Clinical Applications

By selective catheterization of the segmental arteries, the anterior radicular feeders of larger caliber and their continuation into corresponding segments of the anterior spinal artery can be demonstrated in the normal spinal cord. Visualization of the posterior radicular feeders as well is only occasionally possible (Fig. 50 b). Visualization of longer vessel courses is hampered not only by technical limitations of radiology, but also by inflow of noncontrasted blood from other supply territories above and below. This is also the reason why demonstration of the draining veins is difficult as long as only small amounts of contrast medium (approx. 2 ml) are injected. A radicular artery and its continuation into a descending branch of the anterior or posterolateral spinal artery is easily identified due to its typical “hairpin” course (Figs. 48, 50–52).
