Neck dissection is routine for the management of cancers of the head and neck. Knowledge of anatomical variants in the carotid artery system at various levels of dissection should prevent inadvertent injury to major blood vessels, which can cause massive bleeding. We report a rare 180° sharp bend in the cervical course of the internal carotid artery at level II, which we found during a modified neck dissection.
颈部清扫术是头颈部癌症治疗的常规操作。了解在不同清扫层面颈动脉系统的解剖变异，应可防止意外损伤主要血管，否则可能导致大出血。我们报告了一例罕见的颈内动脉在II区颈部走行呈180°锐角弯曲的情况，这是我们在改良颈部清扫术中发现的。
