Research on the anatomy of cerebral deep veins (CDVs) around the vein of Galen (VG) is very important and has fundamental clinical significance. Large-scale anatomical studies of CDVs using computed tomography angiography (CTA) are rarely reported. A retrospective study of the CDVs around the VG was conducted in Chinese patients of Han nationality. One hundred cases were included in the final analysis. The patients were aged from 17 to 78 years (mean: 42.3 years). Also, 46% of the patients were female. The diameter of the internal cerebral vein (ICV) at its beginning and termination points ranged from 0.4 to 2.8 mm (1.49 ± 0.39 mm) and 0.4 to 3.5 mm (2.05 ± 0.47 mm), respectively. There was statistical significance regarding the diameter of the ICV at its beginning and termination points (P <0.01). The ICV length ranged from 28.5 to 47.9 mm (36.86 ± 3.74 mm). The length of the straight sinus (SS) ranged from 30.2 to 57.8 mm (43.6 ± 6.37 mm). The length of the VG ranged from 1.5 to 41.8 mm (9.30 ± 4.76 mm). The angle at the VG and SS transition area ranged from 25.4 to 110.6° (77.2 ± 18.0°). This study was a meaningful attempt to conduct anatomical research of CDVs using CTA. Preoperative familiarity with the normal venous structure and its variation around the VG would be helpful for endovascular treatment.
关于大脑深静脉（CDVs）在Galen 静脉（VG）周围的解剖学研究非常重要，具有重要的临床意义。使用计算机断层血管造影术（CTA）对 CDVs 进行大规模解剖研究很少有报道。本研究对汉族中国患者的 VG 周围 CDVs 进行了回顾性研究。最终纳入 100 例患者进行分析。患者年龄 17-78 岁（平均年龄：42.3 岁），其中 46%为女性。内脑静脉（ICV）起始点和终点处的直径范围为 0.4-2.8mm（1.49±0.39mm）和 0.4-3.5mm（2.05±0.47mm），差异有统计学意义（P<0.01）。ICV 长度范围为 28.5-47.9mm（36.86±3.74mm）。直窦（SS）长度范围为 30.2-57.8mm（43.6±6.37mm）。VG 长度范围为 1.5-41.8mm（9.30±4.76mm）。VG 和 SS 过渡区的角度范围为 25.4-110.6°（77.2±18.0°）。本研究是使用 CTA 对 CDVs 进行解剖学研究的一次有意义的尝试。术前熟悉 VG 周围正常静脉结构及其变异，有助于血管内治疗。
