A stenosis (/stəˈnsɨs/;[1][2] plural: stenoses, /stəˈnˌsz/) (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).[3] The term coarctation is a synonym,[4] but is commonly used only in the context of aortic coarctation.

Restenosis is the recurrence of stenosis after a procedure.

Diagnosis[edit]

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.

Causes[edit]

Types[edit]

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:
