S75.02 Major laceration of femoral artery

Name of the Condition

• Major laceration of femoral artery

Summary

A major laceration of the femoral artery 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 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.
• Weak or absent pulses distal to the injury (e.g., in the lower leg).
• Coolness, pallor, or numbness in the affected limb.
• Signs of shock (e.g., rapid heart rate, low blood pressure) in severe cases.

Diagnosis

Physical examination to assess for bleeding, pulses, and limb perfusion. Imaging studies, such as Doppler ultrasound, CT angiography, or angiography, to evaluate arterial damage and blood flow. Laboratory tests to assess hemoglobin levels and coagulation status.

Treatment Options

Immediate hemorrhage control through direct pressure, tourniquets, or surgical intervention. Vascular repair, including suturing, grafting, or bypass, to restore arterial integrity. Monitoring for complications such as compartment syndrome or infection. Supportive care, including fluid resuscitation and pain management.

Prognosis and Follow-Up

Prognosis depends on the extent of injury, timeliness of treatment, and presence of complications. Recovery may involve rehabilitation to restore limb function. Follow-up imaging or vascular assessments may be needed to monitor for long-term complications, such as stenosis or aneurysm formation.

Complications

Hemorrhagic shock due to uncontrolled bleeding. Ischemia or tissue necrosis from reduced blood flow. Compartment syndrome from swelling. Infection at the injury site. Long-term vascular complications, such as aneurysm or stenosis.

Lifestyle & Prevention

Avoid high-risk activities that increase the likelihood of severe trauma. Use protective gear during sports or hazardous work. Manage preexisting vascular conditions to reduce fragility. Follow post-procedure care instructions after femoral artery interventions to minimize iatrogenic injury.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, loss of pulse in the limb, or signs of shock. Consult a healthcare provider for persistent pain, swelling, or changes in limb color after trauma. Follow up with a specialist if symptoms of vascular compromise develop.

Tips for Medical Coders

Document the extent of the laceration (e.g., partial vs. complete) and associated complications. Specify if the injury is open or closed, and note any surgical interventions. Ensure documentation supports the severity of the laceration to justify the code. Include details about trauma mechanism or iatrogenic causes when applicable.
