S65.011 Laceration of ulnar artery at wrist and hand level of right arm

Name of the Condition

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

Summary

A laceration of the ulnar artery at the wrist and hand level of the right arm involves a cut or tear to the ulnar artery in this specific anatomical region. This type of vascular injury can disrupt blood flow to the hand and fingers, requiring prompt evaluation to assess the extent of damage and determine appropriate management. The ulnar artery is a critical vessel supplying the medial aspect of the hand, and its laceration may lead to complications if not addressed.

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 ulnar nerve distribution (e.g., little finger, ring 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 the extent of injury. Imaging studies (e.g., X-rays) to rule out associated fractures or soft tissue damage.

Treatment Options

• Direct pressure to control bleeding and stabilize the patient.
• Surgical repair or ligation of the lacerated artery, depending on the extent of injury.
• Revascularization procedures to restore blood flow if ischemia is present.
• Antibiotics or tetanus prophylaxis if the wound is contaminated.
• Pain management and wound care to promote healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, time to treatment, and presence of complications. Early intervention improves outcomes by preserving vascular function. Follow-up may include monitoring for signs of infection, ischemia, or nerve damage. Rehabilitation may be necessary to restore mobility and strength.

Complications

• Persistent bleeding or hematoma formation.
• Ischemia or tissue necrosis due to inadequate blood flow.
• Nerve injury (e.g., ulnar nerve dysfunction) from trauma or swelling.
• Infection at the injury site.
• Long-term vascular insufficiency or chronic pain.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., gloves for manual labor).
• Avoid handling sharp objects carelessly.
• Maintain good vascular health through regular exercise and a balanced diet.
• Seek prompt medical attention for wrist or hand injuries to prevent complications.

When to Seek Professional Help

• Visible severe bleeding that does not stop with pressure.
• Signs of ischemia (e.g., coolness, pallor, or numbness in the hand/fingers).
• Intense pain, swelling, or inability to move the wrist or fingers.
• Suspected infection (e.g., redness, warmth, or pus at the injury site).

Tips for Medical Coders

Document the specific location (wrist and hand level of right arm) and nature of the injury (laceration) to support accurate coding. Include details about the mechanism of injury, clinical findings, and treatment provided. Ensure the code aligns with the anatomical specificity and laterality (right arm) as documented in the medical record.
