A 72-year-old woman with a left hemi-paralysis, dysarthria, and anisocoria (NIHSS 22). She was treated initially with IV thrombolysis but did not recover and was referred to our department for EVT. Catheter angiography, AP projection, with contrast injection in the dominant right vertebral artery reveals a midlevel occlusion of the basilar artery (a, white arrow). Thrombus removal by means of an aspiration catheter was attempted as illustrated by a fluoroscopy image with vessel road map projection (b, with the black arrow at the level of the catheter tip at the proximal end of the thrombus). After thrombus aspiration, an AP projection angiogram showed successful recanalization with patency of the basilar artery (c)
