Presence Of Air In The Hepatic Portal System In Association With Umbilical Venous Catheter Malposition [presença De Ar No Sistema Porta Hepático Associada A Cateter Umbilical Venoso Mal Posicionado]

The authors report a case of umbilical venous catheter malposition with air in the portal venous system in a preterm neonate. Initially, the hypothesis of necrotizing enterocolitis was considered, but the newborn progressed with no finding of disease and the air disappeared at follow-up radiography. The differential diagnosis of such a finding can avoid unnecessary clinical treatments. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.4714950Butler-O'Hara, M., Buzzard, C.J., Reubens, L., A randomized trial comparing long-term and short-term use of umbilical venous catheters in premature infants with birth weights of less than 1251 grams (2006) Pediatrics, 118, pp. e25-e35Schlesinger, A.E., Braverman, R.M., Dipietro, M.A., Pictorial essay.
