摘要
目的了解肾动脉造影在小肾癌诊断中的应用价值。方法回顾性分析经肾动脉造影诊断的肾肿瘤患者76例。肾肿瘤最大径均小于3 cm,均经术后病理检查确诊。分析患者术前造影检查资料及相应诊断结果,并与术后病理结果比较。结果 76例中,术前经选择性肾动脉造影诊断为肾癌68例,均为富血管肿瘤,并有较典型的恶性肿瘤血管造影表现,考虑为良性病变8例,其中富血管肿瘤3例,主要为肾血管平滑肌脂肪瘤,其余5例为少血管性肿瘤。术后病理检查诊断为肾细胞癌67例,术前肾动脉造影诊断为肾癌的68例中,3例为良性病变,术前考虑为良性病变的8例中(包括3例肾血管平滑肌脂肪瘤),2例为肾细胞癌。结论肾动脉造影对富血管的小肾癌的诊断准确率高,具有较高的诊断价值,但对少血管性小肾细癌,则需结合其他检测手段综合考虑。
Objective To discuss the clinical value of renal arteriography in diagnosing the small renal carcinomas. Methods Clinical information of 76 patients with angiography- proved small renal carcinoma were retrospectively analyzed. The patients included 52 males and 24 females, and the patient＇s age ranged from 28 to 78 years with an average of 55 years. The largest diameter of the renal tumors was smaller than 3 cm. All the specimens were sent for pathologic examination. Preoperative angiographic findings were compared with postoperative pathologic results. Results Of the 76 patients, preoperative diagnosis of renal carcinoma was made by renal arteriography in 68, all of which were rich in vascularity with rather typical angiographic features of a malignant tumor. Among them, 8 patients were diagnosed as a benign lesion, and three lesions were rich in vascularity, which were mainly renal angiomyolipomas. In the remaining 5 patients, the lesions were hypovascular ones. Pathologically, renal carcinoma was diagnosed in 67 patients. Of the 68 patients who were diagnosed as renal carcinoma by renal arteriography before operation, three actually suffered from benign lesions. Of the 8 patients who were considered to have benign lesions before operation, 6 had benign lesions, including renal angiomyolipomas （n = 3）, and the other two had renal clear-cell carcinoma. Conclusion Renal arteriography carries higher diagnostic accuracy for small renal carcinoma that is rich in vascularity, although combination use of other diagnostic means is needed for the diagnosis of hypo-vascular small renal carcinoma.
