Case Study
The article presents the case study of a 22-year-old woman, who was suffering from stenosis of renal artery. She had hypertension for one year. Her only symptom was an occasional headache. The electrocardiogram was normal. Renal scanning showed less uptake of the tracer in the left kidney than in the right. The patient was then given 25 mg of captopril orally, and renal scanning was repeated one hour later. The scintigraphic images also suggested the presence of stenosis of the left renal artery. Angiography revealed stenosis in the midportion of the left renal artery and in the anterior division of the left renal artery. The patient's blood pressure returned to normal within three hours of angioplasty and has remained normal for three years.
