[Lumbar phlebography: anatomy and technique (author's transl)]

Area of Science:

• Radiology
• Vascular Anatomy
• Medical Imaging

Background:

• Accurate interpretation of venographic studies relies on understanding normal epidural venous anatomy.
• The epidural venous plexus is a complex network crucial for spinal imaging.
• Standardized visualization techniques are essential for diagnostic accuracy.

Purpose of the Study:

• To describe the normal radiological anatomy of epidural veins.
• To evaluate and compare different methods for visualizing the epidural venous plexus.
• To identify the most effective technique based on visualization quality, time, cost, and radiation exposure.

Main Methods:

• Description of normal epidural venous anatomy.
• Detailed explanation of three distinct techniques for epidural venous plexus visualization.
• Comparative analysis of techniques based on 80 patient cases.
• Assessment criteria included visualization degree, procedure time, cost-effectiveness, and radiation dose for patients and operators.

Main Results:

• The study reports experience with 80 cases, comparing three visualization techniques.
• Quantitative and qualitative data were collected on visualization effectiveness, time, cost, and radiation exposure.
• Simultaneous contrast media injection via two needles in the right and left femoral veins was found to be preferable.

Conclusions:

• Understanding normal epidural vein anatomy is fundamental for venographic interpretation.
• Simultaneous bilateral femoral vein injection offers advantages in visualizing the epidural venous plexus.
• The preferred technique balances diagnostic yield with patient and operator safety considerations.
