Intraoperative flow data was collected, including STA cut-flow, bypass flows, and cut flow index (CFI). Bypass patency was assessed by cerebral angiography and quantitative magnetic resonance angiography with noninvasive optimal vessel analysis. Adverse events occurring during the hospital stay and clinical status at last follow up was recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      Seven patients underwent SVDA bypass. Mean follow-up was 14.5 mo. Initial CFI for the S2S bypasses averaged 0.56\u00a0\u00b1\u00a00.25 and CFI after the SVDA averaged 1.15\u00a0\u00b1\u00a00.24. There was a statistically significant average difference in CFI before and after the SVDA bypass (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u00a0&lt;\u00a0.013). Thirteen bypasses (93%) were patent postoperatively, and remained patent at last follow up. Four patients experienced various postoperative complications.
