Abstract
The aim of our study was to assess the influence of carotid endarterectomy on cerebrovascular reactivity. The cerebrovascular reactivity was expressed as a percentage increase of middle cerebral artery blood flow velocity during breath holding, called the breath holding index (BHI). The middle cerebral artery blood flow velocity was measured using transcranial Doppler sonography. The measurements were carried out in 26 patients with unilateral high grade (>=70%) internal carotid artery stenosis before and after carotid endarterectomy. On the operated side before operation BHI was 21+7% and after operation 31.5+6% (p< 0.001); on the contralateral there were no significant changes. Conclusion: carotid endarterectomy improves cerebrovascular reactivity in patients with carotid artery disease on the operated side.
