| carotid stenosis | The narrowing or stricture of a carotid artery that may lead to transient ischemic attacks (see cerebral ischemia, transient) and stroke (see cerebrovascular disorders). (12 Dec 1998) |
|---|---|
| renal artery stenosis | <cardiology, nephrology> A narrowing of the renal artery or one of its main branches accounts for 2 to 5% of cases of hypertension. (27 Sep 1997) |
| congenital pyloric stenosis | <radiology> Not seen until 3 weeks, projectile vomiting, palpable olive in RUQ/epigastrium (12 Dec 1998) |
| muscular subaortic stenosis | <cardiology> A congenital heart disease that results in abnormal thickening of the ventricular septum and left ventricular wall. Enlargement of the ventricular septum can result in ventricular outflow obstruction (subaortic stenosis) and eventual cardiomyopathy. (27 Sep 1997) |
| coronary ostial stenosis | Narrowing of the mouths of the coronary arteries as a result of syphilitic aortitis or atherosclerosis. (05 Mar 2000) |
| pulmonary stenosis | <cardiology> A congenital or acquired heart valve defect. The abnormal narrowing and ineffective opening of the pulmonic valve. Symptoms include cyanosis and difficulty breathing. Treatment is surgical in most cases of significant valvular stenosis. (27 Sep 1997) |
| pulmonary subvalvular stenosis | Stenosis of the conus arteriosus (infundibulum) with or without involvement of the pulmonary valve. It is usually associated with a defect in the interventricular septum. (12 Dec 1998) |
| pyloric stenosis | <gastroenterology, paediatrics> A congenital disorder in which the pylorus is thickened causing obstruction of the gastric outlet (to the duodenum). More common in males. Symptoms of projectile vomiting begin several weeks after birth. Incidence: approximately 1 in 4,000 live births. (27 Sep 1997) |
| hypertrophic pyloric stenosis | <radiology> Not seen until 3 weeks, projectile vomiting, palpable olive in RUQ/epigastrium (12 Dec 1998) |
| spinal stenosis | An abnormal narrowing of the spinal canal that may be either congenital or acquired. Treatment is generally surgical to widen the spinal canal. Laminectomy may be the indicated surgical procedure to reduce pressure on the spinal cord. (27 Sep 1997) |
| stenosis | Narrowing or stricture of a duct or canal. Origin: Gr. Stenosis (18 Nov 1997) |
| subaortic stenosis | <cardiology> The congenital narrowing of the outflow tract of the left ventricle due to a ring of fibrous tissue or enlargement of the ventricular septum. (27 Sep 1997) |
| subvalvar stenosis | <cardiology> The congenital narrowing of the outflow tract of the left ventricle due to a ring of fibrous tissue or enlargement of the ventricular septum. (27 Sep 1997) |
| subvalvular aortic stenosis | <radiology> Types: anatomic/fixed subaortic stenosis: associated with cardiac defects in 50% (usually VSD), functional/dynamic subartic stenosis: asymetrical septal hypertrophy (ASH), idiopathic hypertrophic subaortic stenosis (IHSS), hypertrophic obstructive cardiomyopathy (HOCM) findings: asymmetrically thicker ventricular septum than free wall of the left ventricle (95%), normal/small left and right ventricular cavities (95%), systolic anterior motion of the mitral valve, lucent subaortic filling defect in systole, coarse systolic flutter of valve cusps, may see mitral regurgitation (secondary to abnormal position of anterolateral pappilary muscle) see: aortic stenosis (12 Dec 1998) |
| supravalvar aortic stenosis-infantile hypercalcaemia syndrome | <syndrome> Supravalvar aortic stenosis associated with elfin facies, mental retardation, and hypercalcaemia; usually sporadic; perhaps an irregular dominant trait. (05 Mar 2000) |
