How is renal artery stenosis caused?

summary

Renal artery stenosis is a kind of renal vascular disease caused by a variety of causes. The main clinical manifestations are renal vascular hypertension and ischemic nephropathy. As long as the renal artery stenosis or obstruction is removed in time and the diseased blood vessels are unobstructed again, hypertension can be cured and renal dysfunction can be reversed. How is renal artery stenosis caused? Next, I'd like to share my views with you.

How is renal artery stenosis caused?

Renal artery stenosis is often caused by atherosclerosis and fibromuscular dysplasia. In China and Asia, it can also be caused by Takayasu arteritis. Atherosclerosis is the most common cause, accounting for about 80% of patients with renal artery stenosis, mainly in the elderly, while the latter two causes are mainly in young people, mostly women

Renal artery stenosis often causes renovascular hypertension, which is due to renal ischemia stimulated renin secretion, renin angiotensin aldosterone system (RAAS) activation, peripheral vasoconstriction, and * retention of water and sodium.

Renal artery stenosis caused by atherosclerosis and Takayasu arteritis can also cause ischemic kidney disease. Renal ischemia on the affected side can lead to glomerulosclerosis, renal tubular atrophy and renal interstitial fibrosis.

matters needing attention

The key of prevention is to prevent and treat the primary disease of renovascular hypertension, such as Takayasu arteritis; Atherosclerosis, etc. The establishment of good living habits is an important measure to prevent the disease. Reasonable diet, moderate exercise, no smoking and alcohol, regular life, keep the mood relaxed, active treatment of primary diseases, can play a role in the prevention of the disease
