| 目的 通过容积CT数字减影血管造影(VCTDSA)探讨上矢状窦旁桥静脉的解剖学表现及蛛网膜颗粒与桥静脉的关系。 方法 分析102例患者的资料,观测上矢状窦旁桥静脉的数目、形态、大小、汇入上矢状窦的部位和角度;蛛网膜颗粒的部位、大小及与桥静脉的关系。 结果 102例共有桥静脉837支,以中部最多(约2支/侧),后部最少(约1支/侧),前部主要集中在起始点附近;桥静脉大致有三类形态:圆管状或带状(65.95%)以前部和后部居多、扁平不规则形(24.73%)以中部居多、扁平筛孔状(9.31%)主要位于中部;桥静脉汇入上矢状窦的部位前部以窦基底部汇入为主,中部以窦中部水平汇入稍多,后部则主要从窦下缘汇入;桥静脉汇入上矢状窦的角度前部主要以直角汇入为主(84.25%、80.14%),其次为锐角汇入(13.70%,13.70%),中部以直角汇入为主(71.35%、66.45%),后部均以钝角汇入(100%);102例中发现135个蛛网膜颗粒,均小于5 mm,大部分(68.89%)与桥静脉无关,部分(22.22%)位于桥静脉狭窄处。 结论 VCTDSA是显示上矢状窦旁桥静脉的理想影像学方法,可从不同角度充分显示其解剖形态及与蛛网膜颗粒的关系,有助于临床各种纵裂间手术时保护桥静脉。 |

| Objective To investigate the anatomic appearance of bridging veins draining into superior saggital sinus and the relationship between arachnoid granulations and bridging veins with volume CT digital subtraction angiography (VCTDSA). Methods VCTDSA data of 102 patients were analyzed. The number, morphology, size, converging angle and location to superior sagittal sinus of bridging vein were observed, as well as the location, size of arachnoid granulations and relationship with bridging vein. Results There were 873 bridging veins in 102 patients, most on middle (about 2 branches per side), and least on posterior part (about 1 branch per side).The anterior part mostly centralized nearby original point. There were three shapes of bridging vein: Tube or ribbon shape (65.95%), significantly on anterior and posterior part; flat and irregular shape (24.73%), mainly on the middle; flat and ethmoidal foramen shape (9.31%), most on the middle. Shape of bridging vein debouchement of superior sagittal sinus was most on sinus-basilar in the anterior part, and sinus-central in the middle part, while sinus-inferior in posterior part. Debouchement angle of the bridging vein to superior sagittal sinus was most straight angle (84.25%, 80.14%) on anterior part, secondly, the angle was acute angle (13.70%, 13.70%); straight angle (71.35%, 66.45%) were observed on middle part; and obtuse angle always were seen on posterior part (100%). Totally 135 arachnoid granulations were detected in 102 patients, all less than 5 mm, most of them (68.89%) had no relationship with bridging vein, some of them (22.22%) on the stenosis of bridging vein. Conclusion VCTDSA is an ideal imaging method to show the anatomic features of bridging veins draining into superior saggital sinus. The anatomic form and the relationship with arachnoid granulations can be completely displayed in different views with VCTDSA, and this may be useful for protection of bridging veins in the interhemispheic approaches in clinical. |
