S75.021 Major laceration of femoral artery, right leg

Name of the Condition

• Major laceration of femoral artery, right leg

Summary

A major laceration of the femoral artery in the right 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, reduced blood flow, or vascular compromise. Prompt evaluation and intervention are critical to prevent life-threatening complications such as hemorrhage, ischemia, or limb loss.

Causes

Direct trauma to the right thigh, such as penetrating injuries (e.g., stab wounds, gunshot wounds) or blunt force trauma (e.g., motor vehicle accidents, falls). Iatrogenic injury during medical procedures involving the femoral artery, such as catheterization or 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 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.
• Use of anticoagulant or antiplatelet medications, which can exacerbate bleeding.

Symptoms

• Visible, profuse bleeding or large hematoma in the right 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 viability. Imaging studies, such as Doppler ultrasound, CT angiography, or angiography, to evaluate arterial damage and blood flow. Laboratory tests to check for anemia or coagulation abnormalities.

Treatment Options

• Immediate hemorrhage control through direct pressure, tourniquets, or surgical intervention.
• Surgical repair of the arterial laceration, such as suturing or grafting.
• Endovascular procedures, like angioplasty or stenting, in select cases.
• Blood transfusion or fluid resuscitation to manage shock.
• Antibiotics to prevent infection, especially with open wounds.

Prognosis and Follow-Up

Prognosis depends on the extent of injury, timeliness of treatment, and presence of complications. Early intervention improves outcomes, but severe cases may result in limb loss or long-term vascular issues. Follow-up includes monitoring for infection, assessing limb function, and evaluating for recurrent bleeding or ischemia.

Complications

• Hemorrhagic shock due to uncontrolled bleeding.
• Acute limb ischemia leading to tissue damage or amputation.
• Infection at the injury site or surgical site.
• Vascular complications, such as pseudoaneurysm or arteriovenous fistula.
• Chronic pain or functional impairment in the affected limb.

Lifestyle & Prevention

• Avoid high-risk activities that may cause thigh trauma.
• Use protective gear during sports or hazardous work.
• Manage vascular conditions (e.g., atherosclerosis) with medical care.
• Follow post-procedure instructions carefully to reduce iatrogenic injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, limb coolness, pallor, or numbness, or signs of shock (e.g., dizziness, rapid heartbeat). Delayed care increases the risk of complications.

Tips for Medical Coders

Document the location (right leg), severity (major laceration), and any associated injuries or procedures. Ensure clinical notes specify the extent of arterial damage and treatment provided to support code assignment.
