S25.111 Minor laceration of right innominate or subclavian artery

Name of the Condition

• Minor laceration of right innominate or subclavian artery

Summary

This condition involves a minor laceration (cut) of the right innominate or subclavian artery, which are major blood vessels supplying the upper body and arm. Such injuries can disrupt blood flow and may result from trauma or other medical events. The severity and specific vessel affected influence clinical presentation and management.

Causes

Injuries to the right innominate or subclavian artery are typically caused by traumatic events, such as motor vehicle accidents, penetrating wounds (e.g., stab or gunshot injuries), or blunt force trauma to the chest or neck. Medical procedures involving these areas may also lead to vascular injury.

Risk Factors

• High-risk occupations or activities (e.g., construction, contact sports).
• History of trauma or violence.
• Undergoing neck or thoracic surgeries.
• Age-related factors, such as increased susceptibility to falls in older adults.

Symptoms

• Mild to moderate bleeding.
• Pain or tenderness in the neck, chest, or shoulder area.
• Swelling or bruising in the affected region.
• Weak or diminished pulse in the arm.
• Dizziness or lightheadedness.

Diagnosis

Diagnosis involves a physical examination to assess for signs of trauma or vascular compromise. Imaging studies, such as CT angiography or ultrasound, are used to visualize the affected artery and assess the extent of the injury. Doppler ultrasound may evaluate blood flow.

Treatment Options

Treatment depends on the severity of the laceration and the patient’s overall condition. Minor injuries may be managed with observation and supportive care, while more significant lacerations may require surgical repair or endovascular intervention to restore blood flow.

Prognosis and Follow-Up

Prognosis is generally favorable for minor lacerations, especially with prompt diagnosis and appropriate treatment. Follow-up care may include monitoring for complications, such as infection or rebleeding, and imaging to ensure the artery heals properly.

Complications

• Infection at the injury site.
• Persistent bleeding or hematoma formation.
• Vascular compromise leading to tissue damage in the arm or upper body.
• Long-term vascular issues, such as aneurysm or stenosis.

Lifestyle & Prevention

• Avoid high-risk activities that increase the likelihood of trauma.
• Use protective gear during contact sports or hazardous work.
• Follow post-procedure care instructions after neck or thoracic surgeries to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe bleeding, dizziness, fainting, or signs of shock (e.g., pale skin, rapid heartbeat). Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

Document the specific vessel (right innominate or subclavian artery) and the nature of the injury (minor laceration) to support accurate coding. Include details about the mechanism of injury, clinical findings, and any imaging or procedures performed to confirm the diagnosis.
