During inferior venacavography the tip of the catheter perforated the wall of the common iliac vein and entered the epidural space of the adjacent large lumbosacral trunk. Anatomically it is only at the level of the first sacral segment that the vein and nerve lie in very close proximity. Simultaneous opacification of the venous system and the epidural space resulted. A severe, temporary pain occurred upon the injection of the epidural space. There was no residual neurologic deficit.
Koehler et al. (1962) studied this question.
