Spontaneous uterine rupture in the first trimester: a case report

A cesarean section scar dehiscence during the first trimester of an intrauterine pregnancy: a rare case report and literature review

Uterine rupture is specified as a complete laceration of the uterine wall, including its serosa, leading to a connection between the endometrial and peritoneal chambers. It can occur in any stage of pregnancy and is considered a severe and perhaps fatal complication. A 35-year-old woman at 9 weeks of gestation with a medical history of five prior cesarean sections presented with lower abdominal pain that had lasted for 5 hr. We detected small amounts of free fluid in the Douglas pouch using ultrasound. Subsequently, a laparotomy revealed a cesarean scar dehiscence from a non-cesarean scar pregnancy. Patients who experience a uterine rupture may have vague symptoms, severe abdominal discomfort, abnormal uterine bleeding, and severe hemorrhagic shock, depending on their gestational age. Ultrasound imaging can be used to diagnose this fatal condition in addition to laparoscopy to immediately identify and treat the issue in urgent cases.

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.

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

Importance

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

Objective

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

Evidence Acquisition

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

Results

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

Conclusions and relevance

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

Surgical uterus-preserving therapy after uterine rupture and haemorrhage due to placenta percreta in the first trimester following embolisation of the uterine arteries and B-Lynch suture in a previous pregnancy

A woman in her early 30s in the 11 2/7 week of pregnancy was admitted with severe abdominal pain and emesis. One year prior, the patient had undergone hysteroscopic adhesiolysis to treat Asherman syndrome resulting from a prior pregnancy. Examination of the patient revealed a haemoperitoneum and an intact intrauterine pregnancy. Laparoscopic adhesiolysis and haemostasis was performed and the patient was transferred to the intensive care unit. Subsequent examination due to persistent abdominal pain revealed an occult iatrogenic perforation of the uterus and placenta percreta with spontaneous uterine rupture. Although treatment for placenta percreta has generally been hysterectomy, in this case, the rupture and perforation sites were resected, representing successful fertility preserving management for this oft-overlooked pregnancy complication.

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.

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.

Spontaneous unscarred uterine rupture in a primigravid patient at 11 weeks of gestation managed surgically: A rare case report

INTRODUCTION

Spontaneous rupture of the primigravid uterus is a rare but catastrophic obstetrical emergency. It usually occurs late in pregnancy or during labour, mainly in multiparous women. But, spontaneous unscarred uterine rupture in a primigravid patient that also in first trimester is very rare. There are only 12 papers in Pub Med database regarding spontaneous unscarred uterine rupture in primigravid in early pregnancy.

CASE PRESENTATION

A 23-year-old primigravid female at 11th week of pregnancy, with no significant medical or surgical history, presented with sudden onset of generalised abdominal pain for four hours with multiple episodes of vomiting. On physical examination, patient was pale, in haemorrhagic shock with diffuse abdominal tenderness. Ultrasonography showed extra uterine gestational sac with massive haemoperitoneum. Eventually, patient was subjected to emergency laparotomy after resuscitation.

CLINICAL DISCUSSION

Spontaneous rupture of unscarred gravid uterus is a catastrophic rare condition that can be missed leading to maternal and foetal mortality. There are no pathognomonic features indicating the condition therefore it should be differentiated from other causes of acute abdominal emergencies.

CONCLUSION

Spontaneous rupture of unscarred gravid uterus should be differentiated from other acute abdominal emergencies. Patient may land up in emergency department in the state of shock, emergency physicians should be aware of its symptoms or presentations.

Spontaneous uterine rupture during the first trimester of a partial molar pregnancy in a scar uterus: A rare case report

Introduction

Spontaneous uterine rupture in the first trimester is a redoubtable obstetric emergency that carries a high risk for both mother and fetus.

Cases presentation

We present the case of a spontaneous uterine rupture in a patient with a scarred uterus at 9 weeks' gestation treated by laparotomy in emergency obstetrical department of Ibn Rochd University Hospital of Casablanca; whose histological examination of the removed material found a partial mole.

Clinical discussion

Spontaneous uterine rupture in the first trimester is rare and usually occurs in a scarred or malformed uterus. Clinicians should consider this diagnosis in the presence of an acute abdominal pain in early pregnancy with or without first trimester metrorrhagia.

Conclusion

Since the rate of uterine surgeries is increasing, it is necessary to highlight the risk of uterine rupture occurring early in order to improve their management. Molar pregnancy is a factor of fragility of the uterine wall and uterine rupture must be suspected in any molar pregnancy associated with a hemoperitoneum.

•

Spontaneous uterine rupture in the first trimester is rare.

•

Diagnosis suspected in the presence of any acute abdominal pain in early pregnancy.

•

Uterine scarring is the main factor promoting early uterine rupture

UTERINE RUPTURE IN THIRD TRIMESTER OF PREGNANCY FOLLOWING CORNUAL RESECTION DUE TO ECTOPIC PREGNANCY

Uterine rupture during pregnancy is a critical obstetric complication associated with maternal and fetal mortality and morbidity. The risk is increased in patients with a history of previous uterine surgery including cesarean section, myomectomy, salpingectomy, as well as uterine and placental anomalies and polyhydramnios. It can also occur spontaneously. We present a case of uterine rupture in the early third trimester in a woman who had undergone previous laparoscopic removal of the left fallopian tube due to sactosalpinx and laparotomic removal of left uterine horn due to ectopic pregnancy.

Second trimester rupture uterus, unusual presentation

Introduction

Spontaneous uterine rupture before onset of labour is extremely rare. This is even more so in the second trimester of pregnancy, in nulliparous women and in the absence of myometrial surgery. The initial presentation of this potentially catastrophic event may be non-specific, with upper or lower abdominal discomfort, vague gastrointestinal or urinary symptoms preceding rapid deterioration.

Discussion

This case report demonstrates that a high index of suspicion, rapid diagnosis aided by imaging modalities and immediate surgical intervention are crucial steps in successful management. A postulated etiology in our patient is that of an upper scar from a previous uterine curettage with abnormal placentation predisposing to spontaneous rupture.

Presentation of case

A case of spontaneous uterine rupture at 16 week's gestation in a multiparous, 32 year old patient with no history of myometrial surgery. She had presented with lower abdominal discomfort, progressing to severe pain with hypotension and tachycardia. An urgent ultrasound pelvis showed a live fetus, free intra-peritoneal fluid with blood clots. An emergency laparotomy performed revealed 2 L of hemoperitoneum, with the fetus intact in the amniotic sac. The uterine fundal rupture was successfully repaired.

Conclusion

Despite the gestation, in women presenting with symptoms and signs suggestive of acute abdomen and hemodynamic instability, prompt resuscitation must be instituted, and a high index of suspicion for rupture must be suspected.

Spontaneous unscarred uterine rupture and surgical repair at 11 weeks of gestation in a twin pregnancy

A uterine rupture may result in a massive hemoperitoneum, which can be fatal to both the fetus and mother. Most uterine ruptures during pregnancy occur within a scarred uterus, rarely occurring in an unscarred uterus. Here, we report a very rare case of spontaneous rupture in an unscarred uterus at 11 weeks of gestation of a twin pregnancy and its surgical repair. A 37-year-old nulliparous infertile woman became pregnant with twins after artificial insemination and gonadotropin therapy. She underwent emergency surgery at 11 weeks of gestation due to an acute abdomen caused by massive hemoperitoneum. Upon laparotomy, one fetus with placenta was extruded into the abdominal cavity through a 3-cm myometrium rupture on the left posterior wall of the uterus. After surgical repair of the rupture site, the remaining fetus was alive and was successfully delivered by cesarean section at 34 weeks of gestation.

First Trimester Uterine Rupture: A Case Report and Literature Review

The aim is to report a case of spontaneous uterine rupture in the first trimester of pregnancy and to review the literature on the topic.

METHODS

A literature search was performed using PubMed and Scopus. Relevant English articles were identified without any time or study limitations. The data were aggregated, and a summary statistic was calculated.

RESULTS

A 35-year-old gravida 5, para 2 was admitted at our department because of fainting and abdominal pain. The woman had a first-trimester twin pregnancy and a history of two previous cesarean sections (CSs). Suspecting a uterine rupture, an emergency laparotomy was performed. The two sacs were completely removed, and the uterine rupture site was closed with a double-layer suture. The patient was discharged from hospital four days later in good condition. On the basis of this experience, a total of 76 case reports were extracted from PubMed and included in the review. Fifty-three patients out of 76 (69.74%) underwent previous surgery on the uterus. Most women (67.92%) had a CS, and in this group a cesarean scar pregnancy (CSP) or a placenta accreta spectrum (PAS) disorder was found to be the etiology in 77.78% of cases. Furthermore, 35.85% of the women had hysterectomy after uterine rupture. Twenty-three patients out of 76 (30.26%) had an unscarred uterus. Of this group, most women presented a uterine anomaly (43.48%). Moreover, 17.39% of these women had a hysterectomy.

CONCLUSION

According to the literature, the current pandemic use of CS explains most cases of first-trimester uterine rupture.

Laparoscopic hysterectomy to manage uterine rupture due to placenta percreta in the first trimester: A case report

Placenta percreta causing uterine rupture is a rare complication of pregnancy. It is most commonly diagnosed after the second trimester and can lead to significant morbidity necessitating abdominal hysterectomy of a gravid or immediately postpartum uterus. We describe a patient who presented with abdominal pain at 13 weeks of gestation and was diagnosed with placenta percreta during laparoscopy for presumed appendicitis. Intraoperatively, placenta was seen perforating the uterine fundus and 1 l of hemoperitoneum was evacuated. However, the uterus was hemostatic and the patient was stable, so the procedure was terminated. The patient was then transferred to a tertiary care center, where she ultimately underwent an uncomplicated laparoscopic gravid hysterectomy. We conclude that placenta percreta can occur in the first trimester even in patients without traditional risk factors. In stable patients, it is appropriate to consider minimally invasive hysterectomy with utilization of specific techniques to minimize intraoperative blood loss.

•

Uterine rupture due to placenta percreta can present in the first trimester.

•

Minimally invasive laparoscopic hysterectomy can provide definitive treatment with decreased surgical morbidity and shorter convalescence.

•

Blood loss and allogenic transfusion can be minimized with appropriate hemostatic techniques and surgical planning.

Placenta Percreta and Uterine Rupture in the First Trimester of Pregnancy

Spontaneous uterine rupture in the first trimester of pregnancy is uncommon and difficult to diagnose. Although extremely rare, it is important to consider the occurrence of placenta percreta as differential diagnosis of acute hemorrhagic abdomen at the beginning of pregnancy. We describe below a case of uterine rupture in the first trimester of pregnancy related to placenta percreta.

Second-trimester uterine rupture: lessons learnt

Uterine rupture is a rare life-threatening complication. It mainly occurs in the third trimester of pregnancy and is rarely seen during the first or second trimesters. Our centre experienced three important cases of uterine rupture.

FIRST CASE

spontaneous uterine rupture at 14 weeks of pregnancy, which was diagnosed at autopsy. It was misled by the ultrasound finding of an intrauterine pregnancy, and searching for other non-gynaecological causes delayed the urgent obstetric surgical management.

SECOND CASE

ruptured uterus at 24 weeks following medical termination due to foetal anomaly. It was diagnosed only at laparotomy indicated for failed medical termination and chorioamnionitis. Third case: uterine rupture at 21 weeks of pregnancy in a patient with gastroenterology symptoms. In these reports, we have discussed the various risk factors, presentations, course of events and difficulties in diagnosing uterine rupture. The study concludes that the clinical presentation of uterine ruptures varies. It occurs regardless of gestational age. Ultrasound findings of intrauterine pregnancy with free fluid do not exclude uterine rupture or ectopic pregnancy. Searching for non-gynaecological causes in such clinical presentations might delay crucial surgical intervention, which leads to unnecessary morbidity, mortality or loss of obstetrics function.

Unforeseen consequences of the increasing rate of cesarean deliveries: early placenta accreta and cesarean scar pregnancy. A review

This review concentrates on 2 consequences of cesarean deliveries that may occur in a subsequent pregnancy. They are the pathologically adherent placenta and the cesarean scar pregnancy. We explored their clinical and diagnostic as well as therapeutic similarities. We reviewed the literature concerning the occurrence of early placenta accreta and cesarean section scar pregnancy. The review resulted in several conclusions: (1) the diagnosis of placenta accreta and cesarean scar pregnancy is difficult; (2) transvaginal ultrasound seems to be the best diagnostic tool to establish the diagnosis; (3) an early and correct diagnosis may prevent some of their complications; (4) curettage and systemic methotrexate therapy and embolization as single treatments should be avoided if possible; and (5) in the case of cesarean scar pregnancy, local methotrexate- and hysteroscopic-directed procedures had the lowest complication rates.

Placenta percreta-induced uterine rupture diagnosed by laparoscopy in the first trimester

Spontaneous uterine rupture is lethal in pregnant women. Placenta percreta-induced spontaneous uterine rupture in the first trimester is extremely rare and difficult to diagnose. A 35-year-old pregnant woman, with a history of 2 vaginal deliveries and 2 spontaneous abortions treated by dilatation and curettage, was admitted to the emergency department because of sudden severe abdominal pain; the gestational age as calculated by sonography was 14 weeks. Diagnostic laparoscopy was considered for surgical abdomen and fluid collection that was noted in sonography. During laparoscopy, uterine rupture with massive bleeding was detected; therefore, total abdominal hysterectomy was performed. The patient was discharged without any complications. Pathological analysis of the uterine specimen revealed placenta percreta to be the cause of the rupture. Uterine rupture should be considered in the differential diagnosis in all pregnant women who present with acute abdomen, show fluid collection in the peritoneal cavity. In addition, we recommend laparoscopy for the investigation of acute abdomen with unclear diagnosis in the first trimester of pregnancy.

Spontaneous intraperitoneal hemorrhage as the initial presentation of a gastrointestinal stromal tumor: a case report

BACKGROUND

Spontaneous hemoperitoneum is rare. The most common etiologies are gynecologic, splenic, and hepatic. Gastrointestinal stromal tumors (GISTs) are commonly associated with intraluminal bleeding, but rarely with spontaneous hemoperitoneum. We report a case of spontaneous hemoperitoneum caused by a gastric GIST.

CASE REPORT

A 54-year-old male presented with the acute onset of abdominal pain and a drop in hemoglobin. Subsequent evaluation, including a CT, MRI, and EUS, revealed a 1.2-cm mass along the greater curvature of the stomach and associated hemoperitoneum. The patient was taken electively to the operating room for laparoscopic removal of the mass. Pathology confirmed that it was a GIST.

CONCLUSION

GIST is a rare clinical entity that infrequently presents with spontaneous hemoperitoneum. Emergent treatment should be guided towards treating the spontaneous hemoperitoneum.

First trimester uterine rupture and scar pregnancy

Uterine rupture during the first trimester of pregnancy is an extremely rare, but life-threatening cause of intraperitoneal hemorrhage. Up to the knowledge of the authors all reports of first trimester uterine ruptures are related to scar dehiscences following previous cesarean sections or occurred in unscarred uteri of multiparous women. In cases of multiparity silent ruptures cannot be precluded, so that the uterus might be scarred during the following pregnancy. In early pregnancy of approximately 4-5 weeks, vaginal ultrasonography may clearly verify a scar pregnancy, but sonographical diagnostic findings may change with the pregnancy progress. In all cases of reported first trimester ruptures in pregnancies with previous cesarean sections or in pregnancies of multiparous women reported in literature, dating scans were performed too late for to preclude pregnancies in the scar. We postulate our hypotheses, that all first trimester uterine ruptures are caused by scar implantation of the trophoblast.

Misoprostol for treatment of early pregnancy failure in women with previous uterine surgery

OBJECTIVE

Misoprostol use in early pregnancy may incur a risk of uterine rupture in women with previous uterine surgery.

STUDY DESIGN

We analyzed 488 women who received misoprostol 800 microg vaginally in a study that evaluated medical and surgical management of early pregnancy failure. Subjects received a repeat misoprostol dose if expulsion was not confirmed 2 days after treatment. We compared efficacy, acceptability, and safety in subjects with a history (n = 78 women) or absence (n = 410 women) of uterine surgery, defined as cesarean delivery or myomectomy.

RESULTS

Expulsion rates after a single misoprostol dose (69% vs 72%; P = .64) and overall success at 30 days (82% vs 85%; P = .50) were comparable. Pain, bleeding, complications, and acceptability did not differ. No uterine ruptures occurred (95% CI, 0, 3.8%).

CONCLUSION

Misoprostol treatment for early pregnancy failure had similar success, acceptability, and complications in women with and without previous uterine surgery.
