S75.022 Major laceration of femoral artery, left leg

Name of the Condition

• Major laceration of femoral artery, left leg

Summary

A major laceration of the femoral artery in the left leg refers to a significant tear or disruption of the femoral artery, a major blood vessel in the thigh. This condition typically involves substantial damage to the arterial wall, leading to severe bleeding, compromised blood flow, or vascular instability. Prompt medical intervention is critical to control hemorrhage and restore perfusion to the affected limb.

Causes

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

Risk Factors

• Participation in high-risk activities with potential for severe thigh trauma (e.g., combat, high-impact sports).
• Proximity to penetrating or blunt force events with significant force.
• Preexisting vascular conditions that may weaken the artery (e.g., advanced atherosclerosis, aneurysms).
• Use of anticoagulant or antiplatelet medications, which can exacerbate bleeding.

Symptoms

• Profuse bleeding or expanding hematoma in the thigh or groin area.
• Severe pain, swelling, or tenderness at the injury site.
• Weakness, numbness, or pallor in the left leg due to reduced blood flow.
• Signs of shock (e.g., dizziness, rapid heart rate, low blood pressure) in severe cases.

Diagnosis

Diagnosis involves a thorough physical examination to assess bleeding, limb perfusion, and neurovascular status. Imaging studies, such as Doppler ultrasound, CT angiography, or angiography, may be used to confirm arterial damage and identify the extent of injury. Laboratory tests, including hemoglobin levels and coagulation profiles, help evaluate blood loss and clotting function.

Treatment Options

Immediate interventions focus on hemorrhage control, such as direct pressure, tourniquets, or surgical repair. Definitive treatment may include arterial ligation, endovascular repair (e.g., stenting), or bypass grafting. Adjunctive measures include fluid resuscitation, blood transfusion, and pain management. Rehabilitation and physical therapy may be necessary to restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, time to intervention, and presence of complications. Early treatment improves outcomes, but limb loss or long-term disability may occur in severe cases. Follow-up care includes monitoring for infection, vascular complications, and functional recovery. Regular assessments of perfusion and wound healing are essential.

Complications

• Life-threatening hemorrhage or shock.
• Limb ischemia leading to tissue damage or amputation.
• Infection at the injury site or surgical site.
• Vascular complications, such as pseudoaneurysms or arteriovenous fistulas.
• Chronic pain or reduced mobility.

Lifestyle & Prevention

Avoid high-risk activities that increase trauma exposure. Use protective gear during sports or work. Manage vascular health through lifestyle modifications (e.g., smoking cessation, blood pressure control). Follow post-procedure care instructions to reduce iatrogenic injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, limb discoloration, or signs of shock. Prompt evaluation is critical to prevent irreversible damage. Contact a healthcare provider for persistent pain, swelling, or changes in limb function after injury.

Tips for Medical Coders

Document the laterality (left leg) and the nature of the injury (major laceration) to ensure accurate coding. Include details on the encounter type (e.g., initial, subsequent) and any associated complications. Verify that the injury is clearly linked to the femoral artery and not other structures.
