Figure 6: Local hemodynamics in a patient with carotid occlusion before and after the bypass - high risk for local hyperperfusion syndrome. (a) Blood flow velocity in the cortical artery before the bypass, <10 cm/s; (b) Blood flow velocity in the bypass, 50 cm/s; (c) Measurement of blood flow at the distal part of anastomosed site in the recipient artery, blood flow >30 cm/s. The distal direction of blood flow. US marker of local hyperperfusion; (d) Measurement of blood flow at the proximal part of the anastomosed site in the recipient artery, blood flow >55 cm/s. The reverse of blood flow – proximal direction of blood flow
