Figure 5: Percutaneous transluminal angioplasty in a 3-month-old infant with left renal artery and malignant systemic hypertension (Case 18) (a) The right femoral artery was used demonstrating the short stenotic lesion, almost complete (95%) when compared to the diameter of the adjacent healthy segment of the left renal artery (white arrow) and steep angle of branching of the artery from the descending aorta. (b) The catheter advanced from the right carotid artery, mounting a 1.5 mm balloon, was passed across the site of stenosis and inflated until the waist of the balloon disappeared. (c) After the angioplasty, the ratio of stenosis was reduced from 95% to 30%
