Evaluation of the Presence of Hereditary and Acquired Thrombophilias in Brazilian Children and Adolescents With Diagnoses of Portal Vein Thrombosis

Abstract

Even after investigation of main hereditary and acquired thrombophilia, PVT remains without apparent cause in most patients. Nevertheless, association of local and systemic risk factors seems to be important also in the pediatric age group. Therefore, despite the low prevalence, a complete investigation, which includes both hereditary and acquired thrombophilias, may be necessary.
