“Pial synangiosis”—a modification to the traditional encephaloduroarteriosynangiosis (EDAS) procedure, as advocated by Scott and associates.54 The original EDAS procedure involved suturing the superficial temporal artery (STA) to the dural edges without opening the arachnoid. Scott and colleagues modified the EDAS procedure by widely opening the arachnoid and directly suturing the adventitia of the STA to the cortical pia, in an effort to promote maximal exposure of the cortical surface to the overlying STA.
