S75.122 Major laceration of femoral vein at hip and thigh level, left leg

Name of the Condition

• Major laceration of femoral vein at hip and thigh level, left leg

Summary

A major laceration of the femoral vein at the hip and thigh level, left leg, involves a significant tear or cut to the femoral vein, a major venous structure in this region. This condition typically results from trauma and may cause substantial bleeding, vascular compromise, or thrombosis. Prompt evaluation is necessary to assess the extent of injury and guide appropriate management to prevent complications such as hemorrhage, infection, or limb ischemia.

Causes

Direct trauma to the hip or thigh, such as from penetrating injuries (e.g., stab wounds, gunshot wounds) or blunt force (e.g., motor vehicle accidents, severe falls). Iatrogenic injury during medical procedures involving the femoral vein, such as catheterization or surgery. Severe fractures or dislocations of the hip or femur that may damage the adjacent vein.

Risk Factors

• Participation in high-risk activities with potential for lower extremity trauma (e.g., contact sports, combat).
• Proximity to penetrating or blunt force events.
• Pre-existing venous conditions that may weaken the vessel (e.g., varicosities, thrombophlebitis).
• Advanced age, which may increase susceptibility to injury or vascular fragility.
• Use of anticoagulant or antiplatelet medications, which can exacerbate bleeding.

Symptoms

• Visible, profuse bleeding from the injury site.
• Swelling, pain, or tenderness in the hip or thigh region.
• Possible discoloration or bruising around the affected area.
• Signs of vascular compromise, such as coolness, pallor, or diminished pulses in the left leg.
• Numbness, tingling, or weakness in the left leg due to impaired blood flow.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including assessment of the injury site and vascular status. Imaging studies, such as ultrasound or CT angiography, may be used to visualize the extent of the laceration and assess for associated complications like thrombosis or hematoma. Laboratory tests, including complete blood count and coagulation studies, help evaluate bleeding severity and clotting function.

Treatment Options

Treatment focuses on controlling bleeding and restoring vascular integrity. This may include direct pressure, surgical repair of the laceration, or endovascular interventions. Anticoagulant therapy may be initiated to prevent thrombosis, while antibiotics are administered if infection is suspected. Pain management and monitoring for complications are also critical components of care.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, timeliness of treatment, and presence of complications. Most patients recover with appropriate management, but delayed treatment or severe vascular damage may lead to long-term issues like chronic venous insufficiency or limb dysfunction. Follow-up care includes monitoring for signs of infection, thrombosis, or impaired circulation, with repeat imaging if symptoms persist.

Complications

• Hemorrhage, which may be life-threatening if not controlled promptly.
• Thrombosis or embolism due to vessel damage or stasis.
• Infection at the injury site or within the vascular system.
• Chronic venous insufficiency or post-thrombotic syndrome.
• Limb ischemia or tissue damage from reduced blood flow.

Lifestyle & Prevention

Avoid high-risk activities that increase the likelihood of trauma to the hip or thigh. Use protective gear during sports or hazardous work. Manage pre-existing venous conditions and follow medical advice when using anticoagulants. Promptly address any injuries to the lower extremities to reduce complication risk.

When to Seek Professional Help

Seek immediate medical attention for visible bleeding, severe pain, swelling, or signs of limb ischemia (e.g., coolness, numbness, or discoloration). Delayed evaluation may worsen outcomes, especially if bleeding or vascular compromise is present.

Tips for Medical Coders

Document the laterality (left leg) and the nature of the injury (major laceration) to ensure accurate coding. Include details about the mechanism of injury, associated fractures, or iatrogenic causes if applicable. Verify that the documentation supports the specificity of the code and aligns with clinical findings.
