Abstract
Objective To assess the changes of cerebral hemodynamics in patients with moderate and severe carotid artery stenosis by transcranial Doppler (TCD).Methods A total of 69 patients with internal carotid artery stenosis were divided into moderate group and severe group by digital subtraction angiography (DSA).TCD was used to detect the hemodynamic parameters of media cerebral artery and evaluate the establishment of collateral circulation and cerebral blood flow reserve capacity (CRV).Results TCD showed that the ipsilateral peak systolic flow velocity (Vs),pulsatility index (PI) and CVR in the patients with collateral circulation established were significantly higher than those of the patients without collateral circulation (P<0.05),the ipsilateral Vs,PI and CVR in internal carotid artery moderate stenosis group were significantly higher than those in severe group (P<0.05).Conclusion The establishment of collateral circulation can improve the distal hemodynamics in patients with the stenosis of internal carotid artery to some extent.TCD can detect intracranial hemodynamic changes in patients with internal carotid artery stenosis,and evaluate the collateral circulation,which can provide a reliable basis for clinical treatment and evaluation.关键词
