• Anterior jugular vein
• External jugular vein
• Catheterization

Introduction: Paired anterior jugular veins were present on either side of the midline of the neck, connected by a transverse (jugular) venous arch in the suprasternal space and drains into the external jugular vein (EJV) and subclavian vein (SV).
Method: The current variations were found in approximately 50-year-old female cadaver during routine dissection in the Department of Anatomy.
Observation: In present case, the anterior jugular venous system presents a variant formation, course and termination. Anterior jugular veins (AJVs) formed "V1'' at the level of third tracheal ring; the major part of the "V1'' deviated towards right side and joined with EJV forming "V2''. The "V2'' finally drained into the right jugulo subclavian junction. Clinically, the variant arrangement of AJV may involve malposition of the catheter and misinterpretation of the examination of cardiovascular system.
Conclusion: Knowledge of such variations of AJV is important for medical professionals to avoid any clinical mismanagement during cardiac examination, vascular surgeries, anesthetic and radiological procedures.
