First-trimester cesarean scar pregnancy: a comparative analysis of treatment options from the international registry.

BACKGROUND: A cesarean scar pregnancy is an iatrogenic consequence of a previous cesarean delivery. The gestational sac implants into a niche created by the incision of the previous cesarean delivery, and this carries a substantial risk for major maternal complications. The aim of this study was to report, analyze, and compare the effectiveness and safety of different treatments options for cesarean scar pregnancies managed in the first trimester through a registry. OBJECTIVE: This study aimed to evaluated the ultrasound findings, disease behavior, and management of first-trimester cesarean scar pregnancies. STUDY DESIGN: We created an international registry of cesarean scar pregnancy cases to study the ultrasound findings, disease behavior, and management of cesarean scar pregnancies. The Cesarean Scar Pregnancy Registry collects anonymized ultrasound and clinical data of individual patients with a cesarean scar pregnancy on a secure, digital information platform. Cases were uploaded by 31 participating centers across 19 countries. In this study, we only included live and failing cesarean scar pregnancies (with or without a positive fetal heart beat) that received active treatment (medical or surgical) before 12+6 weeks' gestation to evaluate the effectiveness and safety of the different management options. Patients managed expectantly were not included in this study and will be reported separately. Treatment was classified as successful if it led to a complete resolution of the pregnancy without the need for any additional medical interventions. RESULTS: Between August 29, 2018, and February 28, 2023, we recorded 460 patients with cesarean scar pregnancies (281 live, 179 failing cesarean scar pregnancy) who fulfilled the inclusion criteria and were registered. A total of 270 of 460 (58.7%) patients were managed surgically, 123 of 460 (26.7%) patients underwent medical management, 46 of 460 (10%) patients underwent balloon management, and 21 of 460 (4.6%) patients received other, less frequently used treatment options. Suction evacuation was very effective with a success rate of 202 of 221 (91.5%; 95% confidence interval, 87.8-95.2), whereas systemic methotrexate was least effective with only 38 of 64 (59.4%; 95% confidence interval, 48.4-70.4) patients not requiring additional treatment. Overall, surgical treatment of cesarean scar pregnancies was successful in 236 of 258 (91.5%, 95% confidence interval, 88.4-94.5) patients and complications were observed in 24 of 258 patients (9.3%; 95% confidence interval, 6.6-11.9). CONCLUSION: A cesarean scar pregnancy can be managed effectively in the first trimester of pregnancy in more than 90% of cases with either suction evacuation, balloon treatment, or surgical excision. The effectiveness of all treatment options decreases with advancing gestational age, and cesarean scar pregnancies should be treated as early as possible after confirmation of the diagnosis. Local medical treatment with potassium chloride or methotrexate is less efficient and has higher rates of complications than the other treatment options. Systemic methotrexate has a substantial risk of failing and a higher complication rate and should not be recommended as first-line treatment.

Minimally Invasive Treatment of Cesarean Scar and Cervical Pregnancies Using a Cervical Ripening Double Balloon Catheter: Expanding the Clinical Series.

The efficacy of treating cesarean scar pregnancies and cervical pregnancies with the Cook® cervical ripening balloon catheter, in a multicenter office-based setting is reported. Thirty-eight women were treated. Insertion of the catheter was performed under real-time ultrasound guidance. Patients received adjuvant systemic methotrexate, prophylactic oral antibiotics, and oral pain medication. Serum human chorionic gonadotropin and ultrasound scans were followed serially until resolution. Thirty-seven patients were successfully treated, requiring no further procedures. We found that the Cook cervical ripening balloon technique is a simple, effective, outpatient, minimally invasive treatment with few complications noted in this expanded series.

Integrating Microarrays into Routine Prenatal Diagnosis: Determinants of Decision Making.

OBJECTIVES: The explosion in genetic technologies, including array comparative genomic hybridization (aCGH), has increased the complexity of genetic counseling. We now offer chorionic villus sampling (CVS) and aCGH to all first-trimester patients, as this allows the prenatal diagnosis of an additional 1% of anomalies not otherwise detectable and can detect genetic copy number variants at a much higher resolution than conventional cytogenetics. Here, we explored some of the determinants of how patients are deciding to use or not use this new technology and evaluate risk-benefit analyses for that decision. METHODS: This is a retrospective case-control study of singleton and multiples pregnancies at our center. Those having aCGH testing along with CVS were defined as 'testers' and those who declined aCGH but had the CVS were 'nontesters'. RESULTS: Demographic data of 181 educated women who chose CVS were compared. Among those carrying singletons (n = 144), older women, defined as over 35 years of age (or 'advanced maternal age'; AMA), were more likely to choose the aCGH than younger women. Further, women who had a prior history of genetic testing and who wanted to know the gender of the fetus were more likely to choose the aCGH test. In women carrying multiples (n = 37), AMA ceases to be a predictor of choice. Having had prior genetic counseling remains a strong predictor for choosing aCGH, as does wanting to know the gender of the fetus. Neither prior abortions nor having prior children were significant for women carrying singletons or multiples. CONCLUSION: Offering pregnant couples an individualized choice regarding aCGH seems an appropriate approach. There are discrete patterns associated with the choice of taking the aCGH that varied depending on whether the patient was carrying a singleton or multiples.

Intrauterine Adenosine Administration for the Treatment of Fetal Supraventricular Tachycardia in a Fetus With Aortic Stenosis.

Fetal tachyarrhythmia and aortic stenosis (AS) both disrupt fetal hemodynamics, leading to congestive heart failure, hydrops, and intrauterine demise. Traditional transplacental treatments for fetal supraventricular tachycardia (SVT) include digoxin, flecainide, and sotalol. However, the treatment of fetal SVT in the setting of AS has not been described, particularly in cases of refractory SVT. We present a case of a 27-year-old nulliparous female carrying a fetus with fetal AS diagnosed at 25 weeks of gestational age (GA). The patient was not a candidate for in utero valvuloplasty. During ultrasound monitoring at 32 and 6/7 weeks of gestation, fetal SVT with a heart rate of 230-260 beats per minute (bpm) was diagnosed. Maternal digoxin was initiated, and sotalol was subsequently added. Due to persistent fetal SVT and a worsening cardiac function, the patient was treated with direct adenosine administration via cordocentesis successfully terminating the fetal arrhythmia. Despite continued transplacental treatment with digoxin and sotalol throughout the course of pregnancy, the fetal SVT recurred at 35 and 5/7 weeks of gestation prompting delivery. Our case illustrates the use of direct intrauterine adenosine as a novel treatment for refractory fetal SVT in the setting of congenital aortic stenosis and concern about progression to fetal hydrops and fetal demise.

Impact of an accessory cavitated uterine mass on fertility: case presentation and review of the literature.

Objective: We report a case of an accessory cavitated uterine mass (ACUM) in a patient with infertility and chronic pelvic pain. In addition, we summarize the literature to better characterize ACUM diagnosis and management. Design: A comprehensive literature search using the PubMed database was performed through April 2023. Historical ACUM diagnostic criteria were applied as inclusion criteria. Descriptive statistics and statistical evaluation were reported. Results: A 31-year-old nulligravid woman presented with chronic pelvic pain, dysmenorrhea, primary infertility, and history of endometriosis. Three-dimensional ultrasonography identified an ACUM and laparoscopic excision provided complete resolution of symptoms. Subsequently, she conceived without assistance twice with uncomplicated vaginal deliveries. A total of 154 articles were identified, 34 papers met inclusion criteria and were individually reviewed, consisting of 70 reported cases. The most common presenting complaints were dysmenorrhea (81.4%), chronic pelvic/abdominal pain (54.1%), and refractory pain (34.3%). Diagnostic imaging included magnetic resonance imaging (62.9%) and transvaginal ultrasound (55.7%). Management included resection via laparoscopy (75.7%) or laparotomy (18.6%), or hysterectomy (5.7%). Of cases with reported outcomes, 90.7% had complete relief of symptoms after surgery. Conclusion: ACUM often presents with dysmenorrhea, chronic pelvic pain, or abdominal pain and is identifiable on magnetic resonance imaging as a hyperenhancing mass. Three-dimensional transvaginal ultrasound can also accurately identify ACUM. A total of 90.7% of patients had complete relief of symptoms after intervention. It is important to identify ACUM early to relieve pain and reduce unnecessary interventions. Like our patient, other reports have demonstrated concomitant infertility and endometriosis. However, further investigation is needed to explore the association between infertility and ACUM.

Sonographic Diagnosis and Management With Delayed Hysterectomy of Two Cesarean Scar Pregnancies That Developed Into Placenta Percreta: Two Case Reports.

Approximately two-thirds of the patients with a cesarean scar pregnancy (CSP) will develop placenta accreta spectrum (PAS). PAS occurs when the placenta attaches too deeply to the uterine wall, and sometimes, the placenta can extend beyond the uterus, invading surrounding organs. PAS is commonly managed with a cesarean hysterectomy, and these deliveries are often complicated by maternal and fetal morbidity and mortality. However, delaying hysterectomy and using chemotherapeutic agents may be a safe and beneficial alternative. We describe the case of a 32 -year-old G3P2002 with a history of two prior cesarean sections (CS) who was referred to our Maternal Fetal Medicine department due to the concern of a gestational sac embedded in the anterior uterine wall in the cesarean scar. Magnetic resonance imaging (MRI) findings at 33 weeks confirmed that the patient had developed placenta percreta extending into the sigmoid colon. We also describe the case of a 30-year-old G6P4104 with a history of four prior CS who was referred to our department for concern of a pregnancy complicated by CSP. This patient had an MRI performed at 23 weeks that showed placenta percreta invading the bladder. Patients one and two were managed with a staged procedure, with CS followed by a delayed laparoscopic and abdominal hysterectomy, respectively, to minimize bowel and bladder injury. After the CS, the patients subsequently received a five-day course of intravenous (IV) etoposide 100mg/m2, and at six weeks postpartum, the patients had a hysterectomy, both showing resolution of the placenta invasion into the surrounding organs on postpartum MRI and confirmed by tissue pathology reports. Our cases present the challenge in diagnosis and management of the most severe presentation of PAS that varies from the generally accepted management recommendations. Delayed hysterectomy with chemotherapy can be a reasonable, conservative surgical approach in the most severe types of PAS. As in our cases, this management could improve maternal and fetal morbidity and mortality.

Critical Care Management of a Severe Acute Respiratory Distress Syndrome COVID-19 Patient With Control Cesarean Section.

We share our experience of one 29-year-old female, G2 P1, with acute respiratory distress syndrome (ARDS) and at 30 weeks of pregnancy. The 30-week gravid uterus in combination with a poor ventilation-perfusion ratio creates a restrictive lung pattern that may prove to be lethal for both the mother and baby. Due to her rapid deterioration and increased hemodynamic instability we opted for controlled delivery in the operating room with an ICU physician, a Neonatologist, and an Obstetric team. At 3.27 minutes from induction, the baby was born with Apgar scores of 7 and 8. The mother was placed on a RotoProne® bed, treated with remdesivir, steroids, and was subsequently extubated seven days later. The newborn was admitted to the Neonatal Intensive Care Unit (NICU) after delivery. We have reviewed the literature and provided a concise set of recommendations based on our field experience and current world literature review. Prompt delivery in a controlled environment with multiple resuscitating teams provided expeditious treatment of both patients, maintaining oxygenation and perfusion while keeping hemodynamic stability. The controlled environment and the proximity of all teams avoided deleterious consequences to the unborn baby. This is an example where the risk of keeping the baby in the womb outweighs the premature delivery into a NICU. Both mother and baby were downgraded from their respective Intensive Care Units (ICUs) and discharged home in one month.

Antenatal Three-Dimensional Printing for Ex Utero Intrapartum Treatment Procedures.

BACKGROUND: Prenatal ultrasonography allows for timely identification of fetal abnormalities that can have an effect on securing the neonatal airway at delivery. We illustrate the role of antenatal three-dimensional printing in cases with fetal airway obstruction. CASE: We present two cases that highlight the utility of a three-dimensional printing technique to aid in ex utero intrapartum treatment procedures during cesarean delivery. CONCLUSION: Three-dimensional printing plays a complementary role to standard imaging options in optimizing presurgical planning, prenatal parental counseling, personalized patient care, and education of the multidisciplinary team in cases of fetal congenital airway obstruction.

Racial disparity in the clinical determinants and outcomes of cesarean hysterectomy.

This study was undertaken to compare the risk factors, indications for and complications rates of cesarean hysterectomy in patient from two different ethnic backgrounds-whites and nonwhites-using patients who had cesarean hysterectomy in the Detroit Medical Center from 1991-2007. During the study period, there were 42599 cesarean deliveries, making the incidence of cesarean hysterectomy to be 3.7 per 1000 cesarean deliveries. Of the 158 cases, 8.9% were planned, while 91.1% were emergent. Among the emergent cases, nonwhites were more likely to have a higher parity (median [range], 3 [0-13] vs. 2 [0-9]; p = .025), while whites were more likely to have a private insurance (64.7% vs. 29.1%; p = .001; OR, 4.47; 95% CI, 1.98-10.09]. There were no significant differences in the indications for cesarean hysterectomy among the racial groups. Whites were more likely to have composite cardiopulmonary complications and urological injury compared to nonwhites, (17.6% vs. 3.6%; P = .012; OR, 5.68; 95% CI, 1.50-21.51) and (26.5% vs. 10.9%; P = .05; OR 2.94; CI, 1.12-7.75), respectively. In conclusion, beyond higher rates of cardiopulmonary complications and urological injury among whites, no significant racial differences exist in the risk factors, indications for, and complications from cesarean hysterectomy.

Incidence, trends, risk factors, indications for, and complications associated with cesarean hysterectomy: a 17-year experience from a single institution.

PURPOSE: To review the incidence, trends, risk factors, indications for, and complications associated with cesarean hysterectomy (CH) in our institution. MATERIALS AND METHODS: Retrospective study of 158 women who had CH at the Detroit Medical Center during a 17 period. RESULTS: During the study period, 158 of 202,356 deliveries were CH, giving an overall incidence of 0.78 per 1,000 deliveries. Of the 158 cases, 14 were elective while 144 were emergently performed due to complications encountered at cesarean section. Analysis of the eligible 144 cases showed that the commonest risk factors were previous cesarean delivery (76%) and placenta previa (35%). Abnormal placenta adherence was the indication for CH in 50.7%, followed by uterine atony in 34.7% and uterine rupture in 16.7% of the cases. Febrile morbidity (44.4%) and disseminated intravascular coagulopathy (22.9%) were the most common postoperative complications. Most complications occurred in patients with parity greater than two. Compared to the last decade, CH performed more recently were less likely to be complicated by bowel injury or disseminated intravascular coagulopathy. CONCLUSION: Morbidly adherent placenta has replaced uterine atony as the leading indication for emergent CH in our institution. High parity remains a risk factor for complications; however, we recorded a reduction in bowel injury and disseminated intravascular coagulopathy in recent years.

Cerclage retention versus removal following preterm premature rupture of membranes and association with amniotic fluid markers.

OBJECTIVE: To evaluate whether amniotic fluid markers can aid the decision of whether to retain or remove a cervical cerclage after preterm premature rupture of membranes (PPROM). METHODS: A retrospective cohort study included pregnancies involving PPROM after diagnostic amniocentesis and cerclage placement. Cerclage was retained for more than 12 hours after PPROM in the study group (n=18); the comparison group comprised women who underwent immediate cerclage removal after PPROM (n=22). Analyses were performed using concentrations of interleukin (IL)-6, glucose, and white blood cells (WBCs) in the amniotic fluid to measure relationships with adverse outcomes. RESULTS: The latency period from PPROM to delivery was significantly shorter in the group that underwent immediate cerclage removal (P<0.005). Latency periods of more than 48 hours (P<0.001) and more than 7 days (P<0.01), and chorioamnionitis (P<0.05) were associated with cerclage retention. Neonatal outcomes were not significantly different between the study group and the comparison group. However, elevated IL-6 levels were associated with cumulative neonatal morbidity (P<0.05). Low IL-6 (P<0.001) and WBC (P<0.05) levels were significantly associated with a latency period of more than 7 days. CONCLUSION: Amniotic fluid levels of IL-6 and WBCs may be of clinical value for individualizing the management of patients with PPROM after cerclage.

Amniotic fluid inflammation with negative culture and outcome after cervical cerclage.

OBJECTIVE: To determine whether amniotic fluid (AF) inflammation, in the absence of infection, is associated with adverse pregnancy outcomes in nonelective cervical cerclage patients. METHODS: A retrospective case-control study was carried out. The patient population included 82 singleton pregnancies with negative AF cultures. The variables used to define AF inflammation were white blood cell count (WBC) >50 cell/mm(3), glucose <14 mg/dl or interleukin-6 (IL-6) >11.3 ng/ml. The study group consisted of cases with intra-amniotic inflammation. Sub-analysis was performed for the groups in which IL-6 concentrations were measured. Adverse outcomes were evaluated with variables such as gestational age at delivery, interval from cerclage to delivery, chorioamnionitis and cumulative neonatal morbidity. RESULTS: Elevated AF WBC was correlated with severe and extreme preterm delivery (p < 0.05). Decreased AF glucose was associated with histological chorioamnionitis and a decreased cerclage to delivery interval (p < 0.05). Elevated AF IL-6 correlated significantly with decreased gestational age at delivery (p < 0.012) and decreased cerclage to delivery interval (p < 0.001). Elevated IL-6 concentrations were associated with severe, extreme preterm delivery (p < 0.001) and neonatal death (p < 0.001). CONCLUSION: Elevated AF IL-6, elevated WBC and low AF glucose, in the absence of a positive AF culture, are significantly associated with adverse pregnancy outcomes in patients undergoing nonelective cerclage.

Male gender significantly increases risk of oxidative stress related congenital anomalies in the non-diabetic population.

OBJECTIVE: Oxidative stress (OS) is an important mechanism of teratogenesis. Recent work suggests increased OS in males. We evaluated whether male gender increased the risk of cyanotic congenital heart defects (CCHD) whose development is linked to OS and other common congenital anomalies (CA) in non-diabetic pregnancies. METHODS: CDC-National Center for Health Statistics data for 19 states in 2006 were reviewed. CCHD, anencephaly, spina bifida, congenial diaphragmatic hernia (CDH), omphalocele, gastroschisis, limb defects, cleft lip with or without cleft palate (CL/P) and isolated cleft palate were evaluated. Adjusted odds ratio (OR) (95% CI) were calculated for CA in males with females as the reference group. RESULTS: Of 1,194, 581, cases analyzed after exclusions, 3037 (0.25%) had major CA. Males had elevated adjusted OR (95% CI) for CCHD: 1.198 (1.027, 1.397), CDH: 1.487 (1.078, 2.051), and CL/P: 1.431 (1.24, 1.651). There was a significant interaction between cigarette use and (male) fetal gender and also with maternal age in the CL/P group. CONCLUSIONS: In non-diabetic pregnancies, male gender appears to be an independent risk factor for some types of CA believed to be associated with OS. Cigarette smoking, a well recognized source of OS only increased the risk of CL/P in males.

Evolución a largo plazo del infarto de ventrículo derecho / Long term follow-up of right ventricular infarction

Se estudia la evolución a largo plazo de 36 supervivientes a la fase hospitalaria de un infarto posteroinferior extendido al ventrículo derecho. El grupo lo constituyeron 7 mujeres y 29 varones con una edad media de 55 años. El tiempo de seguimiento fué de 39 meses como promedio. Se analizó la evolución en la fase aguda y se correlacionó con la mortalidad, complicaciones y capacidad funcional en la evolución a largo plazo. La mortalidad fué del 5.5%. Cinco pacientes desarrollarón un nuevo infarto de miocardio (16%). Ningún enfermo tuvo manifestación de insuficiencia cardíaca derecha durante su evolución tardía y en un solo caso se detectó insuficiencia tricuspídea. La mayor parte de los pacientes estaban en clase funcional I (55.5%) el 36.6% en clase II y el 8.3% en clase III. Ser concluye que la mortalidad a largo plazo de los pacientes con infarto del ventrículo derecho no es mayor que la de otros enfermos con infarto de miocardio; que la gran mayoría evolucionan favorablemente en cuanto a capacidad funcional y cuando no es así habitualmente es debido a una mala función ventricular izquierda secundaria a la gravedad y extensión de las lesiones coronarias; el subgrupo de pacientes con grave disfunción ventricular derecha durante la fase aguda del infarto no tuvo pronóstico peor a largo plazo
