A new method to demonstrate the renal arteries is presented. It consists of taking with a Synchroplan apparatus simultaneous tomographic sections during the aortic and arterial stage of intravenous urography (IVU). Direct visualization of the vessels avoids the false negative results of IVU alone in investigations of renovascular lesions, such as bilateral stenosis of the renal artery, stenoses with few functional disorders, aneurysms and associated arterial and urinary lesions. Lesions of the infra-renal portion of the aorta and of the splanchnic arteries are also visualized. In a series of 37 patients investigated for renovascular hypertension, the new method proved more sensitive, more specific and of higher predictive value than conventional IVU. In another series of 19 patients who had undergone revascularization of the kidneys, the authors were able to obtain good visualization of the new vascular system and to establish correlations between morphological features and the effects of hypertension. The method therefore appears to be valuable in detecting renovascular lesions in arterial hypertension, monitoring renal artery lesions and following up patients with surgical revascularization.
本文介绍了一种显示肾动脉的新方法。该方法是在静脉尿路造影（IVU）的主动脉期和动脉期，使用同步平面装置同时进行断层扫描。血管的直接显影避免了仅靠IVU在肾血管病变检查中出现的假阴性结果，这些病变包括肾动脉双侧狭窄、功能障碍轻微的狭窄、动脉瘤以及相关的动脉和泌尿系统病变。主动脉肾下段和内脏动脉的病变也能显影。在对37例肾血管性高血压患者进行的系列研究中，新方法被证明比传统IVU更敏感、更具特异性且预测价值更高。在另一组19例已接受肾脏血管重建术的患者中，作者能够很好地显示新的血管系统，并建立形态学特征与高血压影响之间的关联。因此，该方法在检测动脉性高血压中的肾血管病变、监测肾动脉病变以及对接受手术血管重建的患者进行随访方面似乎很有价值。
