- Abstract
- Objective: Strokes related to tandem occlusions of the internal carotid artery (ICA) and a major intracranial artery are associated with poor clinical outcome. We evaluated the clinical efficacy of endovascular approach for the management of these lesions. We also compared the clinical outcomes regarding the type of cervical ICA lesions; complete occlusion vs severe stenosis. Methods: We retrospectively reviewed 42 patients with acute ischemic stroke who underwent endovascular treatment for tandem lesions between January 2011 and April 2017. After dividing the patients into two groups according to lesion type of the proximal cervical ICA (complete occlusion and severe stenosis), we analyzed demographic data, angiographic findings and clinical outcomes. A modified Rankin Scale score <= 2 was defined as a favorable clinical outcome. Results: Of 42 patients, 27 patients (64.3%) had complete occlusion of the cervical ICA, and the remaining 15 had high-grade stenosis. Successful stenting was performed in all patients with favorable clinical outcomes (27/42, 64.3%). Successful reperfusion score (thrombolysis in cerebral infarction >= 2b) was 78.6%; occlusion group (18/27, 66.7%) vs stenosis group (15/15, 100%) of cases. Mean modified Rankin Scale score at 90 days was 2.36 +/- 1.83. The rate of favorable clinical outcome was higher in stenosis group (11/15, 73.3%) than that of occlusion group (16/27, 59.3%) with no statistically significant difference (p = 0.506). Conclusion: Acute endovascular treatment of carotid artery tandem lesions is a technically feasible and clinically effective intervention regardless of the lesion type in proximal cervical ICA. Advances in knowledge: Our study supports the results of previous studies in which endovascular therapy has a favorable clinical outcome in carotid artery tandem occlusion.
