Estimating basilar artery upper rupture limit by dangerous alarming diameter of arteries (DADA) following bilateral common carotid artery ligation; a new theorem

Abstract

An inverse relationship was discovered between the DADA/VDI values. BCCAL may lead to severe dangerous histopathological changes at the BA. Lower DADA or higher VDI values may lead to severe basilar enlargement, endothelial losing, inner elastic membrane rupture, and aneurysm formation after BCCAL.
