机械取栓装置在缺血性卒中患者治疗中的应用

Mechanical thrombectomy for acute ischemic stroke

目前，在发病4．5h内进行静脉溶栓仍然是治疗急性缺血性卒中患者的最有效方法。对于不符合静脉溶栓治疗标准、静脉溶栓后症状无明显改善甚至恶化的患者，血管内介入治疗是一种安全的替代治疗方法。经动脉机械取栓装置能实现迅速和完全的血管再通，为急性缺血性卒中患者提供了更多的治疗选择。文章对近年来机械取栓装置相关的技术演变和临床试验进行了综述。

At present, intravenous thrombolysis within 4.5 h is still the most effective method in treatment of acute ischemic stroke. For those who do not meet the criteria of intravenous thrombolytic therapy, do not have significant improvement after intravenous thrombolysis and even worse, endovascular interventional therapy is a safe alternative treatment method. Arterial mechanical thrombectomy devices can achieve rapid and complete recanalization and provide more treatment options for patients with acute ischemic stroke. This article reviews the related technical evolution and clinical trials of mechanical thrombectomy devices.
