Endovascular thrombectomy and intra-arterial interventions for acute ischaemic stroke.

Cochrane Database Syst Rev 2021 Jun 14;6:CD007574. Epub 2021 Jun 14.

University Hospital of North Norway, Tromsø, Norway.

Background: Most disabling strokes are due to a blockage of a large artery in the brain by a blood clot. Prompt removal of the clot with intra-arterial thrombolytic drugs or mechanical devices, or both, can restore blood flow before major brain damage has occurred, leading to improved recovery. However, these so-called endovascular interventions can cause bleeding in the brain. Read More
