Conditions

Ischemic Stroke

Brief summary

Thrombolysis and endovascular thrombectomy are the most efficient treatments for acute ischemic stroke patients in time window. Although sufficient recanalization after thrombectomy is more than 80%, HERMES study indicated that nearly half of the ischemic stroke patients under thrombectomy suffered obvious disability. Artery reocclusion, hemorrhagic transformation, and no-reflow phenomenon are among the most important reasons of poor prognosis of acute ischemic stroke patients. The investigators speculate that a combination of argatroban, edaravone, and glucocorticoid may be helpful in preventing artery reocclusion, hemorrhagic transformation, and no-reflow phenomenon. This study intends to explore the safety, feasibility and efficacy of thrombectomy with sufficient recanalization bridged by intra-arterial cocktail therapy in acute ischemic stroke patients.

Interventions

DRUGintra-arterial cocktail therapy

Intra-arterial administration of argatroban (0.2-0.3 mg/min), dexamethasone (0.1 mg/min) and edaravone (0.3 mg/min) for 30 to 60 minutes after thrombectomy.
