The results of 5184 carotid angiograms were reviewed and five cases of intracranial extravasation of contrast medium were found. In two cases an aneurysm ruptured during angiography and extravasation into the subarachnoid space was seen. In one case medium leaked from an angiomatous malformation into the subdural space. The fourth case was a patient who had suffered closed head trauma. Here extravasation was seen deep within the brain. The fifth case illustrates two forms which extravasation from meningeal arteries may take. The incidence and prognostic significance of this finding in different conditions are discussed.
回顾了5184例颈动脉血管造影的结果，发现5例造影剂颅内外渗。其中2例动脉瘤在血管造影时破裂，可见造影剂外渗至蛛网膜下腔。1例造影剂从血管畸形漏入硬膜下腔。第4例是一名闭合性颅脑外伤患者，在脑深部可见造影剂外渗。第5例说明了脑膜动脉外渗可能出现的两种形式。讨论了在不同情况下这一发现的发生率及预后意义。
