Research progress of time window and tissue window on mechanical thrombectomyin to acute ischemic stroke / 中国综合临床

ABSTRACT

Objective:Acute ischemic stroke (AIS) has a high incidence rate, high disability rate, high mortality and high medical expenses, which seriously affect the healthy living standard of our residents.Intravenous thrombolysis and mechanical thrombectomy within the time window are important methods for the treatment of AIS.The time window of mechanical embolectomy was extended from the initial 6 hours to 24 hours.The expansion of the time window enabled more patients to accept mechanical thrombectomy.However, some patients with more than 24 h time window have also achieved good results after strict multimodal evaluation.Therefore, there are some limitations in using time window to evaluate the indications of mechanical thrombectomy.In recent years, the way that time window combining with tissue window to evaluate the appropriate population of mechanical thrombectomy has become more and more popular.
