[2] de Veber GA, MacGregor D, Curtis R, Mayank S. Neurologic outcome in survivors of childhood arterial stroke and sinovenous thrombosis. Its pathophysiology is not clear. According to a recent study, delayed presentation was a predictor of the development of cerebral palsy eventually.In general, patients with a large stroke size and involvement of certain structures (e.g. Het arterieel cerebraal infarct bij de pasgeborene. Neurology. Thrombosis in the Development of Newborn Brain Damage. By continuing you agree to the use of cookies. organization. None received thrombolytic therapy. [1] Chalmers EA. The evaluation and management of postnatal thromboses. Only 5 (16.6%) patients had an abnormal result: Protein C deficiency in two cases, factor V Leiden heterozygous mutation in one case, positive lupus anticoagulant in one case, and high antiphospholipid IgM antibodies in one case (Table 3). Although contributing a substantial share of neurological morbidity in children, PAS occurs at a rate of 1 in several thousand term births, presenting a logistic problem in study design. Martinez-Biarge, M, Cheong, JL, Diez-Sebastian, J, Mercuri, E, Dubowitz, LM, Cowan, FM. Significant risk factors in the univariate analysis (P < 0.05) were primiparity, stillbirth, neonatal sepsis, asphyxia, twin pregnancy, placenta abruption, emergency cesarean section, Apgar score ≤7 after 5 min, breech presentation, and hyperbilirubinemia. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. (Table 1). Login failed. PAS has been described chiefly in term or near-term infants. A recent study in the U.S. reported the percentage of the population affected with perinatal stroke at a given time to be 20 in 100,000 live births. If you have the appropriate software installed, you can download article citation data to the citation manager of your choice. The role of anticoagulant therapy in the management of neonatal SVT remains controversial and there are no clinical trials available on which to base recommendations for management at this time. Find and book a doctor, dentist, physio and more on HealthEngine. Perinatal ischemic stroke is not rare in term and near-term infants and is an important antecedent of long-term neurological disability, including congenital hemiplegia (hemiplegic cerebral palsy) and seizure and cognitive disorders. Lee, J, Croen, LA, Backstrand, KH, Yoshida, CK, Henning, LH, Lindan, C, Ferriero, DM, Fullerton, HJ, Barkovich, AJ, Wu, YW. Schulzke, S, Weber, P, Luetschg, J, Fahnenstich, H. de Vries, LS, Groenendaal, F, Eken, P, van Haastert, IC, Rademaker, KJ, Meiners, LC. The incomplete collection of the thrombophilia study is a major limitation, owing primarily to the retrospective nature of the study and subject collection for many years, during which testing options changed regularly. Currently the ACCP guidelines recommend the use of either UFH or LMWH only for neonates without large ischaemic infarctions or intracerebral haemorrhage because of the risk of bleeding. The following risk factors are significantly associated with neonatal arterial stroke: primiparous mother, emergency cesarean section, asphyxia, and Apgar score ≤7 after 5 min. Access to society journal content varies across our titles. Full clinical data were collected from cases and control patients, including age of presentation, gender, neuroimaging, and thrombophilia study. For perinatal strokes, the overall risk for another stroke is very low, less than one percent. In the majority of cases detailed thrombophilia screening in perinatal stroke will not affect management and at this time should be restricted to the exclusion of major abnormalities. Cranial ultrasonography, the most widely used form of neuroimaging in the nursery period, is not a sensitive detector of stroke.

Three subcategories were defined: fetal ischemic stroke, neonatal arterial ischemic stroke (NAIS), and presumed perinatal ischemic stroke (PPIS). Also, equivalent information of thrombophilia studies is not available for the controls. A detailed antenatal and perinatal history was obtained at the time of the referral (cases) or recruitment (controls) from obstetric and neonatal notes. The American Stroke Association and the International Alliance for Pediatric Stroke have collaborated to provide these resources: ASA’s Scientific Statement on the Management of Stroke … Primiparous pregnancies have also recently been identified as a risk factor for neonatal stroke24,25. Although described earlier than inherited thrombophilias, maternal antiphospholipid antibody disorders have been less investigated for their role in PAS, perhaps because of absence of consensus as to which of the several antiphospholipid antibodies are most important for study and because of lack of standardization of assays. This would, of course, be logistically difficult, but the information provided would be invaluable in the understanding of the multifactorial pathway of neonatal stroke. ... Congenital heart disease and blood clotting disorders are both common risk factors for perinatal strokes, but in many cases, they can be linked to a birth injury. Clinical data of patients with PAIS diagnosis were analyzed. Evaluation and Management of Stroke in the Neonate. Some society journals require you to create a personal profile, then activate your society account, You are adding the following journals to your email alerts, Did you struggle to get access to this article? The likely outcomes in the neurological system are: Treatment largely aims at preventing further clotting. Statement of Informed ConsentStatement of Informed Consent was obtained written from legally authorized representatives. Although there was no reported morbidity or mortality from bleeding related to the use of anticoagulant agents it is not possible to say whether infants who received anticoagulant therapy had a better outcome than those who did not. The results showed a male predominance (66.7%). Although the evidence is less than complete or entirely in agreement, it seems likely that maternal and perhaps infant thrombophilias can lead to complications of pregnancy, such as prior fetal death, preeclampsia, abruptio placentae, placental vasculopathy, and fetal growth restriction,18 which are in turn risk factors for neonatal encephalopathy, stroke, or cerebral palsy. A recent study in a national inpatient sample10 reported risk factors for pregnancy-related stroke to include postnatally identified infection (odds ratio [OR] 25); migraine (OR 16.9); thrombophilia, including history of thrombosis and the antiphospholipid syndrome (OR 16.0); systemic lupus (OR 15.2); heart disease (OR 13.2); preeclampsia (OR 4.4); diabetes (OR 2.5); and smoking (OR 1.9). For more information view the SAGE Journals Sharing page. It is an increasingly recognised cause of neurological disabilities such as cerebral palsy, epilepsy, and cognitive abnormalities 3. How to tackle bleeding and thrombosis in the newborn. The placenta, which has its own hemostatic mechanisms, is probably an important locus of pathology in PAS. The disorder involves a range of medical specialists, the literature is scattered, and the methodology of many of the studies is suboptimal. PAS is a cerebrovascular event occurring during fetal or neonatal life, before 28 days after birth, with pathological or radiological evidence of focal arterial infarction of brain. Factor V Leiden and Antiphospholipid Antibodies in Either Mothers or Infants Increase the Risk for Perinatal Arterial Ischemic Stroke. The need for further research is clear. The 2 periods of life in which the risk of having a stroke is highest are in the elderly and in the fetus or newborn infant. Some perinatal ischemic strokes will be symptomatic during the neonatal period, while others may not be recognized for months or years, or never be diagnosed if they do not develop enough symptoms to suspect a stroke7. Objective The incidence of perinatal arterial ischaemic stroke (PAIS) is about 1 in 2300 live births. The rate of occurrence of new cases of perinatal stroke is about 93 in 100,000 live births. In four cases, cranial ultrasound suggested neonatal arterial territory cerebral infarction.
