S85.011 Laceration of popliteal artery, right leg

Name of the Condition

• Laceration of popliteal artery, right leg

Summary

A laceration of the popliteal artery in the right leg involves a cut or tear to the blood vessel located behind the right knee, typically resulting from trauma. This injury may disrupt blood flow, requiring prompt evaluation to prevent complications such as ischemia or limb loss.

Causes

Direct trauma to the right knee region, such as from blunt force, penetrating injuries, or fractures. Motor vehicle accidents, falls, or sports-related injuries are common mechanisms. Iatrogenic injury during surgical procedures near the right popliteal fossa may also occur.

Risk Factors

• High-impact activities or occupations with right knee exposure to injury.
• Preexisting vascular conditions that weaken arterial walls.
• Advanced age, which may reduce tissue elasticity.
• Use of anticoagulant medications increasing bleeding risk.

Symptoms

• Sudden pain or swelling behind the right knee.
• Weak or absent pulses in the right lower leg.
• Coolness, pallor, or numbness in the right foot or toes.
• Visible bruising or hematoma in the right popliteal area.
• Difficulty bearing weight or moving the right knee.

Diagnosis

Physical examination to assess pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate blood flow and identify vessel damage. CT angiography or MRI may be used to assess associated injuries.

Treatment Options

Surgical repair or revascularization to restore blood flow. Endovascular techniques, such as stenting or angioplasty, may be considered in select cases. Anticoagulation or antiplatelet therapy to prevent clot formation. Pain management and wound care as needed.

Prognosis and Follow-Up

Prognosis depends on the extent of injury and timeliness of treatment. Regular follow-up to monitor vascular function and detect complications. Long-term monitoring for signs of ischemia or reocclusion.

Complications

Ischemia or tissue necrosis due to reduced blood flow. Hemorrhage or hematoma formation. Infection at the injury site. Chronic pain or functional impairment. Potential for amputation in severe cases.

Lifestyle & Prevention

Avoid high-risk activities that may lead to knee trauma. Use protective equipment during sports or work. Maintain vascular health through regular exercise and a balanced diet. Follow post-injury rehabilitation guidelines.

When to Seek Professional Help

Persistent pain, swelling, or bruising behind the right knee. Weak or absent pulses in the right foot or toes. Numbness, tingling, or coldness in the right leg. Signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the specific location (right leg) and nature of the injury (laceration) to support accurate coding. Include details of trauma mechanism, diagnostic findings, and treatment provided. Ensure documentation aligns with clinical guidelines for popliteal artery injuries.
