S45.012 Laceration of axillary artery, left side

Name of the Condition

• Laceration of axillary artery, left side

Summary

This condition involves a tear or cut in the axillary artery, a major blood vessel in the left armpit region. The laceration may disrupt blood flow to the left upper limb and requires prompt medical attention to prevent complications.

Causes

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

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 left armpit. Reduced or absent pulse in the left 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.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Follow-up care may involve monitoring for signs of infection, assessing limb function, and managing any long-term vascular issues.

Complications

Potential complications include excessive bleeding, formation of blood clots, nerve damage, infection, or permanent loss of limb function if blood flow is not restored promptly.

Lifestyle & Prevention

• Avoid high-risk activities that may lead to trauma. Use protective gear during sports or work involving potential injury. Maintain overall 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 left arm or hand.

Tips for Medical Coders

Document the specific side (left) and confirm the presence of a laceration. Ensure clinical documentation supports the diagnosis and any associated trauma or procedures. Code S45.012 is specific to the left side and should be used when the injury is clearly documented as such.
