S55.191 Other specified injury of radial artery at forearm level, right arm

Name of the Condition

• Other specified injury of radial artery at forearm level, right arm

Summary

An injury of the radial artery at the forearm level, right arm, involves damage to the radial artery within the forearm region of the right arm. This may result from trauma, such as lacerations, contusions, or penetrating injuries, and can affect blood flow to the hand and fingers. The severity of the injury depends on the extent of arterial damage and associated tissue involvement.

Causes

Direct trauma to the forearm, including 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 or hemostatic agents to control bleeding.
• Surgical repair or ligation of the injured artery, depending on the extent of damage.
• Revascularization procedures (e.g., bypass grafts) if blood flow is severely compromised.
• Pain management and wound care for associated injuries.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timely intervention. Early treatment can restore blood flow and prevent complications. Follow-up may include monitoring for signs of ischemia, infection, or re-injury. Long-term outcomes may involve functional recovery of the affected limb.

Complications

• Ischemia or tissue necrosis due to reduced blood flow.
• Infection at the injury site.
• Chronic pain or vascular insufficiency.
• Nerve damage from associated trauma.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Follow safety protocols when handling sharp tools or machinery.
• Maintain vascular health through regular exercise and a balanced diet.
• Avoid unnecessary trauma to the forearm region.

When to Seek Professional Help

Seek immediate medical attention if there is uncontrolled bleeding, severe pain, numbness, or discoloration of the hand or fingers. Prompt evaluation is critical to prevent permanent tissue damage.

Tips for Medical Coders

Document the specific type of injury (e.g., laceration, contusion) and the anatomical location (forearm level, right arm). Include details about the mechanism of injury, associated fractures, or surgical interventions. Ensure the code S55.191 is used when the injury is specified as "other" and involves the right arm.
