摘　　要：目的:通过对上矢状窦引流桥静脉的彩色多普勒超声观察,为脑静脉血流动力学研究提供新的参考数据。方法:选择20例神经外科开颅术后1年的患者,经术后骨窗彩超观测上矢状窦引流桥静脉。结果:桥静脉呈节段性集中分布,分为前段组和后段组两组。前段组桥静脉数目为(3.1±1.4)支,直径为(2.7±0.7)mm,注入角度为(96±33)°,平均血流速度为(10.0±2.8)cm/s。后段组桥静脉数目为(5.8±1.0)支,直径为(3.2±1.2)mm,注入角度为(41±24)°,平均血流速度为(11.4±2.8)cm/s。与前段组相比较,后段组桥静脉的数目较多,直径较大,注入角度较小,血流速度较快。结论:彩色多普勒超声通过术后骨窗能够观测到上矢状窦引流桥静脉的形态和血流速度,为脑静脉血流动力学研究提供了新的参考数据,并为神经外科术后监测提供了新的方法。Objective： To observe the cerebral bridging veins （BVs） entering into superior saggital sinus （SSS） by color-coded duplex sonography, for provide new hemodynamic reference data for clinical application. Methods： Twenty patients undergoing selective craniotomy about one years and having a good recovery underwent color-coded duplex sonography. The number, diameter and angle of the BVs, the velocity of the SSS and BVs were measured through the surgical bone window. Results： The BVs formed two clusters along the SSS： anterior group and posterior group. The number of the anterior group BVs was （3.1±1.4）, the diameter （2.7±0.7） mm, the angle （96±33）°, and the mean flow velocity （10.0±2.8） cm/s. The number of the posterior group BVs was （5.8±1.0）, the diameter （3.2±1.2） mm, the angle （41±24）°, and the mean flow velocity （11.4± 2.8） cm/s respectively. The number, diameter and the mean flow velocity of the posterior group BVs were larger than that of anterior group. Conclusions： The morphological feature and velocity of BVs entering into SSS can be measured through the surgical bone window under color-coded duplex sonography.
