S15.121 Major laceration of right vertebral artery

Name of the Condition

• Major laceration of right vertebral artery

Summary

A major laceration of the right vertebral artery involves a significant tear or cut in the right vertebral artery, a blood vessel that supplies blood to the brainstem and cerebellum. This condition may result from trauma or iatrogenic causes and requires prompt evaluation to address potential complications such as hemorrhage, ischemia, or neurological deficits.

Causes

Traumatic events, including motor vehicle collisions, falls, or penetrating injuries to the neck, are common causes. Blunt force trauma or hyperextension of the neck may also damage the vertebral artery. Iatrogenic injuries during surgical or interventional procedures, such as cervical spine surgery or angiography, can occur.

Risk Factors

• High-velocity trauma or significant force to the cervical spine.
• Penetrating injuries involving the neck region.
• Preexisting vascular conditions (e.g., atherosclerosis) that weaken vessel walls.
• Advanced age or comorbidities affecting tissue integrity.

Symptoms

• Neck pain or tenderness at the injury site.
• Swelling, hematoma, or ecchymosis in the cervical region.
• Neurological symptoms like dizziness, vertigo, or ataxia, indicating potential brainstem or cerebellar ischemia.
• Signs of hemorrhage, including rapid pulse, low blood pressure, or shock.
• Possible stroke-like symptoms if blood flow to the brain is compromised.

Diagnosis

Physical examination to assess for signs of trauma or vascular compromise. Imaging studies, such as CT angiography or ultrasound, to evaluate the extent of the laceration and rule out complications. Additional tests may include angiography to confirm the injury and assess blood flow.

Treatment Options

Treatment depends on the severity and stability of the patient. Options may include observation for stable cases, endovascular repair (e.g., stenting or embolization), or surgical intervention to repair the laceration. Hemodynamic support and monitoring for neurological changes are critical.

Prognosis and Follow-Up

Prognosis varies based on the extent of injury, promptness of treatment, and presence of complications. Close follow-up is necessary to monitor for recurrent symptoms, healing progress, or delayed complications. Neurological assessments and imaging may be repeated as needed.

Complications

• Hemorrhage or hematoma formation.
• Ischemia or stroke due to reduced blood flow.
• Neurological deficits (e.g., dizziness, weakness, or vision changes).
• Vascular occlusion or pseudoaneurysm development.

Lifestyle & Prevention

Avoid high-risk activities that may cause neck trauma. Use protective gear during sports or occupations with neck injury risks. Follow post-procedure care instructions after cervical spine interventions to reduce iatrogenic injury risk.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe neck pain, neurological symptoms (e.g., dizziness, weakness), or signs of hemorrhage (e.g., rapid heart rate, low blood pressure). Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

Document the laterality (right) and the nature of the injury (major laceration) to accurately assign this code. Ensure clinical documentation supports the severity and anatomical location. Review imaging or procedural notes for confirmation of the injury type.
