S65.11 Laceration of radial artery at wrist and hand level

Name of the Condition

• Laceration of radial artery at wrist and hand level

Summary

A laceration of the radial artery at the wrist and hand level 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

Physical examination to assess for vascular compromise, including pulse palpation and capillary refill. Doppler ultrasound or angiography to evaluate arterial flow and identify laceration extent. Imaging studies (e.g., X-ray) to rule out associated fractures or soft tissue damage.

Treatment Options

• Direct pressure to control bleeding.
• Surgical repair or ligation of the lacerated artery.
• Vascular reconstruction if feasible.
• Antibiotics to prevent infection.
• Pain management and wound care.

Prognosis and Follow-Up

Prognosis depends on the extent of vascular damage and timely intervention. Complications like ischemia or infection may affect recovery. Follow-up includes monitoring for vascular function, wound healing, and signs of complications.

Complications

• Ischemia or tissue necrosis due to reduced blood flow.
• Infection at the injury site.
• Nerve damage (e.g., radial nerve injury).
• Chronic pain or functional impairment.
• Vascular insufficiency in the hand or fingers.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Handle sharp objects with care.
• Maintain vascular health through regular exercise and a balanced diet.
• Seek prompt medical attention for wrist or hand injuries.

When to Seek Professional Help

• Uncontrolled bleeding or severe pain.
• Weak or absent pulses in the hand or fingers.
• Coolness, pallor, or discoloration of the affected digits.
• Numbness, tingling, or weakness in the hand or fingers.
• Signs of infection (e.g., redness, swelling, fever).

Tips for Medical Coders

Document the anatomical location (wrist and hand level) and the nature of the injury (laceration). Include details on the mechanism of injury, associated complications, and any surgical interventions. Ensure specificity in clinical notes to support accurate coding.
