S65.119 Laceration of radial artery at wrist and hand level of unspecified arm

Name of the Condition

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

Summary

A laceration of the radial artery at the wrist and hand level of the unspecified 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 physical examination to assess the injury site, evaluate pulses, and check for signs of ischemia. Imaging studies, such as Doppler ultrasound or angiography, may be used to confirm vascular damage. Clinical assessment of neurovascular status is critical to determine the extent of injury.

Treatment Options

Treatment focuses on controlling bleeding, restoring vascular flow, and preventing complications. This may include direct pressure, surgical repair of the artery, or revascularization procedures. Wound care and monitoring for infection or ischemia are also essential.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Early intervention improves outcomes, while delayed care may lead to tissue damage or functional impairment. Follow-up includes monitoring for complications like infection, thrombosis, or nerve injury.

Complications

Potential complications include excessive bleeding, hematoma formation, infection, thrombosis, or permanent nerve or tissue damage. Ischemia of the hand or fingers may occur if blood flow is not restored promptly.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, handling sharp objects with care, and following safety protocols in work or recreational settings. Prompt medical attention for wrist or hand injuries is advised.

When to Seek Professional Help

Seek immediate medical care for visible bleeding, severe pain, or signs of impaired circulation (e.g., coolness, discoloration) in the hand or fingers. Delayed evaluation may increase the risk of complications.

Tips for Medical Coders

Document the anatomical location (wrist and hand level) and the unspecified arm status clearly. Ensure the injury is confirmed as a laceration of the radial artery, with details on trauma mechanism and clinical findings to support coding accuracy.
