Cervical myelography with metrizamide using lumbar injection.

The technique, the quality of the films and the frequency of side effects are evaluated in 100 consecutive cervical myelographies with lumbar injection of metrizamide (Amipaque). The most frequent adverse effects were headache (47%) and nausea and vomiting (27%). EEG disturbances were recorded in 20 per cent. Due to special circumstances grand mal seizures and mental confusion occurred in one patient; this was the only major complication in altogether 260 cervical myelographies with lumbar injection.
