Rare Neck Venous Anatomy Anomalies - A Case Report.

ABSTRACT

Rationale Knowledge of the venous systems of the neck is important in microvascular anastomosis as well as to avoid unintended bleeding during neck dissection. Patient Concerns We present three rare variations of the jugular system of the neck which could have complicated neck dissection. Diagnosis The first case is of a posterior tributary from an internal jugular vein (IJV). The second case is an IJV with increased diameter of 3 cm and the third case is an aneurysm of the external jugular vein. Treatment Careful dissection was carried out to avoid complications and to preserve the vessels for microvascular anastomosis. Outcome: No complications were encountered intraoperatively and post-operatively. Take-away Lessons Variations from normal anatomy should be dealt with caution to avoid complications and to perform surgery precisely and efficiently.
