Malpositioned umbilical catheters
Updates to Case Attributes
Neonate in NICU with radiograph of chest and abdomen showing malpositioned umbilical arterial and venous catheters.
Umbilical arteryarterial catheter (identified by inferior looping of the catheter from the umbilicus to pass through internal iliac artery into aorta) can be placed in high (D6 to D9 vertebral levels) or low (below inferior mesenteric artery) positions in the aorta to avoid mesenteric or renal arterial placement. It is usually placed in a high position.
Malposition of the arterial catheter into aortic branches can lead to thrombosis or dissection.
Umbilical venous catheter (identified by more linear course from the umbilical vein into IVC) is ideally placed with its tip in IVC at the level of the diaphragm. The catheter has to pass from umbilical vein into left portal vein, ductus venosus, hepatic vein and then in IVC.
Malposition into hepatic or portal vein can cause thrombosis. Malposition into right atrium can induce arrhythmias. Perforation of portal vein can cause haemorrhage.
