nephroangiosclerosis
Học thuậtThân thiện
Definition
Noun: A medical condition involving kidney disease, typically linked to high blood pressure (hypertension). It is characterized by the hardening (sclerosis) of the small arteries (arterioles) within the kidneys. This narrowing reduces blood flow, which can ultimately lead to the impairment of kidney function (kidney failure) and can also contribute to heart failure.
Usage
This is a highly specialized medical term used primarily in clinical, pathological, and academic contexts to describe a specific vascular pathology of the kidneys. * The autopsy report listed nephroangiosclerosis as a contributing factor to the patient's renal failure. * Long-standing, uncontrolled hypertension is a major risk factor for the development of nephroangiosclerosis.
Advanced Usage
- The term is often used in differential diagnoses to distinguish this condition from other forms of kidney disease, such as glomerulonephritis or diabetic nephropathy.
- In pathological descriptions, it may be discussed in terms of its histological features, such as "hyaline arteriolosclerosis."
Variants and Related Words
- Nephrosclerosis: A broader, more general term for the hardening of kidney tissue, of which nephroangiosclerosis is a specific type (focused on the blood vessels).
- Hypertensive Nephropathy: A clinical term often used synonymously to describe kidney damage caused by high blood pressure, with nephroangiosclerosis being a key pathological mechanism.
Synonyms
- Hypertensive nephrosclerosis
- Arteriolar nephrosclerosis
Related Phrases / Concepts
- Benign nephrosclerosis: A common form associated with long-term hypertension.
- Malignant nephrosclerosis: A severe, accelerated form associated with very high blood pressure (malignant hypertension).
Noun
- kidney disease that is usually associated with hypertension; sclerosis of the renal arterioles reduces blood flow that can lead to kidney failure and heart failure
