S75.12

Clinical Causes: Traffic accidents involving high-impact collisions Falls from significant heights Penetrating injuries caused by knives, glass, or other sharp objects Blunt force trauma during sports or physical altercations Surgical injuries or complications

Key Symptoms: Sudden, intense pain in the upper leg or groin area Rapid swelling or a palpable mass in the thigh or hip Unusual bleeding or bruising in the thigh Visible open wound or laceration in the affected region Signs of blood loss such as dizziness, weakness, or fainting Possible difficulty moving the leg

Diagnosis Path: Diagnosing a major femoral vein laceration involves a combination of clinical evaluation and imaging tests. Healthcare providers typically perform a physical examination to assess for external injuries and signs of bleeding. Imaging modalities such as duplex ultrasound, CT angiography, or MRI may be employed to evaluate the extent of the vascular injury, identify bleeding, and plan appropriate treatment. Sometimes, an arteriogram is used to examine arterial and venous structures in detail.

Treatment Protocols: Effective management of a femoral vein laceration aims to control bleeding, repair the vessel, and prevent complications such as blood clots or severe blood loss. Treatment options include: - **Emergency hemostasis:** Applying direct pressure to control active bleeding - **Surgical repair:** Often necessary to suture or ligate the damaged vein and restore normal blood flow - **Vascular surgery techniques:** Such as vein grafting or patch repair in complex injuries - **Blood transfusions:** To replace lost blood and stabilize the patient - **Post-operative care:** Includes anticoagulation therapy, infection prevention, and monitoring for signs of deep vein thrombosis or other complications
