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

Figure 1 Operative procedure: Patient 1. A: Digital subtraction angiography (DSA) revealing proximal basilar artery (BA) occlusion (arrow); B: Stent deployed at the left posterior cerebral artery (LPCA)-P1 segment and BA (without stent imaging, arrow); C: DSA revealing the upper part of the BA occlusion (arrow); D: Stent deployed in the proximal region of the right posterior cerebral artery (RPCA)-P1 segment to capture the thrombus; E: DSA revealing the RPCA and LPCA-P1 segment proximal occlusion (arrow); F: Stent placed in the distal LPCA-P1 segment (without stent imaging, arrow); it was unable to capture a thrombus; G: Stent deployed at the LPCA-P2 segment and stent imaging presenting a grid-form shadow; H: Stent capturing three fragmented thrombi; I: Repeat DSA revealing good recanalization.
