This study details unusual variations in the left neck veins, including duplicated internal jugular vein and facial vein continuation. Understanding these anatomical differences is crucial for head and neck surgeons and radiologists.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Radiology

Background:

  • Variations in head and neck veins are clinically significant for surgical procedures and radiological interventions.
  • Accurate anatomical knowledge is essential for safe and effective medical practice.

Observation:

  • Multiple venous variations were observed on the left side of the neck.
  • Specific anomalies included absence of the anterior division of the retromandibular vein, continuation of the facial vein as the anterior jugular vein, and duplication of the internal jugular vein above the hyoid bone.

Findings:

  • A large communicating vein connected the anterior jugular vein and the anterior division of the internal jugular vein.
  • The lingual vein drained into this communicating vein.
  • The jugular venous arch was abnormally large, doubled, and highly placed.

Implications:

  • These detailed anatomical findings are vital for surgeons performing head and neck procedures.
  • Radiologists performing catheterizations benefit from this knowledge to avoid complications.
  • Enhanced understanding of venous anomalies improves patient care and diagnostic accuracy.
