ABSTRACT
The authors performed prospectively the transcranial Doppler monitoring of middle cerebral arteries in 37 patients with ruptured cerebral aneurysm. The entry criteria for the study were confined to the patients who had clinical Grades of 1, 2, or 3, and were operated within 4 days after bleeding. There were several sonographic risk factors of developing delayed ischemic deficits; 1) An early steep increase of flow velocity exceeding 120 cm/sec. 2) An increase of maximum flow velocity more than 140 cm/sec. 3) The flow velocity increasing simultaneously with the onset of delayed ischemic deficit in which case preventive treatment was impossible. 4) Prolonged elevation of flow velocity for more than 7 days despite of aggressive treatment. It seemed to be mandatory to start preventive and aggressive treatment for the asymptomatic patients who showed higher flow velocity than 140 cm/sec. Transcranial Doppler sonography has another potential on deciding the timing of surgery.
