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.

Uterine rupture after high-intensity focused ultrasound ablation of adenomyosis: a case report and literature review.

AIM: High-intensity focused ultrasound (HIFU) is a non-invasive treatment of adenomyosis. Uterine rupture during pregnancy is a rare adverse event after HIFU treatment, because HIFU treatment results in tissue coagulative necrosis. METHODS: We reported a case of uterine rupture in a 34-year-old woman. The woman had HIFU treatment for adenomyosis eight months before unplanned pregnancy. She was closely monitored during the pregnancy and the antenatal course was uneventful. At the gestational age of 38 weeks and 2 days, an emergency lower segment cesarean section was performed because of inexplainable abdominal pain. After delivery of the fetus, a 2 × 2 cm serous membrane rupture was observed in the HIFU treatment area. CONCLUSION: Uterine rupture during pregnancy after HIFU is a rare adverse event, however, attention is required during the whole pregnancy in case of unexpected uterine rupture.

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.

Spontaneous Uterine Vessel Rupture During Pregnancy or in the Puerperium: A Review of the Literature.

Importance: Spontaneous perinatal rupture of a uterine vessel is a rare occurrence that may lead to severe hemorrhage and requires prompt identification and management. Objective: The aim of this study was to examine the etiologies, locations, diagnostic tools, treatment options, and risks in subsequent pregnancies when spontaneous rupture of a uterine vessel occurs in pregnancy. Evidence Acquisition: A literature search was performed by university research librarians using the PubMed, CINAHL, and Web of Science search engines. Identified were 78 cases of perinatal spontaneous uterine vessel rupture and formed the basis for this review. Results: Increased uterine blood flow during pregnancy may alter the integrity of pelvic vessels leading to increased risk of spontaneous rupture. The uterine artery is the most common site of vessel rupture; the second most common site is the uterine-ovarian plexus. The most common presentation is abdominal or pelvic pain, maternal vital sign abnormalities, and an absence of vaginal bleeding. Exploratory laparotomy and embolization (interventional radiology) have been reported as management options. Conclusions: Spontaneous rupture of uterine vessels is a rare but potentially life-threatening complication of pregnancy that should be included in the differential diagnosis of pregnant patients presenting with an acute abdomen. Relevance: Our aim is to increase the awareness of spontaneous vessel rupture during pregnancy to improve detection, management, and perinatal outcomes.

Uterine Dehiscence and Subsequent Pregnancy Management: A Review of the Literature.

IMPORTANCE: Uterine dehiscence is a separation of the uterine musculature with intact uterine serosa. Uterine dehiscence can be encountered at the time of cesarean delivery, be suspected on obstetric ultrasound, or be diagnosed in between pregnancies. Management is a conundrum for obstetricians, regardless of timing of onset. EVIDENCE ACQUISITION: A literature search was undertaken by our research librarian using the search engines PubMed, CINAHL, and Web of Science. The search term used was "uterine dehiscence." The search was limited to the English language, and there was no limit on the years searched. RESULTS: The search identified 152 articles, 32 of which are the basis for this review. Risk factors, treatment, and management in subsequent pregnancies are discussed. The number of prior cesarean deliveries is the greatest risk factor for uterine dehiscence. Unrepaired uterine dehiscence can cause symptoms outside of pregnancies and may require repair for alleviation of these symptoms. Dehiscence should also be repaired prior to subsequent pregnancies. CONCLUSION AND RELEVANCE: Planned delivery prior to the onset of labor with careful monitoring of maternal symptoms is the preferred management strategy of women with prior uterine dehiscence. Careful attention should be paid to the lower uterine segment thickness when ultrasonography is performed in women with prior cesarean delivery. RELEVANCE STATEMENT: An evidence-based review of uterine dehiscence in pregnancy and how to manage subsequent pregnancies following uterine dehiscence.

Uterine-conserving approach in ruptured intramyometrial ectopic pregnancy.

Intramyometrial ectopic pregnancy (IMEP) is a rare form of ectopic pregnancy. It is defined as a conceptus implanted within the myometrium and is completely surrounded by myometrium with clear separation from both the uterine cavity and tubes. IMEP possesses not only diagnostic but also therapeutic challenge. The majority of reported cases were managed by hysterectomy. Early management of unruptured IMEP using methotrexate may help to preserve fertility. We, for the first time, report a case of ruptured IMEP managed successfully using suction and curettage followed by Bakri balloon tamponade and avoiding hysterectomy. Post-procedure, the patient received two doses of intramuscular methotrexate 50 mg/m2 due to plateauing serial beta human chorionic gonadotropin (ß-hCG) levels and subsequently achieved undetectable level 10 weeks post-methotrexate. She also had complete resolution of the ectopic intramyometrial mass.

Un caso de rotura uterina durante el embarazo / A case of uterine rupture during pregnancy

Este artículo presenta un caso poco habitual de ruptura uterina durante la 19ª semana de gestación en el lugar de la cicatriz de una cesárea realizada dos años antes. El feto estaba todavía vivo, pero murió pocos minutos después debido a su inmadurez. Se consiguió preservar el útero, aconsejando vivamente a la mujer el no volver a quedar embarazada, y sugiriendo realizar la ligadura de trompas. En estas páginas se examina la literatura sobre la ruptura uterina, en concreto, la que se produce tras una intervención cesárea, valorando la posibilidad de calcular el riesgo de ruptura a través del estudio ecográfico. A continuación se ofrece el análisis moral del caso desde la perspectiva de la moral católica, preguntándose concretamente por la licitud de la histerectomía en ciertas condiciones. Se recuerda la ilicitud de toda esterilización directa, o sea, de aquellas intervenciones que se proponen impedir la procreación. Al mismo tiempo se explica que algunas operaciones en este ámbito pueden no configurarse como esterilización directa, cuando se llegue a la certeza moral de que el útero, por las condiciones en las que se encuentra, no será capaz de desarrollar un embarazo hasta la viabilidad del feto. En estos casos la intervención no puede decirse antiprocreativa porque el sistema reproductivo de la mujer es incapaz de cumplir su función natural

The article presents a rare case of uterine rupture at the 19th week of gestation, in the presence of a scar after a caesarean section practiced two years earlier. The fetus was pulled out alive, but given the gestational age, died within a few minutes. The uterus was preserved, but the woman was advised to proceed with tubal ligation and, in any case, to absolutely avoid a new pregnancy. The literature on uterine rupture is examined focusing on the problem of uterine rupture resulting after a caesarean section, analyzing the possibility of monitoring the risk of rupture through ultrasound evaluation. Finally, the article conducts a moral analysis of the case in the light of personal bioethics, questioning in particular the acceptability of a hysterectomy under certain conditions. The illegitimacy of direct sterilization is reaffirmed, that is to say, an intervention whose purpose is the impediment of procreation, but it is emphasized that direct sterilization cannot occur when it comes to the moral certainty that that uterus, because of its conditions , cannot carry on a pregnancy until the viability of the fetus. In fact, an intervention that affects a uterus that is objectively incapable of carrying out its natural function cannot be qualified as anti-procreative

Uterine scar rupture - Prediction, prevention, diagnosis, and management.

The increasing rate of elective and indicated caesarean sections worldwide has led to new pathologies and management challenges. The number of patients undergoing trial of labor after caesarean section (TOLAC) is also increasing. Three professional societies provide detailed guidelines based on scientific evidence for the management of patients attempting vaginal birth after caesarean section (VBAC). However, they do not provide any recommendations for the actual surgical steps to be followed to minimize the risks of uterine rupture (UR) during TOLAC. Uterine scar condition, intrapartum management and maternal health status correlate to uterine scar rupture risk and provide guidance for parturient TOLAC eligibility. TOLAC and vaginal delivery success rate as reported by the largest studies is between 60% and 77%. Uterine rupture is more prevalent in VBAC-2 patients (1.59%) in contrast to VBAC-1 (0.72%). Additionally, VBAC-2 patients have higher incidence of caesarean hysterectomy 0.56% vs. 0.19% for VBAC-1. The chances of successful VBAC increase when the interpregnancy/interdelivery interval is less than 6.3 years and less than 24 months, respectively. No difference was detected between the techniques of uterine incision closure of the previous CS and TOLAC results, although closure of the CS uterine incision in 2 layers seems to be practiced more widely. Niche or isthmocele presents another complication of CS. Secondary infertility due to niche, will eventually direct to hysteroscopic or laparoscopic repair, depending on the residual myometrial thickness (RMT) as measured by US scan. When RMT is below 3 mm or 2.5 mm surgery can be performed, to prevent any spontaneous UR in case of pregnancy. Monitoring by US scanning of hysterotomy scar after myomectomy can detect hematoma. In patients with severe postoperative pain but hemodynamically stable follow up by US scan examination can direct the management decision. In those patients with active bleeding and deterioration of hysterotomy scar edema will be an indication to surgery. There is no firm evidence regarding which type of thread, knotting or sequence of suturing is more favorable to reduce the risk of UR after VBAC or hysterotomy after myomectomy.

Maternal and perinatal outcomes of uterine rupture in a tertiary care hospital: a cross-sectional study.

Objective: The current study aims to evaluate the incidence, maternal and perinatal outcomes in cases presented with uterine rupture (UR) and to explore the differences in presentation, management and outcome of UR in patients with scarred versus unscarred uterus. Materials and methods: A cross-sectional study conducted in a tertiary care hospital over a period of 2 years. The study included all women diagnosed with UR and admitted to the emergency unit between January 2016 and December 2017. A structured questionnaire was used to collect the preoperative demographic and clinical data. An observation checklist was used for intraoperative findings and management. Postoperative data were collected about maternal and fetal outcomes. Data were analyzed using SPSS software. Qualitative variables were compared between groups using chi-square test while quantitative variables were compared using the Mann-Whitney test. Results: Sixty two women were diagnosed with uterine rupture (0.32% of all deliveries). The mean age of the included patients was 29.6 ± 5.6 years while the mean parity was 3.0 ± 1.8. Uterine repair was successful in 52 cases (83.9%). There were four (6.5%) maternal deaths and 42 (67.8%) perinatal deaths. Ten patients (16.1%) were transferred to the postoperative intensive care unit (ICU). Re-exploration was carried out in three cases. The most common complication of UR was disseminated intravascular coagulopathy (DIC) occurred in eight women (12.9%). Maternal and perinatal mortality were significantly higher in patients with unscarred uterus (p = .0001 and .026, respectively). Conclusions: The incidence of UR is 32/10,000 deliveries in our tertiary hospital. Rupture of unscarred uterus is associated with more maternal and fetal mortality. However, rupture of scarred uterus was more common due to the rising rate of cesarean sections.

Pregnancy in Women With a History of Uterine Rupture.

IMPORTANCE: With increased rates of primary and repeat cesarean deliveries, the potential for uterine rupture and management of women with a history of uterine rupture has also increased. Taking care of a pregnant woman with a prior uterine rupture requires understanding of the risks, the need for additional surveillance, and the limitations of our knowledge about how rupture affects subsequent pregnancies. OBJECTIVE: The aims of this study were to review the literature on pregnancy after uterine rupture and to summarize the evidence to help the obstetrician care for a pregnant woman with a history of uterine rupture. EVIDENCE ACQUISITION: Evidence for this review was acquired using PubMed. CONCLUSIONS: Pregnancy after uterine rupture carries a risk of spontaneous repeat rupture before the onset of labor and of repeat rupture during early labor. Elective cesarean delivery before the onset of labor is the safest strategy to prevent maternal and neonatal morbidity and mortality. However, more research is needed to better inform risk estimates and to guide management of pregnant women with a history of uterine rupture. RELEVANCE: Obstetricians will increasingly be caring for women who have experienced uterine rupture and subsequently become pregnant.

[Obstetrics]. / Obstétrique.

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.

Au cours de l'année écoulée, l'intérêt pour de vieux problèmes bien connus de notre spécialité médicale a été renouvelé. De nouvelles études et lignes directrices ont été publiées concernant la maturation pulmonaire en cas d'accouchement prématuré après 37 semaines de gestation. Bien qu'un bénéfice à court terme ait été prouvé, le nombre de cas à traiter pour prévenir une complication respiratoire néonatale est élevé, avec des effets neurologiques potentiels à long terme. Afin de promouvoir la tentative d'accouchement vaginal après césarienne sans augmenter le risque de rupture utérine, différents travaux indiquent qu'il faut intégrer la mesure du segment inférieur de l'utérus dans la discussion de la voie d'accouchement. D'autres ont montré la meilleure procédure pour fermer l'utérus pendant la césarienne. Enfin, nous allons parler d'une vieille amie : l'aspirine pour réduire le risque de prééclampsie.

Treatment for Uterine Isthmocele, A Pouchlike Defect at the Site of a Cesarean Section Scar.

An isthmocele appears as a fluid pouchlike defect in the anterior uterine wall at the site of a prior cesarean section and ranges in prevalence from 19% to 84%, a direct relation to the increase in cesarean sections performed worldwide. Many definitions have been suggested for the dehiscence resulting from cesarean sections, and we propose standardization with a single term for all cases-isthmocele. Patients are not always symptomatic, but symptoms typically include intermittent abnormal bleeding, pain, and infertility. Pregnancy complications that result from an isthmocele include ectopic pregnancy, low implantation, and uterine rupture. Magnetic resonance imaging and transvaginal ultrasound are the gold standard imaging techniques for diagnosis. Surgical treatment of an isthmocele is still a controversial issue but should be offered to symptomatic women or the asymptomatic patient who desires future pregnancy. When surgery is the treatment choice, laparoscopy guided by hysteroscopy, hysteroscopy alone, or vaginal repair are the best options depending on the isthmocele's characteristics and surgeon expertise.

Uterine rupture: socio-demographic aspects, etiology and therapy at the University Clinic of Gynecology and Obstetrics of the National Donka Hospital in Conakry University Hospital, Guinea.

Uterine rupture is an obstetric catastrophe that has become rare in developed countries. In developing countries, including Guinea, however, it remains a major concern of obstetricians. The objectives of this work were to calculate the frequency of uterine rupture in our département, describe the women's social and demographic characteristics, identify factors predisposing them to uterine rupture, describe its treatment, and assess maternal and fetal prognosis. Data for this descriptive study were collected in 2 phases, with a retrospective review of files covering the 3-year period from April 1, 2011, to March 31, 2014, followed by prospective data collection for the 6-month period from April 1 to September 30, 2014. This study of uterine rupture took place at the maternity unit of Donka National Hospital (CHU Conakry). We identified 98 cases of uterine rupture among 26 827 births, for a frequency of 0.36%. The women's mean age was 28.4 years (range: 16-43 years). The socio-demographic profile of the women admitted for uterine rupture was that of a housewife (50%), with two or three previous deliveries (41.84%), and who had no prenatal care (58.17%). Most of the ruptures took place in birthing centers, outlying maternity units, or during the journey to reach our reference department (87.16%). Most uterine ruptures were iatrogenic (69.38%) and occurred on an non cicatriciel uterus (62.24%). The rupture was most often complete. Most surgical treatment was conservative, by hysterorrhaphy (80.61%). Four women died, for a lethality rate of 4.80%. Almost all women were admitted without signs of fetal life. The role of uterine rupture in the obstetric activity in this service requires joint and urgent action by all stakeholders in the health system to combat this catastrophic complication that is evidence of a poor quality of obstetric care.

Confirmation of posterior uterine rupture in the second trimester by magnetic resonance imaging.

Intrapartum uterine rupture is a life-threating and rare complication of pregnancy which seldom occurs in the second trimester. Typically, the diagnosis is made using ultrasound; however, magnetic resonance imaging can provide certain advantages in the emergent setting. We present a unique case of a posterior uterine rupture confirmed by magnetic resonance imaging involving the unscarred posterior uterine wall in a 20-year-old gravid female with two previous cesarean-sections.

Medical management of early pregnancy failure with misoprostol with rupture of the cesarean section scar pregnancy.

PURPOSE: To report a case of ruptured uterus in the first trimester with the use of misoprostol for early pregnancy tailure in a woman with unrecognized cesarean section scar pregnancy. CASE: A 27-year-old woman, gravida 5 para 3+1, presented with abdominal pain and vaginal bleeding. Transvaginal ultrasonography revealed a fetus without fetal heart activity at nine weeks gestation, making the diagnosis of early pregnancy failure. Her previous deliveries were by cesarean section. She was managed medically with misoprostol. Seven hours after misoprostol administration, she developed sudden onset of severe abdominal pain. Repeat transvaginal ultrasonography diagnosed cesarean section scar pregnancy. Laparotomy revealed hemoperitoneum with rupture of cesarean section scar pregnancy. Subtotal hysterectomy was performed. CONCLUSIONS: Failure to recognize cesarean section scar pregnancy can result in a ruptured uterus in the first trimester with the use of misoprostol for early pregnancy failure. Increased awareness of the unexpected consequences of cesarean section is of paramount importance.

Perinatal Asphyxia from the Obstetric Standpoint: Diagnosis and Interventions.

Perinatal asphyxia is a general term referring to neonatal encephalopathy related to events during birth. Asphyxia refers to a deprivation of oxygen for a duration sufficient to cause neurologic injury. Most cases of perinatal asphyxia are not necessarily caused by intrapartum events but rather associated with underlying chronic maternal or fetal conditions. Of intrapartum causes, obstetric emergencies are the most common and are not always preventable. Screening high-risk pregnancies with ultrasound, Doppler velocimetry, and antenatal testing can aid in identifying fetuses at risk. Interventions such as intrauterine resuscitation or operative delivery may decrease the risk of severe hypoxia from intrauterine insults and improve long-term neurologic outcomes.

Preventing deaths due to haemorrhage.

Prevention of deaths from obstetric haemorrhage requires effective health systems including family planning, commodities, personnel, infrastructure and ultimately universal access to comprehensive obstetric care for women giving birth. The main causes of death associated with antepartum haemorrhage are placental abruption, placenta praevia and uterine rupture. Preventive measures include preconceptual folate supplementation, management of hypertensive disorders, early diagnosis of placenta praevia and use of uterine stimulants cautiously, particularly misoprostol. Preventive measures for post-partum haemorrhage include routine active management of the third stage of labour. Treatment involves a cascade of increasingly invasive interventions in rapid sequence until the bleeding is stopped. These interventions include fluid resuscitation, removal of the placenta, bimanual uterine compression, uterotonics, tranexamic acid, suturing of lower genital tract injury, blood product replacement, balloon tamponade, laparotomy, stepwise uterine devascularization, uterine compression sutures and hysterectomy. Emergency temporizing measures include application of the non-pneumatic anti-shock garment, and at laparotomy, aortic compression and uterine tourniquet application. The effectiveness of treatment methods and the optimal dosage of misoprostol are research priorities. Interesting new approaches include transvaginal uterine artery clamping and suction uterine tamponade.

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.

An economic analysis of trial of labor after cesarean delivery.

OBJECTIVE: Given that cesarean delivery is one of the most commonly performed surgical procedures in the United States and an important contributor to obstetric care costs, this analysis sought to examine maternal hospital costs associated with trial of labor after cesarean delivery (TOLAC) versus repeat cesarean delivery (RCD). METHODS: A national sample was used to identify women with singleton pregnancy who underwent either TOLAC or RCD from 2006 to 2012. Women with diagnoses that could confound cost via extended hospital length of stay prior to delivery were excluded. Other medical and obstetric covariates that could influence cost were included in an adjusted model. RESULTS: A total of 485,247 women were identified, including 365,596 (75.3%) cesarean deliveries without labor, 41,988 (8.6%) successful and 77,663 (16.0%) unsuccessful TOLAC deliveries. The inflation-adjusted median costs in this cohort were $5512 for cesarean without labor, $4175 for successful TOLAC, $5166 for all TOLAC attempts, and $5759 for failed TOLAC. In a multivariable model, hospital region was a major predictor of median cost as were demographic variables and medical comorbidities. CONCLUSION: TOLAC is associated with modest reductions of cost for maternal hospitalizations. However, other medical, demographic and hospital factors appear to be more important factors.
