Stenosis

From WikiMD free medical encyclopedia
Jump to: navigation, search


A stenosis (Template:IPAc-en;[1][2] plural: stenoses, Template:IPAc-en) (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

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

Types
