The role of quantitative hemodynamic magnetic resonance imaging in the surgical revascularization of cerebral tissueŠebök, Martina (Avtor) surgical cerebral revascularizationSTA-MCA bypasscerebrovascular steno-occlusive diseasecerebral hemodynamicsfunctional magnetic resonance imagingThe goal of surgical revascularization of brain tissue is to improve cerebral perfusion in patients with cerebrovascular stenotic-occlusive disease, where certain regions of the brain are hypoperfused. The most commonly performed procedure, anastomosis between the superficial temporal artery and middle cerebral artery (STA-MCA bypass), is indicated in moyamoya vasculopathy, in selected cases of chronic stenotic-occlusive disease, and in acute ischemic stroke with hemodynamic impairment. Quantitative hemodynamic assessment plays a key role in selecting candidates for the procedure. Among modern non-invasive methods for assessing cerebral hemodynamics, blood oxygenation-level dependent cerebrovascular reactivity (BOLD-CVR) stands out. This special form of magnetic resonance imaging allows detection of regions with reduced vasodilatory capacity, thereby identifying hemodynamically endangered brain tissue. This article presents the current indications and decision-making processes in selecting patients for surgical revascularization of the brain, as well as institutional experiences in patient selection based on BOLD-CVR. The critical importance of this method for successful planning and execution of revascularization is emphasized, as it significantly contributes to optimizing surgical and clinical outcomes.20262026-08-18 10:03:37Znanstveno delo99472sl
