Morphometric evaluation of the delayed cerebral arteries response to acetazolamide test in patients with chronic carotid artery stenosis using computed tomography angiography

Abstrakt

Background: The evidence accumulates that the response to acetazolamide test is delayed on the ipsilateral side to stenosis. However, the effect of acetazolamide beyond 30 minutes after acetazolamide administration remains unknown. The aim of this study was to assess the diameters of: anterior cerebral arteries (ACAs), middle cerebral arteries (MCAs) and posterior cerebral arteries (PCAs) before and 60 minutes after the acetazolamide test. Materials and Methods: Seventeen patients with carotid artery stenosis ≥90% on the ipsilateral side and, ≤50% on the contralateral side were enrolled into the study. Diagnosis was based on ultrasonography examination and was confirmed using digital subtractive angiography. In all patients, two computed tomography angiography examinations were carried out; the first was performed before the acetazolamide administration while the second one was carried out 60 minutes after injections. Results: In response to the acetazolamide test: PCA diameter diminished in both ipsi- and contra- lateral side to stenosis (from 1.31 to 1.24 mm and from 1.23 to 1.15, respectively), ACA and MCA decreased in the contralateral side to the stenosis (from 1.33 to 1.26 and from 2.75 to 2.66 mm, respectively), ACA and MCA increased in the ipsilateral side to the stenosis (from 1.29 to 1.46 mm and from 2.77 to 2.96, respectively). All changes were statistically significant. Conclusions: There were significant differences in reactivity to acetazolamide challenge between the internal carotid artery (ICA) and vertebra-basilar circulation in patients suffering from chronic carotid artery stenosis. Within the ICA territory ACAs and MCAs responses vary in the affected and not affected side.
