Intraoperative contrast-enhanced ultrasound evaluates the hemodynamic change of cerebral revascularization in adult moyamoya disease: Preliminary results

•For the first time, we employed intraoperative contrast-enhanced ultrasound to observe the hemodynamic change of the subcortical brain tissue in patients with moyamoya disease following cerebrovascular bypass.•Through quantitative analysis of contrast-enhanced ultrasound, we discovered a correlation between hemodynamic parameters and the modified Rankin Scale scores of the patients. This suggests that quantitative contrast-enhanced ultrasound has the potential to predict neural function recovery after combined revascularization in moyamoya disease patients.
