For the last two decades the most common method of radiographic study of the venous system of the lower limbs has been ascending phlebography, by injection of contrast material in a superficial vein on the dorsum of the foot. We report our own experience with another approach, using a large field technique on recumbent patients, with elevation of the limbs, thus taking advantage of gravity. The contrast injection is usually made in a more distal superficial vein of the foot after a tiny cut-down. Excellent results are consistently obtained in demonstrating all the deep veins, including the iliac vessels. The same principles may be applied to upper limb phlebography.
在过去二十年中，下肢静脉系统放射学研究最常用的方法是上行静脉造影，即将造影剂注入足背的浅静脉。我们报告了我们使用另一种方法的经验，即对卧位患者采用大视野技术，抬高肢体，从而利用重力作用。造影剂注射通常在微小切开后在足部更远端的浅静脉进行。在显示包括髂血管在内的所有深静脉方面始终能获得极佳的效果。相同的原理也可应用于上肢静脉造影。
