In contrast, preoperative diffusion-weighted imaging\u2013Alberta Stroke Program early computed tomography scores were 9 (1\u201311) and 6.5 (0\u201311) for the carotid non-T occlusion and carotid T occlusion groups, respectively ( P\u2009=\u20090.015). The duration of treatment or the median number of passes (2.5 vs. 2.0), the numbers of patients with thrombolysis in cerebral infarction 2b\/3, bleeding complications and modified Rankin scale scores of 0\u20132 on postoperative day 90 did not significantly differ between the two groups. Manual aspiration before, internal carotid artery arrest while crossing a lesion and injection into the contralateral side were significantly more frequent in patients with carotid non-T occlusion. Intracranial internal carotid artery stenosis was significantly more frequent in patients with carotid non-T occlusion ( n\u2009=\u20094, 20%) than carotid T occlusion ( n\u2009=\u20090), and 10% of patients with carotid non-T occlusion had arterial dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patients with carotid non-T occlusion more frequently had a background of intracranial internal carotid artery stenosis or arterial dissection than patients with carotid T occlusion.
