S45.0
Injury of axillary artery
Clinical Classification Guidelines
Medical Intelligence & Overview
An injury to the axillary artery, classified under ICD-10 code S45.0, involves damage to a major blood vessel that supplies blood to the upper limb. The axillary artery runs through the armpit and is a crucial component of the circulatory system for the arm and shoulder. Traumatic injuries, including cuts, fractures, or blunt force impacts, can cause varying degrees of damage to this artery. Such injuries require prompt medical attention to prevent severe complications, such as blood loss, ischemia, or the need for surgical intervention.
Causes & Symptoms
Clinical Causes: Trauma resulting from accidents such as falls or vehicle collisions Penetrating injuries like stab or gunshot wounds Fractures of the clavicle or upper ribs that can damage the artery Blunt force trauma to the shoulder or chest area Surgical complications involving the shoulder or armpit area
Key Symptoms: Severe pain in the shoulder or upper arm Swelling or a lump in the armpit Significant bleeding or blood loss Paleness or coldness in the arm or hand Weakness or numbness in the arm, hand, or fingers Decreased or absent pulse in the affected arm Possible visible bruising or discoloration
Diagnostic & Treatment
Diagnosis Path: Doppler ultrasound to evaluate blood flow Computed tomography angiography (CTA) for detailed vessel visualization Magnetic resonance angiography (MRA) to assess blood vessel integrity Conventional angiography in complex cases
Treatment Protocols: Emergency surgical repair to restore artery integrity Vascular bypass procedures if the artery is extensively damaged Hemostatic techniques to control bleeding during surgery Supportive care, including fluid resuscitation and blood transfusions if necessary Postoperative monitoring for complications such as re-bleeding or infection Rehabilitation exercises for recovery of shoulder function and strength
