Pyometra Puzzler: Unraveling Senile Endometritis in an Unconventional Presentation.

Pyometra is a very uncommon condition in postmenopausal women that rarely improves with standard antibiotic treatments. It is usually overlooked as the patient presents with vague symptoms. Our case presented a postmenopausal woman with sepsis due to a huge pyometra. Swabs for sensitivity, tubercular gene testing, and basic blood workup were done, and the patient was started on intravenous antibiotic therapy. Pyometra drainage could not be done due to thin, friable uterine walls. When the patient had improved, a clinically total abdominal hysterectomy was done after ruling out malignant causes. Delay in the diagnosis of this condition may lead to perforation, which may, in turn, cause peritonitis, which may gravely affect the patient.

The global burden, risk and inequality of maternal obstructed labor and uterine rupture from 1990 to 2019.

BACKGROUND: Obstructed labor (OL) and uterine rupture (UR) are common obstetric complications. This study explored the burden, risk factors, decomposition, and health inequalities associated with OL and UR to improve global maternal health. METHODS: This was a cross-sectional analysis study including data on OL and UR from the Global Burden of Diseases, and Risk Factors Study (GBD) 2019. The main outcome measures included the number and age-standardized rate (ASR) of incidence, disability-adjusted life years (DALYs), prevalence, and deaths. RESULTS: The global burden of OL and UR has declined, with a decrease in incidence (number in 2019: 9,410,500.87, 95%UI 11,730,030.94 to 7,564,568.91; ASR in 2019: 119.64 per 100,000, 95%UI 149.15 to 96.21; estimated annual percentage change [EAPC] from 1990 to 2019: -1.34, 95% CI -1.41 to -1.27) and prevalence over time. However, DALYs (number in 2019: 999,540.67, 95%UI 1,209,749.35 to 817,352.49; ASR in 2019: 12.92, 95%UI 15.63 to 10.56; EAPC from 1990 to 2019: -0.91, 95% CI -1.26 to -0.57) and deaths remain significant. ASR of DALYs increased for the 10-14 year-old age group (2.01, 95% CI 1.53 to 2.5), the 15-19 year-old age group (0.07, 95% CI -0.47 to 0.61), Andean Latin America (3.47, 95% CI 3.05 to 3.89), and Caribbean (4.16, 95% CI 6 to 4.76). Iron deficiency was identified as a risk factor for OL and UR, and its impact varied across different socio-demographic indices (SDIs). Decomposition analysis showed that population growth primarily contributed to the burden, especially in low SDI regions. Health inequalities were evident, the slope and intercept for DALYs were - 47.95 (95% CI -52.87 to -43.02) and - 29.29 (95% CI -32.95 to -25.63) in 1990, 39.37 (95%CI 36.29 to 42.45) and 24.87 (95%CI 22.56 to 27.18) in 2019. Concentration indices of ASR-DALYs were - 0.2908 in 1990 and - 0.2922 in 2019. CONCLUSION: This study highlights the significant burden of OL and UR and emphasizes the need for continuous efforts to reduce maternal mortality and morbidity. Understanding risk factors and addressing health inequalities are crucial for the development of effective interventions and policies to improve maternal health outcomes globally.

Maternal Morbidity following Trial of Labor after Cesarean in Women Experiencing Antepartum Fetal Death.

This study aims to investigate whether trial of labor after cesarean delivery (TOLAC) in women with antepartum fetal death, is associated with an elevated risk of maternal morbidity. A retrospective multicenter. TOLAC of singleton pregnancies following a single low-segment incision were included. Maternal adverse outcomes were compared between women with antepartum fetal death and women with a viable fetus. Controls were matched with cases in a 1:4 ratio based on their previous vaginal births and induction of labor rates. Univariate analysis was followed by multiple logistic regression modeling. During the study period, 181 women experienced antepartum fetal death and were matched with 724 women with viable fetuses. Univariate analysis revealed that women with antepartum fetal death had significantly lower rates of TOLAC failure (4.4% vs. 25.1%, p < 0.01), but similar rates of composite adverse maternal outcomes (6.1% vs. 8.0%, p = 0.38) and uterine rupture (0.6% vs. 0.3%, p = 0.56). Multivariable analyses controlling for confounders showed that an antepartum fetal death vs. live birth isn't associated with the composite adverse maternal outcomes (aOR 0.96, 95% CI 0.21-4.44, p = 0.95). TOLAC in women with antepartum fetal death is not associated with an increased risk of adverse maternal outcomes while showing high rates of successful vaginal birth after cesarean (VBAC).

Accidental uterine extensions in cesarean deliveries - outcome of subsequent pregnancy.

OBJECTIVES: To explore the obstetric, maternal and neonatal outcome in the subsequent pregnancy after a pregnancy with an accidental uterine extension (AUE) during cesarean delivery (CD), as well as the relationship between the different types of AUE (inferior, lateral and superior). METHODS: A retrospective cohort study of all CD with AUE in a tertiary medical center between 01/2011-01/2022. Women with a prior CD with AUE were compared to a 1:3 ratio matched control group of women with a prior CD without AUE. All AUE were defined in their direction, size and mode of suturing. CD with deliberate uterine extensions were excluded. We evaluated obstetric, maternal and neonatal outcomes in the subsequent pregnancy after a pregnancy with AUE during CD. RESULTS: Comparing women with a prior CD with AUE (n=177) to the matched control group of women with a prior CD without AUE (n=528), we found no significant differences in proportions of uterine rupture or any other major complication or adverse outcome between the groups. There were no significant differences in the outcomes of the subsequent pregnancy in relation to the characteristics of the AUE (direction, size and mode of suturing). CONCLUSIONS: Subsequent pregnancies after AUE are not associated with higher maternal or neonatal adverse outcomes including higher proportions of uterine rupture compared to pregnancies without previous AUE. Different characteristics of the AUE do not impact the outcome.

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.

Accuracy of sonographic lower segment thickness and prediction of vaginal birth after caesarean in a resourced-limited setting; Prospective study.

OBJECTIVES: To assess the accuracy of ultrasound measurement of the lower uterine segment (LUS) thickness against findings at laparotomy, and to investigate its correlation with the success rate of vaginal birth after one previous caesarean delivery (CD) in a resource-limited setting. DESIGN: Prospective study. SETTING: Obstetrics and Gynaecology department in a tertiary hospital in Ghana. POPULATION: Women with one previous CD undergoing either a trial of labour (TOLAC) or elective CD. METHODS: Myometrial lower uterine segment thickness (mLUS) and full lower uterine segment thickness (fLUS) were measured with transvaginal ultrasound (TVUS). The women were managed according to local protocols with the clinicians blinded to the ultrasound measurements. The LUS was measured intraoperatively for comparison with ultrasound measurements. MAIN OUTCOME MEASURES: Lower uterine segment findings at laparotomy, successful vaginal birth. RESULTS: A total of 311 pregnant women with one previous CD were enrolled; 147 women underwent elective CD and 164 women underwent a TOLAC. Of the women that underwent TOLAC, 96 (58.5%) women had a successful vaginal birth. The mLUS was comparable to the intraoperative measurement in the elective CD group with LUS thickness <5 mm (bias of 0.01, 95% CI -0.10 to 0.12 mm) whereas fLUS overestimated LUS <5 mm (bias of 0.93, 95% CI 0.80-1.06 mm). Successful vaginal birth rate correlated with increasing mLUS values (odds ratio 1.30, 95% CI 1.03-1.64). Twelve cases of uterine defect were recorded. LUS measurement ≤2.0 mm was associated with an increased risk of uterine defects with a sensitivity of 91.7% (95% CI 61.5-99.8%) and specificity of 81.8% (95% CI 75.8-86.8%). CONCLUSION: Accurate TVUS measurement of the LUS is technically feasible in a resource-limited setting. This approach could help in making safer decisions on mode of birth in limited-resource settings.

Early diagnosis of impending rupture uterus during U/S: A case report.

INTRODUCTION AND IMPORTANCE: Uterine rupture is a rare condition that typically occurs in a scarred uterus and can happen during late pregnancy, labor, or the early postpartum period. Since most cases are seen in patients with a history of cesarean surgery, the anterior lower uterine segment is the most affected area. Most patients present with acute symptoms that compromise the fetus and the mother in a life-threatening manner. CASE PRESENTATION: We present a case of uterine rupture with subacute symptoms occurring in the second trimester, which is extremely rare. The patient was a stable second-trimester multiparous woman with chronic abdominal pain, but without any signs of peritoneal bleeding or instability. No history of previous cesarean section was present, and she had recently undergone a non-complicated hysteroscopic polypectomy. Transabdominal and transvaginal ultrasounds were performed, revealing a significant full-thickness myometrial defect in the posterior uterine lower segment. This defect allowed the amniotic sac to protrude into the posterior cul-de-sac. No abdominopelvic hematoma was detected. These findings were confirmed in an urgent MRI, and the patient underwent a laparotomy during which a significant full-thickness defect was discovered at the posterior of the uterus. As it was impossible to continue the pregnancy, the fetus was surgically removed and then prepared using multiple layers. CLINICAL DISCUSSION: The difference between our case and the previously reported one is in the aspect of gradual stable presentation and lacks of vaginal bleeding. CONCLUSION: Previous hysteroscopy carries a risk for future pregnancy complications, such as uterine rupture.

Perioperative complications in women undergoing thermal balloon endometrial ablation after one or more cesarean deliveries.

OBJECTIVE: To determine whether thermal ballon endometrial ablation can be safely performed after one or more cesarean sections. STUDY DESIGN: Retrospective cohort study including all women who underwent thermal balloon endometrial ablation at the Kepler University Hospital, Austria, between November 2017 and December 2022. For the analysis of the study endpoints, the dataset was divided into two groups: women with at least one cesarean section, and women without a history of cesarean section. Complications were classified according to the Clavien-Dindo classification. Association was tested using Fisher's exact test. RESULTS: Of the 361 women included, 29.3 % (n = 105) had at least one previous cesarean section. The association between intraoperative uterine rupture and previous cesarean section was not statistically significant (0 % vs. 1 %; p = 0.292). Only one uterine rupture was observed in the cesarean section group, which was located at the uterine fundus after a preoperatively unknown previous uterine perforation during IUD insertion. Secondary endpoints (overall complication rate, postoperative endometritis, vesicouterine fistula, different grades of Clavien-Dindo-classification) showed no significant associations either, even when considering the number of previous cesarean sections. The readmission rate to the clinic for bleeding disorders was 11.4 % in both groups (p = 1.00). CONCLUSION: Women who have had one or more prior cesarean sections with transverse isthmocervical hysterotomy do not appear to have an increased risk of complications in a subsequent thermal balloon endometrial ablation.

[Retrospective study of 60 cases of uterine rupture at the Maternity Center of Monastir, Tunisia]. / Etude rétrospective sur 60 cas de rupture utérine du centre de maternité de Monastir, Tunisie.

Uterine rupture is a life-threatening obstetric complication. The purpose of this study was to investigate the epidemiological features, maternal and foetal prognosis and different treatment options for uterine rupture in healthy and scarred uteri. We conducted a retrospective monocentric descriptive and analytical study of 60 cases of uterine rupture collected in the Department of Gynaecology-Obstetrics of the Center of Maternity and Neonatology, Monastir, from 2017 to 2021. Patients were classified according to the presence or absence of a uterine scar. Sixty patients were enrolled in the study. The majority of cases of rupture occurred in patients with scarred uterus (n=55). The most common clinical sign was abnormal foetal heart rate. No maternal deaths were recorded and perinatal mortality rate was 11%. Mean BMI, fetal macrosomia rate and mean parity were significantly higher in the healthy uterus group than in the scarred uterus group (p=0.033, 0.018, and 0.013, respectively). The maternal complications studied (post-partum haemorrhage, hysterectomy, blood transfusion, prolonged hospitalisation) were significantly more frequent in patients with unscarred uterine rupture (p=0.039; p=0.032; p=0.009; p=0.025 respectively). Uterine rupture is a life-threatening obstetrical event for the foetus and the mother. Fetal heart rate abnormality is the most common sign associated with uterine rupture. Management is based on conservative treatment in most cases. Patients with scarred uterus have a better prognosis.

Management of Interstitial Ectopic Pregnancy in a Bicornuate Uterus Simulating an Incomplete Abortion.

The presentation of a bicornuate uterus may include miscarriages and menstrual abnormalities. The diagnosis could be in an incident of caesarean delivery, miscarriage or hysteroscopy. The possibility of misdiagnosis to an ectopic pregnancy is real. There are sonographical similarities between a pregnant horn of a bicornuate uterus and an ectopic pregnancy. We present in this article a case of interstitial pregnancy in a woman with a bicornuate uterus simulating symptoms of miscarriage. Congenital abnormalities necessitate the availability of the best diagnostic tools at the disposal of the medical practitioners. Ultrasound scan is an important aid for practitioners to choose the best therapeutic approach.

Complete rupture of the pregnant uterus: A 12-year retrospective study.

OBJECTIVE: To assess the frequency of uterine ruptures, clinical characteristics, and maternal and neonatal outcomes in a tertiary referral center. METHODS: Information on complete uterine rupture between July 2010 and June 2022 was investigated retrospectively at a tertiary center. RESULTS: There were 42 cases of complete uterine rupture in 144 474 deliveries, with an incidence rate of 0.029%. Twenty-seven cases had a scarred uterus and 15 had an unscarred uterus; Rupture of the lower uterine segment was predominant in the scarred uterus, whereas rupture of the body of the uterus was predominant in the non-scarred uterus (P ≤ 0.001). Newborns with Apgar score of 7 or less at 1 min in the non-scarred uterus group was more than that in the scarred uterus group (P = 0.001). There were no significant differences in the history of gynecologic surgery, induction of labor, mode of delivery, clinical features, maternal outcomes, neonatal weight, preterm birth rate, 5-min Apgar score, or neonatal mortality between the two groups (P > 0.05). CONCLUSION: The clinical manifestations of uterine rupture are mainly abdominal pain, abnormal fetal heartbeat, or vaginal bleeding. Attention should also be paid to the history of previous uterine surgery. Strict prenatal management, early identification, and aggressive management can help improve maternal and child outcomes. Hysterectomy is not imperative.

Prenatal Detection and Conservative Management of Uterine Scar Dehiscence in Patient with Previous Uterine Rupture and Multiple Surgeries-A Case Report.

Uterine rupture is a rare and life-threatening condition. It usually occurs in patients with uterine scars (most commonly for a previous myomectomy or caesarean section), but it can also affect an unharmed uterus. This complication is more frequent in the third trimester and during delivery. There is not yet a recognised method of prediction of uterine rupture and the ultrasound features still need a consensus. In this article, we have reported a case of uterine dehiscence diagnosed by a pelvic ultrasound and magnetic resonance (MRI) at 24 weeks of gestation. The finding was confirmed intraoperatively at the caesarean section at 29 weeks of gestation. The 40-year-old patient has had a previous pregnancy complicated by uterine rupture at 22 weeks of gestation, following six previous abdominal surgeries for stage IV endometriosis, diffuse and nodular adenomyosis, and pelvic adhesion syndrome. The early detection of uterine dehiscence allowed us to prolong the pregnancy and perform a subsequent fertility-sparing surgery, reducing maternal and neonatal morbidity and mortality. Our case report proves that women with severe endometriosis/adenomyosis are at a high risk of uterine rupture and scar dehiscence. The antenatal ultrasound can describe a uterine dehiscence (even in asymptomatic patients) and prevent complications.

Trauma in pregnancy: A narrative review of the current literature.

INTRODUCTION: Trauma accounts for nearly half of all deaths of pregnant women. Pregnant women have distinct physiologic and anatomic characteristics which complicate their management following major trauma. OBJECTIVE: This paper comprises a narrative review of the most recent literature informing the management of pregnant trauma patients. DISCUSSION: The incidence of trauma during pregnancy is 6-8%. The focus of clinical assessment must be on the mother, starting with the primary survey. During airway management, clinicians should consider early intubation if necessary and utilize gastric tubes to minimize the risk of aspiration. Pregnant women experience progesterone-mediated hyperventilation, and normal PaCO2 levels may portend imminent respiratory failure. Clinicians should utilize left lateral tilt in hypotensive pregnant women to displace the uterus off the inferior vena cava. Ultrasonography is an attractive imaging modality for pregnant women which is specific for ruling in intraabdominal hemorrhage but not sufficiently sensitive to exclude this diagnosis. Clinicians should not hesitate to order computed tomography imaging in unstable patients if there is diagnostic ambiguity. Cardiotocographic monitoring simultaneously assesses uterine contractions and fetal heart rate and should last at least 4 h for pregnant women following even minor abdominal trauma if their fetus has achieved viable gestational age (approximately 24 weeks). In the event of cardiac arrest, peri-mortem cesarean section may improve outcomes for the mother and fetus alike. Unique specific complications include uterine rupture and placental abruption, which require emergent resuscitation and obstetrics consultation for definitive management. Emergency clinicians should maintain a low threshold for transfer to a tertiary care center given correlations between even isolated and relatively minor traumatic injuries with adverse fetal and maternal outcomes. CONCLUSIONS: Trauma is a common cause of morbidity and mortality in pregnant women. Emergency clinicians must understand the evaluation and management of pregnant trauma patients.

Vascular Ehlers-Danlos Syndrome: A Comprehensive Natural History Study in a Dutch National Cohort of 142 Patients.

BACKGROUND: Vascular Ehlers-Danlos syndrome (vEDS) is a rare connective tissue disorder with a high risk for arterial, bowel, and uterine rupture, caused by heterozygous pathogenic variants in COL3A1. The aim of this cohort study is to provide further insights into the natural history of vEDS and describe genotype-phenotype correlations in a Dutch multicenter cohort to optimize patient care and increase awareness of the disease. METHODS: Individuals with vEDS throughout the Netherlands were included. The phenotype was charted by retrospective analysis of molecular and clinical data, combined with a one-time physical examination. RESULTS: A total of 142 individuals (50% female) participated the study, including 46 index patients (32%). The overall median age at genetic diagnosis was 41.0 years. More than half of the index patients (54.3%) and relatives (53.1%) had a physical appearance highly suggestive of vEDS. In these individuals, major events were not more frequent (P=0.90), but occurred at a younger age (P=0.01). A major event occurred more often and at a younger age in men compared with women (P<0.001 and P=0.004, respectively). Aortic aneurysms (P=0.003) and pneumothoraces (P=0.029) were more frequent in men. Aortic dissection was more frequent in individuals with a COL3A1 variant in the first quarter of the collagen helical domain (P=0.03). CONCLUSIONS: Male sex, type and location of the COL3A1 variant, and physical appearance highly suggestive of vEDS are risk factors for the occurrence and early age of onset of major events. This national multicenter cohort study of Dutch individuals with vEDS provides a valuable basis for improving guidelines for the diagnosing, follow-up, and treatment of individuals with vEDS.

Spontaneous uterine rupture complicated by bilateral pulmonary emboli: A case report.

Spontaneous uterine rupture in unscarred uteri complicated by pulmonary emboli is a rare event with major maternal morbidity and mortality. This is a case of a 32-year-old woman, G1P0, at term, with no pertinent past medical/surgical history, who underwent an emergency cesarean delivery for failed induction of labor complicated by uterine rupture. Post-operatively, the patient was tachycardic and hypoxic. CT arteriogram revealed massive bilateral pulmonary emboli, and she was transferred for specialist care. An emergency pulmonary embolectomy and implantation of an extracorporeal right ventricular assist device were performed. Once the patient was clinically stable, an evaluation for thrombophilias and collagen disorders was done, and was positive for a variant of unknown significance in the ELN gene (c.205G > C). This case report highlights a potential connection between uterine ruptures, hemorrhage, and multiple, large pulmonary emboli. The authors propose a multidisciplinary discussion and evaluation to identify risk factors and biologic causes for these rare but life-threatening complications.

Clinical analysis of complete uterine rupture during pregnancy.

BACKGROUND: Uterine rupture in pregnant women can lead to serious adverse outcomes. This study aimed to explore the clinical characteristics, treatment, and prognosis of patients with complete uterine rupture. METHODS: Data from 33 cases of surgically confirmed complete uterine rupture at Chenzhou No.1 People's Hospital between January 2015 and December 2022 were analyzed retrospectively. RESULTS: In total, 31,555 pregnant women delivered in our hospital during the study period. Of these, approximately 1‰ (n = 33) had complete uterine rupture. The average gestational age at complete uterine rupture was 31+4 weeks (13+1-40+3 weeks), and the average bleeding volume was 1896.97 ml (200-6000 ml). Twenty-six patients (78.79%) had undergone more than two deliveries. Twenty-five women (75.76%) experienced uterine rupture after a cesarean section, two (6.06%) after fallopian tube surgery, one (3.03%) after laparoscopic cervical cerclage, and one (3.03%) after wedge resection of the uterine horn, and Fifteen women (45.45%) presented with uterine rupture at the original cesarean section incision scar. Thirteen patients (39.39%) were transferred to our hospital after their initial diagnosis. Seven patients (21.21%) had no obvious symptoms, and only four patients (12.12%) had typical persistent lower abdominal pain. There were 13 cases (39.39%, including eight cases ≥ 28 weeks old) of fetal death in utero and two cases (6.06%, both full term) of severe neonatal asphyxia. The rates of postpartum hemorrhage, blood transfusion, hysterectomy were 66.67%, 63.64%, and 21.21%. Maternal death occurred in one case (3.03%). CONCLUSIONS: The site of the uterine rupture was random, and was often located at the weakest point of the uterus. There is no effective means for detecting or predicting the weakest point of the uterus. Rapid recognition is key to the treatment of uterine rupture.

An Ominous Case of Uterine Rupture in an Unscarred Womb and Its Subsequent Management.

Uterine rupture is a rare but critical obstetric complication that demands a swift and decisive intervention to ensure the well-being of the mother and fetus. We present a case report detailing the surgical management of a bizarre uterine rupture in a multigravida female with two previous vaginal deliveries and a previously unscarred uterus. This case highlights the challenges of treating and diagnosing, particularly in the Indian setting, an antenatally unregistered patient with rare obstetrical complications. Emphasizing the clinical challenges faced and the multidisciplinary approach employed for optimal outcomes, this report underscores the importance of a high degree of suspicion, early diagnosis, timely intervention, and comprehensive intraoperative and postoperative care in addressing this rare obstetric catastrophic event. This article's main focus is multicentric, aiming to showcase the obstacles to maintaining low maternal mortality and morbidity, the presence of inadequate awareness in society, and the importance of multimodal treatment and planning.

Labor Induction in Women with Isolated Polyhydramnios at Term: A Multicenter Retrospective Cohort Analysis.

Background: With the increasing popularity of elective induction after 39 + 0 weeks, the question of whether induction of labor (IOL) is safe in women with isolated polyhydramnios has become more relevant. We aimed to evaluate the pregnancy outcomes associated with IOL among women with and without isolated polyhydramnios. Methods: This was a multicenter retrospective cohort that included women who underwent induction of labor at term. The study compared women who underwent IOL due to isolated polyhydramnios to low-risk women who underwent elective IOL due to gestational age only. The main outcome measure was a composite adverse maternal outcome, while the secondary outcomes included maternal and neonatal adverse pregnancy outcomes. Results: During the study period, 1004 women underwent IOL at term and met inclusion and exclusion criteria; 162 had isolated polyhydramnios, and 842 had a normal amount of amniotic fluid. Women who had isolated polyhydramnios had higher rates of the composite adverse maternal outcome (28.7% vs. 20.4%, p = 0.02), prolonged hospital stay, perineal tear grade 3/4, postpartum hemorrhage, and neonatal hypoglycemia. Multivariate analyses revealed that among women with IOL, polyhydramnios was significantly associated with adverse composite maternal outcome [aOR 1.98 (1.27-3.10), p < 0.01]. Conclusions: IOL in women with isolated polyhydramnios at term was associated with worse perinatal outcomes compared to low-risk women who underwent elective IOL. Our findings suggest that the management of women with polyhydramnios cannot be extrapolated from studies of low-risk populations and that clinical decision-making should take into account the individual patient's risk factors and preferences.

Evaluation of incision healing status after transverse uterine fundal incision for cesarean delivery and postoperative pregnancy: a ten-year single-center retrospective study.

BACKGROUND: Transverse uterine fundal incision (TUFI) is a beneficial procedure for mothers and babies at risk due to placenta previa-accreta, and has been implemented worldwide. However, the risk of uterine rupture during a subsequent pregnancy remains unclear. We therefore evaluated the TUFI wound scar to determine the approval criteria for pregnancy after this surgery. METHODS: Between April 2012 and August 2022, we performed TUFI on 150 women. Among 132 of the 150 women whose uteruses were preserved after TUFI, 84 women wished to conceive again. The wound healing status, scar thickness, and resumption of blood flow were evaluated in these women by magnetic resonance imaging (MRI) and sonohysterogram at 12 months postoperatively. Furthermore, TUFI scars were directly observed during the Cesarean sections in women who subsequently conceived. RESULTS: Twelve women were lost to follow-up and one conceived before the evaluation, therefore 71 cases were analyzed. MRI scans revealed that the "scar thickness", the thinnest part of the scar compared with the normal surrounding area, was ≥ 50% in all cases. The TUFI scars were enhanced in dynamic contrast-enhanced MRI except for four women. However, the scar thickness in these four patients was greater than 80%. Twenty-three of the 71 women conceived after TUFI and delivered live babies without notable problems until August 2022. Their MRI scans before pregnancy revealed scar thicknesses of 50-69% in two cases and ≥ 70% in the remaining 21 cases. And resumption of blood flow was confirmed in all patients except two cases whose scar thickness ≥ 90%. No evidence of scar healing failure was detected at subsequent Cesarean sections, but partial thinning was found in two patients whose scar thicknesses were 50-69%. In one woman who conceived seven months after TUFI and before the evaluation, uterine rupture occurred at 26 weeks of gestation. CONCLUSIONS: Certain criteria, including an appropriate suture method, delayed conception for at least 12 months, evaluation of the TUFI scar at 12 months postoperatively, and cautious postoperative management, must all be met in order to approve a post-TUFI pregnancy. Possible scar condition criteria for permitting a subsequent pregnancy could include the scar thickness being ≥ 70% of the surrounding area on MRI scans, at least partially resumed blood flow, and no abnormalities on the sonohysterogram. TRIAL REGISTRATION: Retrospectively registered.

Clinical analysis of incomplete rupture of the uterus secondary to previous cesarean section.

Uterine rupture is a rupture of the body or lower part of the uterus during pregnancy or delivery. Total of 98 cases with incomplete uterine rupture were classified as the incomplete uterine rupture group, 100 cases with a history of cesarean delivery without uterine rupture were classified as the non-ruptured uterus group, and controls were selected using a systematic sampling method. The maternal age ≥35 years were associated with 2.18 times higher odds of having an incomplete uterine rupture. The odd of having an incomplete uterine rupture was 3.744 times higher for a woman with delivery interval ≤36 months. Having pregnancy complication was associated with 3.961 times higher odds of having an incomplete uterine rupture. The neonatal weight was lighter in the incomplete uterine rupture group (P = 0.007). The number of preterm birth and transfer to the NICU were higher in the incomplete uterine rupture group (P ＜ 0.01). The operation time and the length of time in hospital were longer in the group with incomplete uterine rupture (P ＜ 0.01). Age ≥35 years, delivery interval ≤36 month, and pregnancy with complication were independent risk factors of incomplete rupture of the uterus secondary to previous cesarean section.
