Note:—C indicates concentric; E, eccentric; M, segment of the middle cerebral artery (M1 and M2); NOP, number of passes; –, no enhancing foci detected.
↵a Treatment details of the 14 patients including the number and location of the detected foci of contrast enhancement (by A.G.v.d.K.). In patient 3, the enhancing focus detected in the M1 segment was located distal to the occlusion but directly adjacent to the occlusion site and therefore identified as the same location as the thrombosuction site.
