Endovascular treatment of patients with acute ischemic stroke and tandem occlusion due to internal carotid artery dissection: A multicenter experience

Background The optimal management of patients with acute ischemic stroke (AIS) due to tandem occlusion (TO) and underlying carotid dissection (CD) remains unclear. Objective We present our multicenter-experience of endovascular treatment (EVT) approach used and outcomes for AIS patients with CD-related TO (CD-TO). Methods Consecutive AIS patients underwent EVT for CD-TO at five Italian Neuro-interventional Tertiary Stroke Centers were retrospectively identified. TO from atherosclerosis and other causes of, were excluded from the final analysis. Primary outcome was successful (mTICI 2b-3) and complete reperfusion (mTICI 3); secondary outcome was patients’ 3-months functional independence (mRS≤2). Results Among 214 AIS patients with TO, 45 presented CD-TO. Median age was 54 years (range 29–86), 82.2% were male. Age
