Summary
Prompt repair of knee vascular injuries, including popliteal artery and vein, alongside early fasciotomy, is crucial. Vein repair offers better long-term outcomes than ligation for these traumatic injuries.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Orthopedic Surgery
Background:
- Knee vascular injuries are complex, often associated with fractures and nerve damage.
- Popliteal artery and vein injuries present significant challenges in trauma management.
- Etiologies range from penetrating (gunshot, stab) to blunt trauma.
Purpose of the Study:
- To analyze outcomes of vascular injuries around the knee.
- To identify factors correlating with successful management and limb salvage.
- To compare different surgical techniques for arterial and venous repair.
Main Methods:
- Retrospective analysis of 41 patients with 43 knee vascular injuries.
- Review of injury types, associated injuries, and management strategies (arterial/venous repair, fasciotomy).
- Assessment of amputation rates and patient mortality.
Main Results:
- Popliteal artery injuries were most common (34/43), followed by tibial-peroneal trunk (5/43).
- High rates of associated fractures (67%), venous (54%), and nerve (32%) injuries.
- Amputation rate was 11% for popliteal artery injuries, linked to massive injury or delay; one death occurred due to renal failure.
- Successful management correlated with prompt arterial and venous repair and early fasciotomy.
Conclusions:
- Timely surgical intervention for popliteal arterial and venous injuries is critical for limb salvage.
- Vein repair demonstrates superior long-term results compared to ligation.
- Early fasciotomy is essential in managing these complex knee vascular traumas.
