title: False aneurysm of the descending aorta: a complication of umbilical artery catheterization.
abstract: A patient had an aneurysm of the descending aorta secondary to aortitis arising from umbilical artery catheterization and in association with coarctation of the aorta. The aortitis probably was the direct result of bacterial contamination of the umbillicus and catheter with Staphylococcus aureus and the placement of the catheter tip just distal to a coarctation of the aorta. The patient required surgical resection of the coarctation and aneurysm of the descending aorta and placement of a tubular Dacron graft at 6 month of age. This is, to our knowledge, a hitherto unreported complication of umbilical artery catheterization.
