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

Figure 2 Operative procedure: Patient 2. A: Digital subtraction angiography (DSA) revealing left middle cerebral artery (LMCA)-M1 segment occlusion (arrow); B: DSA revealing good recanalization of the M2 segment upper (arrow) and lower branch occlusions; C: The stent was deployed and retrieved without stent imaging (arrow); D: Angiogram revealing no recanalization postoperatively (arrow); E: The stent was redeployed at the distal M2 segment with a partial development of stent imaging; F: DSA after stent deployment revealing good recanalization of the LMCA-M2 segment (arrow).
