Internal jugular vein is one of the major contributors to the venous drainage from the intracranial structures. Neck dissections which necessitates ligation of internal jugular vein leads to significant alteration of cerebrospinal fluid pressures in the range of three times for unilateral ligation to five times in cases of bilateral ligation. Agenesis of internal jugular vein merits concern prior to central venous cannulation and ligation during radical neck dissection for metastatic nodes in head and neck cancers.
颈内静脉是颅内结构静脉引流的主要贡献者之一。需要结扎颈内静脉的颈部清扫术会导致脑脊液压力显著改变,单侧结扎时压力变化范围为三倍,双侧结扎时则为五倍。在对头颈部癌症转移性淋巴结进行根治性颈部清扫术时,在进行中心静脉插管和结扎之前,颈内静脉缺如值得关注。
