Pseudoaneurysm formation after umbilical arterial catheterization


Intravenous literature: So, M.J., Kobayashi, D., Anthony, E. and Singh, J. (2012) Pseudoaneurysm formation after umbilical arterial catheterization: an uncommon but potentially life-threatening complication. Journal of Perinatology. 32(2), p.147-149.


Relatively straightforward placement of an umbilical arterial catheter can be complicated by psuedoaneurysm formation in the presence of a coagulopathy. We describe a case of a neonate, where bedside ultrasound had a key role in the timely diagnosis of this complication and prevented a potentially fatal outcome. Pertinent imaging findings are described with a brief literature review.
