In conventional aortography, all branches of the aorta may be visible, making interpretation difficult. By a new angiographic method, only the dorsal and lateral branches of the aorta are made visible, without the appearance of ventral branches such as the celiac, superior mesenteric, and inferior mesenteric arteries. The contrast medium is injected slowly through a closed-end catheter with side holes arranged on one side only. The best conditions for such angiography were as follows: a catheter with five side holes (the two proximal holes were small) with neighboring holes 3 cm apart, injection of 12 ml of contrast medium at the rate of 4 ml/second, and the catheter placed next to the dorsal wall of the aorta. The catheter could be held in this position when the aorta was curved provided that the head of the catheter was spiral and the next portion was convex. In clinical angiography, 24 patients suspected to have retroperitoneal or spinal disease were examined. The dorsal branches of the aorta were seen but the ventral branches were not seen in 19 of the patients. This method was superior to conventional aortography for the evaluation of lumbar arteries and the main trunks of renal arteries. In nine patients, the evaluation of abnormal findings such as feeding arteries was easier by this method than by conventional aortography.
在传统主动脉造影中，主动脉的所有分支都可能显影，这使得解读变得困难。通过一种新的血管造影方法，仅使主动脉的背侧和外侧分支显影，而不会出现诸如腹腔干、肠系膜上动脉和肠系膜下动脉等腹侧分支。造影剂通过仅在一侧设有侧孔的封闭端导管缓慢注入。这种血管造影的最佳条件如下：带有五个侧孔（两个近端孔较小）的导管，相邻孔间距为3厘米，以4毫升/秒的速度注入12毫升造影剂，并且导管放置在主动脉后壁旁边。当主动脉弯曲时，如果导管头部呈螺旋状且下一部分呈凸形，则导管可以保持在这个位置。在临床血管造影中，对24例疑似患有腹膜后或脊柱疾病的患者进行了检查。在19例患者中可见主动脉的背侧分支但未见腹侧分支。这种方法在评估腰动脉和肾动脉主干方面优于传统主动脉造影。在9例患者中，通过这种方法评估诸如供血动脉等异常发现比传统主动脉造影更容易。
