The hemodynamic parameters of the internal maxillary artery (n\u2009=\u200920), radial artery (n\u2009=\u200920), internal maxillary artery\u2013middle cerebral artery bypass (n\u2009=\u200942), and internal maxillary artery\u2013posterior cerebral artery bypass (n\u2009=\u20099) were measured by intraoperative duplex sonography. There was no significant difference in the internal diameters of the internal maxillary and radial arteries (mean\u2009\u00b1\u2009SD, 2.51\u2009\u00b1\u20090.34 versus 2.56\u2009\u00b1\u20090.22 mm; <jats:italic>P<\/jats:italic>\u2009=\u2009.648). The mean radial artery graft length for subcranial\u2013intracranial bypasses was 88.5\u2009\u00b1\u200912.78 mm (95% confidence interval [CI], 80.8\u201390.2 mm). Internal maxillary artery\u2013middle cerebral artery bypasses required a shorter radial artery graft than internal maxillary artery\u2013posterior cerebral artery bypasses (77.8\u2009\u00b1\u20092.47 versus 104.8\u2009\u00b1\u20094.77 mm; <jats:italic>P<\/jats:italic>\u2009=\u2009.001). The mean flow volumes were 85.3\u2009\u00b1\u200918.5 mL\/min (95% CI, 76.6\u201393.9 mL\/min) for the internal maxillary artery, 72.6\u2009\u00b1\u200926.4 mL\/min (95% CI, 64.3\u201380.9 mL\/min) for internal maxillary artery\u2013middle cerebral artery bypasses, and 45.4\u2009\u00b1\u20096.7 mL\/min (95% CI, 40.7\u201350.0 mL\/min) for internal maxillary artery\u2013posterior cerebral artery bypasses. All grafts were opened after the success of the salvage procedures had been established, and the early patency rates (1 month after the operation) were 95% for internal maxillary artery\u2013middle cerebral artery bypasses and 100% the internal maxillary artery\u2013posterior cerebral artery bypasses. Measurement of blood flow by intraoperative sonography can be helpful in decision making and predicting graft patency and success after neurosurgical bypass
