Venous function five to eight years after clinically suspected deep venous thrombosis
Acta Medica Scandinavica
|January 1, 1985
Summary
Deep venous insufficiency (DVI) is common even without deep venous thrombosis (DVT). Over a third of legs without prior DVT developed DVI, highlighting the importance of popliteal vein health.
Area of Science:
- Vascular Medicine
- Medical Diagnostics
- Clinical Research
Background:
- Deep venous thrombosis (DVT) can lead to long-term complications.
- Deep venous insufficiency (DVI) is a potential sequela of DVT.
- Understanding the prevalence and risk factors for DVI is crucial for patient management.
Purpose of the Study:
- To evaluate the frequency of deep venous insufficiency (DVI) in patients with a history of suspected deep venous thrombosis (DVT).
- To identify factors associated with the development of DVI.
- To assess DVI in legs with and without confirmed prior DVT.
Main Methods:
- Retrospective investigation of 154 patients 5-8 years post-phlebography.
- Clinical examination, subjective complaint registration, and objective measurements including plethysmography, venous pressure, and Doppler ultrasound.
- Comparison of DVI prevalence between legs with and without a history of DVT.
Main Results:
- Deep venous thrombosis (DVT) was present in 75 legs.
- No significant difference in DVI between legs with and without prior DVT, except for more venous outflow obstruction in those with DVT.
- DVI occurred equally after calf and proximal DVT, and was more frequent in elderly patients or those with prior DVI/DVT.
- Popliteal vein sufficiency was critical for DVI development.
- Over one-third of legs without DVT developed DVI.
Conclusions:
- Deep venous insufficiency (DVI) can develop even in the absence of deep venous thrombosis (DVT).
- Popliteal vein status is a key factor in the development of DVI.
- Regular monitoring and management strategies are important for patients with or at risk of DVI.
