S45.011 Laceration of axillary artery, right side

Name of the Condition

• Laceration of axillary artery, right side

Summary

This condition involves a tear or cut in the axillary artery, a major blood vessel in the right armpit region. The injury may result from trauma and can affect blood flow to the right upper limb, potentially leading to complications if not addressed promptly.

Causes

Common causes include penetrating or blunt trauma, such as stab wounds, gunshot injuries, fractures, or dislocations of the shoulder or upper arm. Surgical procedures in the area may also lead to accidental injury.

Risk Factors

• Engaging in high-risk activities with potential for trauma, such as contact sports or motor vehicle accidents. Pre-existing vascular conditions or anatomical variations may increase susceptibility.

Symptoms

• Symptoms may include severe pain, swelling, bruising, or a visible wound in the right armpit. Reduced or absent pulse in the right arm, coldness, paleness, or weakness of the hand or arm may indicate compromised blood flow.

Diagnosis

Diagnosis typically involves a physical examination to assess pulse, sensation, and movement. Imaging tests like Doppler ultrasound, CT angiography, or MR angiography may be used to evaluate the artery and detect damage.

Treatment Options

• Treatment may include surgical repair to restore blood flow, use of anticoagulants or antiplatelet medications to prevent clots, and monitoring for complications. Physical therapy may aid in recovery of function.

Prognosis and Follow-Up

Prognosis depends on the extent of the injury and timely treatment. Follow-up care may involve regular monitoring of blood flow, imaging studies, and rehabilitation to restore strength and mobility.

Complications

• Complications may include excessive bleeding, formation of blood clots, infection, or permanent damage to the arm due to reduced blood supply. Nerve injury or limb ischemia are also possible.

Lifestyle & Prevention

• Avoid high-risk activities that may lead to trauma. Use protective gear during sports or work involving potential injury. Maintain vascular health through regular exercise and a balanced diet.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible bleeding, or signs of reduced blood flow (e.g., coldness, paleness, or weakness) in the right arm after an injury.

Tips for Medical Coders

• Document the specific location (right side) and nature of the injury (laceration) to support accurate coding. Include details of trauma mechanism, clinical findings, and imaging results to confirm the diagnosis. Ensure documentation aligns with the specificity of the code S45.011.
