抄録: The authors describe direct measurement of optic nerve blood flow and examine application of such monitoring to detect optic nerve ischemia during parasellar tumor surgery. Twenty-six patients requiring surgery for parasellar tumors were evaluated prospectively. Ophthalmologic examination was performed before and after surgery. The optic nerve blood flow was measured using a laser Doppler flowmeter before tumor dissection (initial ONBF) and after tumor removal (final ONBF). The waveform was analyzed by a data acquisition system. In 16 patients, initial ONBF could be measured (22 nerves; 8.9±0.9 ml/100 g/min). Final ONBF could be determined in all 26 patients (42 nerves; 10.8±0.7 ml/100 g/min). In the 22 nerves with initial measurements, final ONBF (11.3±0.6 ml/100 g/min) was significantly increased (p<0.01). In 6 patients whose optic canal was unroofed, the optic nerve blood flow did not change immediately; nonetheless, an increase was prominent in the final phase (p<0.05). In another 6 patients, a small vessel adjacent to the optic nerve was temporarily occluded. The optic nerve blood flow was reduced demonstrably in 3 and recovered quickly after reperfusion. Intraoperative optic nerve blood flow measurement may be useful as a real-time monitoring for prediction and prevention of intraoperative optic nerve ischemia.
