Figure 3 Cerebral digital subtraction angiography. A: Preoperative digital subtraction angiography (DSA), showing which revealed severe stenosis (approximately 80%) in the M1 segment of the right middle cerebral artery (MCA) (arrow); B: Intraoperative DSA Angiography after dilation, showing the vessel wall appeared irregular, the remaining branches showed good opacification (arrow); C: DSA Re-examination 6 months post-surgery, showing no significant stenosis in the right MCA, with a smooth vessel wall (arrow).
