Hypertension can be classified into primary or secondary hypertension according to the etiology. Renovascular hypertension is a common cause of secondary hypertension. It is usually found in patients with old age, diabetes, hyperlipidemia, stroke or coronary heart disease. Early identification of renovascular hypertension allows specific intervention (e.g. renal artery stenting) which may improve the blood pressure control of the patient.
Some hypertensive patients suffer from renal artery stenosis. Renal arteriography is still an important diagnostic method which is a crucial investigation in patients with difficult-to-control blood pressure.
Methods of Examination:
1. Hypertension Screening (Plain): Adrenals + Kidneys & Renal MRA
2. Hypertension Screening (Contrast) : Adrenals + Kidneys & Renal MRA
