Back­ground. The per­centage of sten­osis has ­been con­sid­ered for the ­last 20 ­years, and ­still con­tinues to be, the ­main cri­terion of ­choice ­between a sur­gical and a med­ical treat­ment of the ath­e­ros­cle­rotic ­lesions of the ­aortic arch branches, par­tic­u­larly as ­regards the internal carotid artery. On the ­other ­side, it has ­been dem­on­strated ­that the ­risk of ­adverse ­acute cereb­ro­vas­cular ­events, ­besides ­being ­related to the char­ac­ter­is­tics of the ­plaque, such as soft­ness, sub­in­timal hae­mor­rhage or sur­face ­ulcer, is ­strictly ­related to the ­actual ­residual ­lumen of the ­internal carotid artery. The pre-emi­nent ­role of the per­centage of sten­osis in the ­choice of the treat­ment, ­hence, pre­sumes a ­narrow ­range of vari­a­tion of the orig­inal cal­ibre of the ­vessel, yet to be ­proven.
­Methods. ­Five-hun­dred ­normal ­adults under­went the meas­ure­ment of the ­internal cal­ibre of the aortic arch branches by duplex ultra­sound in ­order to ­find out their ­actual ­range of vari­a­tion.
­Results. The ­range of vari­a­tion of the ­internal cal­ibre of the aortic arch branches, ­expressed as the ­ratio ­between the max­imum and the min­imum ­value ­found for ­each ­vessel, was ­very ­wide in all ­cases (­from 180% for the right ­common carotid artery to 340% for the right ver­te­bral artery). With reference to the internal carotid arteries, the ­range of vari­a­tion was 219% for the ­right internal carotid artery and 241% for the left internal carotid arteries.
Con­clu­sions. Due to the ­wide ­range of vari­a­tion of the orig­inal cal­ibre of the aortic arch branches, the per­centage of sten­osis ­alone ­cannot be con­sid­ered an accu­rate ­measure of the ­severity of the sten­osis, and ­hence a reli­able cri­terion of ­choice of the treat­ment.
