Internal Jugular Vein (IJV) is an important landmark for Head and Neck surgeons during oncological clearance of disease from neck and microvascular reconstruction as well as for the intensivist during central line insertion. Detailed knowledge of the IJV anatomy and its variations is important to avert any catastrophic complications during surgery.
Data of 350 patients was recorded prospectively and analysed over a period of two years and presence of IJV duplication was documented as percentages
A total of 350 patients with diagnosed oral cavity carcinoma were included who underwent neck dissection out of which seven patients were identified with Internal Jugular Vein duplication making it an institutional clinical prevalence of around 2%.
IJV duplication is inadvertently found intra operatively on maximum number of occasions therefore to avoid the risk of iatrogenic injury and undesired complications, preoperative imaging should be carefully assessed while planning the patient for surgery.
颈内静脉（IJV）是头颈外科医生在颈部肿瘤清除和微血管重建手术中的重要标志，也是重症监护医生在插入中心静脉导管时的重要标志。详细了解颈内静脉的解剖结构及其变异对于避免手术期间的任何灾难性并发症至关重要。
前瞻性记录350例患者的数据，并在两年时间内进行分析，颈内静脉重复的情况以百分比记录。
总共纳入了350例经诊断患有口腔癌并接受颈部清扫术的患者，其中7例被发现有颈内静脉重复，这使其在本机构的临床患病率约为2%。
颈内静脉重复在大多数情况下是在手术中无意中发现的，因此为避免医源性损伤和不良并发症的风险，在为患者制定手术计划时应仔细评估术前影像。
