Glossary for Renal Artery Stenosis

  • Abdominal conditions: Medical conditions affecting the abdominal region.
  • Aortic coarctation: A rare inherited birth defect where the heart blood vessel called the aorta has a narrowed area which affects blood flow. The degree of constriction is variable which mild cases asymptomatic until adulthood. The poor blood flow to the lower body gives results in it appearing less developed than that upper body.
  • Atherosclerosis: Atherosclerosis is a syndrome affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part due to the accumulation of macrophage white blood cells and promoted by low density (especially small particle) lipoproteins (plasma proteins that carry cholesterol and triglycerides) without adequate removal of fats and cholesterol from the macrophages by functional high density lipoproteins (HDL). It is commonly referred to as a hardening or furring of the arteries. It is caused by the formation of multiple plaques within the arteries.
  • Cardiovascular Disease: Diseases of the heart or blood vessels including cerebrovascular diseases such as stroke.
  • Chronic kidney failure: Gradual failure of the kidneys over a period of time
  • Circulatory system conditions: Medical conditions affecting the heart and the circulatory system.
  • Cushing's syndrome: A rare syndrome where excessive secretion of corticosteroids by the adrenal cortex leads to a variety of symptoms. Hormone-secreting adrenal or pituitary tumors are often the cause of the excessive corticosteroid secretion.
  • Decreased urine output: Decreased urine output is defined as producing less than 500 milliliters of urine in 24 hours.
  • Diabetes: Failing or reduced ability of the body to handle sugars.
  • Fibromuscular dysplasia of arteries: A rare disease where the blood vessel walls thicken and harden which reduces blood flow through the arteries and into various organs. The main arteries that may be affected are those in the kidney's and abdomen as well as the carotid artery which caries blood from the heart to the neck.
  • High blood pressure: High blood pressure
  • Hyperlipoproteinemia: Hyperlipoproteinemia is a medical term for high levels of lipids in the blood which in turn causes high cholesterol levels. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.
  • Hypertension: High blood pressure
  • Kidney conditions: Any condition affecting the kidney organs.
  • Neurofibromatosis: Nerve disorders often leading to tumors on nerves.
  • Neurofibromatosis Type 1 (NF-1): Neurofibromatosis Type 1 is a genetic disorder often leading to the development of nerve tumors. The condition is also characterized by skin pigmentation abnormalities.
  • Primary Hyperaldosteronism: A condition characterised by the excessive production and release into the circulation of aldosterone
  • Proteinuria: Protein in the urine
  • Smoking: The smoking of cigarettes
  • Williams Syndrome: A syndrome characterised by mental retardation, facial abnormalities and emotional instability
