Renal artery stenosis is a disease in which renal artery get narrow due to fibromuscular dysplasia or atherosclerosis. In this state renal artery can impede blood flow and leads to renal failure. Now we will talk about that what is renal- renal means anything related to kidney so renal arteries are those arteries, which carries blood from the heart to kidney. These arteries extend to kidney and it purifies this blood. When the diameter of the renal artery is decreased then in this state arties cannot carry the right amount of blood and kidney stops its proper functioning that leads to kidney failure and causes many problems.

There are many important causes of renal artery stenosis but some of the most important are :–

  • Atherosclerosis
  • High blood pressure
  • Smoking
  • Diabetes
  • High cholesterol
  • Age
  • Dissection- when the blood walls are divided

Renal arteries are very essential for the kidney as the major function of these arteries is to provide blood to the kidneys. Renal arteries are present above the renal veins. There may be two or more than two arteries serving each kidney. The arteries present in the kidney are the pair of large blood vessel that branch from the abdominal aorta to the kidneys. At the inner concavity present in the each kidney there is an opening that is called Hilum and it is the place from where the renal arteries passes. If the functioning of arteries blocked due to any disease, that result in harming the kidney

Diseases in renal arteries are caused when the plaque is buildup in the arteries that leads to the kidneys. Now it is necessary to understand the term plaque so plaque is a mixture of cholesterol and fats and it make the arteries stiffen and narrow when it accumulates in the renal arteries. It tends to block the blood flow in the kidney. Those obstructions that are caused due to this are also called artery stenosis. This all lead to many problems in human body like kidney failure, congestive heart failure and high blood pressure. (more…)
