 STA-MCA bypass could directly improve the cerebral blood supply without affecting the hemodynamics of other arteries, such as BA and ICA.
Figure.1 Visual assessment of patency of STA-MCA bypass using 4D Flow MRI. Time-of flight magnetic resonance angiography (MRA) (A, B) and 4D Flow MRI (C, D) were performed preoperatively (A and C) and 7 days after bypass surgery (B and D). The yellow arrows indicated the locations of STA used to STA-MCA bypass.
