A 56-year-old female patient came at the end of August to the office due to uncontrolled hypertension. Since she was a thin person without a family history of persistant hypertension, suspicion of secondary hypertension was induced and advised for biochemical end imaging tests. The final diagnosis was renovascular hypertension, the most common cause of secondary hypertension. Renal arteriography indicated a 99% stenosis to the left and the patient underwent a successful stent implantation. After angioplasty, blood pressure returned to normal and the patient did not receive medication. Invasive therapy is recommended for resistant hypertension (at least 4 antihypertensive drugs), aggravation of renal function and patients with flash pulmonary edema or congestive heart failure with preserved ejection fraction (EF).
