The purpose of this study was to clarify the change in the hemodynamics after superficial temporal artery to middle cerebral artery (STA-MCA) bypass surgery using 4D Flow MRI. We enrolled 20 patients who underwent 4D Flow MRI preoperatively and 3 weeks after the surgery. The blood flow volume (BFV) of ipsilateral STA and ipsilateral ICA significantly increased after the surgery (0.53±0.22 vs. 1.78±0.54 ml/sec (p< 0.001); 2.37±5.09 vs. 1.82±3.42 ml/sec (p=0.03)). While, no significant difference was observed in total-BFV (p = 0.24). It may indicate that ipsilateral STA and intracranial native artery supply blood flow complementarily after surgery.
