为探讨肾动脉数字减影血管造影（DSA）对肾癌的诊断和介入治疗的临床价值，应用DSA对19例疑为肾肿瘤的患者进行诊断和介入治疗，并同期施行B超、静脉尿路造影（IVU）、CT检查，结果19例经DSA检查均诊断为肾癌，优于B超、CT及IVU；17例行介入治疗，均可见肾动脉分支完全闭塞，给手术治疗提供重要帮助。认为肾动脉DSA能明确了解肾肿瘤血供状况及形态，诊断准确率高，且对介入治疗和手术方案的选择及预后判断具有重要意义。
To investigate the clinical value of renal artery digital subtraction angiography (DSA) in the diagnosis and interventional treatment of renal cell carcinoma, 19 patients with suspected kidney neoplasm were diagnosed and treated by DSA. 19 cases were diagnosed as renal cell carcinoma by DSA, which was superior to B-ultrasound, CT and IVU. All the 17 cases were completely involved in the interventional therapy, which provided complete help for the surgical treatment. Renal artery DSA can clearly understand the renal tumor blood supply status and morphology, high diagnostic accuracy, and interventional treatment and surgical options and prognosis of great significance.
