RESUMO
Neonates, particularly critically ill and premature infants, have one of the highest risks of thromboembolic complications, particularly venous thromboembolism (VTE), in the pediatric population. Recent data suggest that the incidence of VTE has significantly increased in neonates over the last few decades. Critically ill and premature infants exhibit multiple risk factors that place them at a high risk for thromboembolic events including developmental hemostasis, propensity to infections, and frequent need for central venous access. The clinical presentation, diagnostic modalities, and treatment strategies for thromboembolic complications in neonates vary based on several factors, including the etiology of the thromboembolic event, the anatomic site affected, and the patient's underlying comorbidities. Although guidelines for management are available, they are mostly based on consensus recommendations and on extrapolation from adult data due to a lack of high-quality data in the neonatal population. Current guidelines recommend anticoagulation for specific scenarios. More studies are necessary to elucidate optimal management strategies for newborns with thromboembolic complications.
