Lumbar myelography with Omnipaque (iohexol).

Area of Science:

• Radiology
• Neurology
• Pharmacology

Background:

• Low back pain and sciatica are common conditions requiring diagnostic imaging.
• Lumbar myelography is a key diagnostic tool for evaluating spinal canal abnormalities.
• Iohexol (Omnipaque) is a non-ionic contrast agent used in myelography.

Purpose of the Study:

• To evaluate the safety and adverse reactions of iohexol lumbar myelography.
• To assess the incidence of side effects in patients undergoing the procedure for low back pain or sciatica.

Main Methods:

• 103 adult patients with low back pain or sciatica underwent lumbar myelography using iohexol.
• Patients were monitored for 48 hours post-procedure for adverse reactions.
• Electroencephalography (EEG) was performed on a subset of patients (n=25).

Main Results:

• 24 out of 103 patients (approximately 23%) experienced mild to moderate transient side effects.
• No serious adverse reactions were reported during the observation period.
• EEG recordings showed no significant changes in the monitored patients.

Conclusions:

• Iohexol lumbar myelography appears to be a safe procedure with a low incidence of mild, transient side effects.
• The contrast agent iohexol is well-tolerated in patients undergoing diagnostic lumbar myelography.
• Further research could explore long-term outcomes and compare iohexol with other contrast agents.
