The objective of this study was to investigate the efficacy and safety of a parietal branch of superficial temporal artery-interposed superficial temporal artery-to-ACA bypass (PISAB) for preventing stroke in patients with symptomatic atherosclerotic ACA stenosis or occlusion (SAASO).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively analyzed the data from patients with SAASO who had undergone PISAB in our center between April 2016 and November 2021. The rates of patency, satisfaction (revascularization grades A and B) of bypass, perioperative complications, recurrence of ischemic stroke, changes in bypass flow, and improvements in cerebral blood perfusion were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 19 SAASO patients were involved in this study. Sixteen out of 19 (84.2%) patients were free from any cerebral ischemic events after surgery. Only 3 patients (15.8%) had recurrent stroke postoperatively. Two (10.5%) surgery-related complications occurred, including hyperperfusion syndrome and minor stroke. No skin ischemic complications occurred. The average follow-up period was 50.6\u2009\u00b1\u200918.3\u2009months. The flow rate of the bypass was significantly increased half a year after surgery (56.2\u2009\u00b1\u20098.0\u2009mL\/min vs. 44.3\u2009\u00b1\u20095.3\u2009mL\/min, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.001). The ratio of ipsilateral\/contralateral mean transit time in the superior frontal gyrus was decreased significantly after bypass (1.08\u2009\u00b1\u20090.07 vs. 1.23\u2009\u00b1\u20090.05, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.001) and continued to decrease 6\u2009months after surgery (1.05\u2009\u00b1\u20090.04 vs. 1.08\u2009\u00b1\u20090.07, <jats:italic>p<\/jats:italic>\u2009=\u20090.002). The patency rate of PISAB was 94.7% (18\/19) 2\u2009years after surgery. The satisfaction rate of bypass was 89.5% (17\/19).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The results of this study indicate that PISAB, as a safe superficial bypass, can effectively reduce the risk of stroke in SAASO patients.
