She underwent trapping of the ICA with HFB using the radial artery and an additional assist STA-MCA bypass. Preoperative composite images from three-dimensional digital subtraction angiography and digital subtraction venography enabled localization of the cortical recipient artery relative to identifiable veins. Intraoperative indocyanine green (ICG) videoangiography confirmed the recipient artery\u2019s flow characteristics. Both bypasses remained patent, and postoperative MRI showed no ischemic complications.
