Complications of phlebography: a randomised comparison between an ionic and a non-ionic contrast medium

Area of Science:

• Vascular Surgery
• Radiology
• Medical Imaging

Background:

• Recent reports suggest high thrombotic complications with ionic contrast media during phlebography.
• A switch to non-ionic contrast media has been recommended, potentially limiting phlebography use.

Purpose of the Study:

• To prospectively compare thrombotic complications between ionic and non-ionic contrast media in phlebography.
• To evaluate the clinical significance of immediate side-effects associated with ionic media.

Main Methods:

• Prospective study including patients undergoing phlebography for varicose veins.
• Comparison of ionic versus non-ionic contrast media.
• Post-phlebographic assessment using microscopy of vein specimens and plethysmography.

Main Results:

• No significant difference in thrombotic complications was observed between the two contrast media groups.
• Ionic media showed a higher incidence of immediate side-effects like pain, which are clinically less critical.
• Immediate side-effects from ionic media can be mitigated with proper phlebographic technique.

Conclusions:

• Phlebography with ionic contrast media is justifiable, particularly for patients without a history of thrombotic disease.
• Optimal technique, including short examination time and low contrast dose/concentration, is crucial when using ionic media.
• Ionic contrast media remain a viable option for phlebography, balancing efficacy and cost-effectiveness.
