• Primary Survey: The initial assessment follows the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure). Ensuring airway patency and adequate breathing is crucial, especially if there is significant blood loss.
• Hemodynamic Stabilization: Patients may present with hypovolemic shock due to blood loss. Immediate intravenous (IV) access for fluid resuscitation and blood transfusions is essential to stabilize the patient[1].

2. Imaging Studies

• CT Angiography: This is often the preferred imaging modality to assess the extent of vascular injury and to visualize associated injuries in the abdomen and pelvis. It provides rapid and detailed information about the vascular status[2].
• Ultrasound: In some cases, a focused assessment with sonography for trauma (FAST) may be used to detect free fluid or hematomas, although it is less definitive for vascular injuries compared to CT[3].

Surgical Intervention

1. Indications for Surgery

• Surgical intervention is indicated in cases of significant arterial or venous injury, particularly if there is active hemorrhage, vascular compromise, or associated injuries that require surgical management[4].

2. Surgical Techniques

• Direct Repair: If the injury is a laceration or transection, direct surgical repair of the artery or vein may be performed using sutures or vascular grafts.
• Endovascular Techniques: In some cases, endovascular stenting may be an option, particularly for injuries that are amenable to this less invasive approach. This is more common in arterial injuries[5].
• Bypass Grafting: In cases where the injury is extensive or involves significant tissue loss, bypass grafting may be necessary to restore blood flow[6].

Postoperative Care and Monitoring

1. Monitoring for Complications

• Patients require close monitoring for complications such as re-bleeding, thrombosis, or infection. Regular assessments of limb perfusion and vital signs are critical in the postoperative period[7].

2. Rehabilitation

• Depending on the extent of the injury and the surgical intervention, rehabilitation may be necessary to restore function and mobility. This can include physical therapy and occupational therapy to aid recovery[8].

Conclusion

The management of iliac artery or vein injuries classified under ICD-10 code S35.51 involves a comprehensive approach that includes initial stabilization, imaging for assessment, and surgical intervention when necessary. The choice of surgical technique depends on the nature and severity of the injury. Postoperative care is crucial to monitor for complications and facilitate recovery.
