S55.012

Clinical Causes: Accidental cuts or lacerations from knives, blades, or glass during everyday activities or work. Trauma during sports or recreational activities that involve the arms. Falls or direct blows to the forearm that cause a tear in the artery. Motor vehicle accidents or crush injuries involving the arm. Surgical injuries or complications during medical procedures.

Key Symptoms: Intense bleeding from the wound, which may be rapid or steady. Swelling or swelling around the injury site due to blood accumulation. Pain, throbbing, or tenderness in the forearm or hand. Weakness or numbness in the hand or fingers from compromised blood flow. Palor or a bluish discoloration of the hand or fingers due to reduced blood supply. A pulselessness in the affected arm can be a sign of arterial injury. Possible formation of a hematoma (a collection of blood under the skin).

Diagnosis Path: Physical assessment of the pulse distal to the injury to determine if blood flow is compromised. Ultrasound imaging (Doppler ultrasound) to visualize blood flow and identify the injury. Angiography, an imaging technique involving contrast dye, to precisely locate the tear in the artery. X-rays to assess for other associated bone injuries.

Treatment Protocols: Applying direct pressure to stop bleeding immediately. Immobilizing the arm to prevent further injury. Transporting to a healthcare facility promptly for surgical intervention. Surgical repair of the damaged artery, which may involve suturing the tear or bypass procedures if necessary. Administering antibiotics to prevent infection, especially if the wound is contaminated. Monitoring for signs of compartment syndrome, a serious condition caused by increased pressure within the muscles. Postoperative care includes wound management, pain control, and physical therapy to restore function.
