Summary

The aim of this observational pilot study is to determine whether intolerance of carotid occlusion during carotid artery stenting can be predicted with preprocedural transcranial Doppler evaluation.

Detailed description

Carotid artery stenting procedures are increasingly performed with devices that involve endovascular clamping of the common carotid artery, thus exposing the ipsilateral hemisphere to hypoperfusion. Approximately 5% of patients do not tolerate the clamp and are in increased risk of periprocedural cerebrovascular complication such as transient ischemic attack or stroke. To date, there is no method available that could be used to predict the risk of occlusion intolerance. The aim of this study is to determine whether preprocedural evaluation with transcranial Doppler ultrasonography can be effective in prediction of occlusion intolerance.
