The case histories of 107 dogs undergoing metrizamide myelography at two veterinary hospitals were reviewed. Twenty‐three variables, including body weight, injection site, dose of contrast medium, and medical complications during and after recovery from anesthesia, were submitted to statistical analysis by computer. Partial or generalized seizures were the most common medical complications, occurring in 54 percent of the dogs weighing more than 29 kg. Other less frequent medical complications were exacerbation of neurologic signs the day following myelography (11 percent), transient apnea during contrast medium injection (9 percent), vomiting (5 percent), hyperesthesia (3 percent), pyrexia (1 percent), and death (1 percent). The incidence of medical complications associated with metrizamide myelography in this study is higher than in previous reports. The most likely variables associated with seizures were high injection volumes and metrizamide injection at the cisterna magna. The preanesthetic administration of intramuscular pentobarbital did not significantly reduce seizure incidence. Seizures were controlled by anticonvulsant medication.
