Rotura uterina durante el segundo trimestre de gestación asociado a placenta percreta: presentación de un caso y revisión de la literature / Uterine rupture during the second trimester of pregnancy associated with placenta percreta: presentation of a case and review of the literature

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.

Simultaneous Uterine and Bladder Rupture Following Successful Vaginal Birth After Cesarean Delivery: Laparoscopic Repair of Defect.

When gross hematuria occurs after a successful vaginal birth after cesarean section, bladder injury should be suspected. We report a postpartum patient who experienced progressively worsening abdominal pain a few hours after delivery and was found to have a simultaneous bladder and uterine rupture, which were successfully repaired via a laparoscopic approach. This case highlights a laparoscopic approach to repairing both defects in the immediate postpartum period.

Risk factors of uterine rupture with a special interest to uterine fundal pressure.

PURPOSE: Uterine rupture is a rare but serious event with a median incidence of 0.09%. Previous uterine surgery is the most common risk factor. The aim of our study was to analyze retrospectively women with uterine rupture during labor and to evaluate postulated risk factors such as uterine fundal pressure (UFP). METHODS: Twenty thousand one hundred and fifty-two deliveries were analyzed retrospectively. Inclusion criteria were 22 weeks and 0 days-42 weeks and 0 days of gestation, singleton pregnancy and cephalic presentation. Women with primary cesarean section were excluded. A logistic regression analysis adjusting for possible risk factors was conducted and a subgroup analysis of women with unscarred uterus was performed. RESULTS: Twenty-eight cases of uterine rupture were identified (incidence: 0.14%). Uterine rupture was noticed in multipara patients only. In the multivariate analysis among all study patients, only previous cesarean section remained a statistically significant risk factor [adjusted odds ration (adj. OR) 12.52 confidence interval (CI) 95% 5.21-30.09]. In the subgroup analysis among women with unscarred uterus (n=19,415) three risk factors were associated with uterine rupture: UFP (adj. OR 5.22 CI 95% 1.07-25.55), abnormal placentation (adj. OR 20.82 CI 95% 2.48-175.16) and age at delivery >40 years (adj. OR 4.77 CI 95% 1.44-15.85). CONCLUSIONS: The main risk factor for uterine rupture in the whole study population is previous uterine surgery. Risk factors in women with unscarred uterus were UFP, abnormal placentation, and age at delivery >40 years. The only factor which can be modified is UFP. We suggest that UFP should be used with caution at least in presence of other supposed risk factors.

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.

Ruptured uterus and bowel injury from manual removal of placenta: a case report.

BACKGROUND: Retained placenta is a significant cause of maternal mortality and morbidity throughout the developing world. 'Though, intestinal injury may arise as a complication of induced abortion following instrumentation through the genital tract, the involvement of the large bowel in complicated manual removal of placenta is a very rare occurrence CASE REPORT: We present the case of a 28 year-old Para 3+0, 3 alive woman who had attempted manual removal of placenta in a basic emergency obstetric care facility that resulted in lower uterine segment rupture with evisceration of bowels through the laceration outside the introitus. She subsequently had right hemi- colectomy with ileo-transverse anastomosis and repair of uterine rupture with bilateral tubal ligation. CONCLUSION: This case highlights the risk of exposing parturients to inexperienced attendants at delivery and emphasises the need for intensification of manpower training to attain the 5th MDG enunciated by the United Nations.

Isolated impairment of posterior pituitary function secondary to severe postpartum haemorrhage due to uterine rupture.

Cranial diabetes insipidus (DI) due to postpartum haemorrhage is an extremely rare clinical event. We describe herein isolated posterior pituitary insufficiency in a 26-year-old woman who had undergone subtotal hysterectomy for severe postpartum haemorrhage because of uterine rupture. The patient experienced polyuria within 6 h postoperatively. DI was suggested by the elevated urine volumes and low urine specific gravity. The diagnosis of DI was confirmed by water deprivation test and vasopressin stimulation test. The anterior pituitary function was within normal limits. A high clinical suspicion is certainly required for the diagnosis of DI in the immediate postpartum period. To rapidly initiate appropriate therapy, the possibility of DI should always be kept in mind while evaluating patients who have polyuria and polydipsia after severe postpartum bleeding. Delay or failure to treat this condition might result in hypovolemic shock.

Uterine rupture following a road traffic accident.

A nulligravida presented in traumatic shock and suffered pelvic trauma, including an absolute uterine rupture at the isthmus. Her uterus was reconstructed by reconnecting the uterine corpus with the cervix in an emergency surgery. Two years later, the patient became pregnant without any assisted technology.

[Life threatening postpartal haemorrhage after rupture of the vagina, uterine cervix, caesarean section or hysterectomy].

The authors discuss 10 cases--seven after vaginal and cervical rupture, 2 after Caesarean section and 1 after hysterectomy. Six of them died--5 after rupture of the vagina and cervix and one after Caesarean section. The lethal issue was avoidable in all cases because it was a result of untimely done or not done at all hysterectomy and other interventions, e.g., ligation of the hypogastric arteries, as well as of faulty surgical performance. Basic principles of surgical behavior in such cases are postulated.

Maternal and neonatal outcomes after uterine rupture in labor.

OBJECTIVE: There is significant controversy about the risks related to attempted vaginal birth after cesarean and the implications for informed consent of the patient. Recent data suggest that women who deliver in hospitals with high attempted vaginal birth after cesarean rates are more likely to experience successful vaginal birth after cesarean, as well as uterine ruptures. We conducted a study to evaluate maternal and neonatal morbidity and mortality after uterine rupture at a tertiary care center. STUDY DESIGN: We performed a retrospective chart review of cases of uterine rupture from 1976 to 1998. All women who had a history of uterine rupture were identified with International Classification of Diseases, Ninth Revision, identifiers with hospital discharge data cross-referenced with a separate obstetric database. We abstracted demographic information, fetal heart rate patterns, maternal pain and bleeding patterns, umbilical cord gas values, and Apgar scores from the medical record. Outcome variables were uterine rupture events and major and minor maternal and neonatal complications. RESULTS: During the study period there were 38,027 deliveries. The attempted vaginal birth after cesarean rate was 61.3%, of which 65.3% were successful. We identified 21 cases of uterine rupture or scar dehiscence. Seventeen women had prior cesarean deliveries (10 with primary low transverse cesarean delivery, 3 with unknown scars, 1 with classic cesarean delivery, 2 with two prior cesarean deliveries, and 1 with four prior cesarean deliveries). Of the 4 women who had no history of previous uterine surgery, one had a bicornuate uterus whereas the others had no factors increasing the risk for uterine rupture. We confirmed uterine rupture and scar dehiscence in 19 women. Specific details were not available for 2 patients. Uterine rupture or scar dehiscence was clinically suspected in 16 women with 3 cases identified at delivery or after delivery. Sixteen women had symptoms of increased abdominal pain, vaginal bleeding, or altered hemodynamic status. There were 2 patients who required hysterectomies and 3 women who received blood transfusions; there were no maternal deaths related to uterine rupture. The fetal heart rate pattern in 13 cases showed bradycardia and repetitive variable or late decelerations. Thirteen neonates had umbilical artery pH >7.0. Two cases of fetal or neonatal death occurred, one in a 23-week-old fetus whose mother had presented to an outlying hospital and the second in a 25-week-old fetus with Potter's syndrome. All live-born infants were without evidence of neurologic abnormalities at the time of discharge. CONCLUSION: Our data confirm the relatively small risk of uterine rupture during vaginal birth after cesarean that has been demonstrated in previous studies. In an institution that has in-house obstetric, anesthesia, and surgical staff in which close monitoring of fetal and maternal well-being is available, uterine rupture does not result in major maternal morbidity and mortality or in neonatal mortality.

Pyometra. What is its clinical significance?

OBJECTIVE: To evaluate the clinical outcomes of pyometra. STUDY DESIGN: Retrospective study conducted between 1993 and 1999 in two regional hospitals. RESULTS: Pyometra represented 0.038% of gynecologic admissions. Of the 27 women with pyometra, 6 (22.2%) cases were associated with malignancy, 1 (3.7%) was associated with genital tract abnormality, and 20 (74.1%) were idiopathic. Patients with idiopathic pyometra tended to be older and had a higher incidence of concurrent medical conditions. Five (18.5%) women experienced spontaneous perforation of pyometra. A preoperative diagnosis was correctly made in 17 of 22 (77.3%) patients without spontaneous perforation. Most women were treated with dilatation of the cervix and drainage. Nine women (33.3%) had persistent or recurrent pyometra; three of them were asymptomatic. CONCLUSION: Pyometra is an uncommon condition, but the incidence of associated malignancy is considerable, and the risk of spontaneous perforation is higher than previously thought. Dilatation and drainage is the treatment of choice, and regular monitoring after initial treatment is warranted to detect persistent and recurrent disease.

Diagnostic potential of cardiotocography (CTG) for silent uterine rupture.

We report on 3 patients with silent rupture of previous uterine scars. Despite continuous monitoring by cardiotocography, diagnosis was not made until the time of surgery. The cesarean section was indicated by the obstetrical-clinical examination, while CTG offered no evidence of uterine rupture.

Uterine rupture secondary to a malignant mixed mesodermal (mullerian) tumor: a case report.

A case of uterine rupture resulting from tumor penetration of the myometrium in a patient with malignant mixed mesodermal tumor is described; the first in the literature known to the authors. Notable features include rapid progression of disease, hemoperitoneum, and diffuse intraoperative bleeding controlled by radiographic embolization.
