Blood Flow Assessment of Arteriovenous Malformations Using Intraoperative Indocyanine Green Videoangiography

Figure 2

Comparison of parameters according to vessel types. Maximum intensity (a), delay time (b), and CBFi (c). Values showed absence of significant differences among the vessel types. The CBFi value of the feeders was significantly higher in the niduses of > 3-cm diameter (d). In addition, the CBFi of the feeders was correlated with the cubage of the nidus (e). Representative time-intensity diagrams presenting three different patterns according to the nidus volume (f). CBFi: cerebral blood flow index.
