- Ultrasound: While less definitive than a CT scan, it can be used in emergency settings to assess for free fluid in the abdomen, which may indicate bleeding.
- MRI (Magnetic Resonance Imaging): Rarely used in acute settings but can provide detailed images of soft tissue and vascular structures.

Angiography

In some cases, a contrast-enhanced angiography may be performed to visualize blood flow and identify the exact location and severity of the laceration.

Laboratory Tests

Blood Tests

• Complete Blood Count (CBC): To assess for anemia due to blood loss.
• Coagulation Profile: To evaluate the blood's ability to clot, which is critical in managing trauma patients.

Surgical Evaluation

In cases of suspected major vascular injury, surgical consultation is often warranted. Surgeons may perform exploratory surgery if imaging studies indicate significant injury or if the patient's condition deteriorates.

Conclusion

The diagnosis of a major laceration of the inferior vena cava (ICD-10 code S35.12) relies on a combination of clinical assessment, imaging studies, and laboratory tests. Prompt recognition and intervention are crucial due to the potential for life-threatening complications associated with this type of injury.
