Renal artery bypass grafting is indicated to control symptoms of renal artery stenosis and prevent complications. The patients most often indicated for renal vascular intervention are those with severe renal artery stenosis — greater than 60 to 70% of the artery's diameter.

Renal artery stenosis is a narrowing of one or more of the arteries that carry blood to the kidneys (renal arteries). This results in reduced blood flow to the kidneys, which can lead to high blood pressure and damage to kidney tissue.

High blood pressure is a common symptom of renal artery stenosis. If not detected early and treated promptly, high blood pressure due to renal artery stenosis can cause dangerous complications, even stroke leading to death.

Renal angiography, also known as renal arteriography, uses X-rays to image the blood vessels of the kidneys while injecting contrast material into the blood vessels of the kidneys. This technique is used to detect signs of blockage or narrowing of the renal arteries or abnormalities that affect the ability to supply blood to the kidneys. So what are the specific kidney diseases?

Renal artery stenosis is a common disease of the arteries supplying blood to the kidneys. This is a peripheral artery disease, with a common cause of atherosclerosis but a lower incidence than diseases of the arteries in other locations. However, due to the equally serious consequences that can be caused, renal artery angioplasty and stenting are common interventions to correct this condition.

Color Doppler ultrasound in renal artery stenosis helps diagnose the cause of hypertension due to renal artery stenosis. In addition, long-term renal artery stenosis can lead to kidney failure. Therefore, renal artery stenosis needs to be diagnosed and treated early.

The function of the kidneys is to clean the blood and keep the body's fluids and electrolytes in balance. Blood in the circulatory system is carried to the kidneys through the renal arteries. When you have renovascular disease, the arteries can become narrowed or blocked. As a result, the body's important blood filtering system is damaged, causing high blood pressure and/or kidney failure.

Renal artery Doppler ultrasound is a widely used paraclinical diagnostic method today to serve the screening, diagnosis and monitoring of renal artery hypertension as well as a number of other related diseases.

Renal artery stenosis is caused by many different factors. The two most common forms of renal artery stenosis are: Fibromuscular dysplasia and atherosclerosis. If renal artery stenosis is not detected early and treated promptly, it will cause dangerous complications.

Renal artery stenosis will progress gradually as the atherosclerotic plaque increases in size, reducing blood flow to the kidney and impairing kidney function. At this time, renal artery intervention by balloon angioplasty and percutaneous renal artery stenting is the preferred method of revascularization.

The complication of renal artery stenosis is kidney failure, from which the patient needs dialysis or even a kidney transplant. These complications often progress for a long time, so patients have the opportunity to intervene by early detection, aggressive treatment, and lifestyle changes before the disease becomes serious.
