This complaint is from a literature source.As reported in the literature publication entitled ¿multicentric experience in distal-to-proximal revascularization of tandem occlusion stroke related to internal carotid artery dissection.¿ 1 patient with anterior circulation ischemic stroke treated with an endovascular approach who underwent the revascularization procedure and a cervical carotid stent placement experienced symptomatic intracranial hemorrhage in the basal ganglia occurred early despite a tici 3 recanalization.Nevertheless, the patient had a favorable outcome with an mrs of 2 after 3 months.1 patient with anterior circulation ischemic stroke treated with an endovascular approach who underwent the revascularization procedure and cervical carotid stent placement died for 3 months.The purpose of this study was to evaluate our endovascular ¿distal-to-proximal¿ strategy in the treatment of this stroke subtype in the first large multicentric cohort methods: prospectively managed stroke data bases from 2 separate centers were retrospectively studied between 2009 and 2014 for records of tandem occlusions related to internal carotid dissection.Atheromatous tandem occlusions were excluded.The first step in the revascularization procedure was intracranial thrombectomy.Then, cervical carotid stent placement was performed depending on the functionality of the circle of willis and the persistence of residual cervical ica occlusion, severe stenosis, or thrombus apposition.Cerenovus devices (stent enterprise) were used in this study.No devices specific information (including catalog and the lot number) were provided in the article.
