[TERMINATION OF PREGNANCY DUE TO FETAL ABNORMALITIES PERFORMED AFTER 24 WEEKS OF GESTATION: THE EXPERIENCE OF THE DEPARTMENT OF OBSTETRICS AND GYNECOLOGY AT SHAMIR (ASSAF HAROFE) MEDICAL CENTER BETWEEN THE YEARS 1998-2021].

BACKGROUND: Termination of pregnancy is a difficult moral dilemma that provokes a discussion in the public, from an ethical, moral and religious point of view. This process is complex, especially when it comes to a fetus at a viability age (late abortion, after week 24), which requires the approval of a regional supreme committee. OBJECTIVES: To examine the various causes of abortion both before and after the fetal viability age (24 weeks of gestation and beyond) in a singleton pregnancy, as well as to examine the sequence of events that led to a late abortion. METHODS: In this cohort study, 4,057 patients who had abortions due to fetal abnormalities in the Shamir Medical Center during the years 1998-2021, were divided according to the abortion indications. Of these, 3539 (91.28%) had early abortion (24 weeks and below) and 338 (8.72%) had late abortions (24 week and later). RESULTS: In general, the leading reasons for abortions are chromosomal and genetic (1862 [46%]) as well as anatomical indication (1868 [46%]). It was found that the leading indication for early abortion is the chromosomal or genetic abnormalities (1702 [48.1%]), while the leading indication for late abortion is anatomical defects (204 [60.4%]) (p=0.000). In late abortion, the leading anatomical cause is heart defects (62 [30.54%]) followed by central nervous system defects (56 [26.6%]), and the leading chromosomal cause is trisomy 21 (Down syndrome) (23 [22.33%]). When examining the sequence of events that led to late abortion, the leading reason is abnormal findings that required further studies (125 [37%]). CONCLUSIONS: There is great importance in trying to reduce late pregnancy abortion by understanding the sequence of events and the reasons that led to it. Changing the processes that need to be performed can be implemented by combining pathways: improving the technological means, using more accurate instrumentation and advanced molecular genetics. Furthermore, it is essential to raise the awareness of the pregnant women on screening tests, and conducting this as early as possible. Additionally, it is important to raise the skill of the operators. We believe that incorporating all those actions will lead to earlier diagnosis and to a decrease in late abortions, a promising message both from the point of view of the women and the medical staff, due to the difficulty in carrying out late pregnancy terminations.

Outcomes of Cesarean Scar Pregnancies in Early Gestation According to the New Delphi Consensus Criteria.

OBJECTIVES: Clinical evaluation of the new Delphi consensus definition of cesarean scar pregnancy (CSP) in early gestation. METHODS: A retrospective cohort of 36 women diagnosed with CSP and treated with combined local and systemic methotrexate (MTX) between 2008 and 2021. The CSPs were classified according to the new Delphi consensus criteria into three subgroups based on the depth of the gestational sac herniation in the sagittal plane. Subgroup A included 8 (22.2%) cases in which the largest part of the gestational sac protruded toward the uterine cavity. Subgroup B included 22 (61.1%) cases in which the largest part of the gestational sac was embedded in the myometrium, and subgroup C included 6 (16.7%) cases in which the gestational was partially located outside the outer contour of the cervix or uterus. RESULTS: The ß-HCG level upon admission was significantly lower in subgroup A than in subgroups B or C (11,075 ± 7109, 18,787 ± 16,585, and 58,273 ± 55,267 mIU/mL, respectively, P = .01). All subgroup C patients had repeated courses of MTX and surgical interventions (laparotomy, uterine artery embolization, and operative hysteroscopy) at double the rate of subgroups A or B (100, 50, and 40.9%, respectively, P = .036). The duration of hospitalization was significantly shorter in subgroup A than in subgroups B or C (1.9 ± 1.5, 2.1 ± 1.1, and 5.4 ± 4.9 days, P = .01). CONCLUSIONS: The outcome according to Delphi consensus criteria for defining CSP in early gestation has implications for clinical decision-making, patient care, and the follow-up of CSP.

Caesarean scar pregnancy: is there a light in the end of the tunnel?

PURPOSE: To summarize and present a single tertiary center's 25 years of experience managing patients with caesarean scar pregnancies and their long-term reproductive and obstetric outcomes. METHODS: A 25-year retrospective study included women diagnosed with CSP from 1996 to 2020 in one tertiary center. Data were retrieved from the medical records and through a telephone interview. Diagnosis was made by sonography and color Doppler. Treatments included methotrexate, suction curettage, hysteroscopy, embolization and wedge resection by laparoscopy or laparotomy as a function of the clinical manifestations, the physicians' decisions, patient counseling, and parental requests. RESULTS: Analysis of the records recovered 60 cases of CSP (two of whom were recurrent). All patients had complete resolution with no indication for hysterectomy. Thirty-five patients had a long-term follow-up, of whom 24 (68.6%) attempted to conceive again and 22 (91.6%) succeeded. There were 17/22 (77.3%) patients with at least one live birth, 3/22 (13.6%) spontaneous miscarriages and 2/22 (9%) recurrent CSP. The obstetric complications included abnormal placentation 5/19 (26.3%), premature rupture of membranes 2/19 (10.5%), preterm delivery 4/19 (21%) and abnormality of the uterine scar 2/19 (10.5%). There was one case of neonatal death due to complications of prematurity 1/19 (5.2%). CONCLUSION: CSP treatment focusing on reducing morbidity and preserving fertility has encouraging long-term reproductive and obstetric outcomes. In subsequent pregnancies, we recommend performing an early first trimester vaginal scan to map the location of the new pregnancy, followed by close monitoring given the obstetric complications mentioned above.

Pregnancy with Facial Cleft: 20 Years of Experience at a Single Center.

BACKGROUND: Fetal facial clefts are among the most common congenital anomalies detected prenatally. This finding may lead to termination of pregnancy in some cases. OBJECTIVES: To compare a cohort of fetuses with facial clefts in which the pregnancy was terminated to the cohort of cases that were born with facial clefts. To investigate risk factors for facial clefts. METHODS: We conducted a retrospective chart review of all women with prenatal and postnatal diagnosis of facial cleft that were managed in our institute. A telephone questionnaire was conducted regarding a positive family history and/or genetic predisposition for facial clefts abnormalities. RESULTS: The final cohort consisted of two group. One group included 54 cases of termination of pregnancy (TOP) that were performed due to cleft lip (CL) or cleft palate (CLP); 27 women answered the telephone questionnaire. The second group comprised 99 women who delivered children with facial cleft during the same period; 60 answered the questionnaire. Only seven cases were diagnosed prenatal. Among the two groups, no correlation to family history was discovered. Of note, there was one case of three consecutive fetuses with CL in one woman, without any significant genetic findings. CONCLUSIONS: To the best of our knowledge, this is the first study to describe an anatomical malformation posing an ethical dilemma before TOP. Primary prevention with folic acid and early sonographic detection of CL/CLP with multidisciplinary consultation should be considered.

Tubal patency assessment using sequential transvaginal ultrasound and hysterosalpingo-foam sonography after methotrexate treatment for tubal pregnancy.

RESEARCH QUESTION: What is the efficacy of sequential two-dimensional transvaginal ultrasound (2D-US) and hysterosalpingo-foam sonography (HyFoSy) after methotrexate (MTX) treatment for tubal pregnancy among patients who desire a future pregnancy? DESIGN: A prospective trial conducted between May 2019 and November 2020. Patients who had a suspected tubal ectopic pregnancy diagnosed by ultrasound and treated by MTX were included. These patients underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. The primary outcome was tubal obstruction in the affected side. RESULTS: A total of 360 women underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. Of these, 40 (11.1%) women fulfilling the inclusion criteria were enrolled. In six out of 40 (15%), hydrosalpinx of the affected tube was found during the initial transvaginal ultrasound examination and were excluded from further investigation. In the remaining 34 (85%) patients, HyFoSy was carried out. Tubal block was found in 10 out of 34 (29.4%) patients. Of these, eight out of 34 (23.5%) and two out of 34 (5.9%) had a proximal block of the affected tube and bilateral proximal obstruction, respectively. Hysterosalpingography confirmed the tubal obstruction in all the affected cases. No procedure-related complications were documented. CONCLUSIONS: Forty per cent of women who were treated by MTX for tubal pregnancy were diagnosed with tubal obstruction. We recommend that sequential transvaginal ultrasound and HyFoSy become part of routine follow-up for these women, thus offering them timely referral to the appropriate specialist.

Similar but different: A comparison of rare site ectopic pregnancies.

OBJECTIVES: A comparative examination of the clinical, laboratory, ultrasound findings, and operative characteristics of rare site located ectopic pregnancies. METHODS: Retrospective analysis of all department cases of rare site located ectopic pregnancies diagnosed and treated from December 2006 to December 2019. RESULTS: Thirty rare ectopic pregnancies were identified. Of these, 11 were ovarian, 10 were interstitial and 9 were tubal stump. The patients treated for ovarian pregnancy had significantly lower human chorionic gonadotropin (hCG) levels than patients treated for interstitial or stump pregnancies (2025 ± 1105 mIU/ml, 18,424 ± 2579 mIU/ml and 11,204 ± 9221 mIU/ml, respectively, p = 0.003). The main presenting symptom in patients with an ovarian pregnancy was abdominal pain (90.9%, 60.0% and 44.4%, respectively, p = 0.031). Signs of abdominal peritoneal irritation (i.e., rebound tenderness and guarding) were more frequent upon physical examination in patients with an ovarian pregnancy (72.2%, 30.0% and 22.2%, respectively, p = 0.044) who also exhibited the highest rates of syncope and hypovolemic shock upon admission compared to patients with an interstitial or stump pregnancy (54.5%, 10.0% and 11.1%, respectively, p = 0.031). Ovarian pregnancies were associated with the lowest sonographic detection rates (9.1%, 80.0% and 100%, respectively, p = 0.0001) and with free fluid in the pouch of Douglas (72.7%, 20.0% and 22.2%, respectively, p = 0.02). Ovarian pregnancies experienced the highest rupture rate during surgery compared to interstitial or stump pregnancies (66.9%, 16.7% and 44.4%, respectively, p = 0.028), had a significantly higher estimated blood loss (1081 ± 647 ml, 760 ± 597 ml and 343 ± 318 ml, respectively, p = 0.003) and required blood transfusions in the perioperative period (63.6%, 20.0% and 11.1%, respectively, p = 0.025) significantly more often. CONCLUSIONS: Ovarian pregnancy remains the most challenging diagnosis compared to interstitial and tubal stump ectopic's. Health care providers should recognize these rare site ectopic pregnancies and to handle these gynecological emergencies promptly.

Recurrence of Ovarian Dermoid Cysts: A Single Center Experience.

BACKGROUND: Laparoscopic removal of ovarian dermoid cysts has been associated with increased risk for recurrence. OBJECTIVES: To investigate the risk factors associated with recurrence of dermoid cysts. METHODS: We conducted a retrospective review of all women who underwent cystectomy for ovarian dermoid cysts by laparoscopy or laparotomy. At discharge, patients were instructed to undergo a yearly ultrasound exam. A follow-up telephone call was conducted to assess whether an additional surgery for dermoid cysts was required and whether ultrasound recurrence of dermoid cysts was suspected. RESULTS: The study cohort included 102 participants (92 [90.2%] operated by laparoscopy and 10 [9.8%] by laparotomy). The mean follow-up from the index surgery to the interview was 72.1 ± 38.2 months. The rates of recurrent surgery were similar among women who underwent laparoscopic cystectomy compared with laparotomy (5/92 [5.4%] vs. 1/10 [10.0%], respectively; P = 0.5), while the rates of reported ultrasound recurrence were significantly lower in the laparoscopy group compared with the laparotomy group (10/102 [10.9%] vs. 4/10 [40.0%], respectively; P = 0.03). Additional factors including age, cyst diameter, diagnosis of torsion, intraoperative cyst spillage, estimated blood loss, intraperitoneal adhesions, and postoperative fever were not associated with recurrence. CONCLUSIONS: Ultrasound recurrence of dermoid cysts is not uncommon and could be associated with the surgical approach.

Second-trimester and early third-trimester spontaneous uterine rupture: A 32-year single-center survey.

BACKGROUND: Second-trimester and early third-trimester uterine rupture in a nonlaboring woman is a very rare and life-threatening condition for both mothers and newborns. We aimed to present clinical characteristics, prenatal findings, and maternal and neonatal outcomes following second-trimester and early third-trimester spontaneous antepartum uterine rupture in our institute. METHOD: The medical records of all women with full-thickness second-trimester and early third-trimester uterine rupture treated in our department from 1988 to 2019 were retrieved from the institutional database and reviewed. Small uterine defects, incomplete ruptures, and silent uterine incision dehiscence were excluded. RESULTS: From 1988 to 2019, 213 665 deliveries were recorded in our institute. Of these, 12 patients experienced second-trimester or early third-trimester spontaneous uterine rupture. Obstetric history revealed that 50% of the women in each period had undergone previous classical uterine incisions and 50% had a short interpregnancy (IP) interval. The mean age at diagnosis of uterine rupture was 26.3 ± 5.1 weeks. The ruptures were associated with abnormal placentation in 10 cases (83.3%): placenta previa (n = 7); and placenta previa and percreta (n = 3). No maternal mortality occurred. Seven of the 10 (70%) viable newborns survived. CONCLUSIONS: The increasing rates of cesarean births (CB) may lead to iatrogenic complications including midgestational prelabor spontaneous uterine rupture, an obstetric emergency, which is hard to diagnose. Maternal and neonatal outcomes can be optimized by a greater awareness of the risk factors, recognition of clinical signs and symptoms, and the availability of ultrasound to assist in establishing a diagnosis to enable prompt surgical intervention.

Analgesic Efficacy of Intrauterine Lidocaine Flushing in Hysterosalpingo-foam Sonography: A Double-blind Randomized Controlled Trial.

STUDY OBJECTIVE: To evaluate the efficacy of flushing the uterine cavity with lidocaine before hysterosalpingo-foam sonography (HyFoSy) to reduce procedure-related pain. DESIGN: A double-blind randomized controlled trial was conducted at the Department of Obstetrics and Gynecology, Shamir Medical Center, Israel between June 2020 and September 2020 involving 80 women undergoing a HyFoSy procedure. SETTING: University-affiliated medical center. PATIENTS: A total of 40 women were assigned randomly to the lidocaine group and 40 to the saline (placebo) group using a predetermined randomization code. Intrauterine instillation before the procedure consisting of either lidocaine 2% or normal saline alone was conducted, respectively. INTERVENTIONS: The primary outcome measure was the visual analog scale (VAS) pain score during the phase of intrauterine foam instillation reported by the women after the procedure. The VAS consisted of a 10-cm line ranging from 0 to 10 (anchored by 0 = no pain and 10 = very severe pain). On the basis of the VAS scores, the pain level ratings were classified as mild (rated 1-3), moderate (4-6), or severe (7-10). MEASUREMENTS AND MAIN RESULTS: The patient characteristics and obstetric data were found to be similar in both groups. Comparison of the VAS pain scores experienced during the procedure showed that women in the lidocaine flushing group rated the procedure less painful than the women in the saline group (3.0 ± 1.3 vs 6.3 ± 1.5, respectively; p = .001). The incidence of severe pain was significantly lower in the lidocaine group than the saline group (2.5% and 45.0%, respectively, p = .001). CONCLUSION: Lidocaine flushing of the uterine cavity before HyFoSy significantly decreased the pain known to be caused by this procedure and had the advantage of no side effects. It is easily applied, relatively inexpensive, and may affect compliance with this procedure.

Ovarian Dermoid Cysts Associated with Paraneoplastic Syndrome N-methyl-D-aspartic Acid Receptor Antibodies Encephalitis.

STUDY OBJECTIVE: To describe the incidence of ovarian dermoid cysts associated with paraneoplastic encephalitis syndrome due to N-methyl-D-aspartic acid (NMDA) receptor antibodies among women undergoing surgical resection of dermoid cysts. DESIGN: Retrospective cohort study. SETTING: University-affiliated department of obstetrics and gynecology. PATIENTS: All patients with pathology-proven ovarian dermoid cysts who underwent surgical resection in our department between January 2008 and December 2019. Their demographic, clinical, and surgical characteristics are described, with emphasis on cases diagnosed with anti-NMDA receptor encephalitis. INTERVENTIONS: Ovarian dermoid cyst resection by cystectomy or salpingo-oophorectomy. MEASUREMENTS AND MAIN RESULTS: A total of 233 patients were operated on for ovarian dermoid cysts, comprising 2 cases diagnosed with anti-NMDA receptor encephalitis (0.85%). Among the women without NMDA receptor encephalitis, the mean age was 33.3 ± 14.9 years, 84.0% were of reproductive age, 5.2% were premenarchal, and 10.8% were menopausal. The mean diameter of the dermoid cyst in this group was 77.3 ± 33.3-mm. The 2 patients diagnosed with anti-NMDA receptor encephalitis were 21 years old and 42 years old. The diameters of their dermoid cysts were 15-mm and 80-mm, respectively. The patients with anti-NMDA receptor encephalitis were managed with laparoscopic resection, plasmapheresis, intravenous immunoglobulins, and corticosteroids; 1 patient also received immunosuppressive treatment. Both recovered without significant neurologic sequela. CONCLUSION: Paraneoplastic syndrome due to NMDA receptor antibodies is a rare complication of dermoid cysts. This complication may occur in younger or older women, as well as in small- or large-diameter cysts. Thus, a high index of suspicion is required to correctly diagnose and treat women presenting with neurologic symptoms in the presence of dermoid cysts.

Hysterosalpingo-Foam Sonography for the Diagnosis of Tubal Occlusion: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis evaluated the diagnostic accuracy of hysterosalpingo-foam sonography in suspected cases of tubal occlusion. The combined sensitivity and specificity estimates were 0.99 (95% confidence interval [CI], 0.89-0.99) and 0.91 (95% CI, 0.53-0.98), respectively, with positive and negative likelihood ratios of 11.5 (95% CI, 1.5-87.5) and 0.006 (95% CI, 0.0003-0.12), respectively. The diagnostic odds ratio was 1931.008 (95% CI, 69.7-53,460.8). These findings confirm hysterosalpingo-foam sonography as a highly accurate test for the diagnosis of tubal occlusion and show that it is on a par with standard tests.

Impact of the Israeli Ministry of Health Cytomegalovirus Guidelines on the Local Pregnancy Outcome.

OBJECTIVE: In 2011, the Israeli Ministry of Health (MOH) published standard guidelines for the follow-up of pregnant women infected by CMV, recommending that amniocentesis be performed in cases of maternal serum viral seroconversion or abnormal sonographic findings suggestive of CMV, in order to prove fetal infection before electing for pregnancy termination. METHODS: A retrospective cohort study was performed, describing 448 pregnant women from 2006 to 2017. We collected data from all women that elected to continue their pregnancies after seroconversion and also of those who chose to undergo pregnancy termination. Subsequently, a telephone survey was then conducted to record outcomes of the newborns of women with CMV seroconversion during pregnancy. RESULTS: 325 (73%) women chose to continue their pregnancy, while 123 (27%) opted for termination of pregnancy. We found that pregnancy termination due to CMV infection was reduced by 7%, from 72 cases (32%) to 51 cases (25%) after the implementation of the MOH guidelines in 2011. In addition, 182/305 (60%) of women responded to our telephone questionnaire regarding newborn outcomes. Of these women, 45/305 (14%) reported complications, and no correlation was found between the prenatal findings and postnatal outcome among those who have responded to our survey. CONCLUSION: Implementation of the new MOH guidelines has reduced the rate of pregnancy termination, without increasing the rate of neonatal complications in Israel with a similar outcome of complication rate as reported in the literature.

Torsion of Functional Adnexal Cysts in Pregnancy: Aspiration and Drainage are Important in Preventing Recurrence.

BACKGROUND: Adnexal torsion in pregnancy is often associated with functional adnexal cysts, especially in pregnancies conceived by ovulation induction (OI) or in-vitro fertilization (IVF). During laparoscopy for adnexal de-torsion, drainage of the functional cysts can be attempted, although this procedure may cause bleeding. OBJECTIVES: To investigate the characteristics of ovarian torsion in pregnancy associated with functional cysts and to compare the rate of torsion recurrence following de-torsion alone versus cyst drainage. METHODS: All cases of surgically diagnosed adnexal torsion occurring during pregnancy between January 2007 and April 2019 in our department were retrospectively analyzed. The cases of torsion associated with presumed functional ovarian cysts were selected. The rate of recurrent torsion during the same pregnancy was compared for de-torsion alone versus de-torsion and cyst aspiration. RESULTS: Of the 113 women who experienced adnexal torsion during pregnancy, 71 (67.0%) of torsion cases were caused by presumed functional ovarian cysts. Among women with torsion of functional ovarian cysts, the rate of torsion recurrence was significantly higher in patients who underwent de-torsion alone (n=28) compared to women who underwent aspiration and drainage of the ovarian cysts (n=43) (14.3% vs. 0, P = 0.021). There were no cases of intra- or post-operative bleeding in the study cohort. CONCLUSIONS: Functional ovarian cysts are the most common adnexal pathology encountered in pregnant women with torsion. Intra-operative cyst aspiration and drainage may reduce the risk of recurrent torsion. Further multi-center studies are required to validate our data prospectively.

Long-Term Ultrasound Follow-Up After Pediatric Adnexal Torsion.

PURPOSE: Conservative surgical management of adnexal torsion in pre- and post-menarchal girls by de-torsion and adnexal conservation is the current standard of care. The aim of this study is to investigate the long-term outcome of adnexal torsion in this population in terms of ultrasound appearance and ovarian volume. METHODS: Patients who were surgically treated for adnexal torsion and were < 18 years old at time of surgery were prospectively invited for ultrasound follow-up. The ultrasound exam included measurements of ovarian volume and grayscale appearance including identification of ovarian follicular activity. RESULTS: 84 cases of torsion in this population were identified, and 37 of them were included in the study. Of those, the affected ovary could not be demonstrated on follow-up scan in six (16.2 %) cases. A difference of ≥ 2 cm3 in ovarian volume between the affected and non-affected ovaries was diagnosed in 12 (32.4 %) cases, but follicular activity was observed in 10 of those. Thus, possible ovarian injury (including cases of non-demonstrated ovary and volume difference of ≥ 2 cm3 between the affected and non-affected ovaries) was found in 18 (48.6 %) cases. Of the clinical and surgical parameters (including age at time of torsion, duration of pain prior to admission, cystectomy procedure and intraoperative "bluish" appearance of the ovary), only the presence of fever on admission was significantly associated with possible ovarian injury (p = 0.01). CONCLUSION: Long-term ultrasound follow-up of pre- and post-menarchal girls with a history of adnexal torsion may identify patients with adversely affected ovarian volume. The significance of this finding in terms of fertility is unknown.

Indications for genetic testing leading to termination of pregnancy.

PURPOSE: In this study, we aimed to assess the distribution of genetic abnormalities leading to termination of pregnancy and its fluctuation during the past 8 years in light of those technical advances. METHODS: Our cohort consisted of all pregnant women who underwent termination of pregnancy because of genetic aberrations in their fetuses from January 2010 through April 2018 in our medical center. The information that was gathered included: maternal age, results of the nuchal scan, results of the first- and second-trimester biochemical screening, ultrasonographic findings, reasons for conducting a genetic evaluation, gestational age at which termination of pregnancy was carried out, and the type of genetic aberration. RESULTS: 816 women underwent termination of pregnancy at our institution due to genetic aberrations, most of them because of positive biochemical screening (n = 297, 36%) or because of maternal anxiety (n = 283, 35%). Findings in chromosomal microarray led to termination of pregnancy in 100 women (100/816, 12%). Chromosomal microarray had been performed due to maternal choice and not because of accepted medical indications among most of the women who underwent termination of pregnancy due to findings on chromosomal microarray (69/100, 69%). CONCLUSION: Performing chromosomal microarray on a structurally normal fetus and identifying abnormal copy number variants may give the parents enough information for deciding on the further course of the pregnancy.

Impact of targeted scanning protocols on perinatal outcomes in pregnancies at risk of placenta accreta spectrum or vasa previa.

BACKGROUND: Placenta accreta spectrum and vasa previa (VP) are congenital disorders of placentation associated with high morbidity and mortality for both mothers and newborns when undiagnosed before delivery. Prenatal diagnosis of these conditions is essential to allow multidisciplinary management and thus improve perinatal outcomes. OBJECTIVE: The objective of the study was to compare perinatal outcome in women with placenta accreta spectrum or vasa previa before and after implementation of targeted scanning protocols. STUDY DESIGN: This retrospective study included 2 nonconcurrent cohorts for each condition before and after implementation of the corresponding protocols (2004-1012 vs 2013-2016 for placenta accreta spectrum and 1988-2007 vs 2008-2016 for vasa previa). Clinical reports of women diagnosed with placenta accreta spectrum and vasa previa during the study periods were reviewed and outcomes were compared. RESULTS: In total, there were 97 cases of placenta accreta spectrum and 51 cases with vasa previa, all confirmed at delivery. In both cohorts, the prenatal detection rate increased after implementation of the scanning protocols (28 of 65 cases [43.1%] vs 31 of 32 cases [96.9%], P < .001, for placenta accreta spectrum and 9 of 18 cases [50%] vs 29 of 33 cases [87.9%], 87.9%, P < .01 for vasa previa). The perinatal outcome improved also significantly in both cohorts after implementation of the protocols. In the placenta accreta spectrum cohort, the estimated blood loss and the postoperative hospitalization stay decreased between periods (1520 ± 845 vs 1168 ± 707 mL, P < .01, and 10.9 ± 14.1 vs 5.7 ± 2.2 days, P < .05, respectively). In the vasa previa cohort, the number of 5 minute Apgar score ≤5 and umbilical cord pH <7 decreased between periods (5 of 18 cases [27.8%] vs 1 of 33 cases [3%]; P < .05, and 4 of 18 cases [22.2%] vs 1 of 33 cases [3%], P < .05, respectively). CONCLUSION: The implementation of standardized prenatal targeted scanning protocols for pregnant women with risk factors for placenta accreta spectrum and vasa previa was associated with improved maternal and neonatal outcomes. The continuous increases in the rates of caesarean deliveries and use of assisted reproductive technology highlights the need to develop training programs and introduce targeted scanning protocols at the national and international levels.

The Rate of Cervical Length Shortening in the Management of Vasa Previa.

OBJECTIVES: There is no consensus about the optimal surveillance strategy in women with a diagnosis of vasa previa. The aim of this study was to evaluate the role of the rate of change in cervical length measurements in the management of singleton pregnancies with a diagnosis of vasa previa. METHODS: We performed a retrospective case-control study of our databases for pregnancies with a prenatal diagnosis of vasa previa that were followed with transvaginal sonography for cervical length and evaluated the impact of the changes in cervical length on the need for emergency cesarean delivery. RESULTS: The cohort included 29 singleton pregnancies with a prenatal diagnosis of vasa previa in the second trimester. There were 14 and 15 pregnancies that underwent elective and emergency cesarean delivery, respectively. The rate of cervical length shortening was significantly slower for women with elective compared to emergency cesarean delivery (median [range], 0.7 [0.1-2.0] versus 1.5 [0.25-3.0] mm/wk; P = .011). For each additional millimeter-per-week decrease in cervical length, the odds of emergency cesarean delivery increased by 6.50 (95% confidence interval, 1.02-41.20). The receiver operating characteristic curve for the rate of cervical length shortening in the prediction of emergency cesarean delivery yielded an area under the curve of 0.85 (95% confidence interval, 0.69-0.99). CONCLUSIONS: Our findings indicate an association between the rate of cervical length shortening and the risk of emergency cesarean delivery in pregnancies with a diagnosis of vasa previa in the second trimester. Further multicentric studies are required to validate our data prospectively and, in particular, the role of serial cervical length measurements in determining the optimal delivery time for individual cases.

Does she have adnexal torsion? Prediction of adnexal torsion in reproductive age women.

PURPOSE: The aim of this study was to investigate the association of clinical, laboratory and ultrasound findings with the surgical diagnosis of adnexal torsion in a retrospective cohort of women operated for suspected torsion. METHODS: The study included 199 reproductive age women > 16-year-old who underwent urgent laparoscopy for suspected adnexal torsion between January 2008 and December 2014. The association of various parameters with adnexal torsion was analyzed with a multivariate logistic regression analysis and described as odds ratios (OR) ± 95% confidence intervals (CI). RESULTS: Adnexal torsion was surgically diagnosed in 111/199 (55.8%) cases. On the multivariate logistic regression analysis, complaints of nausea/vomiting (OR 4.5, 95% CI 1.8-11.1), peritoneal irritation signs (OR 100.9, 95% CI 4.2-2421.9), elevated white blood cell count > 11,000 cells/mL (OR 3.7, 95% CI 1.3-10.8), presence of free pelvic fluid on ultrasound (OR 34.4, 95% CI 6.7-177.9), ultrasound findings suggestive of ovarian edema (OR 4.2, 95% CI 1.5-11.6), ultrasound findings suggestive of benign cystic teratoma (OR 7.8. 95% CI 1.2-49.4) and location of the ultrasound pathology on the right side (OR 4.7. 95% CI 1.9-11.9) were positively associated with adnexal torsion, while ultrasound findings suggestive of hemorrhagic corpus luteum cyst (OR 0.04, 95% CI 0.008-0.2) were negatively associated with adnexal torsion. By combining these eight parameters, the ROC curve was calculated, yielding an area under the curve of 0.93, 95% CI 0.90-0.97 (p < 0.0001). CONCLUSION: Routine clinical, laboratory and grayscale ultrasound findings may be incorporated into the emergency room workup of women with suspected adnexal torsion. Laparoscopy should be considered in all patients with suspected adnexal torsion.

Cesarean Scar Pregnancy and Morbidly Adherent Placenta: Different or Similar?

BACKGROUND: Growing evidence suggests that cesarean scar pregnancy (CSP) and morbidly adherent placenta (MAP) may represent a continuum of the same disease. OBJECTIVES: To investigate and compare the prior risk factors in women with either CSP or MAP. METHODS: The study included 33 women diagnosed with CSP in our department between 2006 and 2014. For each CSP case, two pregnant patients with MAP were matched for hospitalization date from delivery ward records, constituting the control group. RESULTS: In both groups, maternal age, parity, and previous early and late abortions were similar. The rate of conception by assisted reproductive technologies was 9% in both groups. Although the number of previous cesarean sections was statistically different between CSP versus MAP (2.0 ± 1.0 vs. 1.0 ± 1.0, respectively, P = 0.006), the leading indication of previous cesarean section was breech presentation in both groups (28.1% and 27.8%, respectively, P > 0.05). CONCLUSIONS: CSP and MAP share similar prior risk factors. Due to high morbidity in both diseases, further research is needed toward reducing the known etiological factors contributing to the growing number of both complications.
