Radiation-induced renovascular hypertension successfully treated with transluminal angioplasty: case report.

Severe hypertension and stenosis of the right renal artery developed in a 21 year old male, 14 years after completion of inverted Y radiation (4000 rads) for abdominal Hodgkin's disease. Transluminal angioplasty resulted in improvement of the right kidney function, and normalization of the blood pressure for one year. Subsequently, the patient required only minimum medical therapy for blood pressure control. Transluminal angioplasty may be effective immediately in the treatment of radiation induced renal artery stenosis, although long term success remains uncertain.
