Spontaneous uterine rupture with amniotic sac protrusion during the third trimester of a unicornuate uterus pregnancy: A rate case report

RATIONALE

Uterine rupture is an obstetrical emergency associated with severe maternal and fetal mortality. It is rare in the unscarred uterus of a primipara.

PATIENT CONCERNS

A 25-year-old woman in her 38th week of gestation presented with slight abdominal pain of sudden onset 10 hours before. An emergency cesarean section was done. After surgery, the patient and the infant survived.

DIAGNOSES

With slight abdominal pain of clinical signs, ultrasound examination showed that the amniotic sac was found in the peritoneal cavity with a rupture of the uterine fundus.

INTERVENTIONS

Uterine repair and right salpingectomy.

OUTCOMES

After surgery, the patient and the infant survived. The newborn weighed 2600 g and had an Apgar score of 10 points per minute. Forty-two days after delivery, the uterus recovered well.

LESSONS

Spontaneous uterine rupture should be considered in patients even without acute pain, regardless of gestational age, and pregnancy with abdominal cystic mass should consider the possibility of uterine rupture.

Uterine rupture in patients with a history of hysteroscopy procedures: Case series and review of literature

RATIONALE

Uterine rupture during pregnancy poses significant risks to both the fetus and the mother, resulting in high mortality and morbidity rates. While awareness of uterine rupture prevention after a cesarean section has increased, insufficient attention has been given to cases caused by pregnancy following hysteroscopy surgery.

PATIENT CONCERNS

We report 2 cases here, both of whom had a history of hysteroscopy surgery and presented with severe abdominal pain during pregnancy.

DIAGNOSES

Both patients had small uterine ruptures, with no significant abnormalities detected on ultrasonography. The diagnosis was confirmed by a CT scan, which showed hemoperitoneum.

INTERVENTIONS

We performed emergency surgeries for the 2 cases.

OUTCOMES

We repaired the uterus in 2 patients during the operation. Both patients recovered well. The children survived. No abnormalities were detected during their follow-up visits.

LESSONS

Attention should be paid to the cases of pregnancy after hysteroscopy.

Silent uterine rupture in the term pregnancy: Three case reports

RATIONALE

Uterine rupture is extremely hazardous to both mothers and infants. Diagnosing silent uterine rupture in pregnant women without uterine contractions is challenging due to the presence of nonspecific symptoms, signs, and laboratory indicators. Therefore, it is crucial to identify the elevated risks associated with silent uterine rupture.

PATIENT CONCERNS

on admission, case 1 was at 37 gestational weeks, having undergo laparoscopic transabdominal cerclage 8 months prior to the in vitro fertilization embryo transfer procedure, case 2 was at 38 4/7 gestational weeks with a history of 5 previous artificial abortion and 2 previous vaginal deliveries, case 3 was at 37 6/7 gestational weeks with a history of laparoscopic myomectomy.

DIAGNOSES

The diagnosis of silent uterine rupture was based on clinical findings from cesarean delivery or laparoscopic exploration.

INTERVENTIONS

Case 1 underwent emergent cesarean delivery, revealing a 0.25 cm × 0.25 cm narrow concave area above the Ring Ties with active and bright amniotic fluid flowing from the tear. Case 2 underwent vaginal delivery, and on the 12th postpartum day, ultrasound imaging and magnetic resonance imaging revealed a 5.8 cm × 3.3 cm × 2.3 cm lesion on the lower left posterior wall of the uterus, and 15th postpartum day, laparoscopic exploration confirmed the presence of an old rupture of uterus. Case 3 underwent elective cesarean delivery, revealing a 3.0 cm × 2.0 cm uterine rupture without active bleeding at the bottom of the uterus.

OUTCOMES

The volumes of antenatal bleeding for the 3 patients were approximately 500 mL, 320 mL, and 400 mL, respectively. After silent uterine ruptures were detected, the uterine tear was routinely repaired. No maternal or neonatal complications were reported.

LESSONS

Obstetricians should give particular consideration to the risk factors for silent uterine rupture, including a history of uterine surgery, such as laparoscopic transabdominal cerclage, laparoscopic myomectomy, and induced abortion.

Spontaneous second trimester rupture of a previous caesarean section scar: A case report

Spontaneous uterine rupture before the onset of labour is rare in pregnancy especially before the third trimester. It is life threatening with devastating consequences to the mother and fetus. We report a case of spontaneous second trimester uterine rupture in a multipara with a previous uterine scar with the aim of creating awareness and sharing the challenges in diagnosis and management of this unusual complication of pregnancy. A 34-year-old woman with two previous deliveries presented at 16 weeks gestation with abdominal pain and vaginal bleeding of one day duration. At presentation, she was pale and in shock. There was generalized abdominal tenderness with guarding and rebound tenderness. At laparotomy, there was uterine rupture involving the lower segment with right lateral upward extension which was repaired. She remained stable at the follow up visit. In conclusion, Spontaneous uterine rupture of a previous caesarean section scar in the second trimester is rare. The diagnosis should be considered in a woman with previous caesarean section who experience an acute abdomen in the second trimester of pregnancy.

Uterine rupture in the first trimester: a case report and review of the literature

BACKGROUND

Uterine rupture is a rare complication that can occur in the first trimester of pregnancy. It can lead to serious maternal morbidity or mortality, which is mostly due to catastrophic bleeding. First trimester uterine rupture is rare; hence, diagnosis can be challenging as it may be confused with other causes of early pregnancy bleeding such as an ectopic pregnancy. We present a case of first trimester scar dehiscence and conduct a literature review of this rare condition.

CASE PRESENTATION

A 39-year-old African patient with four previous hysterotomy scars presented with severe lower abdominal pain at 11 weeks of gestation. She had two previous histories of third trimester uterine rupture in previous pregnancies with subsequent hysterotomies and repair. She underwent a diagnostic laparoscopy that confirmed the diagnosis of a 10 cm anterior wall uterine rupture. A laparotomy and repair of the rupture was subsequently done.

CONCLUSION

In conclusion, the case presented adds to the body of evidence of uterine scar dehiscence in the first trimester. The risk factors, clinical presentation, diagnostic imaging, and management outlined may help in early identification and management of this rare but life threatening condition.

Uterine rupture of an unscarred gravid uterus at term attributed to adenomyosis

Uterine rupture is a rare obstetric emergency that is typically associated with the presence of scar tissue such as in the case of previous caesarean section. In this case report, a primigravid patient presented to the hospital in cardiac arrest with massive haemoperitoneum secondary to a posterior uterine rupture. The histological specimen was found to have diffuse adenomyosis at the site of rupture. On review of the literature, there is insufficient evidence to suggest we as clinicians should alter the antenatal care for patients with known adenomyosis; however, this case highlights how we should have a high index of suspicion for those presenting with signs and symptoms of uterine rupture with known adenomyosis in the absence of other risk factors.

Unscarred uterine rupture with catastrophic hemorrhage immediately after vaginal delivery: diagnosis and management of six consecutive cases

BACKGROUND

To describe and explore the risk factors, clinical presentations, timely diagnostic approaches, and management in patients experiencing unscarred uterine rupture with catastrophic hemorrhage.

METHODS

We retrospectively analyzed clinical and imaging data from women who encountered postpartum hemorrhage (PPH) and were diagnosed with unscarred uterine rupture within a three-year timeframe (2018-2020). The data were extracted from medical records obtained from a multi-hospital 24-hour emergency PPH transfer system.

RESULTS

Six patients were identified as having unscarred uterine rupture after vaginal delivery. All six women were para 2, with four of them undergoing vacuum-assisted delivery. One patient experienced out-of-hospital cardiac arrest (OHCA), while five patients presented with hypovolemic shock. Abdominopelvic ultrasound revealed a boggy lower uterine segment. Initially, five patients underwent transarterial embolization (TAE) of the internal iliac arteries in an attempt to achieve hemostasis, but this approach proved unsuccessful. Abdominopelvic computed tomography (CT) confirmed the diagnosis of ruptured uterus by demonstrating disrupted myometrium and hemoperitoneum. Immediate exploratory laparotomy followed by life-saving hysterectomy was performed in all cases. The median estimated total blood loss was 2725 mL ± 900 mL (ranging from 1600 mL to 7100 mL). Lower segment lacerations were observed in all patients, with more extensive uterine damage noted in those who underwent vacuum extraction. The length of hospital stay varied between 9 and 38 days.

CONCLUSION

Instrument-assisted obstetric delivery is a possible contributing factor to unscarred uterine rupture in our study. In specific cases, the use of abdominopelvic CT prior to initiating transarterial embolization (TAE) offers valuable information to complement ultrasound findings. This comprehensive approach helps in accurately identifying the underlying cause of intractable postpartum hemorrhage (PPH). Immediate conversion to laparotomy is essential to explore the intra-abdominal factors causing PPH that cannot be controlled by TAE. The rational etiologies of uterine rupture must be clarified while generating practical guideline in the future.

Cornual pregnancy rupture and massive hemorrhage: A case report

BACKGROUND

Corneal pregnancy is rare and difficult to detect in the early stages. Due to the abundant blood supply in this area, a rupture can result in massive internal bleeding, shock, and even death. Therefore, immediate surgery is necessary, and patients must replenish their blood volume as soon as possible to ensure blood supply to important organs. For those whose blood pressure cannot immediately rise, surgery should be performed while resisting shock to buy time.

CASE SUMMARY

We present the case of a 34-year-old Chinese woman at 19 weeks of gestation who had a corneal pregnancy. No abnormalities were detected in the examinations in the first trimester. This patient was 19 weeks pregnant and sought medical advice due to sudden lower abdominal pain, syncope, and hemorrhagic shock. After rescue and treatment, she recovered and was discharged from the hospital, afterwards, the patient gave birth to a child 7 years later.

CONCLUSION

The early diagnosis of cornual pregnancy is mainly based on ultrasound. However, there is a high incidence of missed diagnosis and misdiagnosis of this disease. Patients may face serious and life-threatening conditions in case of the rupture of cornual pregnancy. This disease can be mainly treated by surgery.

Spontaneous rupture of an unscarred uterus during pregnancy: A rare but life-threatening emergency: Case series

RATIONALE

In most cases, uterine rupture occurs during the third trimester of pregnancy or during labor. Even fewer reports have been published about the occurrence of this condition without a gynecologic history of any surgical procedure. Due to their scarcity and variable clinical presentation, early diagnosis of uterine rupture may be difficult, and if the diagnosis is not timely, the condition may be life-threatening.

PATIENT CONCERNS

Herein, 3 cases of uterine rupture from a single institution are described. Three patients are at different gestational weeks and all have no history of uterine surgery. They came to the hospital due to acute abdominal pain, which is characterized by severe and persistent pain in the abdomen, with no apparent vaginal bleeding.

DIAGNOSES

All 3 patients were diagnosed with uterine rupture during the operation.

INTERVENTIONS

One patient underwent uterine repair surgery; while the other 2 underwent subtotal hysterectomy due to persistent bleeding and pathological examination after surgery confirmed placenta implantation.

OUTCOMES

The patients recovered well after the operation, and no discomfort occurred in the follow-up.

LESSONS

Acute abdominal pain during pregnancy can pose both diagnostic and therapeutic challenges. It is important to consider the possibility of uterine rupture, even in cases where there is no history of prior uterine surgery. The key to the treatment of uterine rupture is to shorten the diagnosis time as much as possible, this potential complication should be carefully monitored for and promptly addressed to ensure the best possible outcomes for both the mother and the developing fetus.

[Uterine rupture during medical termination of pregnancy or intrauterine death: A risk management study]

OBJECTIVE

To describe and analyze a series of uterine ruptures (UR) that occurred in the context of medical termination of pregnancy (MTP) or intrauterine death (IUD) from a risk management perspective.

METHODS

French retrospective descriptive observational study of all cases of UR occurring during induction for IUD or MTP, reported between 2011 and 2021 by Gynerisq. Cases were recorded on a basis of voluntary reports using targeted questionnaires.

RESULTS

Between November 27, 2011, and August 22, 2021, 12 cases of UR occurring during an induction for IUD or MTP were recorded. 50 % of the patients had never given birth by cesarean section. The term of delivery varied from 17+3 days to 41+2 days. The clinical signs found were pain (n=6), ascending fetal presentation (n=5) and bleeding (n=4). All patients were managed by laparotomy, 5 were transfused. One vascular ligation and one hysterectomy were required.

CONCLUSION

Knowledge of surgical history is involved in the prevention of UR. The signs of detection are pain, ascending presentation and bleeding. The speed of management and good teamwork allow a reduction of maternal complications. The findings of the morbidity and mortality reviews show that prevention and mitigation barriers can be established.

[Traumatic uterine rupture in gemelli pregnant woman causing emergency hysterectomy]

This is a case report of a 30-year-old gemelli pregnant woman in gestation week 15 and 6 days, who was admitted to a local hospital after being involved in a high impact motor vehicle accident. Traumatic uterine rupture was suspected and the patient was immediately operated with exploratory laparotomy. Emergency hysterectomy was performed, hence the pregnancy was terminated. This case is a rare obstetric trauma situation, and prompt diagnosis is life-saving.

Clinical Features, Management and Maternal-Infant Prognosis in Patients with Complete Uterine Rupture in the Second and Third Trimester of Pregnancy

OBJECTIVES

Our study aimed to investigate the clinical features, management, and maternal-infant prognosis in patients with complete uterine rupture in the second and third trimester of pregnancy.

METHODS

A total of 15 patients with complete uterine rupture in their second and third trimester of pregnancy who were admitted to our hospital between January 2012 and December 2020 were included in our study. The patients enrolled were divided into the scar group (11 patients) and the non-scar group (4 patients) according to the existence or absence of a uterine scar. The general data, clinical characteristics and follow-up results in the 2 groups were compared.

RESULTS

There was no significant difference in age, pregnancy duration or delivery cycle between the 2 groups (P > .05). The incidence of original scar rupture in the scar group was significantly higher than in the non-scar group (P > .05). No significant difference was found in clinical characteristics between the scar and the non-scar groups (P > .05). The most common clinical features included abdominal pain, inability to lie flat, hemorrhagic shock, prenatal vaginal bleeding and uterine rupture, mostly occurring in the lower segments of the uterus and cervix. A total of 3 patients were misdiagnosed as having surgical disease. After completing relevant examinations, the uterine rupture was repaired surgically; the patients were discharged after blood transfusion, and their condition resolved. In all, 3 patients in the non-scar group and 1 patient in the scar group were transferred to the intensive care unit (ICU). All 15 patients were discharged after treatment. Follow-up was completed by all patients for 12 to 36 months, with an average follow-up time of 23.09 ± 2.19 months. Of the 15 patients, 2 underwent induced abortion after 24 months due to unplanned pregnancy. A 5-minute Apgar score of ≤7 in the scar group was higher than that in the non-scar group, but the difference was not statistically significant (P > .05). Perinatal mortality in the 15 patients was 40.00% (6/15).

CONCLUSION

The most common clinical features in patients with complete uterine rupture in the second and third trimester of pregnancy included abdominal pain, inability to lie flat, hemorrhagic shock, prenatal vaginal bleeding and uterine rupture, mostly occurring in the lower segments of the uterus and cervix. In addition, a remarkably worse maternal-infant prognosis was seen in patients with complete uterine rupture in the second and third trimester of scarless pregnancy compared with patients with complete uterine rupture in the second and third trimester of scarred pregnancy.

[Establish and application of scoring scale for trial of labor after cesarean section]

Objective: To establish a scoring scale for trial of labor after cesarean section (TOLAC), to explore the evaluation ability of this scoring scale for vaginal delivery after cesarean section (VBAC), and to improve the success rate of TOLAC. Methods: The delivery information of 661 TOLAC pregnant women admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from 2014 to 2017 was retrospectively analyzed, and the TOLAC scoring scale was established by referring to relevant literatures. A prospective cohort study of pregnant women with TOLAC from January 2018 to December 2019 in Zhengzhou Central Hospital was conducted, including 440 pregnant women who were excluded from contraindications in trial labor. According to TOLAC scoring scale, pregnant women were divided into 3 groups, 0-6 group (94 cases), 7-9 group (234 cases) and 10-15 group (112 cases). The success rate of trial labor, failure reasons and incidence of maternal and neonatal complications were compared among the three groups. Results: (1) The overall success rate of TOLAC in 440 pregnant women was 75.0% (330/440). The success rates of 0-6, 7-9 and 10-15 groups were 53.2% (50/94), 76.9% (180/234) and 89.3% (100/112), respectively. The success rate of 10-15 group were significantly higher than those of 0-6 and 7-9 groups (all P<0.05). (2) Among the causes of trial labor failure, there were statistically significant differences between the three groups in terms of threatened uterine rupture and maternal abandonment (all P<0.05). Pairings showed that the incidences of threatened uterine rupture and maternal abandonment in 0-6 group was lower than those in 7-9 and 10-15 groups, and the differences were statistically significant (all P<0.05). (3) Maternal and neonatal complications mainly included postpartum hemorrhage and neonatal asphyxia, but there were no significant difference in the incidence of TOLAC success or failure among the three groups (all P>0.05). There was no uterine rupture in all groups. (4) The main factors affecting TOLAC score of pregnant women in the three groups included natural labor, estimated weight of the fetus at this time, Bishop score of the cervix at admission and gestational age, and the scores of the above indexes in 10-15 group were significantly higher than those in 0-6 group and 7-9 group (all P<0.05). Conclusions: TOLAC scoring scale has more accurate evaluation ability for VBAC, which could improve the success rate of TOLAC and maternal and child safety. The score of 0-6 is not recommended for vaginal trial labor, the score of 7-9 is recommended for vaginal trial labor, and the score of 10-15 is strongly recommended for vaginal trial labor.

First-trimester uterine rupture: a case report and systematic review of the literature

OBJECTIVE

This study aimed to present a case of first-trimester uterine rupture and perform a systematic review to identify common presentations, risk factors, and management strategies.

DATA SOURCES

Searches were performed in PubMed, Ovid, and Scopus using a combination of key words related to "uterine rupture," "first trimester," and "early pregnancy" from database inception to September 30, 2020.

STUDY ELIGIBILITY CRITERIA

English language descriptions of uterine rupture at ≤14 weeks of gestation were included, and cases involving pregnancy termination and ectopic pregnancy were excluded.

METHODS

Outcomes for the systematic review included maternal demographics, description of uterine rupture, and specifics of uterine rupture diagnosis and management. Data were extracted to custom-made reporting forms. Median values were calculated for continuous variables, and percentages were calculated for categorical variables. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for case reports and case series.

RESULTS

Overall, 61 cases of first-trimester uterine rupture were identified, including our novel case. First-trimester uterine ruptures occurred at a median gestation of 11 weeks. Most patients (59/61 [97%]) had abdominal pain as a presenting symptom, and previous uterine surgery was prevalent (44/61 [62%]), usually low transverse cesarean delivery (32/61 [52%]). The diagnosis of uterine rupture was generally made after surgical exploration (37/61 [61%]), with rupture noted in the fundus in 26 of 61 cases (43%) and in the lower segment in 27 of 61 cases (44%). Primary repair of the defect was possible in 40 of 61 cases (66%), whereas hysterectomy was performed in 18 of 61 cases (30%). Continuing pregnancy was possible in 4 of 61 cases (7%).

CONCLUSION

Uterine rupture is an uncommon occurrence but should be considered in patients with an acute abdomen in early pregnancy, especially in women with previous uterine surgery. Surgical exploration is typically needed to confirm the diagnosis and for management. Hysterectomy is not always necessary; primary uterine repair is sufficient in more than two-thirds of the cases to achieve hemostasis. Continuing pregnancy, although uncommon, is also possible.

[Uterine rupture in a patient with a cesarean scar pregnancy]

Caesarean scar pregnancy is a rare form of ectopic pregnancy, but it is increasingly common due to the increasing number of caesarean sections and advances in medical imaging. There are two types of cesarean scar pregnancy depending on the depth of the implantation : endogenous type I and exogenous type II. In the case of a pregnancy resulting from a type II caesarean scar, the main complication is uterine rupture, which could be life-threatening for the patient. Early diagnosis and treatment are therefore essential for the woman. We report the case of a patient in early pregnancy with a history of cesarean section who presented with severe pelvic pain due to uterine rupture.

Posterior uterine rupture in early first trimester

Uterine rupture can be associated with severe maternal and neonatal morbidity and mortality. It should be considered as a differential diagnosis in all pregnant women who present with acute abdomen, haemoperitoneum and have specific risk factors, even during the first trimester. This is a case report of a 25-year-old woman who presented to emergency department with abdominal pain and vaginal bleeding at approximately 6-8 weeks gestation. She developed an acute surgical abdomen and required urgent surgical management. Despite intervention, she had massive haemorrhage, disseminate intravascular coagulation, admission to intensive care unit and prolonged hospital stay as complications. Posterior uterine wall rupture while rare, must be considered as a differential diagnosis as early intervention is crucial to prevent bad outcomes.

Angular Pregnancy: An Eccentric Implantation Within Uterine Cavity

Angular ectopic is a rare form of ectopic pregnancy which is diagnosed as intrauterine pregnancy on ultrasound but may rupture in second trimester leading to maternal mortality. We present a case of a 32-year-old primigravida who presented at 18 weeks gestation to the emergency department of national hospital Lahore with complaint of dizziness, sweating and epigastric pain for one hour. She had an episode of diarrhoea and vomiting at hospital followed by rapidly increased abdominal distension and signs of hypovolemic shock. Urgent ultrasound suggested rupture of posterior uterine wall and massive hemoperitoneum. An urgent laparotomy was done. Uterus was perforated by pregnancy posteriorly. baby was inside the sac and alive. But died soon after birth. Uterus was repaired in two layers. Stepwise devascularization of uterus was done due to continuous bleeding. 6 units whole blood 6 FFP were transfused. The abnormal location of this pregnancy makes it antenatal diagnosis difficult. A high index of suspicion is needed in pregnant women presenting in shock even when intrauterine location of pregnancy is diagnosed in first trimester.

Recurrent uterine rupture in third trimester of pregnancy

We report a case of recurrent upper segment uterine rupture in a 31-year-old woman at 32+5/40 weeks of gestation. She had fundal uterine rupture 3 years ago in her first pregnancy at 40 weeks of gestation. There was no history of uterine malformation or prior uterine surgery. However, we noted that she had had three laparoscopic procedures for endometriosis treatment. She was scheduled to have an elective repeat caesarean section at 34+6/40 weeks of gestation in the index pregnancy. Unfortunately, she presented at 32+5/40 weeks with features of acute abdomen and signs of fetal distress. She had a category 1 caesarean section and was found to have fundal uterine rupture at the same site. She had a smooth uneventful recovery following a timely intervention and discharged home on day 5 postoperatively in a good condition with her baby girl.

Spontaneous rupture of unscarred uterus in the third trimester after in vitro fertilization-embryo transfer because of bilateral salpingectomy: A case report

RATIONALE

Rupture of an unscarred uterus after in vitro fertilization-embryo transfer (IVF-ET) in a primiparous woman is rare. Assisted reproductive technology (ART)-induced rupture of an unscarred uterus is usually attributable to increased dizygotic twinning rates. Salpingectomy can result in cornual scarring and increase the risk of uterine rupture as well as the mortality rate in a subsequent ectopic pregnancy. Here, we present the first reported case of a spontaneous, third-trimester, uterine rupture in a primiparous woman after IVF-ET due to a history of bilateral salpingectomy because of bilateral oviduct and ovarian cysts; the patient did not have an ectopic pregnancy or any cornual or other uterine scarring during this pregnancy after IVF-ET.

PATIENT CONCERNS

A 24-year-old woman with a history of IVF-ET and bilateral salpingectomy was admitted to our hospital with unexplained acute upper abdominal pain during the third trimester.

DIAGNOSIS

The fetal heart rate was abnormal. Abdominal ultrasonography was negative. Computed tomography revealed a small amount of abdominal and pericardial effusion. Laboratory tests revealed increased white blood cells. A diagnosis of pregnancy complicated by acute abdomen was considered. Emergent exploratory laparotomy revealed a uterine rupture at the right fundus adjacent to the right cornual area.

INTERVENTIONS

The patient was successfully managed with simultaneous exploratory laparotomy and lower-segment cesarean section. The rupture site was repaired.

OUTCOMES

Two live infants were uneventfully delivered. Follow-up assessments of the mother and the female baby on the 42nd postpartum day yielded normal results. The male infant was diagnosed with left hydronephrosis and required an operation.

LESSONS

We conclude that the ART-associated increase in dizygotic twinning rates may be a neglected risk factor for spontaneous rupture of the unscarred uterus, especially in patients who have undergone salpingectomy. Uterine rupture should be considered in a patient with multiple pregnancy following IVF-ET who presents with acute abdominal pain and abnormal fetal heart rate. Timely exploratory laparotomy is the key to a good prognosis.

Surgical emergencies in pregnancy in the era of modern diagnostics and treatment

Pregnancy can be complicated with different surgical emergencies which may potentially endanger the mother as well as foetus. In the modern era of advanced diagnostics and treatments, neither of them in response to a surgical emergency in a pregnant woman should be delayed. Appropriate early intervention is essential to decrease the morbidity and mortality. Following article encompasses common surgical emergencies that can arise in a pregnant woman and tries to suggest the approach that may be taken to reduce the burden of morbidity and mortality.

Automated early detection of obstetric complications: theoretic and methodologic considerations

Compared with adults who are admitted to general medical-surgical wards, women who are admitted to labor and delivery services are at much lower risk of experiencing unexpected critical illness. Nonetheless, critical illness and other complications that put either the mother or fetus at risk do occur. One potential approach to prevention is to use automated early warning systems, such as those used for nonpregnant adults. Predictive models that use data extracted in real time from electronic records constitute the cornerstone of such systems. This article addresses several issues that are involved in the development of such predictive models: specification of temporal characteristics, choice of denominator, selection of outcomes for model calibration, potential uses of existing adult severity of illness scores, approaches to data processing, statistical considerations, validation, and options for instantiation. These have not been addressed explicitly in the obstetrics literature, which has focused on the use of manually assigned scores. In addition, this article provides some results from work in progress to develop 2 obstetric predictive models with the use of data from 262,071 women who were admitted to a labor and delivery service at 15 Kaiser Permanente Northern California hospitals between 2010 and 2017.

Ruptured caesarean scar ectopic pregnancy: a diagnostic dilemma in a resource-limited setting

BACKGROUND

Caesarean scar pregnancy (CSP) remains a very rare form of ectopic pregnancy associated with serious life threatening obstetric complications and even death in case of late diagnosis and treatment.

CASE PRESENTATION

We report a case of a ruptured caesarean scar pregnancy in a 29 year-old gravida 5, para 3 with a past obstetric history of two consecutive caesarean sections done 9 and 5 years ago respectively. The patient presented with intermittent lower abdominal pains on a 20 weeks gestation associated with mild epigastralgia and 2 previous episodes of mild pervaginal bleeding (2 and 1 months ago respectively before consultation) managed with injectable progesterone. Her evolution 4 h later was marked by an increase in the intensity of the abdominal pain, an unmeasurable blood pressure and a feeble pulse. Immediate paracentesis revealed 10 cc of fresh non coagulating blood. The diagnosis of ruptured ectopic pregnancy with abundant hemoperitoneum was considered and an emergency laparotomy with fluid and blood resuscitation was carried out. A midline laparotomy revealed a ruptured caesarean scar ectopic pregnancy with an abundant hemoperitoneum. Careful resection of the placenta and repair of the ruptured isthmic region of the uterus was carried out. Recovery after surgery was without complications and the patient was discharged on the 6th day following surgery.

CONCLUSION

Caesarean scar pregnancy remains a very rare obstetric condition. Late diagnosis of this condition can be associated with serious life threatening obstetric complications. The rarity of the condition warrants a high index of suspicion among clinicians.

[Obstetrics]

During the past year, we have renewed interest in old well-known problems. New studies and guidelines have been issued about lung maturation in cases of preterm delivery after 37 weeks of gestation. Short term benefits have been proven but the number of cases needed to treat to prevent one case of respiratory complications is high and with possible neurological long-term effects. Also, several studies have shown the benefits of including the ultrasound measurement of the inferior segment of the uterus in order to attempt vaginal delivery after caesarean section with the lowest risk for uterine rupture, while others studies have shown the best procedure to close the uterus during cesarean section. And finally, we will discuss about an old friend: aspirin to reduce the risk of pre-eclampsia.

[Spontaneous rupture of the uterine artery in connection with pregnancy]

OBJECTIVE

To present two cases of spontaneous uterine artery rupture in connection with pregnancy, accompanied by life endangering bleeding. In the first case we talk about a thirty-three years old primigravida nullipara in the 20th week of pregnancy. In the second case there is a woman, who gave spontaneous birth in the 36th week of pregnancy.

DESIGN

Case report.

SETTING

Department of Obstetrics and Gynecology, Pardubice Hospital.

METHODS

Own observation.

CONCLUSION

Spontaneous rupture of the uterine artery in connection with pregnancy is a rare complication that can be fatal for mother and fetus. Clinical symptoms are often nonspecific, diagnostics is difficult, and diagnosis is often made during the surgery. It is necessary to include this rare complication in the differential diagnosis in pregnant women with abdominal pain and haemoperitoneum of unknown etiology and in postpartal women with an unknown source of bleeding.

Considerations of Epidural Analgesia in a Patient With Suspected Uterine Rupture

The practice of epidural analgesia in laboring women began to emerge in the 1970s. It is now a common method of pain relief for patients in labor and is used by 63% of women in the hospital setting. The patient who has had a previous cesarean delivery can benefit from having an epidural anesthetic placed early to expedite an emergency, such as a uterine rupture, if necessary. At one time there was a concern for placing an epidural anesthetic in laboring women who had a previous cesarean delivery. It was feared that the epidural anesthesia would mask abdominal pain that may present with a ruptured uterus and delay diagnosis. This worry was quickly dispelled with literature that strongly suggested that epidural analgesia did not disguise the signs or delay diagnosis of uterine rupture. The case presented is one in which pain of a uterine rupture was experienced with a functioning epidural catheter in situ, and successful anesthetic management.

[Asymptomatic spontaneous rupture of the uterus without previous sectio]

Rupture of the uterus is rare but catastrophic. Rupture often results in fetal bradycardia, abdominal pain, haemodynamic changes and vaginal bleeding. A 36-year-old healthy woman, gravida 3, para 1, went into spontaneous labour at gestation age 39 + 4, and at orificium 7 cm she received epidural analgesia. Following the epidural, the fetal heartbeat could not be registered by external cardiotocography, and caput could not be palpated. Spontaneous birth was attempted, but a caesarean section was necessary. The baby was found in the abdomen. Uterus was successfully contracted, thus preventing fatal bleeding. Asymptomatic rupture of the unscarred uterus is rare and difficult to diagnose.

Spontaneous uterine rupture at 28 weeks: A case report

Spontaneous Uterine rupture is associated with massive intra-peritoneal bleed which can be fatal if not recognized. We report a case of 32 year old multigravida at 28 weeks of gestation with history of liver cysts, previous caesarean and uterine curettage, who presented with acute abdominal pain and tenderness; ultrasound revealed placenta percreta. CT abdomen showed haemoperitoneum. The patient underwent emergency caesarean hysterectomy due to uterine rupture at the cornual site.

Congenital Uterine Anomalies and Uterine Rupture

Congenital uterine anomalies are more common than previously recognized. While many women will have no symptoms or problems, some women with congenital uterine anomalies have increased risks of adverse outcomes during pregnancy. This article presents a case study of a woman with a congenital uterine anomaly leading to spontaneous rupture of her unscarred uterus remote from term. The most common types of congenital uterine anomalies and their associated reproductive risks are reviewed. Evaluation of congenital uterine anomalies and management alternatives are discussed.

Can Intrapartum Cardiotocography Predict Uterine Rupture among Women with Prior Caesarean Delivery?: A Population Based Case-Control Study

OBJECTIVE

To compare cardiotocographic abnormalities recorded during labour in women with prior caesarean delivery (CD) and complete uterine rupture with those recorded in controls with prior CD without uterine rupture.

STUDY DESIGN

Women with complete uterine rupture during labour between 1997 and 2008 were identified in the Danish Medical Birth Registry (n = 181). Cases were validated by review of medical records and 53 cases with prior CD, trial of labour, available cardiotocogram (CTG) and complete uterine rupture were included and compared with 43 controls with prior CD, trial of labour and available CTG. The CTG tracings were assessed by 19 independent experts divided into groups of three different experts for each tracing. The assessors were blinded to group, outcome and clinical data. They analyzed occurrence of defined abnormalities and classified the traces as normal, suspicious, pathological or pre-terminal according to international guidelines (FIGO).

RESULTS

A pathological CTG during the first stage of labour was present in 77% of cases and in 53% of the controls (OR 2.58 [CI: 0.96-6.94] P = 0.066). Fetal tachycardia was more frequent in cases with uterine rupture (OR 2.50 [CI: 1.0-6.26] P = 0.053). Significantly more cases showed more than 10 severe variable decelerations compared with controls (OR 22 [CI: 1.54-314.2] P = 0.022). Uterine tachysystole was not correlated with the presence of uterine rupture.

CONCLUSION

A pathological cardiotocogram should lead to particular attention on threatening uterine rupture but cannot be considered a strong predictor as it is common in all women with trial of labour after caesarean delivery.

[Adrenocortical oncocytoma presenting as Cushing´s syndrome in pregnancy with spontaneous postpartum uterine rupture]

OBJECTIVE

The description of rare case of the Cushings syndrome in pregnancy resulting in the spontaneous rupture of uterus.

DESIGNS

A case report.

SETTING

Department of Gynecology and Obstetrics, 1st Medical Faculty of Charles University and Hospital Na Bulovce.

CASE REPORT

The authors report the case of a 33 year old woman, who was admitted to the clinic in 30th week of pregnancy for elevated blood pressure and hypokalemia. Arterial hypertension was corrected with the combination of Vasocardin and Dopegyt. In 36th week of pregnancy the patient was admitted to the hospital with premature rupture of membranes. In less than sixteen hours the patient spontaneously gave birth to a healthy girl. Subsequently the patient suffered from abdominal pain. CT scan showed haemoperitoneum and a right adrenal mass and the surgical revision was performed. During the surgery uterine rupture was identified and the patient uderwent abdominal hysterectomy. Based on the endocrinological examination the diagnosis of Cushings syndrome was made. Three months after the delivery she underwent laparoscopic right adrenalectomy. Histological examination revealed adrenocortical oncocytoma.

CONCLUSION

Cushings syndrome is rare in pregnancy and misdiagnosis is common. Symptoms mimic pregnancy complications. The disease is often diagnosed with delay even after delivery. The sonography and magnetic resonance are dominant imaging methods. Laboratory diagnosis is difficult due to pregnancy related changes. In spite of rarity of Cushings syndrome in pregnancy we should think about it in terms of the differential diagnosis of hypertension, diabetes, dysbalance of mineralogram and typical cushingoid habitus.

[Life-threatening extrauterine pregnancy after in vitro fertilization and bilateral salpingectomy]

A woman with a history of bilateral salpingectomy achieved pregnancy after in vitro fertilization. At the gestational age of six weeks she experienced fatigue, haematemesis and abdominal pain. She was hospitalized on suspicion of a peptic ulcer. Several physicians rejected the possibility of an ectopic pregnancy due to the history of salpingectomy. The patient had intraabdominal bleeding and went through emergency surgery because of a ruptured interstitial pregnancy. The purpose of this case report is to recall the risk of interstitial pregnancy in pregnant women with a history of salpingectomy.

A novel case of an adenomyosis-related uterine rupture in pregnancy

To date, few cases of uterine rupture related to adenomyosis have been reported. The current case report briefly describes a novel case of an adenomyosis related uterine rupture, while focusing on few symptoms that this kind of uterine rupture may have. Due to increasing rate of adenomyosis in Western countries, practicing obstetricians should carefully take in account silent uterine rupture related to adenomyosis.

Uterine rupture at 26 weeks of pregnancy following laparoscopic salpingectomy with resection of the interstitial portion: a case report

Uterine rupture in pregnancy can occur in patients with a history of uterine surgery such as myomectomy and Cesarean section. Here, we report a case of spontaneous uterine rupture that occurred in the early third trimester in a pregnant woman who had previously undergone laparoscopic removal of the right fallopian tube and interstitial portion for treatment of interstitial pregnancy. The patient presented with sudden onset of abdominal pain at 26 weeks of gestation. Detailed ultrasonography and magnetic resonance imaging led to diagnosis of uterine rupture. In emergency laparotomy, the fetus was delivered by Cesarean section, the placenta and membranes were removed, and the uterus was preserved with closure of the rupture and wound. This case highlights the importance of close follow-up of a pregnant patient who has previously had a uterine incision. The case also raises the question of whether the prevalence of uterine rupture may increase as more patients are treated with laparoscopic surgery of the uterus.

[Clinical study on 67 cases with uterine rupture]

OBJECTIVE

To investigate the incidence, etiology, diagnosis, treatment and outcome of uterus rupture.

METHODS

From January 1999 to May 2013, clinical data of 67 cases with uterine rupture in Woman's Hospital, School of Medicine, Zhejiang University were studied retrospectively.

RESULTS

A total of 67 cases of uterine rupture with 21(+2)-39(+2) gestational weeks out of 128 599 deliveries were recorded giving an incidence of uterine rupture was 0.052 1% (67/128 599) . Cesarean scar rupture were found in 59 cases (88%, 59/67) and noncesarean scar rupture were found in 8 cases (12%, 8/67). The causes of uterine rupture include 60 cases of scar uterus (59 cesarean scar cases and 1 myomyectomy scar case), 2 cases of assisted delivery operation trauma, 2 cases of malformed uterus, 3 cases of unknown causes (all with artificial abortion history).Non obstructive dystocia and improper oxytocin use were found to be related with uterine rupture.Fifty-two cases of cesarean scar spontaneous incomplete rupture were found and repaired during repeated cesarean delivery without maternal and fetal complications. The remaining 15 cases need emergency rescue operation for fetal distress or dead fetus, severe acute abdomen, prepartum or postpartum vaginal bleeding even maternal hypovolemia; 6/15 uterine rupture cases were diagnosed with the history, clinical symptoms and signs, 3/15 cases with ultrasonic found dead fetus in the peritoneal cavity before exploratory laparotomy and 6 cases were diagnosed just during laparotomy.Hysterectomy was done in 10/15 cases and uterine repair in 5/15 cases; there was no maternal death and 12 perinatal fetal death (5 cases of mid-late pregnancy termination for deformed fetus) of the 15 uterine rupture cases.One case with hysterectomy was complicated with stress pancreatitis and dysfunction of liver and kidney and discharged 20 days after operation, the remaining 14 cases were discharged 5-7 days postpartum.One case with repaired malformed uterus got pregnancy 4 years later and delivered a 2 000 g healthy baby by cesarean section at gestational age of 33(+4) weeks.

CONCLUSION

Uterine scar caused by caesarean section or other operations became the leading cause of uterine rupture, assisted delivery operations, history of intrauterine manipulation and uterine malformations were the predisposing risk factors of uterine rupture.

Adnexal sonographic findings in ectopic pregnancy and their correlation with tubal rupture and human chorionic gonadotropin levels

OBJECTIVES

To determine whether the distribution of transvaginal sonographic findings of ectopic pregnancy has changed since the studies done 20 years ago and to explore the correlation of tubal rupture with transvaginal sonographic findings and human chorionic gonadotropin (hCG) levels.

METHODS

Patients with ectopic pregnancy who underwent transvaginal sonography before treatment were included. Sonograms and medical records were retrospectively reviewed. The presence of a tubal ring, the presence of a yolk sac, embryonic cardiac activity, the degree of vascularity on color Doppler imaging, hCG levels, and results of surgery were recorded.

RESULTS

Our study included 231 ectopic pregnancies. A positive sonographic adnexal finding was present in 219 cases (94.8%): adnexal mass in 218 (94.4%) and a moderate-to-large amount of free fluid in 84 (36.4%). The adnexal masses were graded as follows: 1, nonspecific mass (125 cases [54.1% of total]); 2, tubal ring without a yolk sac or embryo (57 [24.7%]); 3, yolk sac but no embryonic heartbeat (19 [8.3%]); and 4, embryo with cardiac activity (17 [7.4%]). The mean hCG level increased as the grade ascended from 1 to 4. Thirty-six patients had tubal rupture at surgery within 24 hours of the sonogram. A moderate-to-large amount of free fluid was significantly associated with tubal rupture (P < .05) but had low sensitivity, specificity, and positive predictive value for rupture. Other sonographic findings and hCG levels were not significantly related to tubal rupture.

CONCLUSIONS

Transvaginal sonography showed an adnexal abnormality in nearly 95% of our patients with ectopic pregnancy, most commonly a nonspecific adnexal mass. Embryonic cardiac activity was seen in fewer than 10%. Neither sonographic findings nor hCG levels were useful predictors of tubal rupture.

A case of uterine rupture in mid-trimester spontaneous abortion: a complication of gemeprost vaginal administration

The only prostaglandin analogue licensed in Italy for induction of labour in spontaneous and therapeutic abortion is gemeprost. The authors report a case of spontaneous uterine rupture of a scarred uterus, for previous caesarean sections, in a woman at 20 weeks of gestation with a diagnosis of spontaneous abortion. She received a pessary of gemeprost every three hours. After the fifth pessary, she complained of severe pain. At the ultrasound examination, uterine cavity appeared empty and the dead fetus was dislocated in the abdomen. Emergency laparotomy was performed and uterine tear was repaired. To induce labour for fetal demise or therapeutic abortion in second trimester in women with scarred uterus, the authors decided to lengthen the time between administrations of pessary from four to five hours depending on patient's symptoms. However the appropriate drug regimen has still to be found and more data are necessary.

[A pregnant woman with a painful abdominal retraction]

A 35-year old woman, gravida 2, para 1, came to our hospital with abdominal pain and a retraction of her abdomen, which appeared during her spontaneous contractions at 40 weeks and 5 days of pregnancy. She had a medical history of caesarean section for Frank breech presentation. This clinical presentation was suggestive for uterine rupture, which was confirmed during caesarean section.

[Incarcerated uterus in pregnancy - pitfalls of diagnosis, clinical course and therapy: two case reports]

OBJECTIVE

Analysis of two cases of incarcerated uterus during pregnancy.

DESIGN

Two case reports.

SETTING

Department of Gynecology and Obstetrics, Masaryk University, University Hospital Brno.

METHODS AND RESULTS

In two cases of incarcerated uterus, which were resolved on Department of Gynaecology and Obstetrics, University Hospital Brno is shown a different clinical course, leading to the detection and solutions at different gestational weeks. The first case was detected in 31st week of pregnancy and was characterized by nearly asymptomatic course in a pregnant woman with a scar in the lower uterine segment after a previous caesarean section. The delivery was scheduled for the end of the 36th week of pregnancy by iterative caesarean section. The second case was detected on the 27th week of pregnancy due to significant subjective difficulties of pregnant woman that impressed as acute event of abdomen. Despite all attempts at conservative therapy was necessary to terminate the pregnancy by caesarean section at 28 week of pregnancy due to the high risk of uterine rupture.

CONCLUSION

Incarcerated uterus is a rare complication of pregnancy. Diagnostics complains varied clinical picture of the nonspecific subjective difficulties. Missed diagnosis can lead to a number of serious obstetric complications. In case of failure of conservative therapy and progression of difficulties is necessary to think about the real risk of uterine rupture. Before performing a caesarean section is essential knowledge of the mutual position of the lower uterine segment, urinary bladder and cervix.

Placenta percreta and uterine rupture at 16 weeks

Placenta percreta is a complication of pregnancy with significant morbidity and mortality rates. Spontaneous uterine rupture in early pregnancy due to placenta percreta is rare. We report a case of this life-threatening complication occurring at the sixteenth week of gestation. The patient presented with signs of shock, acute abdomen, and evidence of hemoperitoneum. The pregnancy was viable with a normal ultrasound appearance that created some confusion and there was a dilemma in the diagnosis of this case. Various obstetric and surgical causes were taken into consideration. The patient was taken to the operating room immediately for exploratory laparotomy. She was found to have fundal uterine rupture, which was managed by uterine repair. This patient had prior cesarean section and dilatation and curettage; factors well known to predispose for placenta percreta. Here, we emphasize the importance of a fast decision and surgical intervention to save a patient's life in cases of uterine rupture.

Incidence and management of rupture uterus in obstructed labour

BACKGROUND

Obstructed labour with ruptured uterus is a serious obstetrical complication with a high incidence of maternal and foetal morbidity and mortality. This study was conducted to find out the incidence of uterine rupture particularly in the patients of obstructed labour (OL), foeto-maternal outcome of such patients, and its management.

METHODS

This two year descriptive study was conducted in the Department of Obstetrics and Gynaecology Unit-I, at Muhammad Medical College Hospital from 1st January 2007 to 31st December 2008, on 40 diagnosed cases of OL. Patients were admitted through Casualty or were admitted in ward. Patients with previous caesarean section and myomectomy were excluded.

RESULTS

Ruptured uterus was found in 8 out of 40 patients of obstructed labour, they were relatively elder and grand-multiparous. Mean age of the patients was 36.5 years, while parity ranged between 5 and 12. Only one (12.5%) patient was primigravida with mean gestational age of 39.15 weeks. Seven (87.5%) patients had abdominal pain and tenderness, 5 (62.5%) vaginal bleeding, and 2 (25%) had shock. All cases were immediately managed with fluid replacement, blood transfusion and surgery. Six (75%) cases were diagnosed as ruptured uterus on clinical features while 2 (25%) with incomplete rupture were diagnosed on caesarean section for obstructed labour. Foetal mortality rate was high (7, 87.5%); 5 (62.5%) were fresh stillbirth and 2 (12.5%) died in nursery. Only 1 (12.5%) baby survived. There was 1 maternal death due to puerperal sepsis.

CONCLUSION

The incidence of rupture uterus in obstructed labour was 20%. Immediate intervention is important factor for successful management of uterine rupture.

Silent uterine rupture of scarred uterus--an unusual presentation as amniocele

Obstetricians should be aware of the possibility of silent rupture of scarred uterus. Ultrasound has an important role in the diagnosis of silent uterine rupture. A case of silent uterine rupture with foetal demise, that remained undiagnosed for many weeks, is described.

Case records of the Massachusetts General Hospital: Case 34-2012: a 27-year-old woman in Ethiopia with severe pain, bleeding, and shock during labor

A 27-year-old woman was admitted to a hospital in Ethiopia because of severe abdominal pain during labor, with cessation of contractions. She had been in labor at home, pushing for 24 hours. On arrival at the hospital 3 hours later, she was in shock. A procedure was performed.
