Evaluation of Hemodynamic Change by Indocyanine Green-FLOW 800 Videoangiography Mapping: Prediction of Hyperperfusion Syndrome in Patients with Moyamoya Disease

<div>ICG was performed after a craniotomy to identify alternative recipient arteries in the surgical area (a). Color mapping was available to locate the hypoperfusion area for anastomosis. Regions of interest were set at the artery branch and parameters, such as cerebral blood flow (CBF, slope), cerebral blood volume (CBV, peak), and time to peak (TTP, delay time), which could be calculated and compared to confirm local cerebral hemodynamics for surgical decision making. Postoperative ICG-FLOW 800 was performed again (b) to confirm the patency of the anastomosis and to compare blood flow changes in the previously selected area.</div>
