This condition is commonly associated with fatal outcome if prenatally undiagnosed. Two types of vasa previa have been classically described, associated with well-established risk factors. However, a rare third type of vasa previa has also been reported. Case: We present a case of type 3 vasa previa diagnosed in the second trimester, with two fetal vessels overlying the cervix. The placenta was unilobed, not previa, and the cord insertion was marginal. Placental examination after delivery confirmed the prenatal findings. Conclusion: This case suggests that vasa previa can occur in the absence of cord or placental anomalies. A review of vasa previa classification and screening strategies for this condition is needed.","author":[{"@context":"https://schema.org","@type":"Person","name":"Cristina

Vasa previa is generally classified into types I and II. However, some cases are difficult to classify, and some studies have proposed a type III classification. This study aimed to review the current evidence on type III vasa previa. A systematic literature search was conducted, and 11 articles (2011–2022) were included. A systematic review showed that type III vasa previa accounts for 5.7% of vasa previa cases. Thirteen women with type III vasa previa were examined at a patient-level analysis. The median age was 35 (interquartile range [IQR] 31.5–38) years, and approximately 45% were assisted reproductive technology (ART) pregnancies. The median gestational week of delivery was 36 (IQR 34–37) weeks; the antenatal detection rate was 84.6%, and no cases reported neonatal death.

Methods: Placental types of vasa previa were defined as follows: Type 1, vasa previa with velamentous cord insertion and non-type 1, vasa previa with a multilobed or succenturiate placenta and vasa previa with vessels branching out from the placental surface and returning to the placental cotyledons. Results: A total of 55 cases of vasa previa were included in this study, with 35 cases of type 1 and 20 cases of non-type 1. Vasa previa with type 1 showed a significantly higher association with assisted reproductive technology, compared with non-type 1 (p = 0.024, 60.0% and 25.0%, respectively). The diagnosis was significantly earlier in the type 1 group than in the non-Type 1 group (p = 0.027, 21.4 weeks and 28.6 weeks, respectively).

Vasa previa is a rare obstetric complication, with a reported incidence of 1 per 2500 pregnancies.1 This condition has been associated with high fetal mortality (60%) due to rapid fetal exsanguination at the time of membrane rupture. Vasa previa has been classified into two types based on its pathologic appearance: type 1 occurring as a result of a velamentous cord insertion into the placenta and type 2 as a result of freely coursing fetal vessels connecting a main placental plate with a succenturiate lobe.2 Andrei Rebarber, MD, Cara Dolin, MD, Nathan S.

Rupture of the membranes leads to fetal exsanguinations and even neonatal death. The fetal mortality from undiagnosed vasa previa ranges from 60-70%. It is the unexpected manner in which sudden fetal demise occurs that makes this complication one of the most dreaded and challenging events in modern obstetrics. However, the advent of ultrasonography in obstetric practice has made the diagnosis possible prenatally as early as second trimester. We present here a case of vasa previa which was successfully managed at our institute.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline

cervical os or lying close to it. When vasa previa is not detected during antenatal period, the perinatal outcome could be grievous. Ultrasound is the modality of choice in detection of vasa previa. Despite the increasing availability of ultrasound in modern times, its use in diagnosing vasa previa still remain very low in Africa. We present the sonographic findings and perinatal outcomes of three cases of vasa previa which were detected antenatally within a period of nine months in an African setting.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Antenatal diagnosis of vasa previa: report of three cases in an African setting Antenatal diagnosis of vasa previa: report of three cases in an African setting","attachmentId":65265262,"attachmentType":"pdf","work_url":"https://www.academia.edu/44774250/Antenatal_diagnosis_of_vasa_previa_report_of_three_cases_in_an_African_setting_Antenatal_diagnosis_of_vasa_previa_report_of_three_cases_in_an_African_setting","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/44774250/Antenatal_diagnosis_of_vasa_previa_report_of_three_cases_in_an_African_setting_Antenatal_diagnosis_of_vasa_previa_report_of_three_cases_in_an_African_setting"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":102993073,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":102993073,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_102993073" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
