Transfemoral lumbar epidural venography

Area of Science:

• Radiology
• Neurosurgery
• Diagnostic Imaging

Background:

• Myelography is a standard diagnostic tool for lumbar disc disease.
• Some cases of herniated discs are not clearly visualized by myelography.
• Accurate preoperative diagnosis is crucial for effective surgical planning.

Purpose of the Study:

• To evaluate the diagnostic accuracy of lumbar epidural venography.
• To determine the utility of lumbar epidural venography in cases with normal or nondiagnostic myelograms.
• To identify key venographic findings indicative of lumbar disc herniation.

Main Methods:

• Lumbar epidural venography was performed on 107 patients.
• Patients included those with normal or nondiagnostic myelograms.
• Diagnostic accuracy was compared to surgical findings.

Main Results:

• Lumbar epidural venography correctly diagnosed herniated disc disease in 92% (25/27) of patients.
• It diagnosed nerve root compression without disc herniation in 50% (3/6) of patients.
• The most significant abnormality was epidural or radicular vein compression/occlusion at the disc level.

Conclusions:

• Lumbar epidural venography is a valuable tool for diagnosing herniated lumbar discs not evident on myelography.
• Recognizing potential confounding findings is essential for accurate interpretation.
• This technique improves preoperative diagnostic accuracy for specific lumbar pathologies.
