Know the Facts
Renovascular conditions are various conditions that can affect the renal arteries and veins. When the renal arteries become blocked and your kidneys do not receive enough blood or oxygen, this is a condition called renal artery stenosis. These arteries can also be affected by a number of diseases, most commonly atherosclerosis. Less common conditions that may occur in the renal arteries include: renal artery aneurysms, fibromuscular dysplasia (FMD) and vasculitis (inflammation of the arteries). Renovascular disease may cause kidney damage, renal failure and high blood pressure.
Symptoms
Often there are no symptoms of blocked kidney arteries. Severe high blood pressure can lead to heart problems, stroke or other severe medical issues including aneurysms and aortic dissection. Dialysis may be needed if the damage becomes severe. Flank pain or blood in urine may be a sign of vasculitis, fibromuscular dysplasia and renal artery aneurysms.
Diagnosis
Duplex Ultrasound, MRA, CTA, angiogram
Treatment
Lifestyle modifications, renal angioplasty, surgical revascularization (bypass surgery)
