Visceral aortic aneurysm in a 4 1/2-year-old child: an unusual complication of umbilical artery catheterization.

A 4 1/2-year-old girl had a 2.2 cm in diameter abdominal aortic pseudoaneurysm extending from above the celiac artery to 4 cm above the aortic bifurcation. This lesion developed after umbilical artery catheterization in the neonatal period, which also resulted in thrombosis of the right renal artery and renal atrophy. Patch graft angioplasty with polytetrafluoroethylene (Gore-Tex) was performed after excision of the aneurysm via a retroperitoneal approach.
