Little has been reported on the flow volume of cortical arteries in the posterior circulation. During craniotomy in 28 patients, we measured the flow velocity of the arteries using microvascular Doppler sonography and recorded their arterial radii and the insonation angle. The flow velocities and radii were 25.7 cm sec-1 and 0.11 cm for the posterior cerebral artery (PCA), 19.5 cm sec-1 and 0.07 cm for the superior cerebellar artery (SCA), 19.6 cm sec-1 and 0.04 cm for the anterior inferior… CONTINUE READING
