Summary
Deep venous insufficiency is common, affecting nearly half of patients with suspected deep vein thrombosis and many without symptoms. Combined femoral and popliteal vein involvement is most prevalent.
Area of Science:
- Vascular Medicine
- Diagnostic Imaging
Background:
- Deep venous insufficiency is a significant vascular condition.
- Accurate diagnosis is crucial for patient management.
Purpose of the Study:
- To determine the prevalence, location, and clinical features of deep venous insufficiency in lower extremities.
- To assess the diagnostic utility of sonography in identifying venous insufficiency.
Main Methods:
- Randomized study of 224 patients (380 lower extremities).
- Examination using color duplex and triplex sonography.
- Analysis of prevalence and clinical manifestations of deep venous insufficiency.
Main Results:
- Only 21.1% of patients with suspected deep vein thrombosis had objective signs.
- Deep venous insufficiency was found in 47.7% of patients with clinical signs and 59.9% without symptoms.
- Combined insufficiency of femoral and popliteal veins (99.8%) was the most common finding.
Conclusions:
- Deep venous insufficiency is frequently undiagnosed in patients presenting with lower extremity symptoms.
- Sonography is effective in detecting venous insufficiency, even in asymptomatic individuals.
- Combined femoral and popliteal venous insufficiency is highly prevalent.
