S65.112A Laceration of radial artery at wrist and hand level of left arm, initial encounter

Name of the Condition

• Laceration of radial artery at wrist and hand level of left arm, initial encounter

Summary

A laceration of the radial artery at the wrist and hand level of the left 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. The "initial encounter" designation indicates this is the first episode of care for the injury.

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, check for pulses, and evaluate neurovascular status. Imaging studies, such as Doppler ultrasound or angiography, may be used to confirm vascular injury. Clinical assessment of bleeding, pain, and tissue perfusion is critical to determine the extent of damage.

Treatment Options

Treatment focuses on controlling bleeding, repairing the arterial laceration, and restoring blood flow. This may include direct pressure, surgical repair, or vascular reconstruction. Wound care, pain management, and monitoring for complications are also essential components of care.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timely intervention. With prompt treatment, most patients recover well, but follow-up is necessary to monitor for complications like infection, thrombosis, or nerve damage. Long-term outcomes may include restored function or residual deficits if vascular or nerve injury is significant.

Complications

Potential complications include excessive bleeding, hematoma formation, infection, thrombosis, or permanent nerve damage. Ischemia or tissue loss may occur if blood flow is not restored promptly. Chronic pain or functional impairment is possible in severe cases.

Lifestyle & Prevention

Preventive measures include using safety equipment during activities with hand/wrist trauma risks, avoiding unnecessary exposure to sharp objects, and following proper safety protocols in work or recreational settings. Prompt medical attention for injuries can reduce complication risks.

When to Seek Professional Help

Seek immediate medical care for visible arterial bleeding, severe pain, numbness, or discoloration of the hand/fingers. Persistent swelling, inability to move digits, or signs of infection (e.g., redness, fever) also warrant urgent evaluation.

Tips for Medical Coders

Document the anatomical location (left arm), level (wrist and hand), and encounter type (initial) to support accurate coding. Ensure clinical documentation specifies the injury as a laceration of the radial artery and confirms it is the first encounter for this condition.
