BACKGROUND
Until recently, vascularized lymph-node flaps were based on arterial and venous donor vessels. Now, venous lymph-node flaps form a novel promising concept in the treatment of advanced-stage lymphedema. In preliminary studies, the external jugular vein has shown promising results as a venous lymph-node flap. However, nothing is known about the number of lymph nodes adjacent to the external jugular vein.
METHODS
Standardized specimens of the external jugular vein and surrounding fatty tissue directly overlying the sternocleidomastoid muscle were obtained during routine neck dissection. Histologic evaluation was performed in order to evaluate for the presence of lymph nodes within the tissue.
RESULTS
A total of 20 specimens were evaluated. There was no vein in 4 of the samples. We found lymph nodes in 9 of the remaining 16 samples. In 7 samples, lymph nodes were absent.
CONCLUSION
Our results suggest that the vein directly overlying the sternocleidomastoid muscle may not be the ideal candidate for a venous lymph-node flap.
背景
直到最近，带血管蒂淋巴结皮瓣都是基于动脉和静脉供体血管构建的。如今，静脉淋巴结皮瓣在晚期淋巴水肿的治疗中形成了一个新的有前景的概念。在初步研究中，颈外静脉作为静脉淋巴结皮瓣已显示出有前景的结果。然而，关于颈外静脉旁淋巴结的数量尚无相关信息。
方法
在常规颈部解剖过程中获取覆盖胸锁乳突肌的颈外静脉及周围脂肪组织的标准化标本。进行组织学评估以判断组织内是否存在淋巴结。
结果
共评估了20个标本。4个样本中没有静脉。在其余16个样本中的9个发现了淋巴结。7个样本中没有淋巴结。
结论
我们的结果表明，直接覆盖胸锁乳突肌的静脉可能不是静脉淋巴结皮瓣的理想选择。
