What are the possible complications of RAS?
Occlusion and stenosis of unspecified carotid artery
Renal artery stenosis (RAS) is the narrowing of one or both renal arteries. “Renal” means “kidney” and “stenosis” means “narrowing.” The renal arteries are blood vessels that carry blood to the kidneys from the aorta—the main blood vessel that carries blood from the heart to arteries throughout the body.
Disease of the arteries that supply blood to the kidneys – a condition known as renal artery stenosis – is less common than the more familiar form of atherosclerosis, peripheral arterial disease, but is equally serious.
Background: Renal dysfunction is an important factor of cardiovascular risk. Renal artery stenosis (RAS) is a potential cause of secondary hypertension and by renal ischemia may lead to progressive renal insuficiency.
Atherosclerotic renal artery stenosis (RAS) is a cause of severe hypertension, pulmonary edema and renal dysfunction. Recent studies have shown a high prevalence of RAS in patients with peripheral arterial disease (PAD) or coronary heart disease (CHD).
It is important to realize that any condition that compromises blood flow to the kidneys can contribute to renovascular hypertension. [3] The most common causes of renovascular hypertension include: Renal artery stenosis (RAS), mostly secondary to atherosclerosis.
Stenosis, which means narrowing, can cause pressure on your spinal cord or the nerves that go from your spinal cord to your muscles.
More than 90% of the time, renal artery stenosis is caused by atherosclerosis, a process in which plaque made up of fats, cholesterol, and other materials builds up on the walls of the blood vessels, including those leading to the kidneys.
The prevalence of renal artery stenosis is probably less than 1% of patients with mild hypertension but can increase to as high as 10 % to 40% in patients with acute (even if superimposed on a preexisting elevation in blood pressure), severe, or refractory hypertension.
RAS can develop in both men and women. It's more common in older adults. According to the Mayo Clinic, you may also be at risk if you develop hypertension before the age of 30. Other risk factors for renal artery stenosis are similar to those of other forms of atherosclerosis.
Like other peripheral artery diseases, renal artery disease is caused by the buildup of plaque in the arteries that lead to the kidneys.
Your kidneys sit in the back of your abdomen (belly), just above your waist. Each renal artery is about 1½ to 2 inches (4 to 6 centimeters) long. The renal arteries start at the abdominal aorta. This branch of the aorta, your heart's main blood vessel, feeds vessels in your abdomen.
Buildup on kidney (renal) arteries. Fats, cholesterol and other substances (plaque) can build up in and on your kidney artery walls (atherosclerosis). As these deposits get larger, they can harden, reduce blood flow, cause kidney scarring and eventually narrow the artery.

A final reason to pursue revascularisation is the fact that patients with atheromatous renal artery stenosis have a worse prognosis than any other group on dialysis, with a median survival of 27 months, and prevention of progression to end stage renal failure may have greatest benefits in this group.
These are called ACE inhibitors and have names ending in -opril. Examples are captopril (also called 'Captopen'), lisinopril (also called 'Zestril'), ramipril, fosinopril. These are to be avoided because they can cause kidney failure in renal artery stenosis.
The prevalence rate of renal artery stenosis was 27% of 256 cases identified as having history of hypertension, while 56% showed significant stenosis (>50% luminal narrowing).
I70.1 is a billable diagnosis code used to specify a medical diagnosis of atherosclerosis of renal artery. The code I70.1 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.#N#The ICD-10-CM code I70.1 might also be used to specify conditions or terms like acquired renal artery stenosis, arteriosclerosis of renal artery, atherosclerosis of bilateral renal arteries, atherosclerosis of left renal artery, atherosclerosis of renal artery , atherosclerosis of right renal artery, etc.#N#The code I70.1 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
Atherosclerosis. Also called: Arteriosclerosis. Atherosclerosis is a disease in which plaque builds up inside your arteries. Plaque is a sticky substance made up of fat, cholesterol, calcium, and other substances found in the blood.
Many people don't know they have it until they have a medical emergency. A physical exam, imaging, and other diagnostic tests can tell if you have it. Medicines can slow the progress of plaque buildup.
An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I70.1:
