Vascular Stenosis Arterial stenosis •
Carotid artery stenosis •
Coronary artery stenosis •
Renal artery stenosis • Peripheral artery stenosis • Vertebral artery stenosis • Cerebral artery stenosis •
Pulmonary artery stenosis •
Congenital or acquired abnormal narrowing of
pulmonary arteries along any portion of the pulmonary artery tree Venous stenosis • Jugular venous stenosis • Central venous stenosis
Cardiac Valve Stenosis In order from most to least common: •
Aortic valve stenosis • Normal aortic
valves are estimated to be less than a millimeter thick. Subsequent
fibrosis and
calcification of the valve leads to narrowing of the valve and therefore decreased blood flow out of the heart. • Congenital subtypes • Tracheobronchial remnants • Fibromuscular thickening / fibromuscular stenosis • Membranous webbing or esophageal membrane • Acquired • Injury (example: swallowing button battery ) • Gastroesophageal reflux disease (GERD) • Eosinophilic esophagitis (EoE) •
Achalasia •
Pyloric stenosis (infantile hypertrophic pyloric stenosis) • Relatively uncommon disorder of infants, usually between the ages of 2–12 weeks, caused by abnormal thickening of the
pylorus muscle in the stomach at the junction between the end of the stomach and the beginning of the
duodenum. • Small-bowel stenosis • Colonic stenosis (bowel obstruction) •
Anal stricture •
Rectal stricture Respiratory Stenosis •
Subglottic stenosis •
Congenital or acquired narrowing of airway diameter in anatomic area below the
vocal cords. •
Laryngotracheal stenosis • Bronchial stenosis
Genitourinary Stenosis • Ureteral stenosis • Urethral stenosis • Cervical canal stenosis •
Meatal stenosis •
Vaginal stenosis • Abnormal shortening or tightening of the
vaginal canal.
Others • Biliary duct stenosis ==Causes==
