Background: Unexpected variations of the external jugular veins should be aware in the hope of preventing inadvertent injury.
Aims: The aim of the present study is report a rare and non-reported unilateral anatomical variation of the venous drainage of head and neck.
Materials and Methods: The anatomical variations were found during a routine dissection performed in the laboratory of Morphology of the University of Pamplona.
Findings: The common facial vein had a similar location and course as the EJV. Hence, this vein was termed as the second external jugular vein and drain into the subclavian vein. External Jugular Vein terminated into the jugulosubclavian junction. The external jugular vein presented two fenestrations. The suprascapular vein drains into the external jugular vein. The transverse cervical veins drains into the second external jugular vein
Conclusion: Combination of double fenestration with double external jugular vein and anomalous venous drainage patterns is a rare anomaly.
