Assessment of stent retrievers in acute ischaemic stroke

摘要

There has been healthy scepticism about the use of mechanical clot retrieval devices in the treatment of acute ischaemic stroke. Such devices give higher rates of recanalisation than does counterpart treatment with intravenous recombinant tissue plasminogen activator (rt-PA), but might not be associated with improvements in outcome for patients. Analysis of the National Inpatient Sample of almost 4000 patients who received endovascular clot retrieval therapy for acute ischaemic stroke showed that about 75% had either died in hospital or were discharged to long-term care facilities.2 A data synthesis of neurothrombectomy studies in acute ischaemic stroke concluded that although the devices provide intriguing treatment options,
