Whether renal artery stenosis is serious or not is related to the degree of stenosis. Generally, stenosis of less than 50% is not considered serious, but if it is more than 50%, it is more serious.
Renal artery stenosis is often caused by fibromuscular dysplasia as well as atherosclerosis, which mainly manifests as renal vascular hypertension and ischemic nephropathy.
If the degree of stenosis is less than 50%, it usually has little effect on the blood flow of the kidneys, which is not a very serious condition, and the prognosis is good after active treatment.
If the degree of stenosis is more than 50%, it is a more serious condition, which will easily lead to insufficient blood supply to the kidneys, and will gradually deteriorate the renal function if it is in chronic ischemia for a long time. Generally, it needs to be treated by angioplasty, endarterectomy, bypass grafting and other surgeries.
Patients with renal artery stenosis should go to the hospital in time and actively cooperate with doctors for treatment to avoid delay.
