摘要
Internal jugular vein duplication (IJVD) is a rare phenomenon. Twenty-one such instances in 18 individuals have been reported to date. We report an intra-operative case of unilateral IJVD in a 32-year-old male, who was operated for cancer of gingivobuccal sulcus. We have reviewed the published literature and have proposed a classification scheme in order to make future reporting systematic. The condition has been classified into type A, B and C based on their morphology. About 75 % of the reported cases are of Type A. Type C is the most complex of all the duplications. Though IJVD is physiologically inconsequential, it has clinical implications. Percutaneous catheterisation of the vein could be hazardous in all cases, but more so in type B and C duplications. As with any anomaly, the risk of accidental injury increases during surgical procedures. It is important to document findings of this anomaly in order to understand its anatomy and implications in a better way. © 2015, Indian Association of Surgical Oncology.
