The widths of the systemic vessels extending from the thoracic inlet to the heart (the vascular pedicle) and of the azygos vein were measured in 83 normal volunteers and 42 patients with cardiac disease. Mean vascular pedicle width ( VPW ) (erect) was 48 +/- 5.0 mm and correlated well with body weight (r = 0.64) and surface area (r = 0.62). Rotation to the left reduced VPW and to the right increased it. Inspiration and expiration caused little change. The supine VPW increased an average of 20% (47 +/- 37% to the compliant venous right side and 7 +/- 48% to the less compliant arterial left). Supine azygos width (AW) increased 105 +/- 47%. Mean erect AW was 5.14 +/- 1.36 mm. AW did not correlate significantly with anthropomorphic characteristics. Because VPW correlates with the patient's physique, its normality can be estimated within clinically useful limits by inspection. Since AW has no such correlation, serial changes are of more value than initial absolute values.
在83名正常志愿者和42名心脏病患者中测量了从胸廓入口延伸至心脏的体循环血管（血管蒂）的宽度以及奇静脉的宽度。平均血管蒂宽度（VPW）（直立位）为48±5.0毫米，与体重（r = 0.64）和体表面积（r = 0.62）密切相关。向左旋转会使VPW减小，向右旋转则使其增加。吸气和呼气引起的变化很小。仰卧位VPW平均增加20%（向顺应性较好的右侧静脉增加47±37%，向顺应性较差的左侧动脉增加7±48%）。仰卧位奇静脉宽度（AW）增加105±47%。平均直立位AW为5.14±1.36毫米。AW与人体测量学特征无显著相关性。由于VPW与患者的体格相关，通过检查可在临床有用的限度内估计其正常范围。由于AW不存在这种相关性，所以连续变化比初始绝对值更有价值。
