Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Ischemic Event

    The patients will be monitored whether they recured ischemic event including transient ischemic attack (TIA) or stroke confirmed by neurologist and diffusion-weighted image MRI.

    Up to 1 year

Secondary Outcomes (1)

  • Hyperperfusion Syndrome

    3 months

Study Arms (1)

carotid artery stenting and carotid endarterectomy

Symptomatic patients with unilateral ICA severe stenosis by magnetic resonance angiography were performed 3D pseudo-Continuous Arterial Spin Labeling MRI before and after CAS and CEA.

Other: MRI

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Symtomatic patients with unilateral severe internal carotid artery (ICA) stenosis.

You may qualify if:

  • informed patient's consent for ICA stenting or endarterectomy
  • lack of contraindications to MRI
  • Symptomatic, unilateral ICA stenosis 70-99%;irrelevant stenosis \<50% of contralateral ICA
  • TIA or stroke - within 360 days

You may not qualify if:

  • Intracranial hemorrhage
  • Informed consent not obtained
  • Patients with poor imaging quality(Poor imaging quality mainly defined as the image cannot be applied to future analysis on account of severe motion artifacts appeared in conventional MRI and mistakes in the MRI process by accident factors which cannot to be applied to future analysis)
  • Bilateral internal carotid artery occlusion
