Umbilical artery catheter use complicated by pseudoaneurysm of the aorta.
We report a case of a large aortic mycotic pseudoaneurysm in a premature infant, a rare but serious complication associated with sepsis and umbilical artery catheter (UAC) use. Sonography is an appropriate first-line imaging modality for detection of aortic pseudoaneurysms. Increased awareness of this rare complication may lead to earlier diagnosis in the high-risk premature infant with a history of a UAC and sepsis.
