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.
Introduction: Both collateral flow via the internal carotid artery (ICA) terminus (ICT) and initial mild symptoms might be associated with favorable outcomes in patients with acute ICA occlusion (ICAO). 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 1,214 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 (NIHSS) score ≤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 hospital 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 < 0.001) and rates of diabetes mellitus (61.5% vs. 13.6%, p = 0.007), intravenous thrombolysis (IVT) (30.9% vs. 0%, p = 0.014), and mechanical thrombectomy (MT) (23.1% vs. 0%, p = 0.044) were significantly higher in patients with REND rather than in those without. The rate of patent ICT and MCA was comparable between groups. Except for 1 patient who underwent MT promptly after IVT immediately after REND, 3 patients initially treated with IVT deteriorated after the procedure. One patient without patent ICT and MCA did not meet the indications for MT. In 2 other patients with patent ICT and MCA, MT was not initially performed, but was eventually performed because of REND due to thrombus migration, and both were discharged with an mRS score of 5.
Conclusion: The overall clinical outcomes of patients with acute ICAO with mild symptoms were not depending on the patency of the ICT and MCA, but initial treatment with IVT alone might risk unfavorable outcomes due to thrombus migration in patients with patent ICT and MCA.
期刊介绍：
This open access and online-only journal publishes original articles covering the entire spectrum of stroke and cerebrovascular research, drawing from a variety of specialties such as neurology, internal medicine, surgery, radiology, epidemiology, cardiology, hematology, psychology and rehabilitation. Offering an international forum, it meets the growing need for sophisticated, up-to-date scientific information on clinical data, diagnostic testing, and therapeutic issues. The journal publishes original contributions, reviews of selected topics as well as clinical investigative studies. All aspects related to clinical advances are considered, while purely experimental work appears only if directly relevant to clinical issues. Cerebrovascular Diseases Extra provides additional contents based on reviewed and accepted submissions to the main journal Cerebrovascular Diseases.
