摘要

目的　利用基于CE-MRV的三维重建成像观察小脑幕静脉窦及幕上、幕下桥静脉的形态特征，探讨其临床意义。方法　随机抽取本院2016年1月至2019年11月80例3D CE-MRV受检者，通过Stealth Station S7神经导航系统中的StealthViz程序建立小脑幕-静脉三维重建模型，分析小脑幕静脉窦及幕上、下桥静脉的形态特点。结果　小脑幕窦可分为内侧型、中间型、外侧型，其常见的汇流部位依次为横窦（尤其中后部）、窦汇、直窦和岩上窦。小脑幕上桥静脉可分为单干型、多干型、烛台型、静脉湖型，以多干型最常见。小脑幕下桥静脉可分为小脑幕组、窦汇组、岩部组，其中汇入窦汇区的桥静脉分布比较集中。结论　三维重建成像可以有效观察小脑幕区的静脉解剖；熟悉小脑幕区脑静脉的解剖及引流特点，对该区域手术的入路设计及相邻桥静脉的保护有指导意义。

Abstract

Objective　To observe the morphological characteristics of tentorial sinus and bridging veins of tentorium using three-dimensional visualization technology based on CE-MRV, and to explore its clinical significance. 　Methods　Eighty patients who underwent 3D CE-MRV examination in our hospital from January 2016 to November 2019 were randomly selected, and a 3D reconstruction model of the tentorium-veins was established by the StealthViz program in the Stealth Station S7 neuronavigation system. The morphological characteristics of tentorial sinus and bridging veins of tentorium were analyzed.　Results The tentorial sinus can be divided into a medial group, a middle group, and a lateral group. Their common confluence sites from more to less were the transverse sinus, torcular herophili, straight sinus, and superior petrosal sinus. The bridging veins from above the tentorium can be divided into single stem type, multiple stem type, candelabra type, and venous lakes type. Among them, the multiple stem type was the most common type. The cerebellar bridging veins below the tentorium can be divided into a tentorial group, a torcular herophili group, and a petrosal group. The distribution of the bridging vein joining the torcular?herophili was relatively concentrated. 　Conclusions　Three-dimensional visualization technology can effectively display the venous anatomy in the tentorium region of the cerebellum, help to understand the anatomy and drainage characteristics of the cerebral vein in the tentorium area, which is of guiding significance to the design of surgical approach and the protection of the adjacent bridging veins.
