title: The internal elastic lamina in the basilar artery and its possible significance for intimal thickening. A morphometric study.
abstract: The degree of intimal thickening, folding of the internal elastic lamina (IEL) and luminal radius/wall thickness ratio (RWR) have been compared between predilectional sites and a non-predilectional site for atherosclerosis in human basilar arteries. The findings are compatible with the hypothesis that a low degree of folding and a high RWR facilitate intimal thickening. A negative correlation between the fold index and intimal thickening index and a positive correlation between RWR index and intimal thickening index were found. Predilectional areas also have lower fold indices and higher RWR in younger subjects prior to any intimal thickening development.
