We have read the article by Hwang et al1 about the impact of residual stenosis on outcome after endovascular revascularization in patients with acute anterior circulation stroke and middle cerebral artery (MCA) occlusion. In their study, 21 patients had instant reocclusion (IR) during endovascular procedure and 9 patients had delayed reocclusion (DR) on follow-up angiographic imaging acquired 5 to 7 days after endovascular therapy. In situ thrombosis (IST) secondary to atherosclerotic lesion was determined to be the hidden pathogenesis of MCA occlusion in 8 of 9 patients with DR and 16 of 21 patients with IR.1In 8 patients with IST and DR, excellent pretreatment collateral flow was demonstrated to be associated with DR.1 Considering the multiple beneficial effects of good …
