Immediate flow restoration of the M1 segment after the deployment of Solitaire 6/30 mm (A). Because of the extension of the thrombus in the A1 segment, an additional Solitaire 4/20 mm was placed (B).

Same patient as in Figure 1. Same patient as in Figure 1. The dedicated MRI technique reveals no evidence of vessel wall injury: 2 successive sections are depicted covering the terminal internal carotid artery, the M1 and A1 segment on the right side, which were targeted by the mechanical thrombectomy. The MRI sequences include thin noncontrast T1 black-blood double inversion recovery (A), T2 black-blood double inversion recovery (B), and fat-suppressed T1-weighted images (C). Kety Hsieh et al.
