Summary
Surgical repair of lower extremity venous injuries shows high patency for femoral and popliteal veins. However, infrapopliteal venous repair is not recommended due to poor outcomes and low blood flow velocities.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Vascular Ultrasound
Background:
- Lower extremity vascular injuries often result from trauma.
- Venous repair patency is crucial for limb salvage and function.
- Quantitative assessment of venous repair outcomes is needed.
Purpose of the Study:
- To quantitatively investigate the patency of venous repair after lower extremity trauma.
- To measure vein blood flow velocities in repaired vessels.
- To evaluate the impact of injury severity and repair technique on outcomes.
Main Methods:
- Prospective study of 130 patients with lower extremity vascular injuries over 10 years.
- Duplex color ultrasonography used for patency and blood flow velocity measurements.
- Analysis of various venous repair techniques and their long-term patency rates.
Main Results:
- Repaired femoral and superficial femoral veins demonstrated high patency rates (100% and 89% at 1 year).
- Popliteal vein repair had lower patency (86% at 1 year, 60% at 6 years).
- Infrapopliteal venous repair showed extremely poor patency (<5 cm/s flow velocity, high occlusion rates).
Conclusions:
- Venous repair is effective for femoral and popliteal injuries.
- Repair of infrapopliteal venous injuries is associated with poor outcomes and is deemed unnecessary.
- Flow velocity is a critical determinant of venous repair success.
