S25.121 Major laceration of right innominate or subclavian artery

Name of the Condition

• Major laceration of right innominate or subclavian artery

Summary

This condition describes a severe cut or tear in the right innominate or subclavian artery, which are major blood vessels supplying the upper body. Such injuries typically result from trauma and require urgent medical intervention to prevent life-threatening complications like hemorrhage or ischemia.

Causes

Major lacerations of the right innominate or subclavian artery are usually caused by traumatic events, such as penetrating injuries (e.g., stab or gunshot wounds), blunt force trauma, or motor vehicle accidents. Iatrogenic injury during surgical or interventional procedures may also occur.

Risk Factors

• High-risk occupations or activities (e.g., construction, contact sports).
• History of trauma or violence.
• Motor vehicle accidents.
• Proximity to penetrating or blunt force trauma.

Symptoms

• Severe bleeding (external or internal).
• Rapid heart rate and weak pulse.
• Pallor, cold, clammy skin.
• Dizziness or loss of consciousness.
• Swelling or bruising in the neck or shoulder area.
• Weak or absent pulses in the right arm.

Diagnosis

Diagnosis involves a physical examination to assess for signs of trauma or vascular compromise. Imaging studies, such as CT angiography or Doppler ultrasound, are used to visualize the artery and determine the extent of the laceration. Laboratory tests may evaluate blood loss or coagulation status.

Treatment Options

• Emergency surgical repair to restore arterial integrity and blood flow.
• Blood transfusions to address hemorrhagic shock.
• Medications for pain management, infection prevention, or anticoagulation (if indicated).
• Endovascular techniques (e.g., stenting) in select cases.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, time to intervention, and presence of complications. Close monitoring for recurrent bleeding, infection, or vascular complications is essential. Long-term follow-up may include imaging to assess vessel patency and functional recovery.

Complications

• Hemorrhagic shock.
• Ischemia or infarction of the upper limb or brain.
• Infection (e.g., sepsis).
• Vascular thrombosis or pseudoaneurysm formation.
• Chronic pain or disability.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Follow safety protocols in occupational settings.
• Avoid unnecessary trauma to the neck or chest region.
• Prompt medical evaluation after trauma to the upper torso.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, dizziness, loss of consciousness, or signs of shock (e.g., pale skin, rapid pulse) following trauma to the neck or chest.

Tips for Medical Coders

Document the specific vessel (right innominate or subclavian artery) and the nature of the injury (major laceration) to support accurate coding. Include details on the encounter type (e.g., initial, subsequent) and any associated complications to ensure comprehensive coding.
