本文对1095例病人的2770条脑供血动脉进行了动脉内灌注研究。DSA.连续性神经功能缺损发生率为0.09%，一过性神经功能缺损发生率为0.45%。与以前的研究相比，并发症发生率降低似乎是技术进步（DSA）和使用新的等渗造影剂的持续影响。为了减少“训练医院效应”，如并发症发生率，仔细监督受训者是必要的。建议将每根血管的平均透视时间作为神经放射科医生研究技能的客观指标。
SummaryIn 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.
