210 of CCA and/or ECA dissection. Thus, we estimate the prevalence of this type of dissection to be less than 1% of all cervical artery dissections. The reasons for the low frequency might be a different ultrastructure of the vessel wall in the CCA and ECA, but underdiagnosis due to a lack of attention regarding dissection of the ECA is also possible because dissection occurs without severe consequences/sequelae for the patients.
