Novel intra‐arterial strategies in the treatment of acute ischaemic stroke

Acute ischaemic stroke is among the leading causes of death and disability in developed societies. I.v. and intra‐arterial thrombolysis, and mechanical thrombectomy carried out within the appropriate time window can result in superior clinical outcomes compared with traditional therapy consisting of anticoagulation and/or aspirin. In cases where thrombolysis and/or thrombectomy have not been proven effective or have failed to result in rapid clinical and/or angiographic improvement, novel intra‐arterial strategies may be applied by experienced interventional neuroradiologists to achieve recanalization of recalcitrant vessel occlusions with good clinical outcomes.
