Hand ischaemia after radial artery cannulation

Area of Science:

• Critical care medicine
• Vascular surgery
• Trauma surgery

Background:

• Arterial cannulation is standard for hemodynamic monitoring in critically ill adults.
• Thrombosis is the most frequent complication associated with arterial cannulation.
• Early recognition and management of complications are crucial for patient outcomes.

Observation:

• A patient with multiple traumatic injuries underwent radial artery cannulation.
• The cannulation procedure was followed by the development of compartment syndrome in the forearm and hand.
• Compartment syndrome presents as a surgical emergency requiring prompt diagnosis and intervention.

Findings:

• Radial artery cannulation in this trauma patient was associated with the development of compartment syndrome.
• This case highlights a rare but severe complication potentially linked to arterial cannulation.
• The clinical presentation suggests a possible thrombotic event obstructing arterial flow, leading to ischemia and swelling.

Implications:

• Clinicians should maintain a high index of suspicion for compartment syndrome following arterial cannulation, especially in trauma patients.
• Prompt diagnosis and surgical intervention are vital to prevent irreversible tissue damage and functional loss.
• Further investigation into the mechanisms linking arterial cannulation to compartment syndrome may inform preventative strategies.
