Umbilical artery catheterisation is considered the standard
of care for arterial access in neonatal intensive care unit. It
is routinely used for blood sampling and blood pressure
monitoring. Unfortunately, an indwelling umbilical catheter
have been associated with thrombotic complication which
may result in either partial or complete occlusion of the
aorta. We report here our experience in the diagnosis and
treatment of a neonate with this condition.
