The benefit of intraoperative mFV measurement for prediction of cerebral hyperperfusion after superficial temporal artery-middle cerebral artery (STA-MCA) bypass

Abstract

One of the most problematic complications of STA-MCA bypass is cerebral hyperperfusion (CHP). We studied the benefit of intraoperative mFV measurement for prediction of CHP after bypass surgery. A total of g patients with occlusive cerebrovascular disease (6 males and 3 females, mean age 61 years) underwent intraoperative measurement of STA mFV. In 2 patients, the mFV showed a significant 9-fold increase compared to the preoperative mFV, and postoperative SPECT also showed asymptomatic CHP on day 3. These results suggest the benefit of measurement of STA mFV for prediction of CHP.
