Image-based visualization of stents in mechanical thrombectomy for acute ischemic stroke: Preliminary findings from a series of cases

Figure 3 Operative procedure: Patient 3. A: Digital subtraction angiography (DSA) revealing distal right internal carotid artery-C7 segment occlusion with poor collateral circulation (arrow); B: Stent deployed and retrieved at the proximal right middle cerebral artery (RMCA)-M1 segment without stent imaging (arrow); C: After removing a thrombus, the DSA showed that the RMCA-M2 segment upper branch remained occluded (arrow); D: Stent-based mechanical thrombectomy can be observed (arrow); E: Local enlarged stent imaging showing strip-shaped distribution (arrow); F: Repeat DSA revealing good recanalization of the RMCA.
