S65.112 Laceration of radial artery at wrist and hand level of left arm

Name of the Condition

• Laceration of radial artery at wrist and hand level of left arm

Summary

A laceration of the radial artery at the wrist and hand level of the left arm involves a cut or tear in the radial artery in this anatomical region, typically resulting from trauma. This condition requires prompt evaluation to assess vascular integrity and potential complications, as the radial artery is a critical blood vessel supplying the hand and fingers.

Causes

Direct trauma to the wrist or hand, such as lacerations, puncture wounds, or crush injuries. Penetrating injuries from sharp objects like glass, knives, or tools. Blunt force trauma causing vessel compression or disruption. Iatrogenic injury during surgical procedures involving the wrist or hand.

Risk Factors

• Participation in activities with a risk of hand or wrist trauma (e.g., sports, manual labor).
• Use of sharp objects or tools without proper safety precautions.
• Preexisting vascular conditions that may weaken vessel integrity.
• Advanced age, which may be associated with reduced tissue resilience.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the wrist or hand.
• Weak or absent pulses in the affected digits.
• Coolness, pallor, or discoloration of the hand or fingers.
• Numbness or tingling in the radial nerve distribution (e.g., thumb, index finger).

Diagnosis

Diagnosis involves a thorough physical examination to assess the injury site, pulses, and neurovascular status. Imaging studies, such as Doppler ultrasound or angiography, may be used to evaluate arterial flow and identify the extent of the laceration. Clinical assessment of symptoms like pain, swelling, and discoloration also aids in diagnosis.

Treatment Options

Treatment focuses on controlling bleeding, restoring arterial flow, and preventing complications. This may include direct pressure, surgical repair of the artery, or vascular reconstruction. Wound care and monitoring for infection or ischemia are also essential. In some cases, anticoagulation or antiplatelet therapy may be considered to prevent thrombosis.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, timely intervention, and absence of complications. Early treatment generally leads to favorable outcomes, but delayed care may result in tissue damage or functional impairment. Follow-up appointments are necessary to monitor healing, assess circulation, and address any residual symptoms or complications.

Complications

Potential complications include arterial thrombosis, ischemia of the hand or fingers, infection, nerve damage, or chronic pain. In severe cases, amputation may be required if blood flow is not restored promptly. Long-term issues like reduced mobility or sensory deficits may also occur.

Lifestyle & Prevention

Preventive measures include using safety equipment during activities with hand/wrist trauma risks, avoiding unnecessary exposure to sharp objects, and maintaining vascular health. Prompt medical attention for injuries to the wrist or hand can reduce complication risks. Avoiding smoking and managing conditions like diabetes may support vascular integrity.

When to Seek Professional Help

Seek immediate medical care for visible bleeding, severe pain, or signs of poor circulation (e.g., coolness, discoloration) after a wrist or hand injury. Delayed evaluation may worsen outcomes, so urgent assessment is recommended for suspected arterial lacerations.

Tips for Medical Coders

Document the specific anatomical location (wrist and hand level of left arm) and confirm the injury is a laceration of the radial artery. Ensure the left arm laterality is clearly specified in the medical record. For accurate coding, verify that the documentation supports the diagnosis and excludes other arterial injuries or unrelated conditions.
