Stenotic lesions

Are the culprit lesions severely stenotic?

Cellular phenotypes in human stenotic lesions from haemodialysis vascular access.

BACKGROUND Haemodialysis vascular access dysfunction (due to venous stenosis and thrombosis) is a leading cause of hospitalization and morbidity. The aim of the current study was to identify the specific cell types present within stenotic tissue samples from patients with AV fistula and graft failure. METHODS Discarded tissue segments were collected from the stenotic portions (usually near th...

Stenotic occlusive lesions of internal carotid artery in diabetic patients.

Diabetes deteriorates atherosclerotic changes in the arteries. The aim of the study was to assess the prevalence and localization of stenotic atherosclerotic lesions of the internal carotid artery (ICA) in patients with diabetes. A prospective analysis of angiography findings was carried out in 150 diabetic and 150 non-diabetic patients with symptoms of cerebral ischemia using double-blind angi...

Physical factors in the progression of stenotic vascular lesions.

An explanation of the progression of stenotic lesions was sought in animal experiments. After surgical decrease of the lumen of arteries, progressive ingrowth of fibrous connective tissue led to the development of stenosis with changes in the artery that resembled those of coaretation. These changes are explained by the action of local blood pressures. Phenomena such as progressive stenosis, va...

Effect of variation in coronary artery anatomy on distribution of stenotic lesions.

A relation between the proximal or distal localisation ofatherosclerotic lesions and 3 anatomical variables (i) the length of the left main coronary artery, (ii) its angle of bifurcation into anterior descending and circumflex arteries, and (iii) the dominant coronary artery, was sought at coronary angiography. Studies were made on 149 angiograms of which 95 had critical stenoses (>50% of vesse...
