Figure 4.

A 74-year-old man was presented with mild right-sided paralysis, aphasia, and a National Institutes of Health Stroke Scale score of 9. (a) The DWI indicated a faint high signal and the FLAIR detected nothing (circle). (b) Angiography demonstrating distal M2 occlusion (arrowhead). The occluded vessel diameter was 1.6 mm (white arrow). (c) The treatable tortuosity and pathway were revealed using 3D rotational angiography. We selected 1.4-mm outer diameter aspiration catheters. (d) The stent retriever (SR) deployed on the clots (arrowhead) as an anchor and the tip of the aspiration catheter (black arrow). (e) The aspiration catheter established contact with a clot via the assisted contact method. (f) Near-complete recanalization visualized by angiography. (g) Lack of hemorrhage on the CT. (h) Retrieved clot.
