A stenosis (plural: stenoses; from Ancient Greek στένωσις, "narrowing") is an abnormal narrowing in a blood vessel or other tubular organ or structure.
It is also sometimes called a "stricture" (as in urethral stricture).
The term "coarctation" is synonymous,[1] but is commonly used only in the context of aortic coarctation.

Diagnosis
Stenoses of the vascular type are often associated with unusual blood sounds resulting from turbulent flow over the narrowed blood vessel. This bruit can be made audible by a stethoscope but diagnosis is generally made or confirmed with some form of medical imaging.

Types
The resulting syndrome depends on the structure affected.
Examples of vascular stenotic lesions include:
- Intermittent claudication (peripheral artery stenosis)
- Angina (coronary artery stenosis)
- Carotid artery stenosis which predispose to (strokes and transient ischaemic episodes)
- Renal artery stenosis
Stenoses/strictures of other bodily structures/organs include:
- Pyloric stenosis (gastric outflow obstruction)
- Obstructive jaundice (biliary tract stenosis)
- Bowel obstruction
