S45.001 Unspecified injury of axillary artery, right side

Name of the Condition

• Unspecified injury of axillary artery, right side

Summary

This condition involves damage to 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.

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

The prognosis depends on the severity of the injury and timeliness of treatment. Follow-up care may involve monitoring for complications, repeat imaging, and rehabilitation to restore strength and mobility.

Complications

• Complications can include limb ischemia, nerve damage, infection, or chronic pain. Untreated injuries may lead to permanent disability or amputation.

Lifestyle & Prevention

• Avoid high-risk activities that increase trauma exposure. 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) in the right arm or hand.

Tips for Medical Coders

• Code S45.001 is used for unspecified injury of the axillary artery on the right side. Documentation should specify the side and nature of the injury (e.g., blunt vs. penetrating) when available. Ensure the injury is clearly linked to the axillary artery and not other structures.
