Clinical and TCD data of patients with TIA/stroke after stenting
| Patient No. Age in Years | Clinical Symptoms and Time Onset | Grade of Ipsilateral and Contralateral Stenosis and Plaque Characteristics | MFV, PI of Ipsilateral MCA before, Early after CAS, and 30 Days Later | Basal Ipsilateral CVR and 30 Days after CAS |
