Metrizamide is a water-soluble, nonionic radiocontrast medium that penetrates better into narrow subarachnoid spaces than do oily contrast media or gas. We performed metrizamide optic nerve thecography on five cats with iatrogenic orbital lesions. Optic thecograms successfully demonstrated displacement of the optic nerve, obstruction of the optic nerve sheath subarachnoid space, and extravasation of the contrast medium from a punctured optic nerve sheath. Metrizamide-induced seizures could be prevented by intramuscular preadministration of diazepam.
甲泛葡胺是一种水溶性非离子型造影剂，与油性造影剂或气体相比，它能更好地渗透到狭窄的蛛网膜下腔。我们对五只患有医源性眼眶病变的猫进行了甲泛葡胺视神经鞘造影。视神经鞘造影成功地显示了视神经的移位、视神经鞘蛛网膜下腔的阻塞以及造影剂从穿刺的视神经鞘外渗。肌肉注射地西泮可预防甲泛葡胺引起的癫痫发作。
