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
- atherosclerosis causes stenotic lesions in arteries.
- birth defects
- diabetes
- iatrogenic, e.g. secondary to radiation therapy
- infection
- inflammation
- ischemia
- neoplasm - in such cases, the stenosis is often said to be "malignant" or "benign", although this attribute actually refers to the neoplasm itself.
- smoking
- ureteral
- urethral
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
The types of stenoses in heart valves are:
Stenoses/strictures of other bodily structures/organs include:
- Pyloric stenosis (gastric outflow obstruction)
- Lumbar, cervical or thoracic spinal stenosis
- Subglottic stenosis (SGS)
- Tracheal stenosis
- Obstructive jaundice (biliary tract stenosis)
- Bowel obstruction
- Phimosis
- Non-communicating hydrocephalus
- Stenosing tenosynovitis
