Aberrant innominate artery may complicate a potentially safe surgery

Area of Science:

• Anatomy
• Surgical Procedures
• Vascular Anomalies

Background:

• Anterior neck surgeries, including thyroidectomy and tracheotomy, are generally safe with low mortality rates.
• Hemorrhage is a primary cause of death following tracheotomy and thyroid surgery.
• Standard surgical approaches to the trachea do not typically involve major vessels.

Observation:

• A rare case of an aberrant innominate artery crossing anterior to the trachea was identified.
• This anomaly was located just below the thyroid isthmus.
• The aberrant vessel presented a significant risk of catastrophic bleeding.

Findings:

• Aberrant innominate artery is an uncommon anatomical variation.
• Unawareness or complacency during surgery can lead to life-threatening hemorrhage.
• Early identification is crucial for patient safety.

Implications:

• Surgeons must maintain vigilance for aberrant arteries in the anterior neck surgical field.
• Preoperative awareness and intraoperative caution can prevent accidental injury to aberrant vessels.
• Preventing complications ensures the safety of procedures like tracheotomy and thyroid surgery.
