Four-vessel angiography was repeated in 56 patients with confirmed subarachnoid hemorrhage in whom the initial investigation was negative. Only one aneurysm was demonstrated. The results suggested that, with good technique, careful observation, and a complete four-vessel cerebral angiography, a false negative rate of less than 2% can be achieved. It is suggested that to repeat pan-angiography is seldom justified unless further bleeding episodes occur.
对56例确诊为蛛网膜下腔出血但初次检查结果为阴性的患者再次进行了四血管造影。仅发现1个动脉瘤。结果表明，采用良好的技术、仔细观察并进行完整的四血管脑血管造影，假阴性率可低于2%。建议除非再次发生出血事件，否则很少有理由重复进行全血管造影。
