颞叶桥静脉的显微解剖及临床意义

目的：系统了解颞叶桥静脉及其属支的显微解剖。方法：在手术显微镜下观察10例20侧成人头部标本的颞叶桥静脉，由各属支起源追踪至静脉汇入点，测量有关数据。结果：颞叶桥静脉有4型：Ⅰ静脉湖型15％(3侧)，Ⅱ烛台型40％(8侧)，Ⅲ单干型20％(4侧)，Ⅳ多干型25％(5侧)。20侧半球共有107条桥静脉属支、43个静脉汇入点，静脉汇入点分布于横窦区54％(23个)、小脑幕区23％(10个)、颞骨岩部区23％(10个)。结论：熟悉颞叶桥静脉的显微解剖，是在相关手术中保护桥静脉的基础。

Microanatomy and clinical application of the temporal bridging vein

Objective: To investigate systematically the microanatomy of the temporal bridging vein and its tributaries. Methords: On 10 adult cadaver brain specimens (20 hemispheres), the temporal bridging veins were studied under an operating microscopy, from the origins of their tributaries to their terminations. Results: Four venous configurations were found: venous lakes (tentorial sinuses) running in the tentorium before entering the sinuses 15%(3 sides), the candelabra of veins uniting to form one large draining vein 40%(8 sides), single independent draining vein 20%(4 sides) and multiple independent draining veins 25%(5 sides). 107 tributaries and 43 terminations of the temporal bridging veins were found in our specimens .The locations of the terminations of the bridging veins were divided into three groups : the transverse sinus group 54%(23), the tentorial group 23%(10) and the petrosal group 23%(10). Conclusions: Knowledge of this venous anatomy can protect bridging veins well in the operation with less venous complications.
