165 MRI Vessel Wall Imaging after Intra-Arterial Treatment for Acute Ischemic Stroke 7 Table 2. Location of occlusion and treatment details, including detected enhancing vessel wall foci, in the IAT-group. Patient ID Occlusion site NIHSS NOP Time symptom onset – IAT (min) Procedural time (min) TICI score alteplase Time IAT – MRI (days) Ipsilateral enhancing foci Contralateral enhancing foci 1 M1 right 10 1 190 35 TICI 3 Yes 33 - - 2 M1-M2 right 11 1 208 34 TICI 3 Yes 67 - M1-E 3 distal carotid left 8 3 318 50 TICI 2B No 84 M1-C - 4 M2 left 5 5 170 83 TICI 2B Yes 49 ICA-E, M2-E ICA-E 5 M2 left 5 1 127 42 TICI 3 Yes 65 - - 6 (large) M3 right 3 1 135 60 TICI 0 Yes 67 ICA-C - 7 distal carotid left 12 2 201 60 TICI 2B Yes 80 ICA-C - 8 M2 left 4 3 275 70 TICI 2B No 59 ICA-C, M1-E ICA-E 9 M1-M2 left 15 1 150 35 TICI 3 Yes 22 M1-E - 10 M1 left 14 1 150 39 TICI 3 Yes 24 M1-E - 11 M1 right 12 1 145 29 TICI 3 Yes 25 ICA-E 2x, M1-E - 12 M1-M2 right 20 1 76 40 TICI 3 Yes 51 - - 13 M1 right 15 0 44 42 TICI 3 Yes 57 - - 14 M1-M2 left 14 2 180 50 TICI 2B Yes 87 M1-C, M2-C - Table 2 . Treatment details of the 14 patients including the number and location of the detected foci of contrast enhancement (by AK). In patient 3, the enhancing focus detected in the M1-segment was distally located from the occlusion, but directly adjacent to the occlusion site and therefore identified as the same location as the thrombosuction site. C: concentric. E: eccentric. IAT: intra-arterial treatment. ICA: (distal intracranial) internal carotid artery. M: segment of the middle cerebral artery (M1 and M2). NIHSS: National Institutes of Health Stroke Scale. NOP: number of passes. Alteplase: recombinant tissue-type plasminogen activator. TICI: Thrombolysis in Cerebral Infarctions. 19
