Contact aspiration and stent retriever versus stent retriever alone following mechanical thrombectomy for patients of acute ischemic stroke: A recanalization success analysis

•A stent-assisted thrombectomy can use in symptomatic intracranial hemorrhage.•Contact aspiration plus stent retriever catheters have high chances of reperfusion.•Contact aspiration + stent retriever has fewer disease-related adverse effects.•The reperfusion parameter should be used to evaluate mechanical thrombectomy.•Failure attempts increased procedural time and procedural-adverse effects.
