材料为成尸30具(男23,女7),结果如下:1 奇静脉行径 奇静脉全程居脊柱右侧者较为少见,仅3例,占10%.奇静脉中段向左凸至脊柱中线前方者最为多见,共15例,占50%.向左凸至脊柱中线前方的部分,上可达T_1水平,下可至T_(11)水平,大多数居T_(7～9)的前方.其中2例居1个胸椎体前方(13.3%),8例居2个胸椎体前方(53.3%),5例居3个胸椎体前方(26.6%)1例居4个胸椎体前方(6.6%).奇静脉中段越过中线凸至脊柱左侧者次之,共12例,占40%.其位于脊柱左侧的部分.上可达T_6水平,下可至T_(10)水平.大多数在T_(7～9)的左侧,其中2例居1个胸椎体的左侧(16.6%),1例居2个胸椎体的左侧(8.3%).9例居3个胸椎体的左侧(75. 0%).
Materials for the adult 30 (male 23, female 7), the results are as follows: 1 azygos vein azygos whole spine on the right side of the spine are rare, only 3 cases, accounting for 10% .Six aortic mid-left convex to the midline of the spine The most common, a total of 15 cases, accounting for 50% of the left convex to the front part of the midline of the spine, up T_1 level, down to T_ (11) level, most of the home T_ (7 ~ 9) in front of. Among them, 2 cases were located in front of anterior thoracic vertebrae (13.3%), 8 cases were in front of 2 thoracic vertebrae (53.3%), 5 were located in front of 3 thoracic vertebrae (26.6%), 1 case were 4 thoracic vertebrae In the anterior part (6.6%), the middle part of the azygos vein crossed the midline to the left of the spine, followed by 12 cases (40%), located on the left side of the spine, up to T_6 and down to T_ (10) , Most of them were on the left side of T 7 (7-9), two of them were on the left side of one thoracic vertebra (16.6%) and the other one was on the left side of two thoracic vertebrae (8.3%). Left side of three thoracic vertebrae (75.0%).
