S65.111 Laceration of radial artery at wrist and hand level of right arm

Name of the Condition

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

Summary

A laceration of the radial artery at the wrist and hand level of the right arm involves a cut or tear to the radial artery in this anatomical region, typically resulting from trauma. This condition requires evaluation to assess vascular injury and determine appropriate management, 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 needed to restore blood flow.
• Antibiotics to prevent infection in open wounds.
• Pain management and wound care.

Prognosis and Follow-Up

Prognosis depends on the severity of the laceration and timely intervention. Early treatment reduces risk of complications like ischemia or infection. Follow-up may include monitoring for vascular integrity, wound healing, and functional recovery of the hand.

Complications

• Ischemia or tissue necrosis due to reduced blood flow.
• Infection of the wound or vascular graft.
• Nerve damage affecting hand sensation or movement.
• Chronic pain or vascular insufficiency.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Handle sharp objects with care and follow safety protocols.
• Maintain awareness of hand/wrist positioning to avoid trauma.
• Seek prompt medical attention for injuries to prevent complications.

When to Seek Professional Help

Seek immediate care for severe bleeding, loss of pulse, or signs of ischemia (coolness, pallor, numbness). Consult a healthcare provider for persistent pain, swelling, or wound concerns after injury.

Tips for Medical Coders

Document the specific location (wrist and hand level) and laterality (right arm) to support code assignment. Include details on the nature of the injury (laceration) and any associated complications for accurate coding. Ensure clinical documentation aligns with the anatomical specificity of the code.
