BACKGROUND: The precise etiology of border zone @entity1188 is controversial. @entity73 due to @entity432 (ICA) is suggested as a cause of border zone @entity1188 . OBJECTIVE: To investigate changes in prevalence and volume of @entity63 border zone lesions over time in @entity1 with occlusive disease of the ICA after 1 year of follow-up. DESIGN: Follow-up study. SETTING: Referral center. @entity1 : Fifty-eight @entity1 with an occlusion of the ICA were included. At baseline, @entity2806 were classified on magnetic resonance imaging, and vasomotor reactivity was assessed with transcranial Doppler ultrasonography with @entity544 challenge. MAIN OUTCOME MEASURES: Changes in prevalence and volume of @entity2806 were monitored and were correlated with @entity544 reactivity at baseline. RESULTS: No significant changes in the prevalence of any @entity1188 types were observed after 1 year of follow-up in the hemispheres ipsilateral or contralateral to the @entity432 . However, in hemispheres ipsilateral to an occluded ICA, we found an increase in mean volume of internal border zone @entity1188 (P =.002). In hemispheres with a low @entity544 reactivity, we found an increase in mean volume of internal border zone lesions after 1 year ( @entity544 reactivity, <or=18%, P =.02 and 19%-35%, P =.02). These changes were not observed for external border zone lesions. CONCLUSION: The association between impaired vasomotor reactivity and an increase in @entity63 lesion volume in the internal border zone suggests a hemodynamic component.
