下腔静脉的心血管造影测量显示正常平均口径为 23.9 毫米（SE±0.68）。在伴有右心衰竭或扩大的心血管疾病中，平均口径增加至 30.5 毫米。 （SE [正负] 0.51）。患有先天性心脏病的儿童，平均口径为17.1毫米。 （SE±0.44）。患有先天性心脏病伴右心衰竭或扩大的下腔静脉的口径可以通过以下公式粗略预测：口径 = 7.7 log10 年龄 - 16.5。这个公式不适用于成人群体，无论是正常人还是患有后天性心脏病的人，因为口径不会随着年龄的增长而显着增加。正常上腔静脉的口径是下腔静脉的一半。对于心血管疾病，该比率增加至 0.6 至 0.7。在任意选择的一组患有获得性心脏病但没有右心衰竭或扩大的临床、伦琴或心血管造影体征的患者中，上腔静脉与下腔静脉的比率为0.64。这表明即使没有明显的右心衰竭，血流动力学变化也存在。
Angiocardiographic measurement of the inferior vena cava revealed the normal mean caliber to be 23.9 mm (SE [plus or minus]0.68). In cardiovascular disease with right heart failure or enlargement, the mean caliber increased to 30.5 mm. (SE [plus or minus] 0.51). In children with congenital heart disease, the mean caliber is 17.1 mm. (SE [plus or minus]0.44). The caliber of the inferior vena cava in the presence of congenital heart disease with right failure or enlargement may be roughly predicted from the following formula caliber = 7.7 log10 age - 16.5. This formula is not applicable to the adult groups, either normal or with acquired heart disease, because the caliber does not significantly increase with age. The caliber of the normal superior vena cava is half that of the inferior vena cava. With cardiovascular disease this ratio increases to 0.6 to 0.7. In an arbitrarily selected group of patients with acquired heart disease without clinical, roentgen, or angiocardiographic signs of right heart failure or enlargement, the superior-to-inferior venae cavae ratio was 0.64. This suggests that even in the absence of manifest right heart failure, hemodynamic changes exist.
