Primary suction [[thrombectomy]] produced higher [[recanalization]] and good clinical outcome rates than did [[stent retriever]] thrombectomy. Larger-scale studies are necessary that consider factors such as occlusion site, stroke severity, and concomitant use of endovascular devices ((Jeon JP, Kim SE, Kim CH.
