Evaluation of surgical revascularization procedure outcomes for adult Moyamoya disease: a computed tomography perfusion-based study

ConclusionHighlighting the utility of CTP, this study demonstrates its effectiveness in assessing postoperative cerebral hemodynamic changes in adult MMD patients. STA-MCA yielded a larger postoperative perfusion area and greater improvement compared to EDAS, suggesting CTP ’s potential to elucidate symptom variation between two surgical revascularization procedures.Critical relevance statementWe analyzed computed tomography perfusion parameters in pre- and postoperative adult Moyamoya disease patients undergoing superficial temporal artery-middle cerebral artery bypass and encephaloduroarteriosynangiosis. Our findings suggest computed tomography perfusion ’s potential in objectively elucidating symptom variations between these surgical revascularization approaches for MMD.Key points• Postoperative perfusion improvement is only confined to the operative area after EDAS.• Besides the operative area, postoperative perfusion in the ipsilateral frontal lobe and basal ganglia was also improved after STA-MCA.• The degree of perfusion improvement in each brain area in the STA-MCA group was generally greater than that in the EDAS group.Graphical Abstract
