摘要

背景:本研究旨在了解下肢淋巴水肿患者体位改变时淋巴血管和静脉的变化情况。方法:我们对连续18例(33条肢体)下肢淋巴水肿患者行淋巴-静脉吻合术(LVA)进行回顾性研究。术前行超声检测合适的淋巴管和静脉,应用D-CUPS(多普勒、交叉、不可折叠、平行、浅筋膜)指数识别淋巴管。我们在患者躺着、坐着和站着的情况下,利用超声测量LVA各切口处淋巴管和静脉的垂直直径,并进行Student’st检验。结果:参与者的平均年龄为61.8岁,平均体重指数为21.7(范围:18.3-28.1)。对30只大腿上的38个部位和18只小腿上的21个部位进行了评估。当躺姿变为坐姿或站姿时,静脉直径显著增加(大腿:p < 0.01,小腿:p = 0.016和0.015),而淋巴管直径无显著增加(大腿:p = 0.65,小腿:p = 0.60和0.36)。小腿静脉和淋巴管扩张率之间存在弱相关性(r = 0.39, p = 0.030)。结论:由仰卧位变为站立位时,静脉明显扩张,淋巴管无明显扩张。今后需要进行更多病例的类似研究。

Changes in the Diameter of Lymphatic Vessels and Veins Due to Body Position, Evaluated by Ultrasound.

Background: The purpose of this study was to clarify how lymphatic vessels and veins change when body position is changed in lower limbs affected by lymphedema. Methods: We performed a retrospective study of 18 consecutive patients (33 limbs) who underwent lymphaticovenous anastomosis (LVA) for lower limb lymphedema. We performed ultrasound to detect the suitable lymphatic vessels and veins preoperatively, applying the index of D-CUPS (Doppler, Crossing, Uncollapsible, Parallel, and Superficial fascia) to identify lymphatic vessels. We measured the vertical diameter of the lymphatic vessels and veins in each incision site for LVA using ultrasound with the patients lying, sitting, and standing, and a Student's t test was performed. Results: The mean age of the participants was 61.8 years old, and the mean body mass index was 21.7 (range: 18.3-28.1). Thirty-eight sites on the 30 thighs and 21 sites on the 18 calves were evaluated. The diameter of veins increased significantly when changing from a lying to a sitting or a standing position (thigh: p < 0.01, calf: p = 0.016 and 0.015, respectively), but lymphatic vessels did not (thigh: p = 0.65, calf: p = 0.60 and 0.36, respectively). A weak correlation was found between dilatation rates of veins and lymphatic vessels in the calf (r = 0.39, p = 0.030). Conclusion: The veins dilated significantly when the body changed from the supine to standing position, but the lymphatic vessels did not. Similar studies with a larger number of cases are desirable in the future.
