Borderline Ovarian Tumours (BOTs) comprise 15–20 % of all epithelial ovarian tumours. BOTs are characterised by increased mitotic activity but lack infiltrative destructive growth and stromal invasion. Several dilemmas and controversies have been discussed in the literature regarding BOT management including surgical approach (radical versus fertility-sparing surgery), surgical route (open versus laparoscopic surgery) and impact on disease recurrence, follow-up protocols/modalities (imaging, serum biomarkers), role of completion surgery, lymph node dissection during staging, adjuvant chemotherapy, as well as use of Hormone-Replacement Therapy (HRT) post-surgery. We performed a structured narrative review on Medline and Cochrane Library Databases to identify studies pertaining to the management of BOTs. Identifying areas of agreement and outstanding uncertainty are integral to optimise robust treatment regimens for BOT management and improve the Quality of Life (QoL) and clinical outcomes for patients. We discuss a framework of recommendations to counsel, manage and follow-up women diagnosed with BOT.
交界性卵巢肿瘤(BOTs)占所有卵巢上皮肿瘤的15 - 20%。BOTs的特征是有丝分裂活性增加,但缺乏浸润性破坏性生长和基质侵袭。文献中已经讨论了关于BOT管理的几个困境和争议,包括手术方式(根治性手术还是保留生育能力的手术)、手术路线(开放手术还是腹腔镜手术)和对疾病复发的影响、随访方案/方式(影像学、血清生物标志物)、完成手术的作用、分期期间的淋巴结清扫、辅助化疗以及术后激素替代疗法(HRT)的使用。我们对Medline和Cochrane图书馆数据库进行了结构化的叙述性回顾,以确定与bot管理有关的研究。确定共识领域和突出的不确定性对于优化BOT管理的有力治疗方案和改善患者的生活质量(QoL)和临床结果是不可或缺的。我们讨论了一个建议框架,以咨询、管理和随访被诊断患有BOT的妇女。

<div><h3>Objective</h3><div>To investigate the predictive accuracy of the ultrasound-measured observed/expected (O/E) lung-to-head ratio (LHR) versus MRI-measured O/E total fetal lung volume (TFLV) in predicting postnatal survival in fetuses with an isolated congenital diaphragmatic hernia (CDH) undergoing expectant management.</div></div><div><h3>Methods</h3><div>A systematic review was conducted including studies reporting on the prognostic value of ultrasound-measured O/E LHR and MRI-measured O/E TFLV in predicting survival to hospital discharge in fetuses diagnosed with isolated CDH. Pregnancies undergoing fetal therapy were excluded. The overall accuracy was assessed by computing summary estimates of sensitivity, specificity, positive and negative likelihood ratios (LR+ and LR–), and diagnostic odds ratio (DOR), using the hierarchical summary receiver operating characteristics (HSROC) model. Synthetic analysis included studies in which the number of true-positive, false-positive, false-negative, and true-negative cases was available or deducible. We planned a subgroup analysis based on index test cut-offs and the side of CDH (left or right). Heterogeneity was assessed using Cochran's Q statistic.</div></div><div><h3>Results</h3><div>This systematic review included 33 studies comprising 1702 fetuses with isolated CDH published between 2000 and 2024. The meta-analysis included 18 studies encompassing 960 fetuses with ultrasound-measured O/E LHR and 742 fetuses with MRI-measured O/E TFLV. In the ultrasound studies, the pooled survival was 62 % compared to 68 % in the MRI studies. Both O/E LHR and O/E TFLV were significantly associated with survival (pooled O/E LHR 0.07, 95 % CI 0.04, 0.13; pooled O/E TFLV 0.09, 95 % CI 0.05, 0.17). In all severe CDH cases, both US and MRI appeared comparable. The O/E LHR had a pooled sensitivity of 72.2 % (95 % CI 64.9–78.4), specificity of 83.9 % (95 % CI 71.2–91.6), DOR of 13.5 (95 % CI 7.2–25.3), LR+ of 4.48 (95 % CI 2.5–8.0), and LR-of 0.33 (95 % CI 0.3–0.4). The O/E TFLV had a pooled sensitivity of 84 % (95 % CI 74.7 90.3), specificity of 62.5 % (95 % CI 45.5–76.8), DOR of 8.72 (95 % CI 3.4–22.4), +LR of 2.24 (95 % CI 1.4–3.5), and -LR of 0.26 (95 % CI 0.1–0.5). In the subgroup analysis of left-sided CDH, although the pooled sensitivity and DOR appeared higher using MRI, the 95 % CI overlapped: O/E LHR had a sensitivity of 73.6 (95 % CI 61.5–82.9), specificity 82.0 (95 % CI 63.8–92.2), DOR 12.7 (95 % CI 5.9–27.1), + LR 4.09 (95 % CI 2.0–8.2), and -LR 0.32 (95 % CI 0.2–0.5), while the O/E TFLV had sensitivity of 91.2 (95 % CI 79.7–96.5), specificity of 78.1 (95 % CI 65.3–87.1), DOR 37.1 (95 % CI 12.3–111.6), +LR 4.17 (95 % CI 2.5–6.9), and -LR 0.11 (95 % CI 0.04–0.3). While five studies investigated right-sided CDH in the ultrasound group, there was only one study in the MRI group. Seven studies included head-to-head comparison between prenatal ultrasound and MRI, of which the diagnostic accuracy appeared c
目的探讨超声测量的观察/预期(O/E)肺头比(LHR)与mri测量的O/E胎儿总肺容量(TFLV)对预期治疗的孤立性先天性膈疝(CDH)胎儿出生后生存的预测准确性。方法系统回顾了超声测量的O/E LHR和mri测量的O/E TFLV对诊断为孤立性CDH的胎儿存活至出院的预测价值。排除接受胎儿治疗的孕妇。总体准确性通过计算敏感性、特异性、阳性和阴性似然比(LR+和LR -)和诊断优势比(DOR)的汇总估计值来评估,采用分层汇总受试者操作特征(HSROC)模型。综合分析包括可获得或可推断的真阳性、假阳性、假阴性和真阴性病例数量的研究。我们计划基于指标检验截止点和CDH侧(左或右)进行亚组分析。异质性采用Cochran’s Q统计量进行评估。本系统综述纳入了33项研究,包括2000年至2024年间发表的1702例孤立性CDH胎儿。荟萃分析包括18项研究,包括960名超声测量的O/E LHR胎儿和742名mri测量的O/E TFLV胎儿。超声研究的总生存率为62%,而MRI研究的总生存率为68%。O/E LHR和O/E TFLV均与生存率显著相关(O/E LHR合计为0.07,95% CI 0.04, 0.13; O/E TFLV合计为0.09,95% CI 0.05, 0.17)。在所有严重CDH病例中,US和MRI结果均具有可比性。O/E LHR的总敏感性为72.2% (95% CI 64.9-78.4),特异性为83.9% (95% CI 71.2-91.6), DOR为13.5 (95% CI 7.2-25.3), LR+为4.48 (95% CI 2.5-8.0), LR为0.33 (95% CI 0.3-0.4)。O/E TFLV的总敏感性为84% (95% CI 74.7 - 90.3),特异性为62.5% (95% CI 45.5-76.8), DOR为8.72 (95% CI 3.4-22.4), +LR为2.24 (95% CI 1.4-3.5), -LR为0.26 (95% CI 0.1-0.5)。在左侧CDH的亚组分析中,尽管MRI显示合并敏感性和DOR更高,但95% CI重叠:O/E LHR的敏感性为73.6 (95% CI 61.5-82.9),特异性为82.0 (95% CI 63.8-92.2), DOR 12.7 (95% CI 5.9-27.1), +LR 4.09 (95% CI 2.0-8.2)和-LR 0.32 (95% CI 0.2-0.5),而O/E TFLV的敏感性为91.2 (95% CI 79.7-96.5),特异性为78.1 (95% CI 65.3-87.1), DOR 37.1 (95% CI 12.3-111.6), +LR 4.17 (95% CI 2.5-6.9)和-LR 0.11 (95% CI 0.04-0.3)。超声组有5项研究调查右侧CDH,而MRI组只有1项研究。7项研究包括产前超声与MRI的直接比较,所有CDH病例的诊断准确性均具有可比性(P = 0.14)。局限性包括测量方法的差异、可重复性、异质性和方法学问题。结论使用产前超声评估肺大小似乎与使用MRI评估产前诊断的孤立性严重CDH进行预期治疗(即未进行胎儿手术)的生存机会具有相当的准确性。这一发现在所有CDH病例和左侧CDH患者中都得到了证实。未来的研究应着眼于研究新的成像预后标志物,用于美国和MRI预测发病率和死亡率。

Intrauterine transfusion (IUT) remains the cornerstone of treatment for severe fetal anemia, particularly due to red blood cell alloimmunization, and is increasingly utilized in select non-immune conditions such as complicated monochorionic twins and parvovirus B19 infection. This narrative review provides a comprehensive overview of current best practices and recent developments in IUT therapy, including indications, diagnostic strategies, procedural techniques, outcomes, and emerging trends. Evidence-based guidelines, multicenter cohort studies, and expert consensus statements were reviewed, with particular attention to diagnosis and management of fetal anemia, procedural safety, timing, transfusion strategy, and center-level practices. The introduction of ultrasound-guided intravascular transfusion via the intrahepatic vein or placental cord insertion has markedly reduced procedure-related risks, resulting in survival rates exceeding 85 % in most settings and favorable long-term outcomes. Despite these advances, challenges persist for early gestational interventions and recurrent transfusions. Overall, IUT is a highly effective intervention for fetal anemia when performed in specialized centers with multidisciplinary expertise.
宫内输血(IUT)仍然是治疗严重胎儿贫血的基石,特别是由于红细胞异体免疫,并且越来越多地用于选择非免疫条件,如复杂的单绒毛膜双胞胎和细小病毒B19感染。这篇叙述性综述全面概述了目前IUT治疗的最佳实践和最新发展,包括适应症、诊断策略、程序技术、结果和新趋势。我们回顾了循证指南、多中心队列研究和专家共识声明,特别关注胎儿贫血的诊断和管理、程序安全性、时机、输血策略和中心层面的实践。超声引导下经肝内静脉或胎盘脐带插入血管内输血的引入显著降低了手术相关风险,在大多数情况下生存率超过85%,长期预后良好。尽管取得了这些进展,但在妊娠早期干预和反复输血方面仍然存在挑战。总的来说,IUT是一个非常有效的干预胎儿贫血时,在专业中心进行多学科的专业知识。

In-utero repair of open neural tube defects, lesion closure techniques and the choice of patch 开放式神经管缺损的宫内修复、病变闭合技术及补片的选择
IF 4.1 2区 医学 Q1 OBSTETRICS & GYNECOLOGY Pub Date : 2025-11-07 DOI: 10.1016/j.bpobgyn.2025.102677

In 2011, the landmark Management of Myelomeningocele Study (MOMS) demonstrated unequivocal benefits for children undergoing prenatal closure of myelomeningocele. In addition to reducing the need for CSF diversion following delivery, the procedure was also shown to improve independent ambulation at school age and beyond, typically yielding a functional neurological level at least 2 better than the anatomic level in these patients. While prenatal myelomeningocele (MMC) closure can be more technically challenging and demanding than postnatal closure, the same basic surgical principles are typically employed during fetal intervention to obtain a multi-layered, water-tight closure with recapitulation of the normal anatomic relationships. Here we describe commonly utilized operative techniques for intrauterine MMC closure, with illustration of both open and endoscopic variations to perform the procedure. As maternal-fetal centers across the globe continue to gain experience with intrauterine MMC closure, it is incumbent that we constantly strive to improve both the efficacy and safety of the procedure, mitigating the potential complications of prenatal closure such that the benefits for the child far outweigh the associated risks for both mother and baby.
2011年,具有里程碑意义的脊髓脊膜膨出管理研究(mom)表明,接受产前脊髓脊膜膨出闭合治疗的儿童有明确的益处。除了减少分娩后脑脊液分流的需要外,该手术还显示可以改善学龄及学龄以上儿童的独立行走能力,通常这些患者的功能神经学水平至少比解剖水平好2。虽然产前髓膜脊膜膨出(MMC)闭合在技术上比产后闭合更具挑战性和要求,但在胎儿干预期间通常采用相同的基本手术原则,以获得多层、水密的闭合,并再现正常的解剖关系。在这里,我们描述了宫内MMC闭合的常用手术技术,并介绍了开放式和内窥镜下的手术方法。随着全球母婴中心在宫内MMC闭合方面的经验不断积累,我们有责任不断努力提高手术的有效性和安全性,减轻产前闭合的潜在并发症,使儿童的益处远远超过母亲和婴儿的相关风险。

This article is a comprehensive review of amniotic fluid, its crucial role in fetal development, particularly lung development, and the implications of its deficiency, oligohydramnios. It describes the various causes of fetal renal failure that lead to oligohydramnios, focusing on congenital anomalies of the urinary tract. The text then introduces amnioinfusion, an experimental therapy that involves infusing fluid into the amniotic sac to compensate for the lack of fetal urine production. It details the rationale for this intervention, outlines the different technical approaches employed, and discusses the potential complications and ethical considerations surrounding this experimental therapy. Lastly, the paper summarizes the rationale and design of the RAFT trial, a clinical study that explored the effectiveness and safety of amnioinfusion in the management of early pregnancy renal anhydramnios (EPRA).

Fetal therapy has advanced with novel pharmacological approaches to address congenital tumors and malformations, including cardiac rhabdomyomas and lymphatic malformations (LMs). Cardiac rhabdomyomas, often associated with tuberous sclerosis complex (TSC), can lead to significant morbidity due to arrhythmias, left or right ventricular outflow tract obstruction and heart failure, particularly in neonates. LMs, resulting from abnormal development of the lymphatic system, can cause considerable morbidity, including airway obstruction, disfigurement, recurrent infections, bleeding into cysts, and impaired function of affected organs, depending on location. Recent therapies involving mammalian target rapamycin (mTOR) inhibitors, such as everolimus and sirolimus, offer promising interventions for these conditions. As mTOR inhibitors target dysregulated cell growth and angiogenesis, they can effectively reduce the size of both cardiac rhabdomyomas and LMs in-utero. Clinical studies in the pediatric population have shown that mTOR inhibitors promote regression of cardiac rhabdomyomas, leading to improved cardiac function, and similarly reduce the size of lymphatic malformations, thereby decreasing the need for surgical or interventional procedures. Sirolimus has also shown efficacy in treating complex LMs and is increasingly being used as a first line agent alone as well as in conjunction with other treatment modalities like surgery and sclerotherapy. Despite potential side effects, including gastrointestinal discomfort and an increased risk of infection, the risk–benefit ratio should be carefully evaluated on an individual patient basis. This review examines current evidence supporting the use of mTOR inhibitors in fetal therapy, highlighting their ability to mitigate postnatal complications and improve long-term outcomes. Further research is needed to optimize dosing protocols and assess the long-term safety of these therapies in the fetal population.
胎儿治疗在治疗先天性肿瘤和畸形方面取得了进展,包括心脏横纹肌瘤和淋巴畸形(LMs)。心脏横纹肌瘤常伴有结节性硬化症(TSC),可导致心律失常、左或右心室流出道梗阻和心力衰竭,尤其是新生儿。LMs由淋巴系统异常发育引起,可引起相当大的发病率,包括气道阻塞、毁容、反复感染、囊肿出血和受累器官功能受损,具体取决于部位。最近的治疗涉及哺乳动物靶向雷帕霉素(mTOR)抑制剂,如依维莫司和西罗莫司,为这些疾病提供了有希望的干预措施。由于mTOR抑制剂靶向失调的细胞生长和血管生成,它们可以有效地减小子宫内心脏横纹肌瘤和LMs的大小。儿科人群的临床研究表明,mTOR抑制剂促进心脏横纹肌瘤的消退,从而改善心功能,同样减少淋巴畸形的大小,从而减少手术或介入治疗的需要。西罗莫司在治疗复杂LMs方面也显示出疗效,并且越来越多地作为一线药物单独使用,以及与其他治疗方式(如手术和硬化疗法)联合使用。尽管有潜在的副作用,包括胃肠道不适和感染风险增加,但风险-收益比应在个体患者的基础上仔细评估。这篇综述检查了目前支持mTOR抑制剂在胎儿治疗中使用的证据,强调了它们减轻产后并发症和改善长期预后的能力。需要进一步的研究来优化给药方案,并评估这些疗法在胎儿群体中的长期安全性。

It has been established recently that oral valacyclovir 8g/day reduces significantly the vertical CMV transmission rate in pregnancies with primary Cytomegalovirus (CMV) infection acquired periconceptionally or during the first trimester. Aim of the present study is to expand the result of the previous studies by including any recent cohort study on the topic. MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (Central), the US Registry of clinical trials (www.clinicaltrials.gov) and grey literature sources were searched. Randomized controlled trials and cohort studies administering oral valacyclovir 8g/day in pregnancies with primary CMV infection acquired periconceptionally or during the first trimester were included. Cochrane's Risk of Bias 2 and Robins I tools were used for the risk of bias assessment. The result of amniocentesis was the primary outcome of interest. Two-stages individual patient data meta-analysis was performed and a subgroup analysis was carried out, assessing separately the periconceptional period and the first trimester infections. Four studies were included in the analysis (n = 860 participants). Valacyclovir reduced the vertical transmission rate, adjusted odds ratio (a0R) = 0.39 (95 % CI 0.25–0.59). This reduction was apparent both for periconceptional period aOR = 0.30 (95 % CI 0.13–0.68) and first trimester aOR = 0.47 (95 % CI 0.28–0.78) infections. Valacyclovir also reduced the rate of neonatal infection, a0R = 0.45 (95 % CI 0.25–0.83), both in periconceptional period aOR = 0.42 (95 % CI 0.20–0.90)] and in first trimester aOR = 0.54 (95 % CI 0.29–0.99) infections. Oral valacyclovir (8 g/day) reduces the vertical transmission rates of CMV following primary maternal infection acquired periconceptionally or in the first trimester.
最近已经证实,口服8g/天的valacyclovir可显著降低妊娠期或妊娠早期获得的原发性巨细胞病毒(CMV)感染的孕妇巨细胞病毒(CMV)垂直传播率。本研究的目的是扩大以前的研究结果,包括任何最近的队列研究的主题。检索MEDLINE、Scopus、Cochrane Central Register of Controlled Trials (Central)、US Registry of clinical Trials (www.clinicaltrials.gov)和灰色文献来源。随机对照试验和队列研究包括在妊娠期或妊娠早期获得的原发性巨细胞病毒感染的妊娠中给予口服8g/天的valacyclovir。使用Cochrane's Risk of Bias 2和Robins I工具进行偏倚风险评估。羊膜穿刺术的结果是主要的结局感兴趣。进行两期个体患者数据荟萃分析,并进行亚组分析,分别评估围孕期和妊娠早期感染。四项研究被纳入分析(n = 860名参与者)。伐昔洛韦降低垂直传播率,校正优势比(a0R) = 0.39 (95% CI 0.25 ~ 0.59)。这种降低在围孕期aOR = 0.30 (95% CI 0.13-0.68)和妊娠早期aOR = 0.47 (95% CI 0.28-0.78)感染中都很明显。伐昔洛韦也降低了新生儿感染率,aOR = 0.45 (95% CI 0.25 ~ 0.83),围孕期aOR = 0.42 (95% CI 0.20 ~ 0.90),妊娠早期aOR = 0.54 (95% CI 0.29 ~ 0.99)。口服伐昔洛韦(8g /天)可降低在妊娠期或妊娠早期获得的母体原发性感染后巨细胞病毒的垂直传播率。

Biologics in red cell and platelet alloimmunizations: State of the science and future perspectives 红细胞和血小板同种免疫中的生物制剂:科学现状和未来展望
IF 4.1 2区 医学 Q1 OBSTETRICS & GYNECOLOGY Pub Date : 2025-10-28 DOI: 10.1016/j.bpobgyn.2025.102682

Hemolytic disease of the fetus and newborn (HDFN) is routinely treated with the intrauterine transfusion (IUT) of compatible donor red cells once fetal anemia is detected. Intravenous immune globulin (IVIG) is often used in patients with a previous history of early onset disease in a previous pregnancy. Although IUT's are still required in the majority of these pregnancies, IVIG appears to prolong the gestational age until these are necessary. IVIG with or without oral steroids is utilized in most countries to prevent thrombocytopenia and intracranial hemorrhage in cases of fetal/neonatal alloimmune thrombocytopenia (FNAIT). Nipocalimab, a humanized monoclonal antibody that blocks the neonatal Fc receptor, is currently undergoing clinical trials in both HDFN and FNAIT as a potential new form of immunotherapy for these alloimmune disorders of pregnancy.
一旦检测到胎儿贫血,胎儿和新生儿溶血性疾病(hddn)的常规治疗是宫内输血(IUT)相容供体红细胞。静脉注射免疫球蛋白(IVIG)常用于既往妊娠有早发性疾病史的患者。尽管大多数孕妇仍然需要宫内节育器,但IVIG似乎延长了胎龄,直到有必要这样做。在大多数国家,IVIG联合或不联合口服类固醇用于预防胎儿/新生儿同种免疫性血小板减少症(FNAIT)患者的血小板减少症和颅内出血。Nipocalimab是一种人源化单克隆抗体,可阻断新生儿Fc受体,目前正在HDFN和FNAIT中进行临床试验,作为治疗这些妊娠同种免疫疾病的潜在新形式。

Twin-to-Twin Transfusion Syndrome (TTTS) occurs in about 15 % of monochorionic twin pregnancies, less frequently does it occur prior to 18 weeks of gestation. When occurring early, this severe complication presents unique diagnostic and management challenges. In this review we will focus on the pathophysiological mechanisms underlying early TTTS. We will be emphasizing the role of placental vascular anastomoses and hemodynamic imbalances in disease progression. Advances in imaging techniques allow early diagnosis of the disease, impacting on consultation and clinical decision-making. Current treatment strategies, specifically including fetoscopic laser photocoagulation, are reviewed with a focus on optimizing perinatal outcomes. By integrating insights from fetal physiology, diagnostic innovations, and therapeutic advancements, this review aims to refine clinical management approaches to improve survival and morbidity outcomes for monochorionic twin pregnancies complicated by early TTTS.
双胎输血综合征(TTTS)在单绒毛膜双胎妊娠中发生约15%,在妊娠18周之前发生的频率较低。当早期发生时,这种严重的并发症提出了独特的诊断和管理挑战。在这篇综述中,我们将重点讨论早期TTTS的病理生理机制。我们将强调胎盘血管吻合和血流动力学失衡在疾病进展中的作用。影像技术的进步使疾病的早期诊断,影响咨询和临床决策。目前的治疗策略,特别是包括胎儿镜激光光凝,重点是优化围产期结果进行了回顾。通过整合胎儿生理学、诊断创新和治疗进展的见解,本综述旨在改进临床管理方法,以提高合并早期TTTS的单绒毛膜双胎妊娠的生存率和发病率。

From concept to practice: Screening for fetal and neonatal alloimmune thrombocytopenia (FNAIT) 从概念到实践:筛查胎儿和新生儿同种免疫性血小板减少症(FNAIT)。
IF 4.1 2区 医学 Q1 OBSTETRICS & GYNECOLOGY Pub Date : 2025-10-27 DOI: 10.1016/j.bpobgyn.2025.102683

Affecting 1 per 1000 to 2000 pregnancies, Fetal and Neonatal Alloimmune Thrombocytopenia (FNAIT) is the leading cause for (severe) thrombocytopenia in term neonates. Due to an incompatibility between fetal and maternal platelets, maternal alloantibodies are formed against paternally derived human platelet antigens (HPAs). The alloantibodies can cross the placenta into the fetal circulation, where they can destruct the fetal platelets. As a result, severe thrombocytopenia may occur, potentially leading to intracranial hemorrhage (ICH) or severe organ bleeding during pregnancy or shortly after birth. In the absence of a universal prenatal screening program focussed on HPA-1a, FNAIT is often diagnosed too late, typically after the onset of severe fetal or neonatal bleeding complications. A screening program could be very effective in identifying the first pregnancy complicated with FNAIT, allowing timely intervention and prevent severe ICH and its associated long-term permanent sequelae. The aim of this review is to provide a comprehensive overview of the existing evidence regarding a possible future screening program for FNAIT. Additionally, challenges will be explored that need to be addressed for successful implementation of a screening program.
胎儿和新生儿同种免疫性血小板减少症(FNAIT)影响每1000至2000例妊娠中有1例,是足月新生儿(严重)血小板减少症的主要原因。由于胎儿和母体血小板之间的不相容,母体同种抗体形成对抗父源性人血小板抗原(HPAs)。同种异体抗体可以穿过胎盘进入胎儿循环,在那里它们可以破坏胎儿的血小板。因此,严重的血小板减少可能发生,潜在地导致颅内出血(ICH)或严重的器官出血在怀孕期间或出生后不久。由于缺乏针对HPA-1a的普遍产前筛查计划,FNAIT通常被诊断得太晚,通常是在出现严重的胎儿或新生儿出血并发症之后。筛查程序可以非常有效地识别首次妊娠合并FNAIT,允许及时干预并预防严重的脑出血及其相关的长期永久性后遗症。本综述的目的是对现有证据进行全面概述,以确定未来可能的FNAIT筛查方案。此外,还将探讨为成功实施筛查计划而需要解决的挑战。
