S85.149 Laceration of anterior tibial artery, unspecified leg

Name of the Condition

• Laceration of anterior tibial artery, unspecified leg

Summary

A laceration of the anterior tibial artery in the unspecified leg involves a cut or tear to this major blood vessel, which can disrupt blood flow to the foot and lower leg. Prompt evaluation is necessary to assess vascular integrity and prevent complications such as ischemia or limb loss.

Causes

Direct trauma to the lower leg, such as from blunt force, penetrating injuries, or fractures. Surgical procedures or medical interventions in the lower leg area. Accidental or intentional injuries that disrupt vascular integrity.

Risk Factors

• Participation in high-impact activities or contact sports.
• History of lower leg fractures or vascular disease.
• Use of anticoagulant medications that increase bleeding risk.
• Advanced age or conditions affecting tissue integrity.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the lower leg.
• Changes in skin color (e.g., pallor or cyanosis) due to reduced blood flow.
• Weak or absent pulses in the affected limb.
• Numbness, tingling, or coldness in the foot or toes.

Diagnosis

Physical examination to assess pulses, skin color, and signs of ischemia. Doppler ultrasound or angiography to evaluate blood flow and identify vascular damage. Imaging studies (e.g., CT angiography) if fractures or internal injuries are suspected.

Treatment Options

• Immediate vascular repair or revascularization to restore blood flow.
• Surgical intervention to repair the lacerated artery.
• Anticoagulant therapy to prevent clot formation, if indicated.
• Monitoring for complications such as compartment syndrome.

Prognosis and Follow-Up

Prognosis depends on the extent of vascular damage and timely intervention. Follow-up includes monitoring for signs of ischemia, wound healing, and functional recovery. Long-term outcomes may involve rehabilitation to restore mobility.

Complications

• Ischemia or tissue necrosis due to reduced blood flow.
• Compartment syndrome from swelling and pressure.
• Infection at the injury site.
• Chronic pain or vascular insufficiency.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid unnecessary trauma to the lower leg.
• Manage underlying conditions like diabetes or vascular disease.
• Follow post-injury care instructions to promote healing.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, loss of pulse, or signs of ischemia (e.g., coldness, numbness). Prompt evaluation is critical to prevent permanent damage.

Tips for Medical Coders

Document the specific leg (right/left) if known, as this impacts coding specificity. Include details on the mechanism of injury, vascular assessment, and any interventions performed. Ensure documentation supports the diagnosis and aligns with clinical findings.
