Fig. 1 Preoperative axial (A), sagittal (B), coronal (C), and postoperative sagittal (D, E), axial (F), and 3D reconstructed computerized tomography angiography of the patient. 3D, three-dimensional; RA: radial artery, RA-to-M2: radial artery to M2 superior trunk anastomosis.

Fig. 2 Intraoperative photomicrographs showing the common carotid artery to radial artery interposition graft anastomosis (A); radial artery to M2 superior trunk anastomosis (B) and photomicrograph of the indocyanine green video angiography (C); view of the supraclinoidal internal carotid artery, distal dural ring, optic nerve, and aneurysm after extradural anterior clinoidectomy (D); the relationship of the aneurysm with the posterior communicating artery (E); decompressed optic nerve after complete trapping and incision of the aneurysm. ICA, internal carotid artery; PCoA, posterior communicating artery; PCoA, posterior communicating artery.
