Knowledge of the venous systems of the neck is important in microvascular anastomosis as well as to avoid unintended bleeding during neck dissection.
We present three rare variations of the jugular system of the neck which could have complicated neck dissection.
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.
Careful dissection was carried out to avoid complications and to preserve the vessels for microvascular anastomosis.
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.
了解颈部静脉系统对于微血管吻合以及避免颈部解剖过程中意外出血非常重要。
我们展示了三例颈部颈静脉系统罕见变异，这些变异可能使颈部解剖变得复杂。
第一例是来自颈内静脉（IJV）的后支。第二例是直径增加至3厘米的颈内静脉，第三例是颈外静脉动脉瘤。
进行了仔细的解剖以避免并发症，并保留血管用于微血管吻合。
术中及术后均未出现并发症。
应谨慎处理与正常解剖结构的差异，以避免并发症，并精确有效地进行手术。
