摘　　要：目的通过对不同体位下左右两侧颈内静脉的彩色多普勒超声对照观察,为颈清术中是否应陔保留颈内静脉提供理沦依据。方法选取40例青下健康志愿者。受检者平静呼吸.采用彩超观测左右两侧颈内静脉在卧位和坐位下的血流动力学参数变化情况。结果卧位时,右侧颈内静脉横截面积、血流速度和血流量分别比左侧大58%、23%和91%,差异具有统计学意义;26例(65%)患者颈内静脉为右优势型.10例(25%)为对称型,4例(10%)为左优势型;颈内静脉血流总量占脑总血流量的74%.其中29例(72%)受检者为颈内静脉优势型,9例(22%)为均衡型,2例(5%)为其他静脉优势型。坐位时,右侧颈内静脉横截面积、血流速度和血流量分别比左侧大29%、35%和56%,其中血流速度和血流量的差异具有统计学意义;18例(45%)患者颈内静脉为右优势型.18例(45%)为对称型.4例(10%)为左优势型;颈内静脉血流总量占脑总血流量的23%.其中无颈内静脉优势型,9例(22%)为均衡型,31例(77%)为其他静脉优势型。结论左右两侧颈内静脉存在不对称性,坐位时,颈内静脉并非颅内静脉的主要颅外回流通道。术前彩色多普勒超声检查能够为颈清术于术方式的选择提供依据。Objective Right and left internal jugular veins（IJV）under different body position were observed by color-coded Doppler sonography,in order to provide an experimental basis for the preservation of IJV in neck dissections. Methods A total of 40 volunteers were examined in this study. The hemodynamic data such as section area,velocity,and volume of blood flow were measured by Doppler under supine and sitting position in eupnoea. Results In supine position,the section area, the velocity and the blood flow volume in the right side were 58%00,23% and 91%, which were more than left side respectively. In the 40 volunteers, 26 （65 % ）patients were right side advantages IJV, 10 （25%）were symmetrical IJV,4（10%）were left side advantages IJV. The outflow of IJV was 74% of total outflow,and 29 （ 73 % ） patients were jugular drainage, 9 （ 23 % ） were symmetrical drainage, 2 （ 5 % ） were non jugular drainage. In sitting position, the section area,the velocity and the blood flow volume in the right side were 29%, 35 % and which were 56 % more than left side respectivelys, In the 40 volunteer, 18 （45 % ） patients were right side advantages IJV, 18 （ 45 % ） were symmetrical IJV,4（10%）were left side advantages IJV. The outflow of IJV was 23% of total outflow, and 9 （23 % ） were symmetrical drainage and 31 （78%） were non jugular drainage. Conclusions There is bilateral difference of IJV. With quiet breathing,IJV is not the main path of the outflow of cerebral venous system in sitting position. The preoperative sonography is useful to design individual surgical approach for the neck dissections.
