S55.111 Laceration of radial artery at forearm level, right arm

Name of the Condition

• Laceration of radial artery at forearm level, right arm

Summary

A laceration of the radial artery at the forearm level, right arm, involves a cut or tear in the radial artery within the forearm region of the right arm. This injury may disrupt blood flow to the hand and fingers, depending on the severity of the arterial damage. The condition typically results from trauma and may be associated with other tissue injuries.

Causes

Direct trauma to the forearm, such as lacerations from sharp objects, blunt force injuries, or penetrating wounds. Fractures of the forearm bones (radius or ulna) may also damage the radial artery. Iatrogenic injuries during surgical procedures or medical interventions in the forearm area.

Risk Factors

• Participation in activities with a high risk of forearm trauma (e.g., contact sports, manual labor).
• Use of sharp tools or machinery without proper safety precautions.
• Preexisting vascular conditions that may weaken arterial walls.
• Proximity to the radial artery during surgical or interventional procedures.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the forearm.
• Weak or absent pulse in the wrist or hand (if arterial flow is compromised).
• Numbness, tingling, or coldness in the fingers (due to reduced blood flow).
• Pale or bluish discoloration of the hand or fingers.

Diagnosis

Physical examination to assess pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate vascular integrity and blood flow. Imaging studies (e.g., X-rays) to identify associated fractures or soft tissue damage.

Treatment Options

• Direct pressure to control bleeding.
• Surgical repair or ligation of the radial artery.
• Revascularization procedures if blood flow is severely compromised.
• Pain management and wound care.
• Monitoring for complications such as infection or ischemia.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Most cases resolve with appropriate treatment, but delayed care may lead to complications. Follow-up may include monitoring for signs of infection, assessing circulation, and evaluating functional recovery.

Complications

• Persistent bleeding or hematoma formation.
• Ischemia or tissue damage due to reduced blood flow.
• Infection at the injury site.
• Nerve injury or chronic pain.
• Long-term vascular complications, such as aneurysm or stenosis.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Follow safety protocols when handling sharp objects or machinery.
• Maintain awareness of forearm anatomy during medical procedures.
• Seek prompt medical attention for forearm injuries to prevent complications.

When to Seek Professional Help

• Visible arterial bleeding that does not stop with pressure.
• Weak or absent pulse in the wrist or hand.
• Numbness, tingling, or coldness in the fingers.
• Severe pain, swelling, or discoloration of the hand or forearm.
• Signs of infection, such as redness, warmth, or pus.

Tips for Medical Coders

Document the specific location (forearm level, right arm) and nature of the injury (laceration) to support accurate coding. Include details about the mechanism of injury, associated complications, and any interventions performed. Ensure documentation aligns with the clinical findings to justify the code selection.
