Local complications of ascending phlebography

Area of Science:

• Radiology
• Vascular Medicine

Background:

• Phlebography is a diagnostic imaging technique used to visualize veins.
• Assessing local complications associated with phlebography is crucial for patient safety.

Purpose of the Study:

• To estimate the rate of local complications following phlebography.
• To investigate the impact of contrast medium concentration on complication rates.

Main Methods:

• A one-year series of 477 patients undergoing phlebography was studied.
• Patients were divided into two groups, one receiving a highly concentrated contrast medium and the other a more diluted one.
• Complications were verified using biopsy, thermography, and plethysmography.

Main Results:

• Eight out of 477 patients experienced local complications.
• Complications included deep vein thrombosis (1), superficial thrombosis (5), and skin necrosis (2).
• Higher complication rates were observed with the more concentrated contrast medium (6 vs. 2).

Conclusions:

• While clinically significant complications from phlebography are infrequent, they necessitate careful consideration of procedural risks.
• Minimizing contrast medium concentration and exposure time is recommended.
• A hypothesis suggests extravasal contrast injection may cause arterial thrombosis, leading to slow-healing skin necrosis.
