S75.0 Injury of femoral artery

Name of the Condition

• Injury of femoral artery

Summary

An injury of the femoral artery refers to damage to the femoral artery, a major blood vessel in the thigh, typically resulting from trauma. This condition may involve partial or complete disruption of the arterial wall, leading to bleeding, reduced blood flow, or other vascular complications. Prompt evaluation and management are essential to prevent serious outcomes.

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, falls). Iatrogenic causes, including complications from medical procedures involving the femoral artery (e.g., catheterization). 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 thigh trauma (e.g., contact sports, combat).
• Proximity to penetrating injuries or blunt force events.
• Preexisting vascular conditions that may weaken the artery (e.g., atherosclerosis, aneurysms).
• Advanced age, which may increase susceptibility to injury or vascular fragility.

Symptoms

• Visible bleeding or hematoma in the thigh or groin area.
• 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 integrity and identify injuries. Laboratory tests to assess for blood loss or coagulation abnormalities.

Treatment Options

• Immediate control of bleeding (e.g., direct pressure, tourniquet) in emergency settings.
• Surgical repair or reconstruction of the artery (e.g., suturing, grafting).
• Endovascular interventions (e.g., angioplasty, stenting) for selected cases.
• Monitoring for complications like compartment syndrome or infection.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, time to treatment, and presence of complications. Early intervention improves outcomes, but delayed care may lead to limb loss or long-term disability. Follow-up includes monitoring for vascular function, wound healing, and rehabilitation to restore mobility.

Complications

• Hemorrhagic shock from uncontrolled bleeding.
• Ischemia or tissue necrosis due to reduced blood flow.
• Compartment syndrome in the affected limb.
• Infection at the injury site or post-surgical complications.
• Long-term vascular sequelae, such as aneurysm formation or chronic pain.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, work).
• Avoid unnecessary trauma to the thigh or groin area.
• Manage underlying vascular conditions to reduce fragility.
• Seek prompt medical care for suspected injuries to minimize damage.

When to Seek Professional Help

• Visible bleeding or swelling in the thigh or groin.
• Weak or absent pulses in the leg.
• Signs of shock (e.g., dizziness, rapid breathing).
• Numbness, coolness, or discoloration of the affected limb.
• Persistent pain or difficulty moving the leg.

Tips for Medical Coders

Document the mechanism of injury (e.g., penetrating, blunt) and any associated complications (e.g., hemorrhage, ischemia) to support code assignment. Include details on diagnostic methods (e.g., imaging, physical exam) and treatment interventions (e.g., surgery, endovascular repair) for accurate coding. Ensure specificity regarding the artery involved and the nature of the injury (e.g., laceration, transection) to align with documentation.
