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

Figure 4

DSA showed occlusion of R-ACA and stenosis of R-MCA with moyamoya vessel formation (a). MR scan revealed old infarction on right temporal-occipital lobe (b, c). ASL confirmed hypoperfusion in the right hemisphere (d). Recipient artery was selected from five optional vessels from ICG-FLOW 800 mapping (e, g). Anastomosis was performed in vessel 3 (blue box), and hemodynamic analysis showed an obvious increase of ΔCBF and ΔCBV (f, h). Three days after the procedure, the patients suffered from an epileptic seizure and were controlled by benzodiazepine. MR follow-up confirmed HPS with the evidence of increasing blood flow but not new infarction (i, j).
