RESUMO

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.

RESUMO

OBJETIVO: Reportar el manejo de un caso de rotura uterina asociado a percretismo placentario en el segundo trimestre de gestación; y realizar una revisión de la literatura acerca del diagnóstico y tratamiento de esta condición. PRESENTACIÓN DEL CASO: Paciente de 31 años con diagnóstico intraoperatorio de rotura uterina asociada a percretismo placentario a la semana 21 de gestación. Requirió manejo quirúrgico inmediato por abdomen agudo, presentando shock hipovolémico y muerte fetal in útero. Materiales y métodos: Se realizó una búsqueda de la literatura registrada en las bases de datos entre el año 1995 y 2017 y publicados en inglés y español. Se incluyeron los reportes de y series de caso y artículos de revisión, con relación al diagnóstico prenatal y tratamiento. RESULTADOS: La mayoría de los casos reportados de rotura uterina se describen en mujeres con rotura uterina por percretismo entre la semana 9 y 34 de gestación. El tratamiento es quirúrgico en la gran mayoría de casos y su abordaje dependerá de los hallazgos intraoperatorios y condiciones médicas asociadas. CONCLUSIÓN: El acretismo placentario presentado en etapas tempranas de la gestación es rara, sin embargo, se debe sospechar según hallazgos clínicos y paraclínicos. El manejo debe estar dirigido de acuerdo al grado de invasión placentaria y situación hemodinámica, la mayoría de las veces es quirúrgico y realizado por un equipo interdisciplinario.

OBJECTIVE: To report the management of a case of uterine rupture associated with placental percreta in the second trimester of pregnancy, and to make a review of the literature about the diagnosis and treatment of this condition. PRESENTACION OF THE CASE: A 31-year-old patient with intraoperative diagnosis of uterine rupture associated with placental percretism at week 21 of gestation, who required immediate surgical intervention for acute abdomen, which developed in a hypovolemic shock and fetal death in utero. MATERIALS AND METHODS: A Research was done of the literature registered in the databases between 1995 and 2017, and published in English and Spanish. We included case reports and case series and review articles, in relation to prenatal diagnosis and treatment. RESULTS: The majority of reported cases of uterine rupture that are found in women with this condition are due to percretism between week 9 and 34 of gestation. The treatment is surgical in the great number of cases, which procedure will follow depending on the intraoperative findings and associated medical conditions. CONCLUSION: Placental accreta presented at early stages of gestation is rare, however it should be taken into account while considering the clinical and paraclinical findings. The treatment must be directed accordingly to the degree of placental invasion and hemodynamic situation, although most of the time will lead to surgery performed by an interdisciplinary team.

RESUMO

PURPOSE: To evaluate the cases of uterine rupture and dehiscence of the uterine scar at a low-risk maternity and to point out possibilities for an improved approach to these complications. METHODS: A descriptive study was conducted at a 30-bed low-risk maternity hospital that provides care to users of the public health system. The investigation was carried out by searching for cases in the delivery room registry book and later reading the medical records in order to obtain the data. The information was inserted on a form previously elaborated for this study. Cases of uterine rupture and dehiscence of the uterine scar diagnosed from 1998 to 2012 were included, with the determination of incidence, aspects related to risk factors and diagnosis, association with the use of misoprostol and oxytocin, and the outcomes observed. RESULTS: A total of 39,206 deliveries were performed in this maternity during the study period, with 12 cases of uterine rupture and 16 cases of dehiscence of uterine scar being observed. The most relevant results were a high perinatal mortality associated with uterine rupture and the unsuccessful diagnosis of this complications. It was not possible to demonstrate an association with the use of misoprostol or oxytocin. CONCLUSION: The adverse outcomes of uterine rupture could be minimized if efforts were directed at improving the diagnostic performance of the assisting teams.

RESUMO

OBJETIVO: Analisar os casos de rotura uterina e deiscência de cicatriz uterina ocorridos em uma maternidade de baixo risco e apontar possibilidades de aprimoramento na abordagem dessas complicações. MÉTODOS: Foi realizado um estudo descritivo em uma maternidade de baixo risco com 30 leitos, que presta assistência às usuárias do sistema público de saúde. A investigação foi realizada por meio de busca dos casos em livros de registros de sala de parto e posterior leitura dos prontuários para coleta dos dados. As informações foram inseridas em formulário previamente elaborado para este estudo. Foram incluídos os casos de rotura uterina e deiscência de cicatriz uterina diagnosticados no período de 1998 a 2012, avaliados incidência, aspectos relacionados aos fatores de risco e diagnóstico, associação com o uso de misoprostol e ocitocina e desfechos observados. RESULTADOS: No período mencionado foram registrados 39.206 partos nessa instituição. A cesárea foi a conduta adotada em 10 mil partos, o que equivale a uma taxa de 25,5%. Foram identificados 12 casos de rotura uterina e 16 de deiscência de cicatriz uterina. Os resultados mais relevantes foram a alta mortalidade perinatal associada à rotura uterina e o insucesso no diagnóstico da complicação. Não foi possível demonstrar associações com o uso de misoprostol ou ocitocina. CONCLUSÃO: Os desfechos adversos da rotura uterina podem ser minimizados se esforços forem direcionados para melhorar o desempenho diagnóstico das equipes assistentes. .

RESUMO

BACKGROUND: Uterine rupture is a rare entity with an incidence of 0.07% and is a cause of perinatal mortality. Dehiscence of previous uterine scar is the most important cause, but other causes have been reported such as placenta percreta. Almost 80% of uterine ruptures are spontaneous and its complications lead to an elevated mortality rate for the mother and the fetus. CLINICAL CASES: Case 1. We present the case of a 28-year-old female with no previous relevant medical history. The patient was 20 weeks pregnant with a diagnosis of uterus didelphys (double uterus) with lower placental implantation with normal pregnancy evolution at the time. Evolution of her illness was with intense abdominal pain and transvaginal bleeding. Case 2. We present the case of a 20-year-old female with a history of spontaneous abortion 1 year prior. The patient denied pregnancy and even reported her last menstruation date on 3/23/09. She began with sudden abdominal pain associated with two episodes of diarrhea, dizziness and fainting. CONCLUSION: Uterine rupture is a rare clinical entity with an elevated perinatal mortality. Clinical suspicion is of vital important for early diagnosis and timely treatment.

RESUMO

The uterine rupture during pregnancy is one of the most serious complications, increase morbidity and maternal and fetal mortality. The uterine rupture by percrete placenta is rare. We present the case of a 39 years-old patient, pregnancy of 16.3 weeks by ultrasound, which enters by abdominal pain 48 hours of evolution, of predominance in the hypogastric region, that during its evolution presented hemodynamic compromise and increase of abdominal pain. By ultrasound: free liquid in abdominal cavity is observed. With laparothomy we found perforated uterus with placenta free and product in abdominal cavity, obstetrical hysterectomy was performed, we confirmed the diagnosis of uterine rupture by percrete placenta.

RESUMO

La rotura uterina es una complicación obstétrica infrecuente, pero potencialmente letal para la madre y el feto. Ocurre principalmente durante el segundo o tercer trimestre, asociada a factores de riesgo, entre los que destaca la cirugía uterina previa. Su aparición durante el primer trimestre es excepcional, constituyendo un desafío médico por su difícil diagnóstico diferencial y controversial manejo. Se presenta el caso de una paciente con rotura espontánea de útero grávido de 10 semanas de gestación, portadora de triple cicatriz anterior. El diagnóstico fue intraoperatorio, tras la descompensación hemodinámica de la paciente. El manejo incluyó el cierre primario de la lesión y observación posterior. Al sexto día se constata la muerte fetal y se efectúa el vaciamiento de la cavidad uterina. La falla de las medidas conservadoras obligó finalmente a realizar una histerectomía obstétrica. La histopatología informó placenta acreta.

Uterine rupture is an uncommon obstetric event, but still potentially lethal for the mother and the fetus. It presents mainly during the second or third trimester and is associated with several riskf actors, being a previous uterine scar the most important of them. Its presentation during the first trimester is exceptional, and it constitutes a medical challenge, because of its difficult differential diagnosis and controversial management. A case of a multiparous, previous triple scar woman is presented, with a spontaneous uterine rupture at 10 weeks of pregnancy. In this case the diagnosis was made during surgery, after the patient's hemodynamic decompensation. The management included primary closure of the lesion and observation; when fetal death was confirmed, dilatation and curettage of the cavity had to be performed. Because of the failure of conservative management, an obstetric hysterectomy was carried out. Histopathology reported placenta accreta.

RESUMO

A 71-year-old female with rheumatoid arthritis and chronic use of corticosteroids presented to the emergency room with 2 weeks of urinary symptoms, abdominal pain and a mass located in hypo-mesogastrium and both flanks. An X-ray film of the abdomen showed that bowels were displaced by the mass. Laboratory studies showed thrombocytosis (549,000/mm(3)) and leukocytosis (41,800/mm(3)). Several hours after her arrival the patient developed acute abdomen and surgery was indicated. A urinary catheter drained 2100 ml of urine and the abdominal mass was reduced in size but did not disappear. Surgery demonstrated that the urinary bladder covered the fundus and the anterior face of the uterus, where extensive necrosis and a 3-cm perforation were found; 400 ml of foul-smelling pus was drained from the uterine cavity. Due to necrosis, a hysterectomy was performed. The histopathological report indicated necrosis, atrophic cervicitis and endometritis; pus culture developed Escherichia coli and Proteus vulgaris. Despite administration of broad-spectrum antibiotics, the patient developed severe sepsis and died 11 days postoperatively. During a literature review, only one similar case was found. Acute abdomen due to uterine perforation secondary to pyometra and associated with chronic use of corticosteroids is a rare complication.
