Article Figures & Data

Figures

  • Fig 1.
    Fig 1.

    DWI (b = 1000) of the brain before (A) and 1 day after (B) stent placement of the right carotid artery. A small new cortical lesion within the ipsilateral hemisphere is visible (arrow).

  • Fig 2.

    Proportion of patients with (new DWI lesions) and without (no new DWI lesions) new ischemic lesions in DWI 1 day after CAS with (solid MES) and without (no solid MES) ipsilateral solid MESs during the procedure

    • Note:—Data are on solid microembolic signal (MES) during carotid artery stenting (CAS) and on the frequency of new diffusion-weighted MR imaging (DWI) lesions 24 ± 2 hours after CAS.

    • * Grade of carotid stenosis according to the North American Symptomatic Carotid Endarterectomy Trial (NASCET) methods of measuring carotid stenosis.

  • Table 2:

    Solid MES during unprotected CAS

    CAS PhasesSolid MES during 27 CAS (n, Range)
    (1) Sheath and introducer catheter placement57 (0–15)
    (2) Guidewire crossing stenosis29 (0–6)
    (3) Stent delivery202 (0–72)
    (4) Balloon dilation130 (0–31)
    (5) Balloon deflation66 (0–15)
    Total484 (0–119)
    Friedman test (dF = 4/134)
        Chi-square15.07
        P (F).005

    • Note:—MES indicates microembolic signal; CAS, carotid artery stent placement.
