S15.121A Major laceration of right vertebral artery, initial encounter

Name of the Condition

• Major laceration of right vertebral artery, initial encounter

Summary

A major laceration of the right vertebral artery is a significant tear in the blood vessel that supplies blood to the brainstem and cerebellum. This condition typically results from trauma or iatrogenic causes and requires prompt evaluation to prevent 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

• Severe neck pain or tenderness at the injury site.
• Significant 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. Angiography may be used to confirm the diagnosis and guide treatment.

Treatment Options

• Immediate medical intervention to control bleeding and stabilize the patient.
• Surgical repair or endovascular procedures to address the laceration.
• Monitoring for neurological changes and managing complications as needed.
• Supportive care, including pain management and observation.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and promptness of treatment. Early intervention improves outcomes, but complications such as stroke or permanent neurological damage may occur. Follow-up imaging and neurological assessments are typically recommended to monitor recovery.

Complications

• Hemorrhage or hematoma formation.
• Ischemia or stroke due to reduced blood flow.
• Permanent neurological deficits.
• Infection or other procedural complications.

Lifestyle & Prevention

• Use protective measures during high-risk activities (e.g., seatbelts, helmets).
• Avoid neck manipulation or trauma in vulnerable individuals.
• Manage preexisting vascular conditions to reduce 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 after trauma or a procedure.

Tips for Medical Coders

Document the laterality (right), severity (major laceration), and encounter type (initial) to accurately assign this code. Ensure clinical documentation supports the diagnosis and any associated procedures or complications.
