of unknown significance in the ELN gene (c.205G > C). This case report highlights a potential connection between uterine ruptures, hemorrhage, and multiple, large pulmonary emboli. The authors propose a multidisciplinary discussion and evaluation to identify risk factors and biologic causes for these rare but life-threatening complications.

Placenta increta in an unscarred and bicornute uterus

Morbidly adherent placenta is a spectrum of obstetric complication which is life threatening to both mother and fetus. Congenital uterine malformation is a rare cause of such a condition. Here we present a case report of placenta increta in bicornute, unscarred uterus. An 18 year old para1+1 presented in emergency with history of vaginal delivery of still birth baby followed by vaginal bleeding with retained placenta. Her Examination under anaesthesia and failed attempt of manual removal of the placenta performed in emergency followed by Doppler ultrasound showed a bicornuate uterus with possibility of placenta increta, later this diagnosis was confirmed on magnetic resonance imaging (MRI). Patient managed with injection methotrexate along with folinic acid followed by removal of placenta under general anesthesia, hence we preserved her fertility. The aim of this report is to emphasize the importance of this rare but a possible association of nonscar and malformed uterus with spectrum of abnormal placentation. Obstetrician should run a full set of investigations in such cases to prevent maternal and fetal mortality and morbidity.

Idiopathic spontaneous rupture of unscarred uterus in a primigravida in active labour

Introduction

Rupture of unscarred pregnant uterus is a rare occurrence and its incidence is higher in developing countries. Rupture of unscarred uterus is associated higher likelihood of adverse maternal and fetal outcomes. Occurrence of rupture of an unscarred uterus lays foundation for the importance of supervised labour and to maintain a high index of suspicion even in a prim gravida.

Case report

We present a case of spontaneous rupture of unscarred uterus in a primigravida with no known risk factors. Rupture was diagnosed in second stage of labour when there was cessation of contractions and loss of station. On exploratory laparotomy, hemoperitoneum of 100 ml and a 10 cm tear was found in left posterolateral aspect of uterus. The tear was repaired successfully and patient had a normal post- operative course.

Discussion

Presence of a uterine scar is the key factor leading to rupture. Spontaneous rupture of unscarred uterus is a rare entity and is associated with multiple factors. In our case, all these factors were ruled out. In literature search we could find 15 cases of spontaneous rupture in unscarred uterus. According to our best knowledge this is the 7th case of rupture in unscarred uterus, reported in a prim gravida without any obvious risk factors.

Conclusion

Rupture uterus should be kept in mind in all patients, even in primigravida if there is high index of suspicion. Quick diagnosis and immediate laparotomy is the cornerstone of treatment in such cases.

•

Rupture of unscarred uterus is rare but is associated with significant morbidity.

•

High index of suspicion is needed even in absence of risk factors.

•

Immediate laparotomy is the gold standard management.

•

Delay in diagnosis and management can lead foeto-maternal morbidity.

Spontaneous rupture of an unscarred uterus in a woman at 37 weeks of pregnancy with abdominal pain: a case report

A 34-year-old gravida 2, para 1 woman at 37+4 weeks of pregnancy presented with abdominal pain. She had no medical history. Complete examination was unremarkable. After hours of monitoring, the patient abruptly deteriorated. An emergency cesarean delivery revealed a ruptured uterus with significant issues. Cautious monitoring is essential for such patients with atypical pain.

Uterine rupture in a gravid, unscarred uterus: A case report

•

The risk of uterine rupture in a gravid, unscarred uterus is largely unknown.

•

The risk factors for uterine rupture, when summed, can accumulate to a devastating and unforeseen end-result, such as fetal and maternal demise.

•

Low suspicion for rare occurrences such as uterine rupture in an unscarred uterus can delay diagnosis, with increased likelihood of fetal and maternal morbidity and mortality.

When advising a pregnant patient who has previously had a cesarean section about the risks of trial of labor, it is important to explain the risk of uterine rupture. Subjective symptoms of abdominal pain or objective findings of non-reassuring fetal status and loss of fetal station are often indicative of this disease process, which most commonly is caused by a defect on the uterus from the cesarean delivery. Any uterine surgical intervention (myomectomy, for example) is the leading risk factor for uterine rupture. This case report presents a patient who had no such history. However, the maternal and fetal clinical status rapidly deteriorated and required emergency cesarean delivery, at which point a complete uterine rupture was diagnosed. Low suspicion for rare occurrences such as uterine rupture in an unscarred uterus can delay diagnosis, with increased likelihood of fetal and maternal morbidity and mortality.

[Uterine rupture of the unscarred uterus: A report of 10 cases]

INTRODUCTION

Uterine rupture in the healthy uterus is a rare obstetrical complication, not much suspected and with badly identified risk factors. Thus, there exists frequent delay for treatment and therefore fetal-maternal important morbidity and mortality. This article describes clinical signs and symptoms, management, and maternal and neonatal prognosis of uterine rupture.

METHODS

Descriptive retrospective study within 13 maternity hospitals, reporting 10 series of cases of uterine rupture on gravid healthy uterus during the third trimester of pregnancy.

RESULT

The incidence was 2.8/100,000 births. Surgical treatment was conservative in 9 out of 10 cases, the maternal prognosis was good with no maternal deaths and 6 out of 7 patients had at least one subsequent pregnancy. The fetal prognosis was more reserved, with 2 fetal or neonatal deaths and 1 with motor disability. 6/6 patients (100%) had at least one iterative Caesarean section during the following pregnancies with healthy fetuses.

CONCLUSION

In this series of 10 cases over 25years, maternal-fetal morbidity and mortality were significant, in agreement with the literature. Maternal prognosis remained favorable. When surgical treatment is conservative a subsequent pregnancy is possible and an iterative cesarean section must be performed.

Rupture of the scarred and unscarred gravid uterus: Outcomes and risk factors analysis

OBJECTIVE

To study the maternal and fetal outcomes and assess the risk factors in patients with rupture at the lower-segment or non-lower-segment scarred, or unscarred gravid uterus.

MATERIALS AND METHODS

Gravid patients with uterine rupture were retrospectively collected in Chang-Gung Memorial Hospital from November 2004 to July 2017. The rupture timing and location in association with maternal and fetal outcomes were collected as well as the possible risk factors including surgical history and interval prior to conception were analyzed.

RESULTS

Thirty patients were included [mean age (±SEM), 34.4 ± 0.7 years; mean body mass index, 25.0 ± 0.6 kg/m²] with mean onset of rupture at 34.2 ± 0.9 weeks, in which, 12 occurred at term and 18 at preterm (range 20-34 weeks). Four fetal demises, 22 transferals to neonatal intensive care unit, and 17 maternal blood transfusions without maternal mortality were noted. Twenty-two patients presented with acute abdominal pain and/or abnormal fetal heart rate tracing were managed with emergent cesarean delivery. Four ruptures were found in postpartum of vaginal delivery, in which 3 were after trials of labor after cesarean delivery and 1 was unscarred uterus, and two of the four eventually underwent hysterectomy. Unscarred uterus (n = 6) without identifiable risk factor ruptured in significantly later gestation associated with higher fetal birthweights than those of the scarred uterus (n = 24) (both p < 0.05), both of which yielded morbidity. The rupture timing between patients of non-lower-segment scar (n = 14) and lower-segment scar (n = 10) were not significantly different.

CONCLUSION

Rupture of gravid uterus prevalently occurred after 30 weeks of gestation with remarkable morbidity. Unscarred uterus could rupture in later gestation than the scarred ones without identifiable risk factor. Alertness to the acute abdominal pain, atypical from uterine contraction or the suspicious fetal heart rate tracing is the key to the timely rescue and successful management.

Uterine rupture in a primigravid patient, an uncommon but severe obstetrical event: a case report

BACKGROUND

A spontaneous rupture of the unscarred uterus in a primigravid patient is extremely rare and is associated with high perinatal and maternal morbidity and mortality.

CASE PRESENTATION

A 34-year-old white primigravid woman, 31 + 3 weeks of gestation, presented with pre-eclampsia and developed a sudden acute abdomen. An emergency laparotomy was performed and a uterine rupture was found as the cause of the event. A stillborn girl was born.

CONCLUSION

A rupture of the pregnant uterus should always be considered in a pregnant woman presenting with abdominal pain, even in a primigravid patient.

Spontaneous postpartum rupture of an intact uterus: a case report

Rupture of uterus is an obstetrical complication characterized by a breach in the uterine wall and the overlying serosa. We report an unusual case of spontaneous rupture of an unscarred uterus in a 33-year-old woman, a day after her third successful vaginal delivery. A 33-year-old pregnant woman, gravid 3, para 3, was referred to our department at 39 gestational week because of rupture of membranes. Despite tocolysis administration, her pregnancy was delivered vaginally after 2 days, giving birth to a male neonate of 3,020 g with normal Apgar scores at first and fifth minute. Her uterus was intact and gynecological examination after delivery was normal without any potential signs or symptoms of pathology. However, the day following her labor, patient complained of left iliac fossa pain. Her blood tests revealed a CRP value at 27.6 mg/L, whereas the X-rays revealed an extensive impacted fecal mass in the colon. MRI revealed that the left lower myometrial part of the uterus was depicted abrupt, with simultaneous presence of hemorrhagic stuff. The decision of laparotomy was therefore made in order to further evaluate rupture of uterus and properly treat patient. And subtotal hysterectomy was performed. Postoperative follow-up period was not characterized by any complications and patient was finally discharged 4 days after hysterectomy.
