Phlebographic visualisation offers the highest spatial resolution of all imaging methods both in respect of veins of the leg and pelvis and of the abdomen. Phlebography offers optimal conditions for assessing morphological changes at the veins and in their direct neighbourhood. No quantitative information is available via phlebography if haemodynamics are disturbed; qualitative information is yielded merely to a restricted extent (by assessing flow velocity and collaterals). Direct sanguinous measurement of venous blood pressure is particularly suitable for the quantitative and qualitative assessment of disturbed haemodynamic conditions; in this respect it stands out among the function tests based on the employment of apparatures. If it is combined with phlebography, it is possible not only to optimise the diagnostic yield in the hands of one investigator, but also to reduce the invasiveness of both methods to one single puncture, since the puncture needle is at the same time also an instrument to measure the pressure. The article points out the possibilities and limitations of combining a) ascending phlebography of the leg and pelvis with peripheral venous pressure measurement (phlebodynamometry) and b) visualisation of the veins of the pelvis and vena cava inferior with central sanguinous venous pressure measurement (CP). Indicatious and technical execution are described.
静脉造影成像在腿部、骨盆和腹部静脉的所有成像方法中具有最高的空间分辨率。静脉造影为评估静脉及其紧邻区域的形态变化提供了最佳条件。如果血流动力学受到干扰，静脉造影无法提供定量信息；只能在有限程度上获得定性信息（通过评估流速和侧支循环）。直接测量静脉血压特别适合对血流动力学紊乱情况进行定量和定性评估；在这方面，它在基于仪器使用的功能测试中表现突出。如果将其与静脉造影相结合，不仅可以提高单一检查者的诊断效率，还能将两种方法的侵入性降低至单次穿刺，因为穿刺针同时也是测量压力的仪器。本文指出了以下两种结合方式的可能性和局限性：a）腿部和骨盆的上行静脉造影与外周静脉压力测量（静脉压力测量法）相结合，以及b）骨盆静脉和下腔静脉成像与中心静脉血压测量（CP）相结合。文中还描述了适应证和技术操作方法。
