Answer:
Narrowing of the renal artery is considered a major cause of decreased blood flow through the renal arteries.
Explanation:
Narrowing of the renal artery causes renal artery stenosis and is considered to be primarily responsible for decreased blood flow through the renal arteries. This narrowing is caused by thromboembolism or fibromuscular dysplasia. This disease can cause chronic renal failure and treatment is done through surgical revascularization.
