CT angiographic study of the cerebral deep veins around the vein of Galen

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 ICY at its beginning and termination points (P <0.01). The ICY 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 degrees (77.2 +/- 18.00). 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.

Automated summary

Research on the anatomy of cerebral deep veins around the vein of Galen is important and clinically significant. A retrospective study of CDVs in Chinese patients was conducted using CTA, with findings showing variations in venous structure. Preoperative understanding of these variations can aid in endovascular treatments.
