A: Initial magnetic resonance imaging indicated a small left frontal infarction from the left middle cerebral artery (MCA) stenosis (yellow arrow); B: On the transfemoral cerebral angiography (TFCA), the left superficial temporal artery was thin with weak flow (yellow arrow); however, the occipital artery (OA) was prominent (black arrows); C-F: After the OA-MCA bypass, blood flow at the surgical site was intact on postoperative TFCA (D and E; yellow arrow), with a perfusion defect improvement on postoperative Diamox SPECT compared with the preoperative scan (C and F; yellow arrows).
