Restenosis

Restenosis is the recurrence of stenosis after a procedure.
Restenosis is the recurrence of stenosis, a narrowing of a blood vessel, leading to restricted blood flow.

Atherosclerosis

atheroscleroticatherogenesisatherosclerotic plaques
Stricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis).
Marked narrowing in the coronary arteries, which are responsible for bringing oxygenated blood to the heart, can produce symptoms such as the chest pain of angina and shortness of breath, sweating, nausea, dizziness or light-headedness, breathlessness or palpitations.

Birth defect

Congenital anomalies of the gastrointestinal system include numerous forms of stenosis and atresia, and perforation, such as gastroschisis.

Renal artery stenosis

Renal artery stenosis
Renal artery stenosis is the narrowing of one of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.

Coronary artery disease

Angina (coronary artery stenosis)
Chest pain that occurs regularly with activity, after eating, or at other predictable times is termed stable angina and is associated with narrowings of the arteries of the heart.

Aortic stenosis

Aortic valve stenosis, which is the thickening of the aortic valve, therefore causing narrowing
Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result.

Pyloric stenosis

Pyloric stenosis (gastric outflow obstruction)
Pyloric stenosis is a narrowing of the opening from the stomach to the first part of the small intestine (the pylorus).

Spinal stenosis

Lumbar, cervical or thoracic spinal stenosis
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots.

Heart valve

The other form of valvular heart disease is stenosis, a narrowing of the valve.

Tricuspid valve stenosis

Tricuspid valve stenosis, which is the thickening of the tricuspid valve (of the right heart), therefore causing narrowing
It is a relatively rare condition that causes stenosis-increased restriction of blood flow through the valve.

Transient ischemic attack

Carotid artery stenosis which predispose to (strokes and transient ischaemic episodes)
There are three major mechanisms of ischemia in the brain: embolism traveling to the brain, in situ thrombotic occlusion in the intracranial vessels supplying the parenchyma of the brain, and stenosis of vessels leading to poor perfusion secondary to flow-limiting diameter.

Angina

Angina (coronary artery stenosis)
1) a reduction of blood flow to the heart that can be caused by stenosis, spasm, or acute occlusion (by an embolus) of the heart's arteries.

Smoking

Among the diseases that can be caused by smoking are vascular stenosis, lung cancer, heart attacks and chronic obstructive pulmonary disease.

Heart

Tricuspid valve stenosis, which is the thickening of the tricuspid valve (of the right heart), therefore causing narrowing Mitral valve stenosis, which is the thickening of the mitral valve (of the left heart), therefore causing narrowing
It can be influenced by narrowing of the heart valves (stenosis) or contraction or relaxation of the peripheral blood vessels.

Stenosing tenosynovitis

Stenosing tenosynovitis
Repetitive forceful compression, tensile stress, and resistive flexion, causes inflammation, swelling, and microtrauma, that results in thickening (commonly a nodular formation) of the tendon distal to the pulley and stenosis of the tendon sheath leading to a painful digital base, limitation of finger movements, triggering, snapping, locking, and deformity progressively.

Tracheobronchial injury

bronchial tearlarynx, trachea or bronchitracheal fracture
Early diagnosis is important to prevent complications, which include stenosis (narrowing) of the airway, respiratory tract infection, and damage to the lung tissue.

Subglottic stenosis

Subglottic stenosis (SGS)
Subglottic stenosis can present as a life-threatening airway emergency.

Hydrocephalus

Non-communicating hydrocephalus
Obstruction to CSF flow hinders its free passage through the ventricular system and subarachnoid space (e.g., stenosis of the cerebral aqueduct or obstruction of the interventricular foramina) secondary to tumors, hemorrhages, infections or congenital malformations) and can cause increases in central nervous system pressure.
