Nine patients with renal tumors were studied by intraarterial digital subtraction arteriography (IADSA). Embolization was performed in six patients. IADSA was evaluated on the following practical points: vascular mapping, renal vein visualization, and embolization. Vascular mapping by IADSA was satisfactory in eight patients. The limitation of the field of view was the major restricting factor, and a second opacification was necessary in two cases. One case with multiple renal arteries was unacceptable as the lowest renal artery was missed. Renal vein visualization by IADSA with renal artery injection was not reliable due to misregistration artifacts caused by bowel gas. Embolization with IADSA was satisfactory. Significant reductions in contrast load and procedure time were achieved. IADSA was found to be an effective tool in vascular mapping and embolization of renal tumors. Selective renal arteriography to visualize renal veins was better performed with conventional techniques.
对9例肾肿瘤患者进行了动脉内数字减影血管造影（IADSA）研究。6例患者进行了栓塞治疗。对IADSA从以下几个实际要点进行评估：血管造影、肾静脉显影和栓塞。8例患者通过IADSA进行的血管造影结果令人满意。视野限制是主要制约因素，2例患者需要进行二次造影。1例有多支肾动脉的患者因最低位肾动脉未显示而不理想。由于肠道气体导致的配准伪影，经肾动脉注射的IADSA对肾静脉的显影不可靠。IADSA栓塞效果令人满意。造影剂用量和操作时间显著减少。发现IADSA是肾肿瘤血管造影和栓塞的有效工具。用传统技术进行选择性肾动脉造影以显示肾静脉效果更佳。
