MeSH D003251

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).[1]

The term coarctation is synonymous,[2] but is commonly used only in the context of aortic coarctation.



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



The resulting syndrome depends on the structure affected.

Examples of vascular stenotic lesions include:

The types of stenoses in heart valves are:

Stenoses/strictures of other bodily structures/organs include:
