This condition may result in secondary hypertension and secondary hyperaldosteronism. Other possible features include:
- coexistant cerebrovascular, cardiovascular or peripheral vascular disease
- deterioration of renal function following treatment with ACE inhibitor
- abdominal bruit; signs of coexistant vascular disease e.g. carotid or femoral bruit; absent peripheral pulses
A small kidney will be seen on intravenous urography on the affected side with a delayed and persistent nephrogram.
In consideration of computed tomographic angiography and magnetic resonance angiography (MRA) in comparison to digital subtraction angiography (DSA) in diagnosis of renal artery stenosis (1):
- computed tomographic angiography and MRA are not reproducible or sensitive enough to rule out renal artery stenosis in hypertensive patients
- DSA is the diagnostic method of choice
