In the presence of renal artery stenosis, the resistance in the afferent arteriole is increased. As compensation, Angiotensin II acts to constrict the efferent arteriole in order to achieve adequate profusion of the glomerulus. ACE inhibitors block the conversion of angiotensin I into angiotensin II. Without its vasoconstrictive effect, the efferent arteriole becomes dilated. This leads to a drop in GFR and may lead to renal failure.
Treatment for renal artery stenosis is either surgical, pharmaceutical, or with angioplasty or stenting.
The two main causes of renal artery stenosis are atherosclerosis and fibromuscular disease.
Renal arterial stenosis has no overt symptoms. Eventually, untreated renal arterial stenosis causes secondary complications such as chronic kidney failure,
Untreated renal artery stenosis can cause hypertension (high blood pressure) and may ultimately lead to chronic kidney failure (end-stage renal disease).
congenital renal artery stenosis
my 70 year old mother was on ace inhibitors ,arb's and diuretics.could she still develop flash pulmonary edema due to renal artery stenosis?she was a diabetic.
The Renal Vein is a vein that leads away from the kidney. The Renal Artery is the Artery that leads towards the kidney.
The Renal artery attaches to the Kidneys.
The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea
Renal Artery
The renal artery brings oxygen to the kidneys.
Yes the renal artery serves the kidney
