Initial treatment for renal artery stenosis involves the use of several medications to help control hypertension. Monitoring the patient is an essential part of the treatment plan to ensure that the blood pressure is lowered. In some cases, a surgical operation may be required to remove the damaged kidney, as stated by WebMD.
If medication fails, there are several treatment options that a doctor may recommend, including medical therapy and medical procedures, such as surgical treatment, renal angioplasty, bypass procedure and endarterectomy. These procedures may be recommended by a doctor if the narrowing of the renal artery gets worse, medication fail to control blood pressure and if the condition of the kidneys is worsening, as reported by MedlinePlus. Lifestyle changes are also necessary things to consider during treatment. Eating a healthy diet, taking regular exercise, limiting alcohol intake, overcoming stress, maintaining a healthy weight and quitting smoking are some of the things taken into account.
Also referred to as renal hypertension, renal artery occlusion or renovascular hypertension, renal artery hypertension is caused by a condition called atherosclerosis, which is an accumulation on the walls of the blood vessels. Although it is rare, renal artery hypertension can also be caused by a condition called fibromuscular dysplasia, which is irregular growth of the cells in the arteries, as noted by WebMD.
