【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Mimics 15.0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,T_6为最小值(3.69±1.29 mm);BFH在T_(1-3)趋于平稳,T_(4-6)渐减,T_(7~11)渐增;BFD在T_(1~3)渐增,T_(3~10)趋于平稳,T_(10~12)渐减。(2)BF距上终板与下终板间距总体呈上升趋势,T_1最小:VHU为(7.05±1.27)mm,VHB为(7.21±0.87)mm,T_(12)最大:VHU为(11.00±1.10)mm,VHB为(11.37±1.48)mm;距左、右缘间距在T_(1~4)渐减,T_(5~12)渐增,T_4最小:VWL为(10.50±1.40)mm,VWR为(10.81±1.66)mm,T_(12)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T_(1~8)、T_(10)、T_(11)位于椎体后壁近中央,T_9和T_(12)稍偏向左侧。BF在T_(1~3)、T_(10~12)形似棱锥体形,而T_(4~9)形似长方体形。
[Abstract]:Objective to determine the anatomical location and morphological characteristics of thoracic vertebral foramen foramen (BF) in order to provide reference for clinical application.Methods the CT scanning data of 40 adult thoracic vertebrae were reconstructed with Mimics 15.0 software to measure the distance between BF BFW, BFH, BF, VHUV VHBB and VWLL VWR, and to observe the position and shape of VWL VWR in vertebral body.The maximum of VHU was 11.00 卤1.10mm and VHB was 11.37 卤1.48mm.The distance between the right margin and the right edge is gradually decreasing.) the minimum VWL is 10.50 卤1.40 mm / L and the VWR is 10.81 卤1.66 mm / T / T _ 12) the maximum VWL is 15.74 卤2.55 mm VWR is 16.23 卤2.82 mm / m.Conclusion there is BF in the proximal central part of the posterior wall of the thoracic vertebrae. The morphology and structure of BFare complex in different individuals, and there are differences in the different segments. BF is located in T1T / T / T / T / T / T ~ (11)) and is slightly tilted to the left / left side of T _ (9) and T _ (12)) and is similar to the shape of pyramidal body in T _ (1 / 3) / T _ (10 / 10 / 12) / T _ 1 / T _ 3 / T _ (10 / 12).And T _ T _ T _ 4 ~ (9) is cuboid in shape.
