Impact of patency of the carotid terminus and middle cerebral artery on early clinical outcomes in patients with acute internal carotid artery occlusion and mild symptoms

This study aimed to address the association between early clinical outcomes and patency of the ICT and middle cerebral artery (MCA) in patients with acute ICAO with mild symptoms. Methods: Of 1214 consecutive patients with acute ischemic stroke or transient ischemic attack due to large vessel occlusion, patients with ipsilateral ICAO and initial National Institutes of Health Stroke Scale score (NIHSS) ≤ 5 were retrospectively enrolled. We examined the associations between clinical factors including patency of the ICT and MCA and recurrence of stroke or early neurological deterioration (REND). Significant early neurological deterioration was defined as increment in NIHSS score ≥ 1 during hospi tal stay. Results: Thirteen of the 35 patients who were finally enrolled had REND (37%), and median modified Rankin Scale (mRS) score at discharge was 1 (interquartile range, 0–4). Initial NIHSS score (4 vs. 1, p
