Venous function in the leg after postoperative thrombosis diagnosed with 125I-fibrinogen uptake test

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Clinical Outcomes

Background:

• The 125I-fibrinogen uptake test (FUT) is a common method for detecting postoperative thrombosis.
• Positive FUT correlates with phlebography findings and a higher risk of pulmonary embolism.
• Long-term leg venous function after FUT-detected thrombosis is not well-documented.

Purpose of the Study:

• To evaluate the long-term predictive value of FUT for deep venous insufficiency.
• To assess if FUT-detected thrombosis indicates a higher risk for chronic venous problems.

Main Methods:

• Follow-up study of 179 patients 4-5 years after initial FUT testing.
• Utilized questionnaires, clinical examinations, venous strain-gauge plethysmography, venous pressure measurement, and phlebography.
• Compared outcomes between FUT-positive and FUT-negative legs.

Main Results:

• No statistically significant differences in venous function parameters were observed between FUT-positive and FUT-negative legs.
• The frequency of deep venous insufficiency was similar in both groups.
• Venous insufficiency rates were independent of the thrombus location detected by FUT.

Conclusions:

• FUT is not a reliable indicator of long-term risk for developing deep venous insufficiency.
• Postoperative thrombosis detected by FUT does not appear to impact long-term leg venous health.
• Clinical monitoring and further research into risk factors for venous insufficiency are warranted.
