Abstract

OBJECTIVES The aim of this study was to identify the optimal endovascular approach in patients with acute stroke with tandem lesions. BACKGROUND At present, there is no consensus about the ideal technical strategy for the endovascular treatment of patients with acute ischemic stroke with tandem lesions of the extracranial internal carotid artery (ICA) and intracranial cerebral arteries. METHODS This was an international, multicenter registry with a total of 482 patients with acute ischemic stroke and tandem lesions. Patients were treated by intracranial thrombectomy as well as 1 of the following 4 strategies: 1) acute carotid artery stenting of the extracranial ICA with antithrombotic agents;2) acute carotid artery stenting of the extracranial ICA without antithrombotic agents;3) balloon angioplasty of the extracranial ICA;and 4) intracranial thrombectomy alone. The main outcome endpoints of the study were the degree of recanalization and the 90-day clinical outcome. The safety endpoints were symptomatic intracerebral hemorrhage and all causes of mortality at 90 days. RESULTS Using univariate analysis, the rates of successful reperfusion (modified Thrombolysis in Cerebral Infarction grades 2B and 3) and favorable clinical outcome after 90 days were significantly higher after acute carotid stenting with antithrombotic therapy and thrombectomy compared with the group with thrombectomy alone. After adjusting for confounding variables, acute stenting with antithrombotic therapy was independently associated with successful recanalization (odds ratio: 2.4;95% confidence interval: 1.25 to 4.59;p = 0.008). The rates of symptomatic intracerebral hemorrhage and 90-day mortality were comparable among all 4 treatment groups. CONCLUSIONS Acute stenting of the extracranial ICA with antithrombotic therapy in combination with intracranial thrombectomy is associated with higher recanalization rates in treatment of patients with acute stroke with tandem lesions.
