Reevaluating the Role of Heparin During Mechanical Thrombectomy for Acute Ischemic Stroke: Increased Risks Without Functional Benefit

Heparin may be administered during mechanical thrombectomy (MT) for acute ischemic stroke due to large vessel occlusions (AIS-LVO), with the aim of enhancing reperfusion and improving patient outcomes. The uncertain balance between risks and benefits of administering heparin during MT prompted us to perform this systematic review and meta-analysis.
