摘要:

目的 通过对胸椎椎基静脉孔(BF)的数字化观测,明确其解剖位置、形态特点,为临床应用提供参考依据。  方法  40例成人胸椎CT扫描数据,运用Mimics15.0软件重建测量BF宽(BFW)、高(BFH)、深(BFD);BF距椎体上、下终板(VHU、VHB)和左、右缘(VWL、VWR)间距;观察其在椎体中的位置与形态。  结果 (1)胸椎BFW总体呈V形分布,T6为最小值(3.69±1.29 mm); BFH在T1~3趋于平稳,T4~6渐减,T7~11渐增;BFD在T1~3渐增,T3~10趋于平稳,T10~12渐减。(2)BF距上终板与下终板间距总体呈上升趋势,T1最小:VHU为(7.05±1.27) mm,VHB为(7.21±0.87) mm,T12最大:VHU为(11.00±1.10) mm,VHB为(11.37±1.48) mm;距左、右缘间距在T1~4渐减,T5~12渐增,T4最小:VWL为(10.50±1.40) mm,VWR为(10.81±1.66) mm,T12最大:VWL为(15.74±2.55)mm,VWR为(16.23±2.82)mm。   结论 胸椎椎体后壁近中央处均存在BF,其形态结构复杂且在不同个体、不同节段中均存在差异。BF在T1~8、T10、T11位于椎体后壁近中央,T9和T12稍偏向左侧。BF在T1~3、T10~12形似棱锥体形,而T4~9形似长方体形。

Abstract:

Objective By digitizing the measurement of the basivertebral foramen for thoracic vertebrae to discuss the basivertebral foramen (BF) of thoracic spine (T1~12), including the anatomical location, the form and the differences between different vertebral bodies. Methods The 40 healthy adults underwent multi-slice CT thin-layer scan and sagittal CT reconstruction images, using Mimics 13.0 software measurement; the following indices were observed: BF wide (BFW), deep (BFD), high (BFH) in the absolute value; the distance of BF to the vertebral end plates and to the left and the right vertebral edges was measured;  the location and shape of the vertebral foramen was observed. Results (1)BFW assumed an overall V-shaped distribution. The min was T6;  BFH was steady in T1~3, gradually declining in T4~6, and gradually increasing in T7~11; BFD was graduallyincreasing in T1~3, steady T3~10 , and gradually decreasing in T10~12.(2)Vertebral body up(VHU) and vertebral body below(VHB) of BF are gradually increasing. The min was T1(VHU 7.05±1.27 mm,VHB 7.21±0.87 mm), the max was T12(VHU 11.00±1.10 mm,VHB 11.37±1.48 mm). Vertebral body left (VWL) and vertebral body right(VWR) were gradually decreasing in T1~4, gradually increasing in T5~12, the min was T4(VWL 10.50±1.40 mm,VWR 10.81±1.66 mm), the max was VWL in T12 (VWL 15.74±2.55 mm,VWR 16.23±2.82mm). Conclusion (1) There are many BF inequality of size existent in the middle of vertebral thoracic body; These construction are complex and have difference between each individual segments. (2)The shape of BF in sagittal and coronary sections are anomalism, triangle, rectangle and 11% visible osseous separation. (3)The BF in T1~8、T10、T11 adjoin the centre of vertebral body's posterior paries, and T9 and T12 have left deviation.
