Radiation injury to abdominal aorta and iliac artery sustained in infancy.

Late complications of radiation therapy will become more common as treatment of neoplasms in childhood becomes more successful. A patient with a successfully treated Wilm's tumour presented with hypertension 3 years after therapy. Angiography revealed extensive damage to the aorta and left common iliac artery, probably caused by the radiation therapy. The hypertension was the result of renal artery stenosis.
