Placenta Pathology From Term Born Neonates With Normal or Adverse Outcome.

BACKGROUND: The incidence of umbilical cord or placental parenchyma abnormalities associated with mortality or morbidity of term infants is lacking. METHODS: Placentas of 55 antepartum stillbirths (APD), 21 intrapartum stillbirths (IPD), 12 neonatal deaths (ND), and 80 admissions to a level 3 neonatal intensive care unit (NS) were studied and compared with 439 placentas from neonates from normal term pregnancies and normal outcome after vaginal delivery (NPVD) and with 105 placentas after an elective caesarian sections (NPEC). RESULTS: NPVD and NPEC placentas showed no or one abnormality in 70% and placentas from stillbirth showed two or more abnormalities in 80% of cases. APD placentas more frequently had a low weight and less formation of terminal villi. Hypercoiling was more often present in all study groups. Severe chronic villitis was almost exclusively present in APD placentas. Chorioamnionitis was significantly more frequent in APD, IPD and NS placentas and funisitis was more often observed in IPD and NS placentas. CONCLUSION: Multiple placental abnormalities are significantly more frequent in placentas from term neonates with severe perinatal morbidity and mortality. These placental abnormalities are thought to be associated with disturbed oxygen transfer or with inflammation.

Influenza virus infection in pregnancy: a review.

BACKGROUND: Influenza virus infection is very common and a significant cause of morbidity and mortality in specific populations like pregnant women. Following the 2009 pandemic, several reports on the effects of influenza virus infection on maternal health and pregnancy outcome have been published. Also the safety and efficacy of antiviral treatment and vaccination of pregnant women have been studied. In this review, we have analyzed and summarized these data. OBJECTIVE: To provide information on the influence of influenza virus infection during pregnancy on maternal health and pregnancy outcome and on the effect of treatment and vaccination. DATA SOURCES: We have searched Medline, Embase and the Cochrane Library. We used influenza, influenz*, pregnancy and pregnan* as search terms. STUDY SELECTION: In total, 294 reports were reviewed and judged according to the STROBE guidelines or CONSORT statement. In all, 100 studies, published between 1961 and 2015, were included. RESULTS: Compared to the general population, pregnant women are more often hospitalized and admitted to an intensive care unit due to influenza virus infection. For hospitalized patients, increased rates of preterm birth and fetal/neonatal death are reported. Early treatment with oseltamivir is associated with a reduced risk of severe disease. Vaccination of pregnant women is safe and reduces maternal and neonatal morbidity. CONCLUSIONS: There is level 2b evidence that maternal health and pregnancy outcome can be severely affected by influenza virus infection. Antiviral treatment may diminish these effects and vaccination protects pregnant women and neonates from infection (level of evidence 2b and 1b, respectively).

Prediction of preterm birth in multiple pregnancies: development of a multivariable model including cervical length measurement at 16 to 21 weeks' gestation.

OBJECTIVE: To develop a multivariable prognostic model for the risk of preterm delivery in women with multiple pregnancy that includes cervical length measurement at 16 to 21 weeks' gestation and other variables. METHODS: We used data from a previous randomized trial. We assessed the association between maternal and pregnancy characteristics including cervical length measurement at 16 to 21 weeks' gestation and time to delivery using multivariable Cox regression modelling. Performance of the final model was assessed for the outcomes of preterm and very preterm delivery using calibration and discrimination measures. RESULTS: We studied 507 women, of whom 270 (53%) delivered < 37 weeks (preterm) and 66 (13%) < 32 weeks (very preterm). Women with cervical length < 30 mm delivered more often preterm (hazard ratio 1.9; 95% CI 0.7 to 4.8). Other independently contributing predictors were previous preterm delivery, monochorionicity, smoking, educational level, and triplet pregnancy. Prediction models for preterm and very preterm delivery had a c-index of 0.68 (95% CI 0.63 to 0.72) and 0.68 (95% CI 0.62 to 0.75), respectively, and showed good calibration. CONCLUSION: In women with a multiple pregnancy, the risk of preterm delivery can be assessed with a multivariable model incorporating cervical length and other predictors.

Objectif : Élaborer un modèle pronostique multivarié (comportant la mesure de la longueur cervicale à 16 - 21 semaines de gestation et d'autres variables) pour ce qui est du risque d'accouchement préterme chez les femmes connaissant une grossesse multiple. Méthodes : Nous avons utilisé les données issues d'un essai randomisé précédent. Nous avons évalué l'association entre les caractéristiques maternelles et de grossesse (dont la mesure de la longueur cervicale à 16 - 21 semaines de gestation et le délai avant l'accouchement) au moyen du modèle de régression multivariée de Cox. Le rendement du modèle final a été évalué en fonction de critères d'évaluation traitant du moment de l'accouchement (préterme et très préterme) au moyen de mesures d'étalonnage et de discrimination. Résultats : Nous avons étudié 507 femmes, dont 270 (53 %) ont accouché < 37 semaines (préterme) et 66 (13 %) < 32 semaines (très préterme). Les femmes qui présentaient une longueur cervicale < 30 mm ont plus souvent connu un accouchement préterme (densité de l'incidence, 1,9; IC à 95 %, 0,7 - 4,8). Parmi les autres facteurs prédictifs indépendants, on trouvait les antécédents d'accouchement préterme, la monochorionicité, le tabagisme, le niveau de scolarité et la présence d'une grossesse triple. Les modèles prédictifs pour ce qui est des accouchements préterme et très préterme comptaient un indice C de 0,68 (IC à 95 %, 0,63 - 0,72) et de 0,68 (IC à 95 %, 0,62 - 0,75), respectivement, et présentaient un bon étalonnage. Conclusion : Chez les femmes qui connaissent une grossesse multiple, le risque d'accouchement préterme peut être évalué au moyen d'un modèle multivarié comportant la mesure de la longueur cervicale et d'autres facteurs prédictifs. 

High rate of chronic villitis in placentas of pregnancies complicated by influenza A/H1N1 infection.

INTRODUCTION: Pandemic influenza A/H1N1 infection during pregnancy has a negative impact on several aspects of pregnancy outcome. As yet, no elucidating mechanism has been revealed for these effects. We investigated whether placentas of pregnancies complicated by 2009 influenza A/H1N1 infection demonstrated an increased rate of chronic villitis and whether this villitis was caused by influenza virus. METHODS: We performed a cohort study on 145 pregnant outpatients during the 2009-2010 influenza A H1N1 pandemic. The placentas of patients with influenza infection were examined for histologic signs of chronic villitis. In case of villitis, polymerase chain reaction (PCR) on influenza virus was performed on placental tissue. RESULTS: 29 patients had influenza infection. Placentas of 15 of these patients were collected and examined. In 7 cases (47%) chronic villitis was detected. Placental weight and birth weight of the neonates did not differ between cases with and without chronic villitis. In all cases PCR was negative for influenza. CONCLUSION: In our series, chronic villitis was present in a high proportion of placentas of pregnancies complicated by 2009 influenza A/H1N1 infection. We could not demonstrate the presence of influenza virus in placental tissue.

Substandard care in delivery-related asphyxia among term infants: prospective cohort study.

OBJECTIVE: To assess substandard care factors in the case of delivery-related asphyxia. DESIGN: Prospective cohort study. SETTING: Catchment area of the Neonatal Intensive Care Unit (NICU) of the University Medical Center Utrecht; a region in the middle of the Netherlands covering 13% of the Dutch population. POPULATION: Term infants, without congenital malformations, who died intrapartum or were admitted to the Neonatal Intensive Care Unit due to asphyxia. METHODS: During a two-year period, cases were prospectively collected and audited by an expert panel. MAIN OUTCOME MEASURES: Substandard care factors. RESULTS: 37 735 term infants without congenital malformations were born. There were 19 intrapartum deaths, and 89 NICU admissions of which 12 neonates died. In 63 (58%) cases a substandard care factor was identified that was possibly (n= 47, 43%) or probably (n= 16, 15%) related to perinatal death or NICU admission. In primary care, substandard care factors were mainly the low frequency of examination during labor and delay in referral to secondary care. In secondary care, misinterpretation of cardiotocography and failure to respond adequately to clinical signs of fetal distress were the most common substandard care factors. CONCLUSIONS: Substandard care is present in a substantial number of cases with delivery-related asphyxia resulting in perinatal death or NICU admission. Improving the organization of obstetric care in the Netherlands as well as training of obstetric caregivers might reduce adverse outcomes.

Reproductive outcome after early-onset pre-eclampsia.

BACKGROUND: Early-onset pre-eclampsia is an important cause of maternal and neonatal morbidity and mortality and is believed to have a significant impact on future maternal physical and psychological health. However, structured follow-up data of women with a history of early-onset pre-eclampsia are lacking. This study aims to present comprehensive data of a large cohort of women with a history of early-onset pre-eclampsia with respect to future reproductive health, family planning and subsequent pregnancy rates. METHODS: A tertiary referral cohort of 304 women entered the follow-up study at 6-12 months after their first delivery. Detailed data on maternal and neonatal outcomes, family planning and subsequent pregnancies were recorded. In addition, data on perspectives, major concerns and decision-making of women who had not achieved a second pregnancy were collected by questionnaire and structured interviews. Data were compared with a population of 268 low-risk primiparous women with an uncomplicated delivery. RESULTS: At a mean of 5.5 years after first delivery, 65.8% of women with a history of early-onset pre-eclampsia had achieved a second pregnancy compared with 77.6% of healthy controls. At follow-up, 19.1% of women with a history of early-onset pre-eclampsia had an active wish to become pregnant, whereas 15.1% of women did not wish to achieve a future pregnancy. In the latter group, decision-making was most commonly influenced by fear of recurrent disease (33%) and fear of delivering another premature child (33%) among others reasons, e.g. post-partum counseling and concerns of the partner. CONCLUSIONS: The majority of women with a history of early-onset pre-eclampsia achieve or wish to achieve a second pregnancy within a few years of their delivery. Nonetheless, first pregnancy early-onset pre-eclampsia appears to have a significant impact on future reproductive health and decision-making, emphasizing the importance of careful post-partum counseling.

Substandard care in antepartum term stillbirths: prospective cohort study.

OBJECTIVE: To assess substandard care factors in antepartum stillbirths at term. Design. Prospective cohort study. SETTING: A region in the middle of the Netherlands covering 13% of the Dutch population. POPULATION: Antepartum stillbirths (≥ 37 weeks) without congenital malformations. METHODS: During a two-year period, all antepartum term stillbirths were prospectively collected and audited by an expert panel. MAIN OUTCOME MEASURES: Substandard care factors. RESULTS: During the study period, 37 735 normally formed infants were delivered ≥ 37 weeks of gestation. There were 60 antepartum stillbirths (1.59 per 1,000, 95%CI 1.19-1.99). Most stillbirths occurred during apparently uncomplicated pregnancies. Twenty-one infants (35%) were small-for-gestational age but growth restriction was only suspected in 10 (47.6%) of these cases. Substandard care factors were identified in 21 (35%) cases. A relation between these factors and fetal demise was possible in nine (15%) and probable in seven (12%) of these cases. Inadequate management and recognition of suspected growth restriction (n=9) or hypertension (n=6) were the most common substandard care factors. Ten (16.7%) women felt none or decreased fetal movements for 24 hours or more before they consulted a doctor or midwife. CONCLUSION: Twenty-seven percent of all stillbirths were possibly or probably avoidable. Special attention to the recognition and adequate management of suspected growth restriction and hypertension as well as guidelines about patient information and management of decreased fetal movements might result in a reduction of stillbirths in the Netherlands.

Maternal characteristics of a cohort of preterm infants with a birth weight ≤750 g without major structural anomalies and chromosomal abnormalities.

Our objectives were to describe the obstetric complications of women who delivered an extremely low-birth-weight infant by comparing two consecutive 5-year periods and infants appropriate for gestational age (AGA) versus infants small for gestational age (SGA). This descriptive study included women ( N = 261) who delivered an infant ≤750 g (major structural and chromosomal anomalies excluded) between 1996 and 2000 (cohort I, N = 145) and 2001 to 2005 (cohort II, N = 116) in the University Hospital Utrecht, the Netherlands. Of these, 84.3% of the multigravidas ( N = 121) had a complicated obstetric history: 46.3% miscarriage(s), 22.3% preterm deliveries, and 16.5% hypertensive disorders. In the index pregnancies ( N = 261), the most prevalent complications were hypertensive disorders (52.1%, P = 0.002; more in cohort II) and SGA ( P = 0.007), fetal distress (39.5%), and intrauterine growth restriction (32.6%) resulting in a caesarean section in 47.9% and a spontaneous vaginal delivery in 19.2%. Intrauterine deaths occurred in 35.2%, merely due to placental insufficiency (59.8%) and termination of pregnancy because of deteriorating hypertensive disorders (23.9%). A high percentage of parous mothers had a seriously complicated obstetric history. The index pregnancy was largely complicated by hypertensive disorders. The majority of infants with a birth weight ≤750 g were growth-restricted due to placental insufficiency. Follow-up is extremely important to evaluate neonatal morbidity and neurodevelopmental outcome.

Outcome and complications of retropubic and transobturator midurethral slings translated into surgical therapeutic indices.

OBJECTIVE: We sought to determine and compare surgical therapeutic indices (STIs) of the retropubic tension-free vaginal tape (TVT) and 2 kinds of transobturator tape (TOT), Monarc (American Medical Systems, Minneapolis, MN), and tension-free vaginal tape obturator. STUDY DESIGN: This was a retrospective cohort study. Patients with predominant stress urinary incontinence who underwent retropubic (TVT, n = 257) or TOT (n = 180) procedures were included. STIs for both groups were calculated by dividing cure by complication rate at, respectively, 2 and 12 months. RESULTS: Two months after surgery the STI was significantly higher after TOT whereas 12 months after surgery results of STIs were equal. The explanation is more durable cure rates and declining long-term side effects after TVT procedures. CONCLUSION: Both surgical approaches seem to have their own benefits. Based on the STI, the balance between cure rate and complications is on the short term in favor of TOT but on the long term similar for TOT and retropubic TVT.

Perspectives by patients and physicians on outcomes of mid-urethral sling surgery.

INTRODUCTION AND HYPOTHESIS: The aim of this study is to determine patient expectations regarding wanted and unwanted sequels of mid-urethral sling (MUS) procedures and to identify mismatches during the physician-patient information exchange prior to MUS procedures. METHODS: A patient preference study (40 patients) and a questionnaire study with 20 experts as control group were conducted. Seventeen different sequels, defined by an expert team, were evaluated. RESULTS: Both patients and expert physicians ranked cure and improvement of stress urinary incontinence as the most important goals of treatment. De novo urge urinary incontinence, requiring post-operative intermittent self-catheterisation and dyspareunia were considered to be the most important complications by patients. Time to resume work after the operation and dyspareunia were among the highest rated sequels in the patient group compared to re-operation and intra-operative complications in the expert group. CONCLUSIONS: No differences were found in the five most important outcome parameters. In pre-operative counselling and future clinical trials, time to resume work and dyspareunia should be given more consideration by clinicians.

When to perform urodynamics before mid-urethral sling surgery for female stress urinary incontinence?

INTRODUCTION AND HYPOTHESIS: Development of a model that can predict in which group of women pre-operative urodynamics can be safely omitted. METHODS: Three hundred and eighty-one uncomplicated women who underwent pre-operative urodynamics were evaluated. A multivariate logistic regression model was developed based on medical history and physical examination predicting a high probability group of women with detrusor overactivity or a low (<20 cm H2O) mean urethral closure pressure and, therefore, are likely to benefit from urodynamics. RESULTS: Women are likely to benefit from pre-operative urodynamics if they (1) are 53 years of age or older or (2) have a history of prior incontinence surgery and are at least 29 years of age or (3) have nocturia complaints and are at least 36 years of age. CONCLUSION: If urogynaecologists omitted pre-operative urodynamics in women in the low probability group, in our population, pre-operative urodynamics would be reduced by 29%.

Cost-effectiveness of recurrence risk guided care versus care as usual in women who suffered from early-onset preeclampsia including HELLP syndrome in their previous pregnancy (the PreCare study).

BACKGROUND: Preeclampsia and HELLP syndrome may have serious consequences for both mother and fetus. Women who have suffered from preeclampsia or the HELLP syndrome, have an increased risk of developing preeclampsia in a subsequent pregnancy. However, most women will develop no or only minor complications. In this study, we intend to determine cost-effectiveness of recurrence risk guided care versus care as usual in pregnant women with a history of early-onset preeclampsia. METHODS/DESIGN: We developed a prediction model to estimate the individual risk of recurrence of early-onset preeclampsia and the HELLP syndrome. In a before-after study, pregnant women with preeclampsia or HELLP syndrome in their previous pregnancy receiving care as usual (before introduction of the prediction model) will be compared with women receiving recurrence risk guided care (after introduction of the prediction model). Eligible and pregnant women will be recruited at six university hospitals and seven large non-university tertiary referral hospitals in the Netherlands. The primary outcome measure is the recurrence of early-onset preeclampsia or HELLP syndrome in women allocated to the regular monitoring group. For the economic evaluation, a modelling approach will be used. Costs and effects of recurrence risk guided care with those of care as usual will be compared by means of a decision model. Two incremental cost-effectiveness ratios will be calculated: 1) cost per Quality Adjusted Life Year (mother unit of analysis) and 2) cost per live born child (child unit of analysis). DISCUSSION: This is, to our knowledge, the first study that evaluates prospectively the efficacy of a multivariable prediction rule for recurrent hypertensive disease in pregnancy. Results of this study could either be integrated into the current guideline on Hypertensive Disorders in Pregnancy, or be used to develop a new guideline.

Use of progesterone treatment for the prevention of recurrent preterm birth: identification of obstacles to change.

Progesterone treatment has proven to be effective in preventing recurrent preterm birth. The use of progesterone varies widely between different obstetric clinics in the Netherlands. The study aimed to identify factors that hamper or facilitate the use of progesterone to create an implementation strategy. A Web-based survey was developed containing questions on sociopolitical factors, organizational factors, knowledge, and attitude. This survey was spread among 212 gynecologists, 203 midwives, and 130 women with a recent preterm birth. Response rates were 46% for gynecologists, 57% for midwives, and 78% for patients. Twenty-five percent of gynecologists were prescribing progesterone, 21% of midwives would recommend progesterone, and 54% of patients were willing to undergo treatment in future pregnancies. Specific factors hampering implementation for gynecologists were working in nonteaching hospitals and absence of progesterone treatment in local protocols. For midwives and patients, unfamiliarity with progesterone was the most notable finding. The major reason for failure of implementation of progesterone treatment to prevent recurrent preterm birth is absence of this treatment in protocols and lack of familiarity with this treatment in midwives and patients. This may be overcome through adjustment of clinical protocols on regional and national levels.

Predictive value of urodynamics on outcome after midurethral sling surgery for female stress urinary incontinence.

OBJECTIVE: The aim of this study was to evaluate the value of urodynamic investigation in the preoperative workup of midurethral sling surgery and to identify risk factors for failure after 3 different midurethral sling procedures. STUDY DESIGN: Retrospective cohort study. 437 women who underwent a tension-free vaginal tape, Monarc, or tension-free vaginal tape-obturator procedure without other simultaneously performed urogynecological surgery were included. Preoperative data were collected from the medical files. Patients who reported any amount of leakage were considered failures. The mean follow-up of the study population was 14 months. RESULTS: After multivariate analysis, mixed urinary incontinence (P = .04), previous incontinence surgery (P = .022), and detrusor overactivity (P = .02) were significantly related to failure of midurethral sling procedures. There were no predictive urodynamic parameters for failure in patients with mixed urinary incontinence or previous incontinence surgery. CONCLUSION: The standard use of urodynamic investigation in the preoperative workup of midurethral sling surgery needs to be revisited.

Risk factors for failure of retropubic and transobturator midurethral slings.

OBJECTIVE: The aim of our study was to identify and compare risk factors for failure of retropubic and transobturator procedures. STUDY DESIGN: This was a retrospective cohort study. Women with predominant stress urinary incontinence who underwent a retropubic (n = 214) or transobturator tape procedure (n = 173) were included. Therapy was considered to have failed in women reporting any amount of urine leakage during stress after 2 and/or 12 months. RESULTS: Risk factors for failure were mixed urinary incontinence (MUI; odds ratio [OR], 3.7; 95% confidence interval [CI], 1.5-9.1) and the observation of detrusor overactivity (DO) at urodynamics (OR, 8.6; 95% CI, 1.9-39.4) in the retropubic group. Reporting a history of previous incontinence surgery (OR, 3.9; 95% CI, 1.3-11.7) and a low mean urethral closure pressure (MUCP) at urodynamics (OR, 14.5; 95% CI, 1.5-139.0) were risk factors for failure in the transobturator group. CONCLUSION: Women with previous incontinence surgery or a low MUCP might benefit more from a retropubic sling, whereas a transobturator procedure might be preferable in women with MUI or DO.

Pessaries in multiple pregnancy as a prevention of preterm birth: the ProTwin Trial.

BACKGROUND: Multiple pregnancies are at high risk for preterm birth, and therefore an important cause of infant mortality and morbidity. A pessary is a simple and potentially effective measure for the prevention of preterm birth. Small studies have indicated its effectiveness, but large studies with sufficient power on the subject are lacking. Despite this lack of evidence, the treatment is at present applied by some gynaecologists in The Netherlands. METHODS/DESIGN: We aim to investigate the hypothesis that prophylactic use of a cervical pessary will be effective in the prevention of preterm delivery and the neonatal mortality and morbidity resulting from preterm delivery in multiple pregnancy. We will evaluate the costs and effects of this intervention. At study entry, cervical length will be measured. Eligible women will be randomly allocated to receive either a cervical pessary or no intervention. The cervical pessary will be placed in situ at 16 to 20 weeks, and will stay in situ up to 36 weeks gestation or until delivery, whatever comes first.The primary outcome is composite bad neonatal condition (perinatal death or severe morbidity). Secondary outcome measures are time to delivery, preterm birth rate before 32 and 37 weeks, days of admission in neonatal intensive care unit, maternal morbidity, maternal admission days for preterm labour and costs. We need to include 660 women to indicate a reduction in bad neonatal outcome from 7.2% without to 3.9% with a cervical pessary, using a two-sided test with an alpha of 0.05 and a power of 0.80. DISCUSSION: This trial will provide evidence on whether a cervical pessary will decrease the incidence of early preterm birth and its concomitant bad neonatal outcome in multiple pregnancies. TRIAL REGISTRATION: Current Controlled Trials: NTR 1858.

Cardiovascular risk factor assessment after pre-eclampsia in primary care.

BACKGROUND: Pre-eclampsia is associated with an increased risk of development of cardiovascular disease later in life. It is not known how general practitioners in the Netherlands care for these women after delivery with respect to cardiovascular risk factor management. METHODS: Review of medical records of 1196 women in four primary health care centres, who were registered from January 2000 until July 2007 with an International Classification of Primary Care (ICPC) code indicating pregnancy. Records were searched for indicators of pre-eclampsia. Of those who experienced pre-eclampsia and of a random sample of 150 women who did not, the following information on cardiovascular risk factor management after pregnancy was extracted from the records: frequency and timing of blood pressure, cholesterol and glucose measurements--and vascular diagnoses. Additionally the sensitivity and specificity of ICPC coding for pre-eclampsia were determined. RESULTS: 35 women experienced pre-eclampsia. Blood pressure was more often checked after pregnancy in these women than in controls (57.1% vs. 12.0%, p<0.001). In 50% of the cases blood pressure was measured within 3 months after delivery with no further follow-up visit. A check for glucose and cholesterol levels was rare, and equally frequent in PE and control women. 20% of the previously normotensive women in the PE group had hypertension at one or more occasions after three months post partum versus none in the control group. The ICPC coding for pre-eclampsia showed a sensitivity of 51.4% and a specificity of 100.0%. CONCLUSION: Despite the evidence of increased risk of future cardiovascular disease in women with a history of pre-eclampsia, follow-up of these women is insufficient and undeveloped in primary care in the Netherlands.

Maternal and infant characteristics associated with perinatal arterial stroke in the preterm infant.

BACKGROUND AND PURPOSE: Most perinatal arterial stroke (PAS) studies that investigated infant characteristics have excluded preterm infants from the study population. We sought to analyze the imaging findings and antenatal and perinatal risk factors in preterm infants with PAS. METHODS: This was a hospital-based, case-control study of preterm infants. Case infants were confirmed by reviewing brain imaging scans and medical records (n=31). Three controls per case were individually matched with case infants from the study population. RESULTS: Gestational age ranged between 27 and 36 weeks, and birth weight ranged between 580 and 3180 g. PAS was more common on the left side (61%), and 7% had bilateral PAS. The majority of strokes involved the middle cerebral artery distribution. Involvement of 1 or more lenticulostriate branches was most common among infants with a gestational age of 28 to 32 weeks, but main branch involvement was seen only in those with a gestational age of >32 weeks. Twin-to-twin-transfusion syndrome, fetal heart rate abnormality, and hypoglycemia were identified as independent risk factors for PAS. CONCLUSIONS: Preterm PAS is associated with prenatal, perinatal, and postpartum risk factors. We were unable to identify any maternal risk factors. Involvement of the different branches of the middle cerebral artery changed with an increase in gestational age.

Pregnancy outcome after intra-abdominal bleeding due to placenta percreta at 14 weeks of gestation.

BACKGROUND: With the rising rate of cesarean deliveries, the rate of placenta previa and placenta percreta will rise concomitantly resulting in a greater incidence of severe complications. CASE: This case report describes a pregnancy with a massive intra-abdominal bleeding due to placenta percreta at 14 weeks of gestation. Several management options were discussed, and finally continuation of pregnancy was chosen. No further complications occurred, and in the 35th week, an elective cesarean delivery and hysterectomy were performed. A healthy male newborn of 2,400 g was born. CONCLUSION: While the outcome of pregnancy was favorable in this case, it does not rule out the possibility of severe complications with this management.
