| Outline of Final Research Achievements |
To determine clinical utility of laser speckle flow imaging (LSFI), I used LSFI to monitor cerebral blood flow (CBF) as a complementary method for the management of during several kinds of neurosurgery. Intraoperative intensity of CBF by LSFI was measured with mass lesion-related arteries and brain tumor or arterovenous malformation. LSFI device-mounted microscope was centered over the surgical field, and the relative CBF before and after the temporary interruption of the arteries was measured through continuous recording. LSFI clearly demonstrated a decrease in CBF, the information is taken only from the surface of the brain. To recognition of mass lesion-related vasculature, LSFI can be used to avoid ischemic complications as procedure complementary to neurophysiological monitoring.
