[Cerebral Embolism:Endovascular Techniques and Devices]

Thrombectomy has proven its efficacy in several randomized clinical trials. Although considerable clinical evidence supports its efficacy, the optimal device or technique has not been proven. There is a diversity of devices and techniques; therefore, we need to know about them and choose suitable ones. Recently, a combined technique with a stent retriever and aspiration catheter has become common. However, no evidence to support the superiority of the combined technique in improving patient outcomes compared with the stent retriever alone.
