S35.512 Injury of left iliac artery

Name of the Condition

• Injury of left iliac artery

Summary

An injury of the left iliac artery involves damage to the vascular structure supplying blood to the left lower extremity and pelvic organs. This condition requires prompt evaluation to assess vascular integrity and prevent complications such as hemorrhage or ischemia.

Causes

Direct trauma to the pelvis or lower abdomen, such as from motor vehicle accidents, falls, or penetrating injuries. Blunt force impact or crush injuries that disrupt vascular integrity. Iatrogenic causes, including surgical procedures or medical interventions in the pelvic region.

Risk Factors

• Participation in high-risk activities with potential for pelvic trauma.
• Occupations involving exposure to machinery or environments with crush hazards.
• Pre-existing vascular conditions that may predispose to injury.
• Advanced age, which can affect tissue elasticity and healing.

Symptoms

• Pain, swelling, or tenderness in the pelvic or groin region.
• Visible bruising or discoloration over the injured area.
• Signs of internal bleeding, such as hypotension or tachycardia.
• Altered skin temperature or sensation in the lower extremities.
• Possible hematoma or pulsatile mass at the injury site.

Diagnosis

Physical examination to assess for signs of trauma or hemodynamic instability. Imaging studies, such as CT angiography or duplex ultrasound, to evaluate vascular damage and blood flow. Laboratory tests to check for anemia or coagulopathy.

Treatment Options

Immediate stabilization of hemodynamics, including fluid resuscitation or blood transfusion. Surgical repair or endovascular intervention to restore arterial flow. Monitoring for complications like compartment syndrome or infection.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Regular follow-up to assess vascular function and detect late complications, such as aneurysm formation or stenosis.

Complications

Hemorrhage, ischemia of the lower extremity, pseudoaneurysm, arteriovenous fistula, or infection. Long-term risks include chronic pain or functional impairment.

Lifestyle & Prevention

Avoid high-risk activities without proper safety measures. Use protective equipment in hazardous environments. Maintain vascular health through regular exercise and management of underlying conditions like hypertension.

When to Seek Professional Help

Seek immediate medical attention for severe pelvic or abdominal pain, uncontrolled bleeding, or signs of shock (e.g., dizziness, rapid heartbeat). Follow up with a vascular specialist if symptoms persist or worsen.

Tips for Medical Coders

Code S35.512 is specific to the left iliac artery. Document the laterality (left) and confirm the injury is not combined with other vascular structures. Ensure clinical documentation supports the diagnosis and treatment provided.
