Multifactorial Neonatal Thrombosis in Inferior Vena Cava Dislodged to the Right Atrium: A Case Report

Neonatal thrombotic diseases can cause mortality or serious morbidity and disability.

In this report, we present a case of neonatal inferior vena cava thromboembolism with several underlyingfactors. Hereditary thrombophilia and genetic mutation in plasminogen activator inhibitor-1 and MTHFR A1298C genesin conjunction with cleft palate resulted in poor lactation and hypernatremic dehydration. A peripherally insertedcentral catheter in the inferior vena cava was an additional underlying factor. Thrombosis mass was dislodged to theright atrium while asymptomatic and accidentally detected during routine echocardiography.

Surgical thrombectomy was done successfully, and the mass was removed from the right atrium.
