S35.50

Clinical Causes: Motor vehicle accidents Falls from heights Penetrating injuries such as stab or gunshot wounds Surgical or medical procedures involving the pelvis Traumatic sports injuries Crush injuries or severe blunt force trauma

Key Symptoms: Sudden and intense pain in the pelvic or groin area Swelling or tenderness over the pelvis or lower abdomen Signs of internal bleeding such as dizziness, weakness, or fainting Rapid heartbeat (tachycardia) Low blood pressure (hypotension) Palor or pallor of the skin, indicating blood loss Reduced or absent pulses in the lower extremities

Diagnosis Path: Healthcare professionals rely on a combination of clinical evaluation and diagnostic tests. Initial assessments include a physical examination to check for tenderness, swelling, or signs of bleeding. Imaging studies are essential for confirming vascular injuries. These may include: - **Ultrasound (Doppler sonography):** To evaluate blood flow and detect bleeding. - **Computed Tomography (CT) Angiography:** To visualize blood vessels and identify areas of injury. - **Conventional Angiography:** An invasive procedure that uses contrast dye to visualize blood vessels in detail. Laboratory tests, such as complete blood counts, can help assess the extent of blood loss.

Treatment Protocols: Management of iliac blood vessel injuries often requires urgent medical intervention. Options include: - **Blood transfusions:** To replace lost blood and stabilize blood pressure. - **Surgical repair:** Procedures to repair or ligate damaged blood vessels. This might involve bypass grafting or vascular reconstruction. - **Endovascular techniques:** Minimally invasive procedures like stent placement or embolization, especially when surgery poses high risks. - **Monitoring and supportive care:** Including stabilization of vital signs and addressing concurrent injuries. The specific treatment depends on the severity and location of the injury, as well as the patient's overall condition.
