Overview
Renal Artery Stenosis
Renal artery stenosis is narrowing of one or both arteries that supply blood to the kidneys. Reduced blood flow can activate mechanisms that raise blood pressure and, in some cases, impair kidney function. The most common causes are atherosclerosis and fibromuscular dysplasia. Some people have no symptoms, while others develop difficult-to-control hypertension or declining kidney function.
Liver Cirrhosis
Liver cirrhosis is advanced scarring of the liver that develops after long-term or repeated liver injury. Scar tissue gradually replaces healthy liver tissue and can interfere with blood flow and the liver's ability to perform important functions. Causes include chronic viral hepatitis, long-term alcohol-related liver injury, metabolic liver disease, and other conditions that produce persistent liver damage. Early cirrhosis may cause few symptoms, while advanced disease can lead to fluid accumulation, jaundice, bleeding problems, confusion, or other serious complications. Managing the underlying cause can help slow further liver damage.

Renal Artery Stenosis
Diagnosis involves assessing blood pressure, kidney function, cardiovascular risk factors, and features suggesting renovascular disease. Imaging may include Doppler ultrasound, CT angiography, or magnetic resonance angiography to evaluate renal arteries. In selected circumstances, catheter-based angiography provides detailed visualization. Testing is generally considered when renal artery narrowing is clinically suspected, particularly with difficult-to-control hypertension or unexplained deterioration in kidney function.
Liver Cirrhosis
Diagnosis of cirrhosis may involve medical history, physical examination, blood tests, imaging, and sometimes specialized assessment of liver stiffness. Blood tests can evaluate liver function, blood-cell counts, clotting, and evidence of underlying causes. Ultrasound and other imaging methods can assess liver structure, blood flow, and complications. Elastography can estimate liver stiffness. In selected cases, additional testing or liver biopsy may be considered to clarify the diagnosis or underlying cause.
Prevention
Renal Artery Stenosis
Atherosclerotic renal artery stenosis shares many risk factors with cardiovascular disease. Not smoking, maintaining healthy blood pressure and cholesterol levels, controlling diabetes, exercising regularly, maintaining a healthy weight, and following a heart-healthy diet can reduce vascular risk. People with established cardiovascular disease should follow recommended medical treatment and monitoring. Fibromuscular dysplasia cannot generally be prevented through lifestyle measures.
Liver Cirrhosis
Preventing cirrhosis involves preventing or treating the conditions that cause long-term liver injury. Avoiding excessive alcohol, preventing hepatitis B infection through vaccination when appropriate, reducing exposure to hepatitis C, maintaining a healthy weight, and managing diabetes and metabolic conditions can reduce liver-related risk. People with chronic hepatitis, fatty liver disease, autoimmune liver disease, or other liver disorders should follow medical advice and undergo appropriate monitoring. Avoiding unnecessary medicines or supplements that may injure the liver can also be important.
Risk Factors
Renal Artery Stenosis
Risk factors for atherosclerotic renal artery stenosis include older age, smoking, high blood pressure, diabetes, high cholesterol, and other cardiovascular risk factors. Fibromuscular dysplasia is more often associated with women and may occur without the usual cardiovascular risk factors. A history of vascular disease elsewhere in the body can also increase the likelihood of renal artery narrowing.
Liver Cirrhosis
Risk factors for cirrhosis include long-term alcohol misuse, chronic hepatitis B or C infection, metabolic dysfunction-associated fatty liver disease, obesity, diabetes, and conditions that cause persistent liver inflammation or injury. Certain inherited disorders, autoimmune diseases, and chronic bile-duct disorders can also increase risk. The likelihood of progression depends on the underlying cause, duration and severity of liver injury, and whether the cause is identified and treated.
