Short- and Long-Term Hemodynamic Effects of Carotid Endarterectomy and Carotid Artery Stenting

Carotid artery stenting(CAS) and endarterectomy(CEA) are both important treatment strategy for patients with ICA (internal carotid artery) stenosis. Three dimensional pseudo-continuous arterial spin labeling (pCASL) is a noninvasive perfusion imaging modality to detect reperfusion for recanalization therapy. And it provides information about absolute CBF (ml 100 g-1 tissue min-1) at the brain tissue level. The aim of the present study was to evaluate the series hemodynamic changes in patients who had conducted CAS or CEA by using 3D pseudo-continuous arterial spin labeling (pCASL) to explore the potential pattern of CBF alternation and thus to improve the prevention strategy for hyperperfusion syndrome.
