The major changes in clinical condition during and after encephalography may be explained by intracranial pressure variations. If neither intracranial hypertension nor CSF dynamic perturbations exist, minimal complications may be predicted, but in intracranial hypertension immediate deterioration may occur. Despite an apparently good level of tolerance, complications may develop if the compensation phenomena cannot occur: normal pressure hydrocephalus, craniosynostosis. In the cases with good clinical tolerance, minimal changes occur when air injection is administered at a slow rate and with a small volume.
脑造影期间及之后临床状况的主要变化可能由颅内压变化来解释。如果既不存在颅内高压也不存在脑脊液动力学紊乱，可预测并发症极少，但在颅内高压情况下可能会立即出现病情恶化。尽管耐受性水平看似良好，但如果代偿现象无法发生，仍可能出现并发症：正常压力脑积水、颅缝早闭。在临床耐受性良好的病例中，缓慢且少量注入空气时发生的变化极小。
