In 1095 patients 2770 brain supplying arteries have been studied by i.a.-DSA. Definitive neurological deficits occurred in 0.09%, transient deficits were observed in 0.45%. The reduced complication rate in comparison to former studies seems to be a continued effect of technical progress (DSA) and the use of new isoosmotic contrast media. In order to reduce the "training hospital effect" as to complication rate careful supervision of trainees is necessary. The average fluoroscopy time per vessel is proposed as an objective measure of the investigational skill of a neuroradiologist.
对1095例患者的2770条脑供血动脉进行了动脉数字减影血管造影（i.a.-DSA）研究。明确的神经功能缺损发生率为0.09%，短暂性缺损发生率为0.45%。与以往研究相比，并发症发生率降低似乎是技术进步（DSA）和使用新型等渗造影剂的持续效果。为降低并发症发生率方面的“教学医院效应”，有必要对实习生进行仔细监督。建议将每条血管的平均透视时间作为衡量神经放射科医生检查技能的客观指标。
