S35.51 Injury of iliac artery or vein

Name of the Condition

• Injury of iliac artery or vein

Summary

An injury of the iliac artery or vein involves damage to the major vascular structures supplying or draining blood from the pelvis and lower extremities. 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 ultrasound, to evaluate vascular damage. Laboratory tests to assess for blood loss or coagulopathy.

Treatment Options

Surgical repair or reconstruction of the injured vessel. Endovascular procedures, such as stenting or embolization, to manage bleeding or restore blood flow. Supportive care, including fluid resuscitation and blood transfusion, to stabilize the patient.

Prognosis and Follow-Up

Prognosis depends on the extent of vascular injury and promptness of treatment. Regular follow-up to monitor for complications, such as rebleeding or vascular stenosis. Long-term surveillance may be necessary to assess healing and functional recovery.

Complications

Hemorrhage or uncontrolled bleeding. Ischemia or reduced blood flow to the lower extremities. Vascular stenosis or occlusion. Infection at the injury site. Thrombosis or embolism.

Lifestyle & Prevention

Avoid high-risk activities that may lead to pelvic trauma. Use protective equipment during occupations with crush hazards. Maintain vascular health through regular exercise and a balanced diet. Seek prompt medical care for pelvic or abdominal injuries.

When to Seek Professional Help

Severe pain, swelling, or bruising in the pelvic region. Signs of internal bleeding, such as dizziness, fainting, or low blood pressure. Altered sensation or color in the lower extremities. Pulsatile mass or hematoma at the injury site.

Tips for Medical Coders

Code S35.51 is used for injury of the iliac artery or vein. Documentation should specify the affected vessel (artery or vein) and the nature of the injury (e.g., laceration, contusion). Include details of the encounter (initial, subsequent, or sequela) as applicable. Ensure clinical correlation with imaging or procedural findings to support coding accuracy.
