|June 1, 1989
Summary
Outpatient myelography using iohexol is safe and effective, with a low rate of side effects (19%) compared to older agents like metrizamide. This procedure is feasible when iohexol is used and patient surveillance is well-organized.
Area of Science:
- Radiology
- Neurology
- Medical Imaging
Background:
- Myelography is a diagnostic imaging procedure.
- Previous studies reported varying side effect profiles with different contrast agents.
Purpose of the Study:
- To evaluate the safety and feasibility of outpatient myelography using iohexol (Omnipaque).
Main Methods:
- Outpatient myelography was performed in 150 patients using iohexol.
- Adverse events were systematically recorded and analyzed.
Main Results:
- 19% of patients experienced side effects, with only 2% reporting major complaints (headache, seizures).
- Side effect rates were comparable to hospitalized patients and significantly lower than with metrizamide.
- Headache was the most common side effect, followed by ischiatiform pain, nausea, and vomiting.
Conclusions:
- Outpatient myelography with iohexol is a feasible procedure.
- Careful patient surveillance is crucial for successful outpatient myelography.
