RESUMO

BACKGROUND: Uncertain fetal head engagement represents 4% of obstetrical situations associated with an increased risk of postpartum hemorrhage, notably in cases of cesarean delivery and increased neonatal impairment owing to failed vaginal instrumental delivery. In this obstetrical condition, cesarean delivery is recommended, but vaginal delivery is possible in two-thirds of the cases. During the second stage of labor, the descent of the fetal head can be assessed by sonography, particularly by measuring the angle of progression. OBJECTIVE: To evaluate, after a prolonged second stage of labor, the impact of measuring the angle of progression in addition to a digital examination on cesarean delivery rates when fetal head engagement remains uncertain. STUDY DESIGN: This open multicenter randomized pragmatic trial included women at term with a singleton cephalic fetus in a clinical occiput anterior position after a prolonged 2-hour second stage of labor with uncertain fetal head engagement. After inclusion in the study, an independent investigator performed ultrasound systematically to confirm the occiput anterior position and measured the angle of progression at the climax of Valsalva pushing. This operator did not participate in labor management. In the study group but not in the control group, the angle of progression was communicated to the obstetrician in charge of labor management. Obstetricians were encouraged to attempt vaginal birth if the angle of progression was >120°. The primary outcome was the cesarean delivery rate. Secondary outcomes were operative delivery rate (cesarean delivery and operative vaginal delivery), maternal complications (third and fourth-degree perineal tears, failed vaginal instrumental delivery, postpartum hemorrhage, hysterectomy), and neonatal outcomes (Apgar score <5 at 10 minutes, umbilical arterial pH <7.10, neonatal wounds, neonatal intensive care unit admission). RESULTS: A total of 45 women were included in the study. Occiput anterior position was confirmed in 33 women: 16 in the study group and 17 in the control group. Women's characteristics at baseline were similar between the groups. The median (range) angles of progression were similar: 138.4° (15) and 140.3° (16.9) in the study and control group, respectively. Cesarean delivery rates were 12.5% in the study group and 41.1% in the control group (P=.06). Secondary outcomes were similar between the 2 groups. No failed vaginal instrumental delivery was reported. CONCLUSION: Measurement of the angle of progression in addition to digital examination when fetal head engagement remained uncertain showed promising results in decreasing cesarean delivery rates. A larger multicenter randomized controlled trial is needed to confirm these results.

RESUMO

BACKGROUND: Persistent occiput posterior and occiput transverse positions are the most common malpositions of the fetal head during labor and are associated with prolonged second stage of labor, cesarean deliveries, instrumental deliveries, severe perineal tears, postpartum hemorrhage, and chorioamnionitis. Manual rotation is one of several strategies described to deal with these malpositions. OBJECTIVE: This study aimed to determine if the trial of prophylactic manual rotation at the early second stage of labor is associated with a decrease in operative deliveries (instrumental and/or cesarean deliveries). STUDY DESIGN: We conducted a multicenter, open-label, randomized controlled trial in 4 French hospitals. Women with singleton term pregnancy and occiput posterior or occiput transverse position confirmed by ultrasound at the early second stage of labor and with epidural analgesia were eligible. Women were randomly assigned (1:1) to either undergo a trial of prophylactic manual rotation of occiput posterior or occiput transverse position (intervention group) or no trial of prophylactic manual rotation (standard group). The primary outcome was operative delivery (instrumental and/or cesarean deliveries). The secondary outcomes were length of the second stage of labor, maternal complications (postpartum hemorrhage, operative complications during cesarean delivery, episiotomy and perineal tears), and neonatal complications (Apgar score of <5 at 10 minutes, arterial umbilical pH of <7.10, neonatal injuries, neonatal intensive care unit admission). The main analysis was focused on intention-to-treat analysis. RESULTS: From December 2015 to December 2019, a total of 257 women (mean age, 30.4 years; mean gestational age, 40.1 weeks) were randomized: 126 were assigned to the intervention group and 131 were assigned to the standard group. Operative delivery was significantly less frequent in the intervention group compared with the standard group (29.4% [37 of 126] vs 41.2% [54 of 131]; P=.047; differential [intervention-standard] [95% confidence interval] = -11.8 [-15.7 to -7.9]; unadjusted odds ratio [95% confidence interval] = 0.593 [0.353-0.995]). Women in the intervention group were more likely to have a significantly shorter second stage of labor. CONCLUSION: Trial of prophylactic manual rotation of occiput posterior or occiput transverse positions during the early second stage of labor was statistically associated with a reduced risk of operative delivery. This maneuver could be a safe strategy to prevention operative delivery.

RESUMO

The aim of this study was to identify specific unusual prenatal ultrasound (US) patterns of the adrenal gland and to propose a systematic approach for diagnosis. Six fetuses with unusual aspects of one or both adrenal glands, detected during routine prenatal US screening, were evaluated. Prenatal and postnatal management are described. A checklist of US features was created to perform a detailed analysis of adrenal lesions and guide prenatal management; this includes the time of appearance, location, growth, vascularization, structure, and presence of findings suggestive of malignancy.

RESUMO

OBJECTIVE: To study whether history of cesarean delivery for arrest of descent (failure of fetal head engagement or unsuccessful instrumental delivery), is a factor of unsuccessful vaginal birth after cesarean delivery. METHODS: Multicenter prospective study of patients undergoing TOL after previous caesarean delivery between May 2012 and May 2013 in 6 maternities. Univariate statistical analysis was performed depending of previous cesarean delivery indication. Multivariate analysis was used to determine independent association between these factors and TOLAC success. RESULTS: Four hundred and eighty women with previous cesarean delivery were included and separated into two groups: the study group was composed of patients with history of CD for arrest of descent (failure of fetal head engagement or unsuccessful instrumental delivery) (n=31); control group included all other indications for CD (n=449). Overall, of the 480 women included in the study, 71.2 % underwent a TOL for a subsequent delivery (n=342): 68 % in the study group (n=21) vs 71.5 % in the control group (n=321). Vaginal birth after cesarean (VBAC) was obtained in 66.6 % vs 61% in the study and control group respectively (p=0.656). Univariate analysis of factors that may influence the success rate of (VBAC) did not show any difference between the two groups. Multivariate analysis showed that VBAC was only significantly associated with history of vaginal delivery subsequent to prior CD for arrest of descent. CONCLUSION: This study reassures us in our clinical practice allowing TOL in cases of history of CD for fetal head engagement failure or instrumental delivery failure in the second stage of labor.

RESUMO

Placental chorioangioma is a limited non trophoblastic vascular tumour that may causes fetal complications as well as post-natal ones. We reported in here the first case of an in utero embolization of chorioangioma diagnosed at 22 W G with a post-natal diagnosis of neonatal multifocal hemangioma with a good outcome. The chorioangioma was embolized using GLUBRAN 2 ® (cyanolacrylate) a biologic surgical glue at 26 W G. Premature rupture of membrane occurred at 28 W G. A cesarean section at 32 W G was performed for retro placental hematoma. The neonate was 1400 g healthy girl with an anemia (hemoglobin 9.7 g/dl). After one month of life, the child met a neonatal multifocal hemangioma (skin and liver were involved) with superficial erosion of skin hemangiomas that required post-natal transfusions. We propose a literature review related to the various technics of in utero treatment of placental chorioangioma and the links with neonatal multifocal hemangiomatosis as well. The girl is now 7 year old and has a normal neurodevelopmental outcome.

RESUMO

Postpartum haemorrhage (PPH) is defined as blood loss ≥500mL after delivery and severe PPH as blood loss ≥1000mL, regardless of the route of delivery (professional consensus). The preventive administration of uterotonic agents just after delivery is effective in reducing the incidence of PPH and its systematic use is recommended, regardless of the route of delivery (Grade A). Oxytocin is the first-line prophylactic drug, regardless of the route of delivery (Grade A); a slowly dose of 5 or 10 IU can be administered (Grade A) either IV or IM (professional consensus). After vaginal delivery, routine cord drainage (Grade B), controlled cord traction (Grade A), uterine massage (Grade A), and routine bladder voiding (professional consensus) are not systematically recommended for PPH prevention. After caesarean delivery, placental delivery by controlled cord traction is recommended (grade B). The routine use of a collector bag to assess postpartum blood loss at vaginal delivery is not systematically recommended (Grade B), since the incidence of severe PPH is not affected by this intervention. In cases of overt PPH after vaginal delivery, placement of a blood collection bag is recommended (professional consensus). The initial treatment of PPH consists in a manual uterine examination, together with antibiotic prophylaxis, careful visual assessment of the lower genital tract, a uterine massage, and the administration of 5-10 IU oxytocin injected slowly IV or IM, followed by a maintenance infusion not to exceed a cumulative dose of 40IU (professional consensus). If oxytocin fails to control the bleeding, the administration of sulprostone is recommended within 30minutes of the PPH diagnosis (Grade C). Intrauterine balloon tamponade can be performed if sulprostone fails and before recourse to either surgery or interventional radiology (professional consensus). Fluid resuscitation is recommended for PPH persistent after first line uterotonics, or if clinical signs of severity (Grade B). The objective of RBC transfusion is to maintain a haemoglobin concentration (Hb) >8g/dL. During active haemorrhaging, it is desirable to maintain a fibrinogen level ≥2g/L (professional consensus). RBC, fibrinogen and fresh frozen plasma (FFP) may be administered without awaiting laboratory results (professional consensus). Tranexamic acid may be used at a dose of 1 g, renewable once if ineffective the first time in the treatment of PPH when bleeding persists after sulprostone administration (professional consensus), even though its clinical value has not yet been demonstrated in obstetric settings. It is recommended to prevent and treat hypothermia in women with PPH by warming infusion solutions and blood products and by active skin warming (Grade C). Oxygen administration is recommended in women with severe PPH (professional consensus). If PPH is not controlled by pharmacological treatments and possibly intra-uterine balloon, invasive treatments by arterial embolization or surgery are recommended (Grade C). No technique for conservative surgery is favoured over any other (professional consensus). Hospital-to-hospital transfer of a woman with a PPH for embolization is possible once hemoperitoneum is ruled out and if the patient's hemodynamic condition so allows (professional consensus).

RESUMO

OBJECTIVE: To identify antenatal events associated with emergency caesarean sections in women presenting with antepartum bleeding and placenta praevia and to establish a score to predict the risk of emergency caesarean after a first bleeding episode has resolved. STUDY DESIGN: This retrospective multicentre study included 250 women presenting with antepartum bleeding and placenta praevia from 20 weeks of gestation until term in three maternity units. The score was constructed from data from 163 women after identification of antenatal risk factors associated with emergency caesareans for profuse bleeding due to placenta praevia. It was validated on a second independent cohort of 87 women. RESULTS: Three variables were significantly associated with emergency caesareans: major or complete praevia, defined as complete or partial praevia (OR=33.15 (95% CI 4.3-257); p=0.001), occurrence of 3 or more episodes of antepartum of uterine bleeding (OR=2.53 (95% CI 1.1-5.86); p=0.03), and a first (sentinel) bleeding episode before 29 weeks of gestation (OR=2.64 (95% CI 1.17-5.98); p=0.02). A fourth variable, moderate or severe antepartum uterine bleeding, was significantly associated with emergency caesareans in the univariate but not the multivariate analysis (p=0.006). These four variables were incorporated into a weighted scoring system that included major praevia (4 points), three or more episodes of antepartum bleeding (3), first bleeding episode before 29 weeks of gestation (3), and bleeding episode estimated as moderate or severe (1). A score ≥6/11 had a sensitivity of 83% and a specificity of 65% for predicting an emergency caesarean in the score development group and 95% and 62% in the validation group. CONCLUSION: A scoring system for placenta praevia with previous bleeding events, based on intensity, gestational age at sentinel bleed (before 29 weeks), number of bleeding episodes (≥3) and type of praevia (major) might be helpful to guide obstetric management and especially to determine the need for admission.

RESUMO

OBJECTIVE: To study cervix elastography measurement and its relation with pregnancy outcome. DESIGN: A two year prospective longitudinal study evaluated cervical elasticity by HI-RTE (Hitachi real-time tissue elastography) imaging during three trimesters of pregnancy. The main outcome measure was elastography index the cervical elastogram color-coded. RESULTS: Three hundred eighty seven measurements were realized among 72 pregnant women prospectively enrolled. In the first trimester, the elasticity index was significantly lower in women who subsequently had unfavorable outcome than in women who delivered at term (respectively, EI=0.51 (±0.04) and 0.59 (±0.02); P=0.037). The negative predictive value of posterior lip color (blue, blue-green=hard cervix) was high NPV=83.8 95% CI [68.8-92.4] in the first trimester (SE=64.7 95% CI [41.3-82.7]; SP=60.8 95% CI [47.1-72.9]; VPP=35.5 95% CI [21.1-53.1]). A first-trimester elasticity index threshold value ≤0.38 had a specificity of 98.0% and a NPV of 80.9% (Se 29.4%, PPV 83.3%). This index value, when combined with a cervical length less than or equal to 36mm, increased the risk of adverse outcome (HR 8.87 95% CI [3.22-23.7]). CONCLUSIONS: Cervical elastography index is associated with unfavorable obstetrical outcomes, independently of cervical length. The study was registered in ClinicalTrials.gov under Identifier number NCT01032564.

RESUMO

The major histocompatibility complex class I related chain (MIC) is a stress-inducible protein modulating the function of immune natural killer (NK) cells, a major leukocyte subset involved in proper trophoblast invasion and spiral artery remodeling. Aim of the study was to evaluate whether upregulation of soluble MIC (sMIC) may reflect immune disorders associated to vascular pregnancy diseases (VPD). sMIC was more frequently detected in the plasma of women with a diagnostic of VPD (32%) than in normal term-matched pregnancies (1.6%, P < 0.0001), with highest prevalence in intrauterine fetal death (IUDF, 44%) and vascular intrauterine growth restriction (IUGR, 39%). sMIC levels were higher in preeclampsia (PE) than in IUFD (P < 0.01) and vascular IUGR (P < 0.05). sMIC detection was associated with bilateral early diastolic uterine notches (P = 0.037), thrombocytopenia (P = 0.03), and high proteinuria (P = 0.03) in PE and with the vascular etiology of IUGR (P = 0.0038). Incubation of sMIC-positive PE plasma resulted in downregulation of NKG2D expression and NK cell-mediated IFN-γ production in vitro. Our work thus suggests that detection of sMIC molecule in maternal plasma may constitute a hallmark of altered maternal immune functions that contributes to vascular disorders that complicate pregnancy, notably by impairing NK-cell mediated production of IFN-γ, an essential cytokine favoring vascular modeling.

RESUMO

OBJECTIVE: To evaluate short and medium term outcomes of children born of monochorionic pregnancies complicated by twin-twin transfusion syndrome treated by fetoscopic laser surgery. METHODS: This was a retrospective observational study performed between May 2007 and 2012. Neonatal data was from 45 patients under 5 years of age. The prospective observational study was of the neurologic outcome of these children using the Ages and Stages Questionnaire (ASQ), 2nd edition, French version, at up to 5 years of age. RESULTS: Neurologic assessment at discharge from maternity unit was normal for 41 infants (93.2%). Logistic regression suggested that the risk of neurosensory sequelae was significantly related to the status of donor [odds ratio=4.62 (1.18; 18.0)] and significantly preterm birth <32 weeks of gestation [odds ratio=5.50 (1.38; 21.9)]. Eleven questionnaires were considered abnormal (31.1%). Two children presented a severe neurologic abnormality (5.7%). There was no significant correlation between any area of the questionnaire and status at birth (donor or recipient). CONCLUSIONS: The data from our cohort, particularly as regards neurologic outcome, were satisfactory and concordant with previously published results. The use of the ASQ as a screening tool for neurologic outcome in children is original, which allowed in our cohort to highlight early neurological disorders.

RESUMO

The primary cause of uterine scars is a previous cesarean. In women with a previous cesarean, the risks of maternal complications are rare and similar after a trial of labor after cesarean (TOLAC) and after an elective repeat cesarean delivery (ERCD), but the risk of uterine rupture is higher with TOLAC (level of evidence [LE]2). Maternal morbidity in women with previous cesareans is higher when TOLAC fails than when it leads to successful vaginal delivery (LE2). Although maternal morbidity increases progressively with the number of ERCD, maternal morbidity of TOLAC decreases with the number of successful previous TOLAC (LE2). The risk-benefit ratio considering the risks of short- and long-term maternal complications is favorable to TOLAC in most cases (LE3). Globally, neonatal complications are rare regardless of the mode of delivery for women with previous cesareans. The risks of fetal, perinatal, and neonatal mortality during TOLAC are low. Nonetheless, these risks are significantly higher than those associated with ERCD (LE2). The risks of mask ventilation, intubation for meconium-stained amniotic fluid, and neonatal sepsis all increase in TOLAC (LE2). The risk of transient respiratory distress increases in ERCD (LE2). To reduce this risk, and except in particular situations, ERCD must not be performed before 39 weeks (grade B). TOLAC is possible for women with a previous cesarean before 37 weeks, with 2 previous cesareans, with a uterine malformation, a low vertical incision or an unknown incision, with a myomectomy, postpartum fever, an interval of less than 6 months between the last cesarean delivery and the conception of the following pregnancy, if the obstetric conditions are favorable (professional consensus). ERCD is recommended in women with a scar in the uterine body (grade B) and a history of 3 or more cesareans (professional consensus). Ultrasound assessment of the risk of uterine rupture in women with uterine scars has not been shown to have any clinical utility and is therefore not recommended during pregnancy to help decide the mode of delivery (professional consensus). Use of X-ray pelvimetry to decide about TOLAC is associated with an increase in the repeat cesarean rate without any reduction in the rate of uterine rupture (LE2). It is unnecessary for deciding mode of delivery and for managing labor during TOLAC (grade C). TOLAC should be encouraged for women with a previous vaginal delivery either before or after the cesarean, a favorable Bishop score or spontaneous labor, and for preterm births (grade C). For women with a fetus with an estimated weight of more than 4500 g, especially in the absence of a previous vaginal delivery and those with supermorbid obesity (BMI>50), ERCD must be planned from the outset (grade C). For all of the other clinical situations envisioned (maternal age>35 years, diabetes, morbid obesity, prolonged pregnancy, breech presentation and twin pregnancy), TOLAC is possible but the available data do not allow specific guidelines about the choice of mode of delivery, in view of the low levels of proof (grade C). The decision about planned mode of delivery must be shared by the patient and her physician and made by the 8th month, taking into account the individual risk factors for TOLAC failure and uterine rupture (professional consensus). TOLAC is the preferred choice for women who do not have several risk factors (professional consensus). The availability onsite of an obstetrician and anesthetist must be pointed out to the patient. If the woman continues to prefer a repeat cesarean after adequate information and time to think about it, her preference should be honored (professional consensus). Labor should be induced in woman with a previous cesarean only for medical indications (professional consensus). Induction of labor increases the risk of uterine rupture, which can be estimated at 1% if oxytocin is used and 2% with vaginal prostaglandins (LE2). Mechanical methods of induction have not been studied sufficiently. Misoprostol appears to increase the risk of uterine rupture strongly (LE4). Based on the information now available, its use is not recommended (professional consensus). Routine use of internal tocodynamometry does not prevent uterine rupture (professional consensus). The increased risk of uterine rupture associated with oxytocin use is dose-dependent (LE3). In the active phase, it is recommended that the total duration of failure to progress should not exceed 3h; at that point, a cesarean should be performed (professional consensus). Epidural analgesia must be encouraged. The simple existence of a uterine scar is not an indication for a routine manual uterine examination after VBAC (grade C).

RESUMO

The duration of pregnancy varies between 40(+0) and 41(+3) weeks. Conventionally, and essentially arbitrarily, a pregnancy is considered to be "prolonged" after 41(+0) weeks, but the infant is not considered "post-term" until 42(+0) weeks (Professional consensus). A term birth thus occurs during the period from 37(+0) to 41(+6) weeks. In France, prolonged pregnancies (≥41(+0)weeks) involve 15-20% of pregnant women, and post-term pregnancies (≥42(+0) weeks) approximately 1%. The frequency of post-term pregnancies is very heterogeneous: in Europe and the United States, it ranges from 0.5% to 10% according to country. In prolonged pregnancies, the cesarean section rate-especially the emergency cesarean rate-is multiplied by approximately 1.5 (grade B). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly, from 0.7‰ to 5.8‰. Meconium aspiration syndrome is responsible for substantial morbidity and mortality, and its incidence increases regularly between 38(+0) and 42(+6) weeks, from 0.24‰ to 1.42‰ (grade B). Similarly, the risks of neonatal acidosis (grade B), 5-min Apgar scores less than 7 (grade B) and admissions to neonatal intensive care (grade B) increase progressively between 38(+0) and 42(+6) weeks. These risks appear to double for post-term growth-restricted newborns (grade C). Ultrasound dating of the pregnancy makes it possible to reduce the risk that it will be incorrectly considered prolonged and that labor will therefore be induced unnecessarily. To harmonize practices, if the crown-rump length (CRL) is correctly measured (this measurement should be taken between 11(+0) and 13(+6) weeks, when CRL should measure from 45 to 84mm), ultrasound dating based on it should be used to determine the official date pregnancy began, regardless of its difference from the date assumed by the patient or estimated based on the date of the last menstrual period. This rule does not apply to pregnancies by IVF, for which the date pregnancy began is defined by the date of oocyte retrieval (Professional consensus). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly and there is no threshold at which a clear increase in perinatal mortality becomes visible. Fetal monitoring by cardiotocography (CTG) that begins at 41(+0) weeks would cover approximately 20% of women and reduce perinatal morbidity compared with monitoring that begins at 42(+0) weeks (grade C). The frequency recommended for this monitoring ranges between two and three times a week (Professional consensus). For ultrasonography assessment, measurement of the largest fluid pocket is recommended, because measurement of the amniotic fluid index (that is, the sum of the four quadrants) is accompanied by more diagnoses of oligohydramnios, inductions of labor, and cesareans for fetal distress without any improvement in neonatal prognosis (grade A). The practice of assessing the Manning biophysical score increases the number of diagnoses of oligohydramnios and fetal heart rage (FHR) abnormalities and generates an increase in the rates of inductions and cesareans without improving neonatal prognosis. The use of this biophysical score in monitoring prolonged pregnancies is therefore not recommended (grade B). In the absence of a specific disorder, induction of labor can be proposed in patients between 41(+0) and 42(+6) weeks (grade B). Nonetheless, the choice of prolongation beyond above 42(+0) weeks appears to involve an increase in fetal risk, which must be explained to the patient and balanced against the potential disadvantages of induction (Professional consensus). Stripping the membranes can reduce the duration of pregnancy by increasing the number of patients going into labor spontaneously during the week afterward (grade B). Compared to an expectant approach, it does not increase the cesarean section rate (grade A). It reduces recourse to induction by 41% at 41(+0) weeks and by 72% at 42(+0) weeks (grade B), without increasing the risk of either membrane rupture or maternal or neonatal infection (grade B). Used as a tampon or vaginal gel, prostaglandins E2 (PGE2) are an effective method of inducing labor (grade A). They can be used to induce labor successfully, regardless of cervical ripeness (grade A). If misoprostol is chosen, the lowest dose is to be preferred, starting with a vaginal dose of 25µg every 3-6h (grade A). For misoprostol, more powerful studies remain necessary for better defining the doses, routes of administration, tolerance and indications. Misoprostol at any dose is contraindicated in women with uterine scars (grade B). Placement of an intracervical Foley catheter is an effective mechanical means of inducing labor, with less uterine hyperstimulation than prostaglandins and no increase in the cesarean section rate (grade A). Nonetheless, as the risk of infection might be increased, this technique requires more robust evaluation before entering general practice (grade B). In cases of meconium-stained amniotic fluid, pharyngeal aspiration before delivery of the shoulders is not recommended (grade A). The team managing a post-term newborn with meconium-stained amniotic fluid at birth must know how to perform intubation and, if the intubation is not helpful, endotracheal aspiration (grade C) and ventilation with a mask. Routine endotracheal intubation of a vigorous newborn is not recommended (grade A).

RESUMO

OBJECTIVE: To evaluate the circumstances associated with the diagnosis of Mullerian anomalies in adults. DESIGN: Retrospective observational study. SETTING: University hospital. PATIENT(S): All patients with Mullerian anomalies referred for evaluation. INTERVENTION(S): All patients underwent radiologic and operative diagnostic workup using ultrasonography, or ultrasonography and hysteroscopy, and in some cases laparoscopy. MAIN OUTCOME MEASURE(S): Clinical symptoms and radiologic investigations leading to the diagnosis. Mode and number of investigations before the diagnosis, and the time since the initial symptoms to the final diagnosis. RESULT(S): One hundred ten patients were diagnosed with Mullerian anomalies: 73 septate uteri, 20 bicornuate uteri, 10 uterine hypoplasia, 4 unicornuate uteri, and 3 with Mayer- Mayer-Rokitansy-Küster-Hauser syndrome. The circumstances leading to the diagnosis were infertility (33.6%), repeat miscarriage (18.2%), ultrasonography during pregnancy (12.7%), pregnancy complications during last trimester (11%), abnormal examination (8.2%), and miscellaneous causes (16.3%). Up 50% of patients complained of gynecologic signs before the appropriate diagnosis. Radiologic diagnosis required two complementary imaging techniques in 62% of patients and more than two in 28%. The correct diagnosis was established in only 40% of cases before hospitalization. Most of the anomalies were initially diagnosed at hysterosalpingography and ultrasonography. The mean time between the first imaging examination and the diagnosis in a specialized department was 6.7 (+/-7.1) months. CONCLUSION(S): The diagnosis of Mullerian anomalies in adults is often made at the time of conception and obstetric complications. There is a tendency toward the use of multiple imaging techniques and this delayed the diagnosis.
