S45.191

Clinical Causes: Blunt trauma or impact from falls or accidents Penetrating injuries like stab wounds or gunshot wounds Fractures involving the humerus bone near the artery Surgical complications or iatrogenic injuries during procedures Crush injuries from heavy objects or machinery Severe arm contusions

Key Symptoms: Sudden and intense pain in the arm Swelling or bruising around the upper arm Diminished or absent pulse in the wrist or hand Coldness or pallor of the hand and fingers Weakness or numbness in the arm or hand Motor function loss or inability to move fingers or hand Signs of shock in severe cases, such as dizziness or fainting

Diagnosis Path: Diagnosis of a brachial artery injury typically involves a combination of physical examination and imaging studies. Healthcare providers may check for pulse presence, limb temperature, and color to assess blood flow. Imaging techniques used include duplex ultrasonography, which visualizes blood flow, or more advanced methods such as computed tomography angiography (CTA) or magnetic resonance angiography (MRA). In some cases, surgical exploration may be required to confirm the injury and identify the exact location and extent of damage.

Treatment Protocols: Treatment approaches aim to restore adequate blood flow and prevent complications such as limb ischemia or tissue death. These may include: - **Emergency surgery:** To repair or bypass the injured segment of the artery, using techniques like end-to-end anastomosis or grafting with vein segments. - **Vascular repair or reconstruction:** Depending on the severity and nature of the injury. - **Management of associated injuries:** Addressing any fractures, nerve injuries, or soft tissue damage. - **Postoperative care:** Including blood flow monitoring, antibiotics to prevent infection, and measures to reduce swelling. - **Rehabilitation:** Physical therapy to regain strength and function in the affected arm. Prompt medical attention is crucial to prevent severe complications and ensure optimal recovery.
